AFAIK, Chromatic Aberations will affect results on panchromatic BW film. In effect it lowers resolution even on BW because the image gets blurred...Chromatic aberations would only be a non factor if the film was sensitive only to one wavelength but panchro BW is sensive to all the visible wavelengths...

The scans are pretty large (2x24M) but if you are interested I could send them to you. My impression is that it is very sharp lens. I could not speek about chromatic aberations because I tested them on B&W film. And it is realy cheap here. You could find on for less than $50. Best regards luben
