I have five TLRs, various Minolta Autocords and Yashica Mats. My first love was the Autocord, which unfortunately had to be put aside after the focus lever no longer focused. So I started buying other cheap TLRs to replace it (since I was a student and had limited funds) but after a few months or so the shutter would not work, or only sometimes work, or the film advance would die, or whatever. And I just bought another, rather than pay to have them fixed. However, this past summer I bit the bullet and finally got my first love overhauled and fixed since none of the replacements have felt as good, or had as nice a lens as the original. That was four months ago...and now it's died (the little shutter speed lever has broken, shutter speeds sound completely off). So now I'm in the position (provided I get enough teaching hours in the coming semester) of having to replace that camera (so it can join the four others on my shelf collecting dust) and I'm debating what to do and would like some advice. I love the square and want to stick with it -- if I want to go bigger or rectangular I have my Crown Graphic for that. I also love the portability of the TLR -- it's not any heavier than my manual nikons which means it gets used a lot. That being said, I've had my eye on the Bronica SQ Ai system since it seems to offer what I want at a price I can afford. BUT...I'm worried about weight (especially for travel) and handholding abilities (I do use a tripod on occasion but I really am a more spontaneous shooter than that for the most part) -- I'm not able to rent a system here, or even look at one, to check it out. What I'd really like some advice on, is whether I should invest in another TLR system (a good Rollei or Mamiya), or go for the Bronica. I'd like to hear from users who made the switch from a TLR to SLR system and their thoughts on the advantages and disadvantages of doing so.
