canon 300mm is f4-Sigma 70-300mm f/4-5.6 DG APO Macro Telephoto Zoom Lens for Minolta and Sony SLR Cameras Free Shipping

This is an excellent lens – very sharp at all extensions. I particularly like the macro function at 200-300mm – very sharp, very cool, and good stand-off distance in macro. Of couse use a tri-pod in macro. The lens has returned excellent pictures. The lens is fully compatible with my Knoica-Minolta 5D in all its functions. I usually carry just two lenses, this one and the Sigma 18-200mm lens, plus a 1.4x converter, but am thinking about adding the 10-20mm Sigma as well. These are all good lenses, and I certainly do not feel “under-gunned” with this kit. I am very happy with this purchase.
