Canon EF 28-105mm f/3.5-4.5 II USM for EOS

This review is for the USM version. If you're seeing this review on a listing for the 28-105mm non-USM lens then see my other reviews (sorry the seller has selected the wrong lens for their listing).

This is the bigger brother of the 24-85mm and has Ring-USM, better optics and better construction.

On a crop body (smaller that 35mm sensor, ie the 300D,350D,400D, or the 10D,20D etc), this isn't very wide angle (28mm is the FOV equivalent to a 45mm) but the 105mm end is very handy.

On a crop body, 28mm is the equivalent to 45mm, so if you want wide angle you may be better off looking at the 24-85mm version (as 24mm is the equivalent to 38mm).
Also watch out which version the seller is actually selling, as Canon have made several lenses with this focal length.

Summary: It's a good walkabout lens, and an excellent upgrade from the kit lens supplied with most Canon DSLR bodies. But watch out if you want wide angle on a crop body.
