To maintain high optical performance from infinity to close-up 1: 1 (life-size) macro photos without accessories, the new Sigma 50mm f2.8 EX incorporates a "floating" element focusing system. Designed as a quick-focusing macro lens the AF speed of 50mm, f2.8 EX Macro is 1.4 times faster than previous 50mm f2.8 macros. It features a non-rotating front lens group, which makes it easier to work with polarizing filters and has a focus limiter. The Sigma 50mm f/2.8 EX Macro lens also features the new deluxe EX external finish. A handy screw type metal sunshade makes it easier to rotate a polarizing filter.

This Sigma is a nice everyday lens. It produces sharp & contrasty images, excellent build quality, fast AF, and smooth zooming. It's light and compact, making it easier to carry the camera around all day.

The 67mm filter thread is nice because the filter is cheaper than the newer 72mm macro (not really true macro) version. The AF sound is more audible than Canon USM, but far from noticeable with ambient noise, unless you are in a really quiet environment.

For the price, this is an excellent lens.
