3.0 out of 5 stars Focus-Focus, October 4, 2010
Amazon Verified Purchase( What's this?)
This review is from: Sigma 50-500mm f/4.5-6.3 APO DG OS HSM SLD Ultra Telephoto Zoom Lens for Canon Digital DSLR Camera (Electronics)
Just received the lens. Using with a Cannon EOS XTi.

Pros
- Sturdy feel to the lens
- Impressive focal length range.
- Good picture quality throughout the range (speaking as a non-pro)
- OS pretty good. Taking acceptable quality hand-held shots at full extension in bright sun.

Cons
- Autofocus not working out-of-the-box. Of note that this lens was NOT in the serial number range specified by SIGMA's customer alert.
- Very poor response time on queries to SIGMA's tech service.
- Some (minor) vignetting noticable at longer focal lengths.
- Does not work with my TAMRON teleconverter even though this TC does function with my Cannon lens.
- Heavy

Returning the lense for replacement through AMAZON due to the autofocus issue. Will see how well the next one does.

UPDATE:
Received replacement lense from AMAZON with working autofocus. Took it out today for extensive testing and am well... Read more

5.0 out of 5 stars I am amazed, May 13, 2010

I've had this lens for a few days and am very pleased with it. Given the fact that it's covering such a wide range, I didn't expect it to have very high IQ, yet I am pleasantly surprised. I measured it against my super sharp Nikon 70-200mm f/2.8 VRII with TC-17, both @ 340mm f/6.3 and f/8, and the IQ is about the same on a D300s, even though on a full frame D3s, the 70-200mm + TC-17 is slightly sharper. This is quite remarkable, because 70-200 f/2.8 VRII is one of the best lenses Nikon has ever made, and it can produce better pictures at 100mm than the highly regarded Tokina 100mm macro lens I own, and even when shooting macros, the 70-200 + TC-17 + Canon 500D combo is comparable to the Tokina 100mm.

Image color is great, with vivid contrast. I had a few bird shots at fully extended 500mm and they turned out to be great pictures. CA is minimum too, only slightly visible when fully zoomed in, and no worse than my 70-200+1.7 combo. Focus is fast, even though it has always... Read more

5.0 out of 5 stars Great buy, July 17, 2010
Amazon Verified Purchase( What's this?)
After buying this week I have to say I love the lens. I've only been out three times with it and have taken about 200 frames but have been really impressed with the results. The optical stabiliser really does allow you to shoot hand held at least 4 stops slower than usual and still get sharp images, even at 500mm. There are two optical stability settings, one as a general on setting, and the other for shooting moving subjects.

It is relatively heavy but easily manageable. Today I spent the day shooting an AVP tournament at Hermosa Beach and it was fine.

If you're looking for a large zoom lens to add to your arsenal then I highly recommend this lens. I can see it being a fantastic asset for wildlife photography and I have already enjoyed its huge range capturing sports action such as surfing and volleyball.

I also have sigma's 18-50mm f2.8 lens which I've used for over a year. The construction on both is very solid and the images they produce are... Read more
