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.

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.

Price / Quality

Wanted to get a macro lens to complete my equipment setup, after looking around the Sigma looked like one of the best to try. The 105mm focal length means to don't have to get too close to anything which might be scared off e.g. insects and so far the lens has produced excellent results.

Very Loud Os

This is a serious bit of kit it's just stunning the only bad point is that it's so heavy this is a lens for Charles atlas !!!. Now I've got the bad point out of the way I took the lens and my Nikon d5600 out in the midday sticking it into hedges to get bug shots I will admit I had to bump the iso up...

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.

Although it's not the cheapest of lenses, the Sigma 105mm macro proved to be worth its price-tag. The HyperSonic Motor provided the fastest and most accurate AF and the Optical Stabilizer was invaluable for handheld shots, but where the lens really excelled was in the image quality it produced.

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.

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.

"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."
