I've made a small research and from what I understand, the values of Image Circles of Rodenstock HR lenses given at Alpa website and rodenstock-photo website are very 'conservative' and real/practical image circles of these HR lenses are bigger. Can anyone confirm that / tell me what I'd be able to squeeze out of Digaron-S HR 28mm, 40mm and 70mm lenses in terms of image circle coverage when shooting film? In other words, assuming I'd be shooting Alpa 12 TC camera, so without any movements, what is the biggest film size I can use? And in particular, assuming one would be shooting film, is it possible to pull off a 6x9 frame with 40mm / 70mm Rodie HR lenses?
And one more question- which "digital" lenses would be suitable for 6x9cm film capture as well in terms of image circle size? Prefereblay Rodenstock HR, from what I understand they are regarded as better lenses overall than Schneiders.
Thanks!
