Jerry,

You're right in saying that your Sigma 75-300 is as sharp as Canon's or
Nikon's 75-300 offerings, but none of them is really sharp! They only score
about 3.1 in Photodo's tests. The better zooms from Canon and Nikon now
score almost as well as prime lenses and manuals for sharpness - around the
4.1 mark (out of 5).
