+15 AFMA on a New 24mm f/1.4L II - Keep or Return

[conropl]

I set up and tested again this evening. I tested at 50X and 25X the focal length (47" and 23.5"). The results ended up better, but boarder line. The results were:

At 50X focal length test distance I tested it 4 times with the following results:
+11
+12
+9
+10
Avg = 10.5

At 25X focal length test distance I tested it 3 times with the following results:
+10
+14
+11
Avg = 11.7

The 25X was much harder to get set up, and the set up has more effect on the results at that distance (obviously). I got a positive target set up, but kept getting errors. So I went back to the target set up program, and got it set up better. That caused the readings to drop from the 17-20 range (with many errors) to what you see above (avg around +12) and it ran very quickly with no errors. With the two averages at 10.5 and 11.7, it looks like a good place to set it is at +11.



Edit: Now I need to do a little shooting to verify that is where it should be.

After spending the better part of a day testing my lenses with both camera bodies, I am thinking the same thing! The real world is the best test there is.
