This morning, Sigma announced three new lenses: two premium “I” lenses, and one APS-C specific, all in the “C” series. In the “I” series, Sigma gives us a 50mm f/2 and a 17mm f/4, both with the beautiful and compact all-metal build that we’ve come to expect. For APS-C cameras, Sigma now offers a 23mm f/1.4 | C large aperture prime, a focal length that provides the same angle of view as a 35mm lens on a full frame camera.
The “I” series now stands at nine lenses, with a the new 17mm f/4, a 20mm f/2, a 24mm f/2 and 24mm f/3.5, a 35mm f/2, 45mm f/2.8, 50mm f/2, and 65mm f/2, and 90mm f/2.8. As premium lenses, neither of the new lenses is cheap, but they’re not bad considering the cost of most mirrorless lenses these days: the 17mm is priced at $599, and the 50mm at $639, and both will be available later this month.
With the addition of the 23mm f/1.4, Sigma now offers an impressive range of large aperture lenses for APS-C mirrorless cameras (Sony E, L-Mount, and Fuji X Mount). The 23mm joins a 16mm f/1.4, 30mm f/1.4, and 56mm f/1.4, all of which offer excellent optics. The new 23mm is expected to be available in late April for $549.
