Must have for Macro photos. This is some of the best glass available for macro 1:1 photos on the market at any price range and the fact that it cost around 1K makes it a deal.

Absolutely the best Macro I have ever used, pictures jump out at you with vivid colours and textures you'll never see with the normal human eye

150mm is a pretty unique focal length for a macro lens, coming up close to the very heavy and very expensive 180mm L from canon. having a longer focal length is a double edge sword, as it can give you shallower depth of field, but also can make it harder to get all your subject in focus.

Bought this for my wife who loved her Non IS sigma version but really wanted the IS for hand holding since she didnt want to be carrying the tripod...

Solid; well constructed; clean bokeh; even better with IS

Sizeable and reasonably heavy; 2 different lens shades can get confusing

So you're seriously thinking about this lens ... what else might be useful to know? Here are some ideas for extending the effectiveness of this remarkable lens and getting the best out of macro lenses in general (part 1 here ) With the Sigma 150mm f/2.8 EX DG IF HSM on a D300 body and Nikon R1C1...

This is the perfect focal length for timid subjects like insects, allowing a practical working distance that minimises the risk of frightening them away. Despite its focal length and fast maximum aperture, the lens has quite a compact design.

The Sigma 150mm f/2.8 EX DG HSM Macro Lens delivers excellent image quality in a relatively long focal length (for a macro lens) at a very reasonable price . The image quality a lens is capable of presenting to the camera's sensor is typically the biggest concern I have with a lens.
