Is this acceptable?
Mar 14, 2012

Can you please confirm is this sort of corner inconsistency is acceptable?

What worries me is the right side, specifically the bottom right corner.

Lens is a 24-105mm f/4 L IS set to 24mm at f4.

This lens always seemed to be somewhat weaker in the lower right corner. Just got it back from Canon for a tune up. Repair notes say, "Adjusted center, tilt, front and back focus & checked all to factory specs. Product functions were confirmed." Canon tech support said it wasn't worth sending in again since it may come back the same if it met the specs. They also noted that in all lens it may not be exactly a uniform amount of softness in each corner.


Ignore it and move on?


Send it back?
