A Contemporary Trio from Sigma for Sony E-Mount and L-Mount

Today Sigma announces 3 new lenses for Sony E-mount and L-Mount – the 17mm F4 DG DN | C, the 50mm F2 DG DN | C, and the APS-C format 23mm F1.4 DC DN | C.

Sigma’s new 17mm and 50mm are part of the “I Series” lenses, and feature an all metal construction with cine-lens like build cues, while the 23mm is the 4th APS-C prime from Sigma for Sony E-Mount and L-Mount. 

Sigma 17mm F4 DG DN | Contemporary – I Series

The super compact 17mm is the widest “I Series” lens from sigma and expands the line-ups range now from 17-90mm across 9 lenses. The lens comes in at just 225 grams and is a little under 2 inches long without the hood. A perfect lens for those that like to travel light and shoot wide, the lens has a knurled focus and aperture ring, and comes with a choice of standard snap-on lens cap, as well as a magnetic lens cap. The close focus abilities of this lens (12cm) allow for some creative close-up photographs with a wide look to them. With a fast stepping motor driving the autofocus, the lens is also perfect for vloggers and one handed use without making the camera setup too heavy. 

The lens construction consists of 9 elements in 8 groups with 2 SLD elements and 3 aspherical elements, a 7 blade rounded aperture, and a 55mm filter thread. The mount features a rubber gasket for weather resistance and optical coatings to minimize flare and ghosting. As with all Sigma lenses, the lens is made in Japan. 

Sigma 50mm F2 DG DN | Contemporary – I Series

A classic “standard” portrait length lens, the Sigma 50mm is the 5th “I Series” lens with a f/2 aperture and features the same solid design as the 17mm and other “I-Series” lenses. For those looking for a tactile experience when using the lens, the 50mm F2 provides just that, with its metal body/lens hood, knurled rings, and small size. With a weight of just over 12oz and a length of 2.8 inches, the 50mm F2 is 37% shorter and 48% lighter than the Sigma 50mm f/1.4 DG DN Art. Those are significant savings for only losing 1-stop of light, and the optical design delivers results pretty comparably to the Art lens. 

Like the 17mm, the 50mm is driven by a stepping motor for fast and reliable autofocus performance. The optical construction of the lens is 11 elements in 9 groups, 1 SLD and 3 aspherical elements. For smooth bokeh, the lens has 9 rounded aperture blades, and a minimum focusing distance of 17.8 inches. 

Sigma 23mm F1.4 DC DN | Contemporary

For APS-C shooters, the 23mm is the 4th lens in Sigma’s DC DN Prime lineup, fitting in nicely between the 16mm, 30mm. and 56mm. With the lens initially launching for Sony E-Mount and L-Mount, a Fujifilm X-Mount version will be available later in 2023. Providing a ~35mm full frame equivalent field of view, the Sigma 23mm is a great multipurpose lens, and with its fast aperture, allows it be versatile even in lower light situations.  From everyday photography, to landscapes, to journalism, the 23mm is a compact and optically solid option for APS-C users. 

The lens comes in right around 3 inches long and weighs 340 grams. Using the same stepping motor as the two I-Series lenses it was announced with, the autofocus is fast and accurate for photographers, and silent for videographers. The minimum focusing distance is just under 10 inches, and the lens features a 9 blade rounded aperture, just like the 50mm, for pleasant bokeh effects. For landscape photographers, the lens has a 52mm filter thread, and is coated for excellent flare/ghosting resistance.
