Sigma 120-300mm F2.8 EX APO IF HSM AutoFocus Telephoto Zoom Lens For Canon EOS Cameras

Rating:
Summary: A fantastic fast lens with a large zoom capability.
Review: A huge lens. Requires a monopod at least to make it steady. If you hand hold like I have tried, you'd better get used to body building! The 105mm? front thread makes filters crazy expensive. I got the UV for protection and bought a circular polarizer (ouch) also. I've used this lens for outdoor sports and find the zoom to be immensely more handy than the primes so that i don't have to reposition myself constantly. The sharpness is pretty impressive for a non-Canon lens and the HSM focus is very fast. Using AI Servo with the 20D makes taking sports a breeze. Using this with the Canon 20D also makes this the equivalent of a 192-480 f/2.8 zoom which is amazing.

A great deal but if you don't need that extra range from 200-300mm, then just get the canon 70-200 f/2.8 IS which is an amazingly fantastic lens. and you'll save a few bucks also. BUT if you need that extra 200-300 and you dont' feel like throwing out the crazy $ required for a canon 100-400 or other canon lenses that cover the 200-300 spectrum (and are NOT consumer lenses-ie. mostly junk), then get the sigma which for under $2K is a fantastic lens for the price.
