Graflex RB: Back Modification by
Ed Wenn, on Flickr
My original text from Flickr: "Here she is. The knackered, but mostly functional Graflex RB 5x4 that bought on evilBay for a mere £40. Sure it looks like a pile of crap, but they usually go for around $600, so I'll forgo the 'mint condition' styling given the $500+ price difference. She's big though. Pentax Program-A 35mm SLR for size comparison."
My main issue with the beast is that the mirror and glass are so old and degraded that it's impossible to compose a shot other than with a wide open aperture. Unfortunately, the rails are pretty shot too, so if (for instance) the camera's on a tripod and pointing either up or down at its subject, you compose, focus etc. and then go to put the film in, only to find that the lens has shifted forwards or backwards just enough to require a re-focus. Grr! Also, when the RB is wide open the DOF is almost non-existent, so it take FOREVER to compose and focus. It once took me 45 minutes to take a really ordinary photo of a vase of flowers.
Most of you will have put up with my complaints over the years of how I have 20 seconds a day to devote to photography etc., so this camera doesn't exactly fit into that timetable.
All of that said however, there's no escaping the fact that an LF SLR is an awesome concept and I guess that's why these babies usually costs a few hundred dollars/pounds. I was lucky to get mine for much less than that and a better person than I would have dedicated some time to fixing it up. As you can see from the 2nd photo of the camera, I had to modify the back a bit in order to use the 545 Pola back, but that should have been the start of the refurb, not the finish.
In the end I bought an LF Field Camera and haven't used the RB at all since then. I've been meaning to sell it on, but never got round to it.
