Right now my lightest and most compact medium format camera is a Rolleicord. It's around a pound and a half and while small by medium format standards, it is not necessarily svelte. Enter stage left, the medium format folder. The promise is a medium format camera that can be fit into a jeans pocket. But for me, to make it worth the hassle of carrying a medium format camera, the image quality must be good. It must surpass not only my Rolleicord but also my autofocus Nikon 35mm setup (in other words, the best 35mm has to offer).
So are there any cameras out there that can meet my requirements? It should be lighter than 850 grams, fit into a pocket and match or surpass the image quality of a Rolleicord. Bonus points if it has a rangefinder. Is it possible?
