Sigma 10 mm f/2.8 EX DC FISHEYE HSM
1. Introduction
At the end of the last year the Sigma company announced the launch of two very interesting instruments – the Sigma 4.5 mm f/2.8 EX DC CIRCULAR FISHEYE HSM and the Sigma 10 mm f/2.8 EX DC FISHEYE HSM. The former is a typical circular “fisheye” for small sensors. What’s important, it’s already fallen prey of our test procedures and here you can find the results.
The second lens – the Sigma 10 mm /f2.8 EX DC FISHEYE HSM – is a diagonal “fisheye” which gives 180 degrees angle of view on 1.5x multiplier detectors. When you use it on the Canon detector, we get 167 degrees angle of view, on Sigma reflex cameras we get “only” 153 degrees.

The Sigma 2.8/10 mm is not as unique as the 4.5 mm model. From quite a long time we’ve got the diagonal Nikkor 2.8/10.5 mm or the Olympus 3.5/8 mm and also, on the Canon and Nikon mount, the Tokina 10-17 mm. It won’t change the fact that the new Sigma can interest a lot of users because it’s a lot cheaper than the Nikkor and the Olympus and faster than the Tokina and as a standard prime, could have a better picture quality.
Small wonder, though, that immediately after the launch in Poland we contacted the K-Consult company to borrow the lens for our tests. The results are presented in the next chapters.
