Sigma has announced a new APS-C lens to its popular Art portfolio, plus a new mirrorless lens in its Contemporary family.
We don't yet know when they'll be available or for how much, but here's what we do know.
The new Sigma 50-100 F1.8 offers a 75-150mm, 35mm equivalent focal length. It maintains a constant f/1.8 aperture throughout the zoom range. The new Art lens incorporates a new Hyper Sonic Motor which Sigma says is 30 percent slimmer than previous motors to drive fast, precise autofocusing.
It has both inner focusing and zoom, a tripod socket and accepts 82mm filters. It has a minimum focusing distance of 37.4 inches and will be sold in Canon, Nikon and Sigma mounts.
Mirrorless camera owners will also get some fast glass. The 30mm f/1.4 features an AF stepping motor for improved autofocusing during video. It’s built using one aspherical element and one double-sided aspherical element–a combination that Sigma claims helps deliver image quality “comparable to the Art line.”
The lens has a minimum focusing distance of 11.8 inches and accepts 52mm filters. It will be sold in Sony E and Micro Four Thirds mounts.
