Different beasties but all rather fun. After a day out with the Leica III, an M3 and a Rolleiflex, I think the Zorki would provide the viewfinder of the M3 (a bit less good) and the lens capability of the III, so it strikes me as a good compromise. But I must have had at least ten people come up to me to chat about the Rolleiflex, and, again, be offered darkroom equipment and a full Mamiya RZ67 kit of lenses. It's one of many reasons why I like funny old cameras - you get to talk a lot!
Now to a lot of developing...
Film amateur with a few rangefinders - Leica III, M2/M3, Werra 3 and Zeiss Super Ikonta 534/16 medium format.
Apart from that have a Rolleiflex 3.5F, the odd Minolta XD7, Hasselblad 500cm, a Topcon Super D and an Intrepid 5x4 large format (not the half of it but I am clearing them out, honest).
I do all my own black and white developing at home.
