For tight head shots and head-and-shoulders portraiture, there are lenses that are all too ready to stand up and be counted. Best of breed 135mm primes include the Canon RF 135mm f/1.8L IS USM, Nikon Z 135mm f/1.8 S, and Sony FE 135mm f/1.8 G Master. I gave 5-star ratings and Gold awards to the latter two of these, and only knocked half a star off the rating for the sophisticated yet comparatively cut-price Viltrox AF 135mm f/1.8 LAB. All of these lenses are absolutely fabulous, but they all have two things in common – a focal length of 135mm and an aperture rating of f/1.8. There’s nothing wrong with that, but could things be even better?
Sigma has a long history of pushing the boat out and creating some really off-the-wall lenses, and the company shows no signs of slowing down. Recent world-firsts include the Sigma 300-600mm f/4 DG OS Sports and the Sigma 200mm f/2 DG OS Sports (at least for mirrorless cameras), to name but a couple.
