next PZ lens test report: Sigma 12-24mm f/4 HSM DG ART
#11
Quote:Actually, I would like see some evidence how it looks like and how big's the impact. 7 samples are not a lot, I was scrolling through 48 pictures (less than an hour? ha! 20 minutes - so really nothing to call it a test) and simply could not see these problems in real world. But I realized I have less high expectations on sharpness as there is so much to be seen on the picture - I simply didn't bother enough to see the structures of leaves close to the lens' ∞ position.

 
 

  Well the third real world resolution graph tells the story, whether you can compromise across the frame for infinity focus, but then you are fiddling either with; use once AF fine tune settings; or MF in LV  not ideal...

 

     ...and all that for F4!
