Super-telephoto lenses usually come with compromises. The best telephoto lenses are also the heaviest and most expensive, and while you can get cheaper consumer level zooms, they typically don’t have the same durability or optical quality. But the new Sigma 500mm F5.6 DG DN OS | Sports aims to fix this by combining professional performance with a more affordable price tag.
The Sigma 500mm F5.6 DG DN OS | Sports is a mirrorless-only lens which will come in L-Mount and Sony E-Mount versions. Sports and wildlife fans may already be familiar with the older Sigma 500mm F4 DG OS HSM | Sports lens for DSLRs, and while this new mirrorless alternative is one f-stop slower at f/5.6 vs f/4, it’s also massively smaller, lighter and cheaper.
Despite this, Sigma appears to have thrown all its optical and design expertise at this new super-telephoto prime. It uses “exclusive” low-dispersion glass elements, including convex low-dispersion elements towards the front of the lens barrel to help keep chromatic and axial aberrations to a minimum, and “Refractive” lenses control ghosting and flare in backlit situations in an optical configuration consisting of 20 elements in 14 groups.
Sigma has designed this lens to appeal to both enthusiasts and professionals, especially those shooting fast moving subjects like birds in flight. The Sigma 500mm F5.6 DG DN OS uses a high-speed HLA linear motor for “fast, accurate and near silent” autofocus. The lens also incorporates optical stabilization using Sigma’s latest OS2 algorithm for 5 stops of compensation with a regular Mode 1 and a Mode 2 for panning shots.
Other physical features include a detachable tripod mount, a focus limiter switch, custom mode switch and a de-clickable aperture ring. The Sigma 500mm F5.6 DG DN OS is also compatible with Sigma’s TC-1411 (1.4x) and TC-2011 (2.0x) teleconverters for extended focal lengths up to 1000mm,
The Sigma 500mm F5.6 DG DN OS is made using TSC (Thermally Stable Composite) materials and magnesium and incorporates weather sealing and a water and oil resistant coating on the front element.
