Great Entry Level Lens That'll Cover A Lot of Ground

Summary: Great entry level lens for your Canon EOS. Really love the features vs the standard Canon kit lens. This one just feels like a real lens as it's got some heft and it's easy to grab the focus ring (the Canon kit one feels cheap in comparison).
Nice glass - 2.8 constant aperture is a great tool

Summary: I have this mounted on my D200 and D5100, both with great results. As much as I love using my Nikon 35mm 1.8, sometimes you just need that extra versality and range. The 18 - 30mm range is very useful for food shots, closeups, and wide angle shots. I love this glass.
Summary: I bought both the Sigma 18-50mm f/2.8 EX DC HSM Macro Lens for my Nikon D90, and a Tamron 17-50mm f/2.8 lens. I tried the Tamron first, it was ok... Then I tried the Sigma, and WOW! It was a world of difference. First was just the feel of the lens.
Summary: Before purchasing this lens, I tried the comparable Tamron 17-50 f/2.8, but due to two faulty copies that seemed to have some sort of contact issues when used with my Nikon D50, I returned them and tried this Sigma lens.
