PMA@CES Trade Show News

January 7, 2014

Sigma today debuted the latest versions of its two most popular lenses, the redesigned and improved 18-200mm f/3.5-6.3 DC Macro OS HSM and 50mm f/1.4 DG HSM lenses.

Sigma's 50mm f/1.4 and long-range 18-200mm lenses have been consistently the independent lensmaker's most popular models, and both got significant upgrades in time for the Photography trade show within CES. Featuring a slick new look and several added features, both lenses have been improved optically and in in close-focusing capabilities.



Sigma 18-200mm f/3.5-6.3 DC Macro OS HSM

The new Sigma long-range zoom has been rebuilt to be smaller and lighter than its predecessor, and now also offers 1:3 near-macro magnification and minimum focusing of 15.4 inches—two inches closer, and a minimum working distance of 14.7 inces.

Sigma has incorprated SLD (Special Low Dispersion) glass elements to reduce chromatic aberration, as well as double-sided aspherical lens elements that reduce linear distortion.


Sigma 50mm f/1.4 DG HSM Art

Sigma's 50mm lens has been revamped and upgraded to join its high-end "Art" lineup of premium lenses. Designed for both full-frame at APS-sensor DSLRs, it is a fast general-use "normal" lens with new SLD glass, optimized AF algorithm for faster focusing, a floating focusing system that reduces lens movement while focusing, and improved quality control.

The revised lens consists of 13 elements in 8 groups—instead of its predecessor's 8 elements in 6 groups, and focuses closer at 15.7 inches.

The two new lenses join the recently-introduced Sigma 24-105mm f/4 DG OS HSM and 18-35mm f/1.8 DC HSM Art lenses, and will be available in Canon, Nikon and Sigma mounts. Pricing has not yet been announced but based on previous pricing it seems Sigma is preparing to continue to go head-to-head against camera manufacturers with high-quality and lower price leneses.
