This is a wonderful macro lens that rivals the Nikon and Canon big guns for sharpness. Great value and the built in optical stabilizer is perfect when using it as a portrait lens, which it also excels at.

Super sharp!! Great lens all around. It does have a clunking sound when the lens is off the camera body but this is normal and does not mean the OS is broken.

I've been shooting this lens for a few weeks and have pretty much left it on my second body (I was using a 50-200 or a 70-300 on it). Most people use it for macro but I really got it to extend the range of my Sigma 17-50 f/2.8 OS and it fills in beautifully for most things.

Great bokeh; fast lens; sharp

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 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.

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.

The Sigma lenses are becoming my favorite. That is a hard statement consider I am team Nikon everything. I had a Nikon macro and it worked okay, but the motor broke and I returned it. This gem was on sale ($400 off!) so I gave it a go. I am so glad I did! The clarity and Bokeh is amazing.

First, thanks to Adorama for the excellent and fast service to replace the defective lens.The replacement lens arrived as scheduled.The lens is heavy. It produces sharp images if it get at the correct focus as the autofocus was some kind like hunting.
