I have both the 90mmA and 75mmA for my M's. As soon as I started using the 75mm for portraits, it replaced the 90 because of the wider depth of field. I use slow (K25, now K64) film and am usually wide open. The 90 just did not have the depth of field and if not focused right on the eye, it was easier to get the eye out of focus. The 75 is also the sharpest portrait lens I have ever used. -Dick
