"Sports and Wildlife photographers would love this lens. The best thing is, I did not care about the weight after a while. It was fun to shoot with.

Is a 300/2.8 lens (regardless of the manufacturer) a viable nature photography lens? Again, this is something only the individual photographer can determine. While the 300mm focal length may be just barely adequate in many cases, the f/2.8 aperture is a godsend in low light. With the addition of their matched 1.4X and 2X teleconverters, the Sigma 300/2.8 HSM EX also serves as a 420/4 and 600/5.6 autofocus lens, capable of delivering excellent results. For other than the song bird photographer, this may be all that is ever needed."
