Showing 1-10 of 21
Good Price, NOT sharp, Macro feature is weak
25 April 2012
Summary: I wanted to like this lens so badly because I own another Sigma lens (10-20mm wide angle) and I love it. Unfortunately this one fell short. I read all the reviews-good and bad-and decided to take a chance. Unfortunately the 'bad' reviews were dead on in my opinion. I purchased this lens over the Canon version specifically because of the macro feature.
Excerpt: Got this for a secondary lens for my wife after a field mishap with her old one. Very poor performance. Slow focus soft images.Not good for any kind of action. Would probably be ok for stationary shots.Ended up getting a Canon lens.
Pros: Easily Interchangeable, Lightweight
Cons: Blurry Focus, Lens Creep, Macro not sharp, Slow Focus
Shoddy construction and performance make this two thumbs down from me

Summary: I have heard so many good things about Sigma's 17-70mm street zoom from other photographers, that I stupidly trusted the reviews on this lens. I needed it for a shoot of a President Obama speech, and ended up being unable to use it when I received it. Not only was it difficult to get it to focus at the best of times, whether handheld or on a sturdy Manfrotto tripod, with shake reduction on or off, it also got completely stuck in macro mode--I could NOT get the toggle...
Summary: This range just does not seem to have a really good lens on the market right now and hopefully one of the companies who makes K mount lenses will do something about the problem. If I had it to do again I would buy a fixed lens at 300 or 400 in a manual focus lens.
Summary: For a cheap lense (compared to Nikon or Canon), we have to accept some scrifice. Relative speaking, it is a good outdoor lense since we always stop down to F 8 at least. Having used it mainly for my Canon EOS 10D in the last 2 years, I am quite happy with it. When I compared this lense with my friend's Canon 70-300 IS, at F11, the difference is quite small in case of sharpness.
Pros: Liight weight and feel quite sturdy
Cons: focus quite slow with low contrast subject and quite noisy when focusing
Summary: The display image has aperture ring and my decision to go for this product was largely motivated by this feature. However, the lens I received does not have the aperture ring at all. This is a big negative for all photography enthusiasts.
