Berg,
It was not my intention to bash the 90mm Makro, indeed it is one of the best, and INHO better (sharper with digital) than the older 120mm Makro. Sorry, wrong choice of words.
I was trying to say that there was NO CA when I used the 90 mm lens on the ALPA without shifts or on my 6008AF, and I noticed a minor cast with shifts. I cannot say that it was lens' fault of a problem with the eMotion 75 (33 mpx). I had no CA (at least visible ) with my eMotion 22 even with extreme movements, and some other users on this forum said that 33 mpx. dalsa sensors are more prone to CA.
All the casts were very easily dealt with the Brunbaer DNG tool (white shots through the opaque plate) and corrected automatically in the software. I am sure that Sinar CaptureShop and Leaf Software can do the same kind of corrections. BTW for focusing Rollei lenses on ALPAs I use a small tethering program Stephan Hess (Brumbaer) very kindly sent to me. It is enough to get a correct position of the lens, evaluate the exposure and then switch to shooting to the CF card. Very easy.

Thank you very much Yevgeny
I am a not happy to hear that you found CA on the macro 90mm, its meant to be one of the best
lenses in the range?
best
