Overview

Description by Sigma:

This large aperture f/2.8 lens has an angle of view of 114 degrees. 

It is equipped with SLD and aspherical lenses for high image quality; 2 elements of aspherical lenses and 2 elements of SLD glass are being used to compensate aberrations and vignetting. 

It has a minimum focusing distance of 18cm (7.1 in.), and a maximum magnification ratio of 1:4.5. 

The HSM models for Sigma, Nikon and Canon mounts provide ultra quiet high-speed autofocusing as well as full-time manual focus override. An inner focus system provides high performance and convenience. The lens also incorporates a built-in lens hood and a gelatin filter holder behind the rear lens element.

Reviews

"Overall, Twinkles is a real pleasure to shoot with. On my 20D, it focuses silently, very fast, and right on the money literally every time. I don't think I've had a single case of missed AF that wasn't obviously attributable to user error. I've shot with it in lighting conditions from bright sunlight to night streetscapes and poorly lit interiors. The major shootability issue is related to flare: Twinkles produces flare spots like there's no tomorrow, so I often found myself shading the lens with my hand, which was sometimes left in the frame and had to be cropped (or cloned) out. The exposed objective lens is a real dust and fingerprint magnet, too.
