Colour Conundrum pt. 1: "Kodak 5"



Colour Photography and me, sometimes I just don't know. It isn't that I have issues with it as a creative medium. Sure, black and white is it for me 90% of the time but there are times when colour is an important element. The trouble is more of a practical thing. It's easy enough to carry and extra back loaded with colour film for just those occasions. The problem is what to do with the stuff once it's been shot. Gone are the days when it was a simple matter to find a local business that could handle the processing for you. The answer should be simple enough - I know my way around the darkroom (I can do it with my eyes closed!) and colour chemistry isn't that hard to get my hands on. The trouble is a batch of C-41 chemistry only lasts for a couple of months once mixed. On average over that time span I'll probably not even shoot a single roll of colour. If I were to shoot E-6, which I'd love to, that's even worse. 

A popular option these days is to ship film away to a lab but shipping one roll at a time adds a lot of expense and if I'm going to wait until I have several rolls I might as well just do it at home. I have all the stuff after all. And so it is this is the option that I have gone with. Sounds like a near perfect plan given the circumstances, right?

Well... maybe. I'm no stranger to the C-41 process. It's fixed, predictable if you stick to a few simple guidelines with no adjustments required in time or temperatures to match a particular film, they all get processed the same way. In many ways it's easier and faster than processing a typical black and white film. Still, for reasons I'm sure had little to do with problems or inconsistencies at the development stage, recent results have fallen a little outside what I was expecting.

To begin with I had 6 rolls of film to develop: One roll each of Kodak Portra 400 and Ektar in 120, two rolls of Agfa Optima 400 in 220 that expired some time in the late 90's, a 120 roll of Lomo 100 and a roll of Fuji Superia 800 that went though one of my Nikons though I can't remember which. Together these represented all the colour film that that completed it's journey through my various cameras roughly over the past year, though in many cases they seem to have been sitting in camera for a much longer time than that. All were developed in the same batch of a 1L Unicolor C41 kit that I ordered from the Film Photography Project. It was recently mixed though I had the kit sitting around as dry chemicals for about a year and a half which should be well within expected shelf life for the unmixed chemicals. This is a two part series and here I'll be discussing the results from the Kodak emulsions and I'll follow up next time with some thoughts on all the rest.

Given that these were the most mainstream of the emulsions and, except for the Lomo, the freshest, these films gave me the most surprising results. Both of these went through my RB67. Like the other two medium format SLR systems I own it has interchangeable film magazines allowing me to switch mid-roll from one film to another and I've used this capability in the usual way to switch from the usual black and white to colour film when it seems appropriate. For the record it has always been a consistent performer the black and white images I have made with it come out just fine.

Portra 400

The Portra 400 had been loaded into the camera no more recently than 2015. I know this only because it contains a particular image, the black and white version of which first appeared in my portfolio in that year. There were only 4 (out of a possible 10) shots on the roll but it's been so long since I shot it I can't remember what might have happened that it was never completely shot. That's just how seldom I use that camera to shoot colour. For all the time it's been sitting there it's still surprising that there were such obvious issues with it. All of the images showed some degree of odd mottling. The first image was by far the strangest with a series of discoloured lines running the width of the film. Here's the straight scan:



The remaining exposures weren't nearly so affected but this odd mottling was evident in all of the exposures. Yes it's been sitting around for a while but I've developed film much older than this, including some that I'll discuss in the next instalment that was developed at the same time in the same batch of chemistry without any such issues. It's hard to say what's causing this. It's clearly not any sort of light leak as it seems to be just a variation in colouration and is worse on the first frame that would have been sitting closest to the centre of the exposed roll. One clue might come from the last of the 4 frames in which the otherwise random mottling shows one clear pattern. A cropped in image of this should make it plain enough...

And in case it's not clear where this might have come from here's a portion of the backing paper from that same roll:

I can only guess that this is the result of some sort of chemical reaction with the ink used to print the frame markings on the backing paper though curiously, to me anyway, there are no markings on the backing paper to match the lines seen in the first frame. Maybe the readership has some better suggestion?

I liked this final frame though, so just I decided to take the scan and clean things up as best I could digitally. The "Kodak 5" was gotten rid of easily enough but you don't have to look too closely to see the mottling.  If you can ignore this though I'd say I like the shot



Ektar

The second film that had gone through the RB67 was a roll of Ektar 100. It came out of the camera several months ago. If there were thoughts that the issues with the roll of Portra might have had something to do with whatever the problem must have been that caused me to shoot less than half of it most were dispelled by comparing it with this roll. Though it hadn't been sitting on the shelf nearly as long as the Portra, it also had a random mottling pattern throughout the roll and here the first three frames were plagued with particularly prominent lines that again spanned the width of the film, and again it was the same sort of greenish discolouration. Here is the third frame from that roll.


Image anomalies aside though it seems to me this roll came out much differently than any of the others. Ektar is known for it's reasonably bold colours but these seem punchy beyond reason to me. I mean it's still a fairly standard film not unsuited for standard portraiture. For example, while I'm no geologist I'm sure the rocks in this images are practically identical to the ones in the example Portra image above it that was taken about 30km away along the Lake Erie shore. They certainly don't strike me as being this sort of Mars red when I look at them. Curious indeed.

If Kodak C-41 films were generally problematic like this then I'm sure my experiences here would be old news. On the other hand if something is wrong on my end like I got a bad batch of chemistry or maybe I've just really gotten out of touch with good colour processing practice then you'd expect these problems to carry over to the other rolls I developed in this batch as well. In my best go at creating a cliff hanger then, that's what I'll look at in the next instalment so please stay tuned.

Meet the Beast: Part IV

At long last it's time to wrap up this series with a few final thoughts on the RB67 and how it might or might not be a good fit for photographers in this day and age interested in a classic analog medium format system. As I hope I've made clear to this point these cameras have a lot going for them - they're ruggedly built and designed to perform to professional standards, but drastic changes in the way that the professionals these cameras were designed for work has flooded the market with used systems, often in top condition, priced lower than the most basic of entry level DSLRs. Why would anyone with a fondness for shooting film and an eye towards the increasingly popular medium format think of looking at anything else? Well, there may be a few reasons.

The price of the 17% gain in negative size you get with the Mamiya RB67 (left) is an added burden in terms of size and weight that is much higher percentage wise compared to a camera like the Bronica S2A on the right.

My closing comment in the last episode (the text portion, not in the video) let you in on the fact that I've been using a different camera lately. That's it on the right in the photo above, a classic Bronica S2 or S2A (there's been some debate about which of the two models this actually is, they're virtually identical). I put it there for comparison though, it's still all about the Mamiya. As you no doubt have guessed the comparison is all about size.

The Bronica is a fairly typical 6x6 cm square medium format SLR. Though it's a bit heavier, in terms of physical dimensions it's roughly the size of the more widely recognized Hasselblads such as the 500cm introduced at about the same time. To be fair the RB67 will produce somewhat larger 6x7 cm negatives, but the slight increase in negative size comes at the price of an anything but slight increase in equipment bulk. It's not just a weight increase either, the RB takes up more shelf space and requires a roomier camera bag when you bring it into the field.  The problem is only compounded when you add lenses and other accessories that are similarly scaled up compared to most other popular medium format gear.

Is all the extra bulk necessary to go from 6x6 to 6x7 with a medium format SLR? Another well known 6x7 format SLR is the Pentax 6x7 (later to become the Pentax 67). Though they shared the RB's format, these cameras had a very different design philosophy. Gone is the revolving back design, the integrated bellows focusing and the in-lens shutter, these cameras could only be described as scaled up 35mm SLRs. With a waist level finder and normal lens a Pentax 67 would come in at around 2kg, about half way between a similarly equipped Hasselblad and an RB67. The layout of these cameras however limited the usefulness of waist level viewing, so prism finders are the norm for the Pentax's, bringing the total weight just shy of our Mamiya. Add to this the fact that vertical shooting with the Pentax will require a heavier tripod and the RB is arguably the easier camera to carry and handle in the field.

Carrying an RB67 to get this image rather than a typical square format SLR involved a huge penalty in terms of weight sheer size, only to end up cropping the result down to the square dimensions a smaller camera would have given me.

Whether the larger negative is worth it or not is of course a personal question, one that I had to answer for myself. There are times that for particular images I've really appreciated it. At least as frequently however I end up cropping an image square, completely negating any advantage carrying all that extra bulk gave me, not to mention the extra bit of wasted film that gives me 10 rather than 12 exposures per roll. The appearance of a new square format camera in my collection is a good clue to the direction I've been leaning as of late.

That said it was actually one of the RB67s other shortcomings, a seemingly minor thing, that got me to thinking about moving to a square format system. Back in part II of the series I discussed the normal/mirror up switch on the lens and how leaving it in the wrong position can leave a photographer firing away with nothing to indicate the shutter wasn't opening until the blank film emerged from the processing tank. This was not a problem so long as I stuck to my usual "slow photography" M.O. of shooting tripod mounted, locking the mirror and using a cable release. For reasons I'll save for a future episode I've been thinking of expanding my approach in such a way that, given my predisposition for absent minded oversight, would inevitably find me staring at clear pieces of film where anxiously anticipated images should be. And of course there's also the sheer size of the RB, did I mention the size?

While in my experience the range of Mamiya Sekor lenses available for the RB67 (Sekor is Mamiya's house optical brand) are entirely up to professional standards optically, if you make the usual assumption that bigger lenses are faster lenses you may be disappointed. Normal lens for most medium format SLRs typically have an f/2.8 maximum aperture and it's not unusual for there to be a number of equally fast lenses in the range. Though lenses in the RB range are larger than those for rival systems in about the same proportion as all the other components, the fastest lens anywhere in the RB67 system has an f/3.5 maximum aperture, and no lens outside the "normal" range is any faster than f/4.5. This isn't something I consider a real disadvantage when in slow photography mode (though paying a penalty in both size and speed doesn't necessarily sit well) but it does start coming into play when I start envision radical concepts like purposely leaving the tripod in the car.

Though the Mamiya RB67 was always considered a camera for the professional photo studio this is by no means an indication that it's not up for use outside the controlled indoor environment. In fact it's quite the opposite. Their failure resistant all mechanical construction mean these cameras are anything but delicate. As so many of them outlasted their usefulness as the computer age brought more speed to the business of photography than a camera like the RB could keep up with it's no surprise that so many of them have found their way into the kit bags of photographers looking to bring them further afield. Doing so requires a willingness to accept the limitations that once made photographers look at the RB as cameras of the controlled environment, their size, their weight and the methodical approach using one demanded.

Those limitations are still present, but they're not insurmountable. After all, photographers have been carrying much heavier and slow to use large format cameras into some of the least accessible locations in the world for over 150 years. With a good carrying system and a strong back (or failing that a good chiropractor on speed dial) these cameras will put up with almost any environment a photographer hearty enough to haul it that far is likely to tolerate. Once there a willingness to take the time the RB67 demands can result in images that make it all worth while and more.

Meet the Beast: Part III




At last the thing is done. Even with the intermezzo post I'm coming in half a week late. It's not the first time I've made an instructional video (I had a small series of beginner level chess videos going a few years back), but as much as I should have really learned by now when I'm planning one of these things it seems I still lack any sense of what a slog I'm getting myself into. On top of that I decided that since my iMovie skills had gathered a few years worth of rust it was a good time to give some other video editing software a go. Not such a great idea as it turned out. The editing process didn't really get rolling until I finally gave up and started over with iMovie.

All this isn't to say I may not try a video episode again but it's certainly not something I'm going to raise any advanced expectations for. If I do try it again it'll just appear here one day unannounced.

As I mentioned before there were other things going on in my photographic world at the same time which I'll talk about next time in the final installment of this series. I might as well make my little confession now though... I've been seeing another camera.

Meet the Beast: Part II

In this second installment of Meet the Beast we're going to have a quick tour of the Mamiya RB67. For serious photographers who like to work with film there's a treasure trove of professional quality medium format equipment on the used market these days at prices that would have seemed like a miracle in the pre-digital age, and of those the Mamiya RB67 represents one of the best values in terms of price and capability.

Early results from not long after I started using the RB67. No coincidence, this was also right about the time my DSLRs became permanently relegated to utility image duty (mostly involving shots of my film cameras.)
The original model, the RB67 Professional was introduced in 1970 and updated versions were released in 1974 with the Pro S model, and finally in 1990 with the Pro SD model which was available new into the early 2000's. There's actually very little difference between them considering 30 plus years the RB was on the market, so if you know how to use one version you won't have any problems with any of the others.

As a medium format camera the RB67 normally uses the same 120 roll film popular in everything these days from Holga to Hasselblad. As the name suggests the RB67 is designed around the 6x7cm format, which means on a roll of 120 film you'll get 10 exposures. The rectangular format means there's almost no cropping required when making prints on standard size papers like 8x10 or 11x14 compared to the square format you get with many similar medium format SLRs such as the Hasselblad, virtually all Twin Lens Reflex cameras, and most of the “toy” cameras that are so popular these days.

The RB67 is a modular system. Six separate components have to come together to create a camera that's ready to use – the camera body, lens, focusing screen, finder, revolving adapter and film back.

The RB67 broken down into its individual components. Clockwise from the top left are the revolving back adapter, camera body, lens, waist level finder and 120 film back. The focus screen is also interchangeable but has been left in place here.


If we start with just the camera body we find there aren't many controls here. From the photographer's position behind the camera we see there's a large lever on the right that might be tempting to think of as a winding lever, but it's functions are limited to raising the reflex mirror and cocking the shutter. The film is wound using a separate lever that's part of the film back. We also have a large wheel on either side which are linked, and these are for focusing. The RB67 is designed to focus by means of bellows built right into the body. There's a release button up front to the lower right which is threaded for a cable release, and that's it for all the controls on the body. The only other detail of note is the accessory shoe, or cold shoe, on the left side.




Lets move on to the lens because this is where most of the controls are. The RB67 uses leaf shutters integral to the lens, so the lens barrel is where you'll find both the shutter and aperture settings. Shutter speeds typically run from 1/400th to 1 second plus a T setting for long exposures. The design of the time exposure mode is one of my little peeves with the RB. When set to T shutter stays opened when it is released which is fine, but instead of the usual method of a second press of the release to end the exposure with the RB you either have to rotate the shutter speed ring off the T setting or start rotating the cocking lever, either of requires you to handle the camera while the shutter is still open, potentially ruining the exposure. Admittedly I can't say I've ever actually lost a shot this way, at least not yet, but why the designers couldn't simply incorporate a superior method that had already been standard leaf shutters for decades is beyond me.

Typical exposure control settings on an RB67 lens. The focus distance scale up front is just a reference for depth of field/hyperfocal distance. Working back from there is the shutter speed ring then the aperture ring. The black switch behind that is the X/M flash sync setting. The red markings near the body are for aligning the breach mount ring when mounting and removing the lens.

Since the shutter is built into the lens this is also where the flash sync terminal is, the standard p.c. socket. As with all leaf shutters flash sync works at all shutter speeds so you can use fill flash outdoors on even the brightest days. I don't know if there's an X/M sync switch on all RB lenses but there is on all the ones I own. Another standard feature on RB lenses, one that's easy to miss, is a little leaver on the lower right that closes the aperture to the stop you have dialed in giving you a quick check on depth of field in the viewfinder.

And finally we come to this little receptacle. At the centre is a standard cable release socket but the collar switch that surrounds it probably needs some explanation. You'll find it can be set to one of two settings that may be labeled “Normal” and “Mirror” or simply “N” and “M”. Setting it to Normal mode, or N, disables the in-lens cable release socket and turns shutter release control over to the release button on the body. Pressing the button or squeezing the cable release attached to it activates the usual exposure sequence, lifting the release mirror, closing the aperture and firing the shutter. In Mirror Up mode, or M, the button on the body just raises the mirror, at which point the shutter can only be fired with a cable release attached to the socket in the lens barrel. This nicely provides photographers with the functional equivalent of a mirror-up lever, but for the unwary there's a hidden trap, and yes I speak from experience here. Being the sort of photographer who normally operates from a tripod and shoots non-moving subjects, normal mode for me is anything but. The lenses are used in mirror mode virtually all the time and I just leave them there. Should I decide to go hand-held or simply don't want the shutter to fire immediately when , there's absolutely nothing to indicate anything is wrong should I forget to turn the switch to normal. I once blew the better part of a roll happily firing away, oblivious to the fact nowhere in that satisfying clunk of the mirror releasing was there a soft click of the shutter. It's the kind of mistake that, in theory, you're only supposed to make once, so lets hope those theorists know their stuff.


The unusual Normal/Mirror Up selector found on the barrel of RB67 lenses. Even experienced photographers will need to acquaint themselves with this peculiar switch before using the RB67 for the first time.

Moving to the other end of the camera, like many medium format SLR's the RB67 uses interchangeable film backs that give photographers two important advantage. First an foremost owning more than one back gives you the ability to switch mid-roll from one film types mid-roll simply by loading each back with a different emulsion. Loading a roll of colour film, therefore, doesn't commit you to finishing the roll before being able to shoot black and white. Second, special purpose backs can be used. The RB67 system included backs for shooting 645 and 6x8cm formats, and two backs that accepted different film formats, 220 and 70mm. While 70mm backs are a rarity, 220 backs were almost as common as the standard 120 version so a word of caution may be in order here. There aren't many 220 films still available, in fact to my knowledge Kodak Portra is the only thing available. If you're in the market for an RB67 it can be easy to overlook the fact that the one you found only comes with a 220 back. On the other hand Portra is a fine film and you can probably find some bargains on 220 backs.

The 120 film back removed. Note that the back has its own winding lever to advance the film, a function the lever on the body does not perform. Backs for 220 and 70mm film are also available as well as 645 and 6x8 format with 120 film.

One final advantage that may be easy to overlook – about half of the things that are likely to fail on a camera like this are in the film transport system. At today's prices just replacing a film back is likely to be much cheaper than having the whole camera repaired, and if you have spares after a failure like this you can just keep shooting.

As with any back that is removable there is a dark slide to keep the film from being exposed when it's not attached to the body. While you could pull this out and leave it as long as the back remains attached it's an easy thing to lose so it's good practice to leave it in until you're ready to make an exposure and return it as soon as you're done. There's no need to worry about accidentally leaving it in or out at the wrong time though as safety mechanisms are there to prevent you from removing the back if the dark slide isn't in, or tripping the shutter when it is in.

So far the RB67 back sounds pretty much like standard fare for a ;medium format SLR of this type, but now we're coming to this camera's defining feature, because the "RB" in RB67 stands for revolving back. Most cameras that shoot rectangular format negatives need to be turned on their side if you want to shoot verticals. That's not much of a problem with 35mm cameras but that presents more of a challenge with heavy medium format SLRs that are more likely to demand the use of a tripod. To shoot verticals most tripod heads require the camera to be dangled off to one side where the camera's extra weight can threaten to tip the whole tripod over. This is one reason so many medium format cameras adopt the square 6x6 format as there is no vertical or horizontal while you're shooting, This keeps the camera's centre of mass over top of the tripod, but making standard rectangular prints requires a good portion of the big gorgeous medium format negatives to be lost to cropping. The RB67 however allows the camera to remain on top of the tripod like a 6x6 camera at all times, making the switch between horizontal and vertical by rotating the back alone. This is done by means of the revolving back adapter, an attachment placed between the body an back. Normally this remains attached to the body as there is rarely a reason to remove it so some users may simply assume this is part of the body. It's and important thing to consider when purchasing an RB67 body alone as sellers might or might not include this component. Remember the back can't be attached to the body without one, even if you're willing to forego the revolving back feature.



At last we come to the finder which, it should be no surprise to learn is interchangeable and many types are available. Most common is the standard waist level finder that is similar just about every other WLF on other medium format cameras. There's no release button required to raise it, you simply pull up on top cover, under which you'll then find a small lever on the right that pops up the focus magnifier. While this is the most basic magnifier it's also the one I prefer, though anyone not accustomed to this type of viewer may find the left/right reversed viewfinder image difficult to adjust to. There is also an eye-level prism finder for those who prefer that fully corrects the view at the cost of some weight, but you're already dealing with 2.5 kg or more worth of camera already, so what's a little more? If you want to go a bit further there are also finders for the RB with metering and other special features. Of note finders are one of the few items made for the RB's sister model the Mamiya RZ67 that can be swapped between the two models. Since its the finder that carries the most visible camera model label it's not unusual to see an RB67 that has "Mamiya RZ67" emblazoned across the front.  

Well, that's all my heart can take this week. In future installments I'll be going into more detail with functional basics such as loading the film, changing lenses and so on, followed by a summary and a few final thoughts. I'm hoping to keep things on a semi-regular weekly schedule but apologies in advance if things are late as I'm expecting to integrate a bit more video as well as all the while I'm bringing a new element into my photographic world which... well, you'll see.

Meet the Beast: Part I

I confess, I've been holding out on you all. That camera I keep talking about, my photographic tool of choice since before this blog began, the Mamiya RB67, has been lurking in the background of much of what I've written in the past, perhaps somewhat mysteriously for those of you not acquainted with its marvels. It occurred to me some time ago that introductions were in order by way of a few episodes devoted to this camera along with all the agony and ecstasy of using one. It's something I could write about any time though, so I figured I'd keep it in reserve for a day I found myself struggling to find a topic. Instead, finding myself once more struggling with the opposite problem of trying to decide which of several topics to tackle next, it occurred to me that if I was waiting for writer's block to occur I might never get to it. And so it was decided I'll wait no longer.


While I have always referred simply to my Mamiya RB67, for the sake of accuracy I should state I have the RB67 Pro S, the penultimate model in the evolutionary sequence of RB67 versions released as updates were introduced. Actually I have two of them. The first one I purchased in September of 2013, complete with lens, 120 back and waist level finder, for under $200. It had a few scrapes and small dings, along with some sort of purple paint stains in the leatherette covering of the finder, but was absolutely functional. Currently undergoing a bit of cosmetic surgery on my basement worktable, it was demoted to a backup role last July when I got my hands on a prettier body via an opportunity purchase. I was really just looking for a good deal online on a second 120 back when I came upon a back, body and waist level finder at a price that was around the high end of what others were asking for a back alone. How could I not?

Back when I was in my twenties the RB67 easily made my short list of cameras I most dreamed to own. In fact if I actually kept such a list officially it probably would have spent more than its share of time at the top. Hasselblads are probably the more typical dream cameras but at the time (though definitely not now) square format was a bit of a turn off for me. The RB67 was really the one and only camera that hit every spot on my checklist - it's a full-fledged SLR that shot big negatives just this side of large format. takes interchangeable lenses backs and finders, shoots rectangular format so no film gets wasted cropping squares (keeping the images square, who does that?) but doesn't require flopping the camera to the side of the tripod to shoot vertical images. The only thing that kept me from owning one at that time was that they were priced into the stratosphere, affordable only to those who could make money with them and the very rich. The thought of owning one was a pipe-dream, almost on par with the Ferrari I wanted. 

Time moves on and many things change while others do not. Ferraris have gone from being the apex symbols of social status so many lust after but can't hope to ever afford to carbon spewing monstrosities so many lust after but can't hope to ever afford. Meanwhile, in that same time period the Mamiya RB67 has gone from being a well engineered, supremely capable photographic instrument considered the exclusive purview of professionals and the most dedicated of wealthy amateurs, to being  a well engineered, supremely capable photographic instrument a schmoe like me can pick up on eBay almost as an afterthought. The cameras haven't changed, it's just the pros who used them now have to satisfy customers for whom even the minute it takes a Polaroid to develop isn't instant enough. Think of that next time you hear laments about how rough it is being a film photographer in the digital age.



So kit-wise at least, my photographic world is pretty rosy, but while I now own the 231year old me's ideal camera plus a spare, now that I'm twice that age (and nearly half again the mass) my thoughts about what constitutes an ideal camera have changed. As I previously hinted at for example, while I once considered it wasteful to shoot square negatives and later crop to a rectangular print, I now often crop rectangular negatives to square images. Yes the 6x7cm negatives are nice when I don't do this but on the whole I think I'd give that up for the benefits of 6x6cm square negatives including 12 rather than 10 exposures per roll, easier storage and the ability to fit one roll of film onto a single 8"x10" contact sheet. That would be so if everything else were equal, but there's something else to consider - providing that extra centimetre's worth of negative costs quite a bit in terms of sheer mass. As I've noted time and again in the past, the Mamiya RB67 is a big heavy camera, and I don't just mean big in the way a medium format camera will be big if you're used to 35mm, Consider this - I put my Nikon FM with a 50mm f/1.4 lens on the kitchen scale and got about 860 grams.  A Hasselblad 500C/M with 80mm lens, 120 back and waist level finder comes in at 1555 grams (source: www.photoethnography.com), a 695 gram penalty to go from 35mm to medium format. On the same scale my RB67, 127mm lens, 120 back and waist level finder comes in at 2596 grams, more than an extra kilogram compared to the Hasselblad, itself a solidly build medium format camera.

The truth is Mamiya designed the RB67 to be a studio camera, luggability was never high on their desired traits list. One thing that was high on that list however, given the importance of dependably in the high volume professional environment for which they were intended, was ruggedness, meaning they're entirely up to the task of outdoor use where conditions are often less than ideal so long as one is prepared to bear the extra load. And this enduring performance, combined with their once near ubiquitous presence in professional studios, mean there is still an ample supply of RB67s on the used market today. This, combined with the limited market appeal they have due to their bulk, make the RB67 the current champion on  the used medium format SLR market in terms of performance/price ratio if you're willing to bear the load.

Granted that can be a pretty big if and for many that alone is a deal breaker. After a largely successful year and a half of ownership it still gives me pause. Even if you leave size and weight issues aside there are things anyone looking at an RB system should take into account in terms of operational and system considerations as well as a few downright quirks. We'll have to leave those for next time however when I'll go into more detail about what it's like to actually operate one of these beasties.
