This lens is Sigma 18-50mm f/2.8 EX DC Macro HSM (Built-in motor) (Nikon fit). Mounted with Nikon D80(also has motor). I tested AF speed. In my opinion, I think it's quite slow. What do you thing? Or I get the bad copy? Thanks for your comment. UPDATE : The happy ending www.youtube.com

*Now available* An upgrade to its predecessor, the 18-50mm F2.8-4.5 DC OS HSM is a lens dedicated to digital SLR cameras with APS-C size image sensors offering a large aperture and Sigmas Optical Stabilization. Once again, Sigma has also engineered the built-in OS function, an anti-shake system, for Sony and Pentax mount allowing the photographer to see a stabilized image in the viewfinder. The combination of the large aperture of F2.8 and anti-shake function makes capturing exceptional photos in low light achievable, and the wide angle is well suited for indoor photography. Two SLD (Special Low Dispersion) glass elements and three Aspherical lenses provide excellent correction for all types of aberrations. The Super Multi-Layer Coating reduces flare and ghosting. Designed with inner focusing and inner zooming systems, high image quality is assured throughout the entire zoom range. The overall length of the lens does not change during focusing and zooming ensuring convenient handling. This lens has a minimum focusing distance of 11.8 inches (30cm) throughout the entire zoom range and a maximum magnification ratio of 1:4.1. The incorporation of HSM (Hyper Sonic Motor) ensures a quiet and high speed auto focus.

This is a video testing the Sigma 18-50mm f2.8 EX DC lens on the Canon 600D/T3i. This was filmed in poor to low light and the footage is straight from the camera with no grading or colour correction. Quite a cool lens, much better then the kit lens even though you lose a zoom length of 5mm I think the fixed aperture of f2.8 more then makes up for that. Also when you pull focus the end of the lens stays static where as on the Canon kit lens the end rotates. This lens is considerably heavier then the kit lens. I would rate this lens 9/10.
Some photographs i took with my new Sigma 17-50 f2.8 lens. Zoomed up to +- 105 % to give you a close look at how sharp all the details are. Remember these photos have been compressed three times before you view them; once when converting RAW to JPEG, once rendering an .MP4 (H264) video with...
