Comments about Sigma Sigma 300-800mm f/5.6 EX DG APO IF HSM Digital AutoFocus Telephoto Zoom Lens for Canon EOS Cameras:
I was looking at this lens for about 1 year and finally got it. I always test the sharpness of the lens and this lens at 800mm is sharp. It is heavy, but if you have a good heavy tripod, you will get some great sharp images. A great lens but not a carry around type lens.
