Well, my 2 cents. I have a Bronica SQ, a Yashica 124 G and a Rolleiflex T. I am selling the Bronica. Yes, it's a very good system but as I also shoot 4x5, the Bronica needs a tripod outdoor and not so easy to use. I prefer TLR medium camera. I can shoot documentary street view, landscape, portrait and so on. It's for me more on 35mm side. Bronica and Hassy(I had one long ago) are more on large format side for my photgraphy practice. For the lens quality, I suppose that the Planar are better corner cripness than the Tessar formula lens of the Yashica or the Rollei T but I prefer spend my money in film and paper than in overestimated body camera.
