Sigma's the APO Macro 150mm F2.8 EX DG OS HSM

Sigma's APO Macro 150mm F2.8 EX DG OS HSM is a new macro lens due to ship in January or February. Macro lenses are geared for close-up use, typically with a magnification of 1:1. That means an insect 15mm long in real life will create an image on the camera sensor that's also 15mm long. Telephoto macros are geared for such subjects that can be spooked by the close approach of a camera. The new macro has image stabilization its predecessor lacked and also has a splashproof, dustproof design.
