you have been enthusiastic about the Schneider Digitar lenses, and now suggest in "Whats New" today (March 4) that the Rodenstock HR lenses (Apo-Sironar digital HR?) might be even better. Am I reading to much into this? Do you only mean that the Rodenstock HR s are as more or less as good as as one can currently get, on a par with the Schneider Digitar's? Do you have any idea how these two new "digital large format lens systems" compare?
I note that both these lens systems are assessed for MTF at up to 60lp/mm, which corresponds roughly to the resolution of a Bayer array sensor with 5 micron pixel spacing, fitting your prediction of 5 microns as roughly the lower limit on pixel size for formats this large.
Also, Rodenstock lists 37x49mm (61mm image circle) as the target recommended sensor size, even though the spec. sheets and MTF graphs describe coverage up to 70mm image circle diameter. That 70mm is a perfect fir for 645 film format, but 37x49 matches the current largest sensors.
Is this a hint that Rodenstock has been assured by Kodak and Dalsa that they do not plan to go beyond their current largest sensor sizes, so that lens designers can now target that 61mm image circle diameter? Or am I again reading too much into this?
