Sigma 70-200mm f/2.8 has HSM which is the Nikon equivalent of AF-S. However, I heard it is NOT as good as Nikon's AF-S (~80% of the AF-S speed).Francis said:I'm interested in both lenses but I really don't know what's the best choice. Ofcourse, the Nikkor is more expensive but is it worth the extra $250 ?
Pro's and Contra's are more then welcome :roll:
Thanks in advance
