Sigma has now officially announced the three rumoured new lenses in their Contemporary lens lineup. As expected, there are two full-frame 17mm f/4 and 50mm f/2 lenses, along with one 23mm f/1.4 APS-C lens. The two full-frame DG DN lenses are part of what Sigma calls its “I series” full-frame lenses with all-metal barrels available in Sony E and Leica L mount.
The 23mm f/1.4 DC DN expands the company’s APS-C lens lineup, adding to the 16mm f/1.4, 30mm f/1.4 and 56mm f/1.4 DC DN Contemporary prime lenses and the 18-50mm f/2.8 DC DN Contemporary zoom lens. Sigma has also announced availability and prices for these lenses coming to Nikon Z Mount.

Sigma 17mm f/4 DG DN Contemporary
The Sigma 17mm f/4 DG DN Contemporary lens provides a low budget, wide-angle lens option for Sony E and Leica L mount shooters. It’s the widest lens in what Sigma calls its “I series” and is extremely light, weighing only 225g (for the L mount version). It’s also quite small, measuring only 48.8mm in length.
Designed specifically for full-frame mirrorless systems, it offers a wide angle of view, with what Sigma describes as “exceptional” optical performance and build quality. The lens design itself, they say, was inspired by the company’s own CINE series lenses.

The Sigma 17mm f/4 DG DN Contemporary lens for full-frame Sony E and Leica L mounts is available to pre-order now for $549 and begins shipping in late April.
Sigma 50mm f/2 DG DN Contemporary
50mm is the classic “standard” focal length. It’s a focal length that resides in the bags of many photographers and filmmakers. This is the fifth I series lens with an f/2 aperture, adding to the 20mm, 24mm, 35mm and 65mm lenses. Again, it’s designed specifically for full-frame cameras and is available in Sony E and L mount flavours.
The metal lens hood, focus ring and aperture, Sigma says, are “knurled for a pleasant tactile experience” with a wide-ish – although perhaps not as wide as many of us have come to expect from 50mm lenses – field of view. The optical design, however, “delivers performance comparable to the 50mm f/1.4 DC DN Art lens”, according to Sigma’s press release, but in a much more compact form. Of course, you do lose a stop of light over the f/1.4, but we should be able to expect great things from the Sigma 50mm f/2 DG DN Contemporary.

Sigma 23mm f/1.4 DC DN Contemporary
The Sigma DC DN Contemporary, being a “DC” lens, is designed for APS-C. It adds to Sigma’s DC DN Contemporary f/1.4 APS-C prime lens lineup, joining the 16mm, 30mm and 56mm. It fits a nice gap in the middle, providing a field of view equivalent to approximately 35mm on a full-frame camera – a common focal length for things like events or street photography.
It offers a full-frame field of view equivalent to that of a 35mm lens, with a wide bright f/1.4 aperture. It’s initially being launched in Sony E and Leica L mount with Fuji X to follow. There’s been no word yet on when or if we’ll see it come for Nikon Z Mount.
