Decided to fit the tiny little 28 to the M9 this week.
Since I'd never used this lens on the M9 before, I took out the lens coding kit and created the code on the LTM->M adapter for 11804. Then I checked the M9 lens codes table that someone had posted (I think created by Sean Reid and someone else) and found the recommendation there for using 11604.
That led me to making a very fast set of three test images .. open blue sky at the same settings (ISO 160 @ f/8 @ 1/160 s) .. one with the auto lens code setting, one with the 11604 lens setting, and one with no-code setting.
Results are interesting. The 11804 setting produces the best blue of the three, the others are a bit cyan, and the least amount of corner edge fall off, but all three show some magenta shifting on the left.
Using the 11804 image as a calibration test target, CornerFix cleared up the magenta shifting on all three nicely.
Interesting results. I'll have to experiment more and use a gray card for more accurate evaluation, of course. Funny thing is that when I'm not taking a photo of a clear blue sky, the color shift is much less pronounced and in most cases almost unnoticeable. .
