This is a good lens for photographing insects and other invertebrates, Excellent working distance for macro work. Autofocus works very well as dose the OS ,I use a mono pod for most of my photos, I found the lens a little heavy but it has a good balance on my Nikon camera.

Truly an incredible lens at a good price point. It replaced both my 105 and 200mm micro lenses with the added benefit of image stabilization. Used mainly manual focus but when activated, the auto focus worked well. Took over 500 pictures with this lens alone on our wildflower mountain expedition.

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

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

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.

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.

Needs microadjustment but when you are finished with that cumbersome work you are really rewarded. With that manual fovus and silent HSM you can film very nice macros. You need steady hands or tripod for best results. Kills my Canon 100 mm 2.8 - so I sold it. Best bang for the buck!

Sharp; Supergood feel when MF

No OS

SLRgear Review May 2, 2012 by Andrew Alexander Sigma announced the 150mm ?'/2.8 EX DG OS HSM APO at the 2010 Photokina, though it wasn't until later in 2011 that the lenses actually started shipping.
