The Sigma 105mm F2.8 EX DG OS HSM Macro ($1,400 list) is a classic macro lens. It can be mounted to full-frame and APS-C cameras alike, although on the latter the field of view will be cropped by a 1.5x factor. It's available for Sigma, Canon, and Nikon cameras .

One of the most recent arrivals on the macro scene, the Sigma 105mm f/2.8 EX DG OS HSM lens may be one of the more pricey options for this focal length, but with its EX designation Sigma promises that both the lens' build and optical qualities befit the demands of the professional user.

The 105mm f/2.8 EX DG OS HSM Macro Lens is Sigma's first macro lens to feature OS (Optical Stabilization) and replaces the Sigma 105mm f/2.8 EX DG Macro Lens . The Sigma 105 OS Macro lens has been in my kit for just over two years and has seen intermittently regular use.

A ruggedly constructed, large-aperture, full-frame, image-stabilized, 1:1 close-up lens, this medium telephoto prime ($970, street) converts up to about 150mm on Sigma's SD1, as well as on most DSLR cameras with APS-C sensors.Its attractions include a nonrotating barrel suitable for lens-mounted...

The Sigma AF 105mm f/2.8 EX DG HSM OS macro is an impressive lens. The resolution is generally very high although the border quality could be a little better at large aperture settings. Typical for macro lenses distortions are a non-issue. Vignetting is only a real problem at f/2.8.

I recommend this lens as an excellent macro, not as a tele. As any younger Sigma it needs service to be adjusted individually to one's camera. Therefore it has to be sent to Sigma together with the camera. They will fine-tune the lens within one week without charge.

Superb macro lens for a very; very attractive price; fast and accurate AF in macro range; optical stabilization

Needs service befor used for the first time; no aperture ring; AF has some weekness when used as normal tele (not as macro

The focal length is long enough to provide some distance between you and the subject without the field of view and higher price of a 200mm optic. The Sigma 105mm f/2.8 has long been regarded as one of the best macro lenses for its price.

It felt so cheap in comparison to my Nikkor lenses. I was trying to avoid spending an extra money to get the Nikon 105 micro and this lens is just not worth it.

Bought this lens to use with my Sony Nex-5 and Ea1 adapter. Right out of the box this lens takes amazing pictures, I found myself chasing the dog around the house getting nose and paw pictures with a lot of detail. Even portraits from 20 feet away take awesome pictures with smooth backgrounds.
