During the last two years four lenses has seen the lab with only one within specs - this is disappointing especially for a lens of this price class. If you´re lucky enough to get a decent sample you can expect a very high performance level, especially when stopped down a bit. Distortions, vignetting and CAs are well controlled. The build quality is superb with only the reverse zoom extension as a minor downside. Even so the 24-70mm range is not all that attractive on APS-C DSLRs (39-112mm) - the EF-S 17-55mm f/2.8 USM IS is a better and cheaper bet except regarding build quality. ]]> Sun, 07 Mar 2010 13:49:07 +0100
