Thank you all for your feedback. True, DOF is smaller but lenses are slower: My 80/2.8 on 6x6 focussed at 5meters has a DOF of 1.1 meters. My FA50/1.4 on APS-C focussed at 5 meters has a DOF of 0.6 meter So does it really influences so much ?
Whatever, I had a look at a Mamiya RB fitted with a 55mm and Waist level finder. It has a 3D look as well, though less than my C330. Maybe those Mamiya lenses or the finder... I love that look :) 2011/1/7 Matthew Hunt <[email protected]>: > On Fri, Jan 7, 2011 at 8:54 AM, Thibouille <[email protected]> wrote: > >> Is that the lens? The finder?
