Visited the Sigma booth at PMA today and played with the SD10 digital SLR, the new 24-60mm f/2.8 EX DG lens, and what might be a sweet sleeper of a sports lens - the 120-300 f/2.8 HSM lens. This was my first really close look at the 120-300mm lens and I got to try it out on an EOS 3. The HSM autofocus really is fast, the lens feels solid, and the range is awesome for some of the landscape mountain bike photos I shoot.
Verdict? I'm buyin' it!
