Price Paid:
$0.00 Summary: I had an old non-APO, non-DG version of this lens with my Canon EOS 50. When I upgraded to a 350D, I discovered that it was no longer compatible with the camera, generating the dreaded 'Err 99'. I learned that a re-chip might be possible and an e-mail to Sigma was answered within an hour. Alas, my lens was so old that re-chip was not possible (there are several versions of this lens going back over the years), but Sigma did offer me an excellent upgrade price to a new APO, DG version.
Unfortunately, the new lens turned out to be a very poor performer at anything more than 200mm. Shots looked extremely soft, as though a soft-focus filter was used. I thought this was perhaps all I could expect, but comparisons with shots from the old lens showed that it shouldn't be like this.
Another e-mail to Sigma was answered within 24 hours and they agreed to replace the lens with another specimen.
The second lens is very good - well up to my expectations. Don't expect 'L'-series quality, but do expect to get very usable shots that will be adequate for most purposes. In fact, with a sharpening filter in Photo-shop, even crops from small areas and large enlargements are entirely satisfactory. I had the opportunity to try a Canon 75-300 and the Sigma is marginally better at all focal lengths.
The lens is easy to live with - relatively compact and not too heavy. The macro facility is very useful. Strengths: With a good sample, optical quality is excellent for the money. Build quality and feel is good. Weaknesses: - Based on my experience, Sigma still have quality-control issues.
- AF motor is a bit noisy (but OK) Similar Products Used: Canon 75-300 Customer Service: Superb - fast and knowledgable response to all e-mails. I can't fault it.
