While the Sigma 150mm f/2.8 lens has been out for a good while we decided to take a closer look at one of the most interesting pro-oriented products in their lineup. One of the key selling points in this lens is built-in optical image stabilization ("OS" in Sigma-speak) to aid in achieving...

I love shooting pictures of insects, birds and flowers. Getting use to being further from my subject has taken some time for me with this Macro. It definitely has it's advantages like not spooking little creatures. The crispness of the pictures/subject taken with this lens are utterly amazing.

Great lens, a little heavy, focuses well with my 5DmkII. VERY shallow depth of field. Sometimes is difficult to have the theme complete in focus withoutd using flash and f/ 16. Its not the macro lens for all day, thats the 50mm, but can be valuable for live insects and animals, snakes for example.

There aren't many third-party manufacturer products which truly stand out from the crowd. However, Sigma's 150mm f/2.8 EX DG HSM APO macro lens was clearly one of them. Sigma has just released its successor featuring Sigma's OS (Optical Image Stabilizer).

This is the second lens i have bought,the first one made a squeaking noise,and could not focus there seems to be a problem with the tripod mount bracket if you tighten it just a little bit more it will not focus properly. and this is happening to this one!!

Durable; Great Features; Great Picture Quality; Simple Controls

Bulky

If you want more working distance to photograph insects buy this lens. Photo included.

This f2.8 lens is one of a number of Sigma macro lenses and sits between the 105mm and 180mm units. It is image stabilised and focuses internally so the lens barrel does not extend. It has full frame coverage and on an APS sensor camera has a focal length equivalent of 225mm.
