Sigma has announced 17mm F4 DG DN and 50mm F2 DG DN mid-priced ‘I Series’ prime lenses for L-mount and Sony E mount, as additions to the ‘Contemporary’ range, along with an APS-C 24mm prime.
The 17mm F4 DN DG is a relatively compact wide-angle prime for full-frame cameras. It’s 64mm wide and 49mm long and consists of nine elements in eight groups, including two special low dispersion (SLD) elements and three aspherical elements. It can focus as close as 12cm to give a 1:3.6x magnification ratio.
Despite its metal construction, the lens weighs just 225g. Filter size is 55mm.
The 50mm F2 DG DN is considerably larger at 70mm wide and 68mm long, and weighs 350g. It has eleven elements in nine groups, with a single SLD element and three aspherics. Filter size is 58mm.
Both lenses come with magnetic metal lens caps and pinch-style plastic lens caps, as well as bayonet-style metal hoods.
The new lenses will be available late April. No local pricing as yet but US pricing is US$599 for the 17mm F4 and US$639 for the 50mm F2.
Sigma also continues to support APS-C format with a new 23mm F1.4 DC DN for Sony E, Leica L and Fujifilm X mounts. It delivers a 35mm-equivalent field of view. (It’s worth noting there is no version launched for M43 of the Canon M-mount.)
Sigma’s Contemporary DC DN range now includes options at 16mm, 23mm, 30mm and 56mm F1.4 primes (24, 35, 45 and 85mm at 35mm equivalent) for APS-C shooters of Sony, L-mount and Fujifilm cameras.
The 23mm F1.4 DC DN is 66mm wide and 77mm long and takes 52mm filters. It has a 13 element/10 group design, including three Super-Low Dispersion (SLD) elements and two aspherical elements. It weighs 340g.
Available late April, US pricing is $549.
