The Sigma 105mm macro has excellent performance in all light conditions. Although weighty, it is solidly built and is excellently balanced when used with my 600D. Images are crisp and clear. The Optical Stabilisation feature is wonderful and aids admirably in fine macro work.

Dive into a whole new world of photography with an affordable third-party macro lens such as this Sigma model. The Sigma 105mm f/2.8 is available in Canon, Nikon, Sony and Sigma mounts, fitting full-frame and APS-C D-SLRs.

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

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.

I picked up this lens because I shoot a ton of macro work all year round and have been doing so with the 50mm version for over 4 years the only problem i was running into was how close i had to get to my subjects (I.E bugs, insects, ect.

"The image quality of this lens is superb, nicely sharp and great bokeh. Although it's IS is noisy and chromatic aberration is sometimes quite noticeable. But otherwise, it's great."

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.

Love the lens

Relatively lightweight and super accurate. Tried it shooting flowers and small insects. Tack sharp. I own the 120-300 Sigma sports lens and this one is so much easier to handle, especially on the D4.

Consistent Output; Fast / accurate auto-focus; Lightweight; Nice Bokeh; Strong Construction
