Ran a roll of GP3 through the Kalloflex yesterday, and there seems to be hope for the old girl yet. A bit early to shed a verdict, but shutter and lens seem to be OKish. I think maybe the faster shutter speeds may be a tad slow. Both lenses seem to be askew in the horizontal plane, ever so slightly. But I can´t see evidence of it on the pictures I´ve taken so far.
How does she handle? Quite well really. I prefer the dials for aperture and shutter speeds on the Rolleiflex, but the levers work OK, and the top read out is more or less equivalent, if slightly less legible than on my 2.8E3. The shutter release is missing the threaded button, making it a bit difficult to trigger gently. Its not your regular threading either, rumour has it its early Leica type (whatever that is). The focusing knob and film advance crank being on the same side is genius, I like it a lot (I knew I would). The screen is OK, not brilliant. The corners are dim in ill-lit situations. The two pictures (link below) were taken in the open with bright sky, but the subject matter was all in the shade, not a optimal situation, and I had to guess at the framing. Not sure how my other TLR´s would have performed there.
Other issues: Its got the best film loading of any 120 camera I´ve tried. Very easy to locate the spools. Its frame spacing is generous, as it starts the first frame earlier on the roll, and the last later than any other 120 camera I´ve tried. Good, unless you are scanning, in which case your (like mine) film holder isn´t wide/long enough. Its got a 75mm lens, not an 80. That´s good, at least if you´ve already got an 80mm TLR. The viewing lens is an f3.0 (taking lens is f3.5), which is good. Its got feet to stand on, saving the bottom leatherette and the combined rear opening and closing mechanism and tripod mount from abuse. On the subject of the back opening and closing mechanism, it is nifty as it pulls the back tight, but combining it with the tripod mount means that the camera needs to be dismounted before changing film. It has no light sealant flocking, as its constructed to be light tight without it. The film counter is up top, next to the finder.
Oh, and as to not get arrested for cross posting, I´ll link to the pictures on the TLR picture´s thread, rather than repost them here:
