I was going to bump this thread myself and glad it got bumped for me.
I took the last week to zero in a little more on what I'm looking for, and I really do want to try a medium format camera, particularly a 6x6. I like the idea of big square negatives and prints, even though I know that printing a 6x6 will either waste paper or lead to cropping. But as someone who likes LPs, I gravitate towards this kind of presentation. I also realized that in trying be less conspicuous, I often shoot with my camera by my waist, or hanging from my neck. So something with a waist viewfinder might be just what I'm looking for, so I've been looking into TLRs trying to figure out if they're the right choice for me.
Also, since folder cameras were mentioned in this thread I've dug into those quite a bit. I'm particularly referring to folders from the 50s-60s. It really seems to me like they all are pretty much the same. Some with somewhat better lenses, some with coupled rangefinders, some move the film back instead of the lens to focus, etc., but overall it's pretty much the same camera. The examples of photos that were taken with them aren't bad, but more often than not they're not quite as sharp as I'd want. Also, looking at a lot of them on ebay, most have scratched or fungus-y or hazey lenses. A folder 6x6 would be ideal tho - extremely portable and a big negative, but seems like it would be a hassle to find the right one, or at least necessitate buying a few and keeping the best one. I'm happy to be proven wrong, though!
What are some other possible 6x6 cameras that I may have overlooked? I am not interested in 6x7 cameras despite being a bigger negative yet close enough to 6x6. 10 exposures per roll is not enough for me.
An honorable mention is the Fuji GS645. Also a folder but newer. Seems like the lens is pretty sharp. But the 6x4.6 negative gives me pause. A minor quibble is that when the camera is horizontal it shoots portrait and to shoot landscape it has to be tilted. I'm sure I would get used to it a few a roll or two though. If the Fuji was a 6x6 I'd have one by now.
Lastly, I'm still considering a 35mm rangefinder, and while I found an M mount that could work for me quite well (Bessa R2), I'm realizing that the M lenses are truly a money pit that I'm not sure I want to dive into. LTM lenses are plentiful and cheaper than Ms, and some were even made not that long ago. LTM cameras are also quite affordable (Canon 7..) If I wait for the right deals, I could probably find a decent LTM camera + lens and a medium format camera and still be within my budget. Am I being naive? Are the Leica Ms really that much more unique than everything else, including their predecessor?
