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.
