6 out of 10 points and not recommendedBuild quality, HSM focus motor, tripod mount,Not very sharp wide open
There was really one thing only that made me sell the Sigma 70-200 after only two weeks and that was the poor sharpness at f2.8. I feel it was more so at both ends of focusing range. It also displayed a faint halo around brighter objects that were just out of focus.reviewed November 28th, 2006 (purchased for $790)
From f4.0 and upwards everything was much better.
The handling and the quality feel of it was excellent. The sturdy tripod mount was also very good, easy to detach if you needed to.
Maybe I got a bad copy of it, I don't know.
8 out of 10 points and recommendedSmall, cheap, sharp, f1.8Noisy when focussing, front portion of lens moves sideways
This lens is a "must have" in every photographers bag. It's cheap, very light and surprisingly sharp, considering the price.reviewed November 28th, 2006 (purchased for $200)
The f1.8 comes very handy indoors when you don't want to use flash.
The focussing is somewhat noisy but that not too annoying.
The front lens sometimes moves sideways when the lens focusses. You see it as the image in the viewfinder also moves slightly sideways, especially at small focussing movments. It does not seem to effect the sharpness of the image however.
Overall a very good lens.
7 out of 10 points and recommendedPerfect kit lens for a DSLR, AF-SMaybe the closest focussing distance, could be a tad closer
This is a very good "walk about" lens on a DSLR.reviewed November 28th, 2006 (purchased for $300)
Colors and sharpness are as good as can be expected. The only bad thing I can think of in terms of image quality is the barrel distortion at the wide end. You really have to watch where you place the horizon in the frame or take care of it in post processing.
I sometimes miss a closer minimum focussing distance.
I'm very satisfied with this lens.
