Love that Bronica...
Love that Bronica...
Thanks, znapschatz; and interesting commentary on your impressions! I've had a Bronica RF645 since early this year, with all three lenses. It's still my most favored camera, taking over this roll from my long-loved Minolta CLE. These cameras have similarities in character. Compact, well-made, auto exposure, interchangeable lenses, flash integration, inconspicuous, with crisp contrasty RF spot.
The camera you saw, with the 135mm framelines, had not been modified for the 100mm lens, yet oddly was mismatched with a 100mm! The mod (free from Bronica) involving swapping out the frameline mask. My newer camera came with the 100mm frame to match the 100mm f/4.5 lens.
Robert White in the UK had a different solution, buying up all the surplused 135mm lenses and offering a precision matching service for customers. The main issue seems to be that the manufacturing tolerances in some cameras and lenses stacked up unfavorably to produce inaccurate focus wide open at short distances. Some were fine.
My 100mm lens has focus markings down to 5.9 feet, but can focus closer in an unmarked region to indicate less certainty of accurate focus. I might have preferred the Robert White solution... This whole focus issue has tarnished the reputation of the camera, perhaps unfairly, but Bronica made an error.
Others too have questioned the vertical finder, and I'm puzzled. Half-frame 35's also had vertical format "naturally" and I don't recall complaints then, and the 645 format has been around for many more decades. Anyway, I'm just as happy with this upright position as with the horizontal framing of my Pentax 67. Each must be turned for the other orientation, so what difference does it make?

I have used several square-format cameras, and recognize the advantage of never having to choose orientation, and while I'm glad of the choice for those who do, somehow I've never really liked the square.
I came to the Bronica from a Fuji GS645S, the "Wide 60", not the folder. I had bought a dud, and was told it was infeasible to repair. I did later get it fixed, though. The Fuji is much lighter in weight, but the meter isn't as good, its shutter has a loud "clack" sound, and worst it's rangefinder spot is one of those dim and fuzzy ones. On the upside, its framelines shrink for closer distance as well as shift for parallax.
The Bronica has a lovely Leica-quality RF, and the shutter is nearly silent. That odd little buzzz-click sound at the end of the exposure is the electronic shutter recocking for the next shot.
If I had a gripe, it would be the exposure compensation dial on the back of the camera. Unlike a couple other controls, it has no lock button... convenient for fast use but unfortunately subject to inadvertent change.
And, yeah, I'd gripe about the lack of 45mm framelines. I'm sure they could have done it! Actually, I've never used the external 45mm viewer, instead framing the wide-angle lens with the entire finder area outside the 65mm framelines.
What I like about both these 645's is that they're inconspicuous (if you can ignore that Fuji CLACK), and smaller/lighter than the big auto/motorized 35mm SLRs. Yet they offer excellent optics and relatively huge negatives. With its metal frame, the Bronica is heavier but faster and easier to use.
I've mostly been using the wider lenses, but here's one from the 100mm...
