Sigma 180mm f/2.8 EX DG OS HSM Lens Review
13 December 2012
Excerpt: This telephoto macro lens from Sigma is the first 180mm macro lens capable of life size magnification with a fast f/2.8 maximum aperture. This lens also sports optical image stabilisation and silent HSM focusing, with full time manual override.
Pros: Superb sharpness, even at maximum aperture, Effective optical stabilisation, Good build quality, Fast focusing, especially for a macro lens, Hood extender supplied for use on APS-C cameras
Cons: CA towards the edges of the frame may become an issue for some applications, Price may be a little higher than many might expect for a lens from a third party manufacturer
