ownership:I own this lens
compared to:Minolta 100-300
Sigma 70-300 APO / APO DG
price paid:
Macro capability (1:2)
negative:build, poor AF gear
slow AF, hunts in low light
comment:It is cheap but unreliable, the focus gear is a poor construction and left me in the most unfortunate situation.
Sharpness with open aperture is acceptable in the lower half of the range but in geneal it needs to be stopped down to f8 (mid range) to f11 (300mm) to get reasonable sharpness at the borders.
The Minolta 100-300 mm is better in every aspect, except that it starts at 100 mm.
The Macro capability is a nice and useful addition but only available at 300 mm where the IQ is not great. The APO (DG) revisions are visibly better and more useful in this regard.
