Sigma has just announced a mirrorless version of the herculean 60-600mm f/4.5-6.3 DG DN OS Sports Lens. Compatible with full-frame E and L-Mount cameras, it is the first interchangeable lens to bring 10x magnification to the mirrorless form factor. Like its popular DSLR predecessor, the new zoom delivers maximum versatility for sports and wildlife photographers looking for an all-in-one super tele.
To achieve such impressive reach, the 60-600mm relies on a complex optical design consisting of 27 elements arranged in 19 groups. This includes two F Low Dispersion (FLD) and three Super Low Dispersion (SLD) elements to temper color fringing, aberrations, and other distortions. A Super Multi-Layer Coating has also been applied to combat flare and ghosting. For close-ups, it has a maximum magnification ratio of 1:2.4 at 200mm.
