Sigma 18-125mm F3.5-5.6 DC

4882618_125dc_1_
Review Date: Dec 28, 2006 Recommend? | Price paid: $200.00

Pros: wide zoom range, cheap, lightweight
Cons:
poor image quality, focusing problems, slow

I bought this lens, because it was testet at photozone.de pretty good, and I thought could replace the Kit of my 350D without any lack of quality. I have the SIGMA 18-125 now since about 8 months and shot more than 1000 photos with the lens.

Of course the zoom range seems to be very useful. Wide Angel to medium tele (200mm equivalent), at a price of about 200 , with a quality that should be as good as the quality of the Canon 18 - 55 II kit lens.

The build quality of the lens seems to be really much higher than the one from the Canon kit lens. The manual focus ring ist much better to grab, and there are no parts shakeing. But the lens zooms itself out or in when holding in an angel of more than 70 down or up, that's very disturbing.

So far the good sides of the lens. The quality of the images aren't really good. Especially at the wide end I hd pretty much of barrel distortion, and strong vignetting that is disturbing even on normal small prints. The resolution is good in the center and semi-good at the corners from 18 - 60 mm, above the center remains semi-good but the corners really got pretty bad.
CAs I had always with this lens, and that more than with any lens I owend before.

But the biggest problem for me is that the lens often doesn't find the correct focus, even in light daylight I have pics with front- or backfocus. Shooting series in the "AI SERVO" mode is impossible, I almost don't get any sharp image from that series.

Sorry for that lens, it look really good and I expected a lot from it, but it was a big dissapiontment.

Here are some example shots I just took today:
