next PZ lens test report: Canon EF 24-70mm f/4 USM L IS
#14
Markus, thanks for that link. Very interesting. So it seems to happen to all lenses to some degree. I guess the designers assume that any focus shift that occurs as you stop down will be masked by the increased DoF so the photographer won't notice. Still, it's quite an oversight on Canon's part.
