This lens meets my needs on my Canon DSLRs better than any other lens of this type. I've owned the Canon 18-200IS since it was released and this new Sigma bests it easily: Better IQ, faster AF and lighter. I used an earlier version of this lens, without the "Macro" appellation on a Sony A55. I preferred that Sigma to the Sony 18-250 -- but this one is more capable, lighter and smaller. All such lenses are a compromise. But this is the best of these "compromises" I've found. Problems: No problems

I have to agree with the other 2 reviewers on this lens. The 883-306 model is for Nikon DX DSLRs. It's a new lens from Sigma. I purchased it a few months ago. So far I'm satisfied.

I have been using this lens for about a month now, and am generally pleased with it, although it does have some limitations and shortcomings, as does any lens.

This is a strong contributor to its value as an all-day walk-around or hiking/backpacking lens. Secondly, it is well-built (for its price), and the controls work ...

I have this lens on a Canon 450D body with battery grip and have found its size and weight well suited to this setup. I tried out the Tamron 18-270, Canon 18-200, Sigma 18-200 and older 18-250. To be quite honest didn't really have an issue with any of them regarding image quality and reach is actually fairly all similar. Didn't like the way the Tamron image jumps when using image stabilisation and the Canon is pretty big. In the end I even bought this lens without trying it in the hope that ...
