I just treated myself to a new 24-70mm f/2.8 L... which for some reason does not perform as it should. Even when stopped down to 4.0 or greater, sharpness is not satisfying without some serious sharpening in Lightroom.


Compared to my other L's (e.g. 70-200 f/2.8 IS), sharpness is lousy...So far I only have checked the lens on my trusty 20d bodys using AF.





Did anyone have similar problems with the 24-70 and did you send the lens back to canon for warranty/exchange or similar?





Cheers,


Andre





A few tests...
