The Schneider's get corrections, but most of the Rodenstock's do now also, but as far as I can tell the corrections are standard distortion type adjustments.
What would be nice, for 6700.00 or 8700.00 (price of 35LS and 40-80 respectively) would be that Phase One develop a way to handle diffraction softness as Fuji and now Canon are doing with their lens optimization routines.
Sadly the Fuji Corrections can only be used on in camera jpg, not raw (sure would be nice if C1 or LR figured out a way to use it) and Canon has announced this on the 1DS MKII, not sure how it will in implemented i.e. only on in camera jpgs or raw or both (will C1 and LR be able to use the data?)
With 100MP backs or larger, this type of optimization is what I am hoping to see in the future. I don't see this working with tech lenses are they are pretty dumb, in regards to giving any feedback. And I only hope that it can be added to the modern Schneider/Phase optics via firmware.
These are the small changes that will possible make using such high MP backs a bit easier.
