A well made and thought out macro lens with enough focal length to enable skittish insect photography without putting them to flight. Quiet and faster focusing with the ability to restrict the focusing to the area you are working in improves the experience also. Good balance on the excellent tripod collar makes for easy tripod work. Good, but not outstanding picture quality. A nice lens.

For the price, it is not hard to justify buying the Sigma 150mm f/2.8 EX DG HSM Macro Lens over the also excellent Canon EF 100mm f/2.8 USM Macro Lens. The Canon has much better AF, less light fall-off and costs less - until you add the optional lens hood and tripod collar. The Sigma's longer focal length provides some extra working distance and a narrower angle of view (less background that is more diffusely blurred).
