Sigma's First Digital ONLY Macro Lens

"Unbeatable for the price and quality"

This is a fantastic walk-about and general purpose lens for cropped sensor Digital SLRs -certainly for value for money, it's unbeatable. It does not feel cheap, the build quality is good, it feels sturdy and it comes with a zoom lock, which prevents the zoom sliding out when walking about.

Superb value for money; great image quality; good construction; high maximum aperture

Noticable barrel distortion at 17mm
