I make 16x20 and 20x24 prints, so need 56x70 mm negative. For studio portrait ,... I have Linhof BY with RapidRolex (56x72mm) + Rodenstocks. I used to use (I can already state it) mamiya rz proII which is ... But i realized such a camera has non-forgiving problems (say absolutely unreliable camera). I am looking for a camera to replace RZ ProII with 50mm-ULD-F4.5, Macro 140mm, and 90mm lenses. 6x6 must be croped to 45x56 so it is much smaller than 56x72 which I like. I will use it in field, say events, weddings, and location portraits. Thinking between Hassy and Rolley 6008i or 6001. Can Zeiss lenses like 50 mm distagon and 100 mm planar accomodate for loss in format size so I can make the same photograph quality, with film speed twice less, as I had with RZ mamiya. Pentax 67 I think will take me no where due to bad lenses. Also I wold like that my new friend free me me from technical problems like slide in mamiya. My new camera will be used for professional work, so no sorry. Would like to hear words from McBlane also. What you woud do in my place.
