Yeah that was my first thought after posting that. SDM works now.
Here are the pictures from the test. They are all labeled with the focal length and apeture.
50mm: everything looks good
28mm: not as much back focus as 16mm but still apparent
21mm: not as much back focus as 16mm but still apparent
16mm: lots of back foucs from 5.6 down
So there it is...
What do you guys think :\
Is it the general consensus that this lens works well on the K20d?
