Leica 90mm APO f/2 calibration issues on M9

[johnnygoesdigital]

I've recently been using a Leica-M 90mm APO f/2, on my M9, however, the lens does not seem to achieve tack sharp focus even at f/11 and fast speeds. I used a magnifier to be sure the focus patch was correct, but still can't find it to be acceptable. In a portrait for example, one side of the model will be "soft" sharp, while the other side not at all. What's interesting, is that along the same plane in a small area, the focus is sometimes sharp then falls out and then back in again. Also, the contrast is very muted and washed. This is a rental, but thought this lens was the the most stellar performer. I understand that cameras sometimes need to be calibrated, but it seems this is not the case with areas in and out of sharpness.

Sounds like the lens needs to be serviced...

You have a bad lens that requires service. The 90/2 is not an unusual challenge to get sharp images with an M9. Simple test throw a hat out on some grass ..focus on the hat . Should immediately tell you if its a focus issue ..if you can t find a plane of sharpness ...then the lens is damaged .
