Comments about Sigma Sigma 135-400mm f/4.5-5.6 DG APO Aspherical AutoFocus Telephoto Zoom Lens with Hood & Case for Canon EOS Cameras:
This is (for me) a VERY sharp lens. I've used Nikons best and the Canons "L" series lenses and this ranks up there with them. While it would be nice if there wasn't any lens creep, for the price, focus, durability, and quality, you cant beat it. There are a handful of complaints about their versions of the lens, but if you get a good one, you cant go wrong. If you dont like your version, get it fixed or replaced and you wont be sorry.
