Rodenstock has been asleep at the wheel for years it seems, but I would think that if the tech camera lens business still means something for them they may be somehow in the prcess of designing better wides able to limit downsides with the CMOS sensors?
Disagree. The best lenses in MF digital right now are Rodenstock ones.
Nearly everybody agrees the 90mm HRSW is the finest MF lens out there, bar none. Large image circle (100mm, good for a 4 way stitch) and sharp beyond anything you have seen in MF. I hear good things about the latest design wide ones, though they are not of interest to me.
Remember production numbers for MF are very low, and if an Otus for FF Canon/Nikon is $4500, then for the reduced production quantity for MF - larger element size, smaller numbers and you're talking about a $20,000 lens... and for what? - the 90mm is astonishingly good, even the old HR series (60f4, 100f4, 35f4, etc) are still excellent, (but no movements).
I'd like to see Zeiss come back into MF too, but it's simply not going to happen as production numbers are too low. The only hope is that the new Fuji takes off, and others (Sony, Phase) come into the MF mirrorless, and dramatically increase the market place for such lenses.
