Although the Canon has an edge over the Sigma with the slightly better photo quality and its wonderful image stabilization, Sigma is a decent enough lens with a hard-to-resist size and a reasonable price.

As a walk-around lens, this design from the Sigma stable scores well over the normal offering of ‘kit’ lenses, giving extended focal length at the long end and improved performance at the wide end. The reduced need for lens changes on the digital SLR’s that it is made for ensures less chance of the dreaded dust getting at the sensor whilst, at the same time, the light weight and compact size will reduce neck ache after long days carrying it around.

The Sigma AF 18-125mm f/3.5-5.6 DC is naturally a compromise but the package is a bit more sound compared to its more ambitious sister lens - the AF 18-200mm f/3.5-6.3 DC. Sigma seems to have followed a quite interesting design approach - ignoring distortions and focus on the rest and this works out pretty well. The lens is very sharp specifically around the wide end of the zoom range but the tele settings aren´t bad either.
