SIGMA has released three new lenses in their Contemporary lineup of lenses: the 17mm F/4 DG DN, 50mm F/2 DG DN and 23mm F/1.4 DC DN. All lenses are available in two versions for either L-mount or Sony E-mount mirrorless cameras. So let’s take a closer look at this trio of lenses!
After the recent announcement of the development of lenses for Nikon Z-Mount APS-C mirrorless cameras – now available for pre-order – SIGMA is already back with three lenses as part of its Contemporary lineup. First is the 23mm F/1.4 DC DN, compatible with APS-C mirrorless cameras. Next are the SIGMA 17mm F/4 DG DN and 50mm F/2 DG DN, which are likewise Contemporary lenses but are also part of the I Series lineup and cover Full Frame image sensors.
Let’s start with the I Series lenses that are part of the SIGMA Contemporary lineup: the 17mm F/4 DG and the 50mm F/2 DG DN. SIGMA I Series lenses are made entirely out of metal, including the lens cap and lens hood, they cover Full Frame image sensors and are available in either Sony E-Mount or L-Mount.
The 17mm F/4 DG DN weighs 225g/7.9oz for a length of 4.8cm/1.9″. The 50mm F/2 DG DN is slightly heavier at 350g/12.3oz for a length of 6.8cm/2.7″.
You’ll find a dedicated aperture ring and a knurled manual focus ring on the lenses. There is a physical AF/MF switch if you want to deactivate the fast internal stepping motor, and the lenses are dust and splash-resistant.
The lens design of the SIGMA 17mm F/4 DG DN consists of 9 elements in 8 groups, including two Special Low Dispersion (SLD) and three Aspherical elements. The aspherical lenses and SLD glass element should help suppress most lens aberrations, including astigmatism and field curvature, which cannot be corrected in-camera.
The rounded 7-blade diaphragm is typical for a wide-angle prime and should provide a smooth and subtle bokeh. Also, the minimum focusing distance is only 12cm/4.8″, with a front filter diameter of 55mm. Just so you know, if you use a front filter, you can’t use the included metal lens cap anymore, and you’ll need to switch to the included plastic one.
The lens design of the SIGMA 50mm F/2 DG DN is a bit more complex, with 11 elements in 9 groups. In addition, there are three aspherical lenses and one SLD glass element to eliminate aberrations and flare.
The rounded 9-blade diaphragm should provide a pleasing bokeh when shooting portraits. The minimum focusing distance is 45cm/17.7″. The 50mm lens is 58mm and shares the same filter/lens cap issue as the 17mm, as do all SIGMA I Series lenses.
The SIGMA 23mm F/1.4 DC DN covers APS-C image sensors and is the full frame equivalent of a 35mm lens. This lens is available in either Sony E-Mount or L-Mount.
With a length of 7.7cm/3″ and a weight of 340g/12oz, it won’t take up much space inside your camera bag and might be an excellent all-around daily prime lens.
On the inside, you’ll find a high-speed stepping motor for fast AF performance.
The lens design of the SIGMA 23mm F/1.4 DC DN consists of 13 elements in 10 groups with three SLD and two aspherical lens elements.
The diaphragm has nine rounded blades, and the minimum focusing distance is 25cm/9.8″. The front filter diameter is 52mm.
All lenses are available to pre-order now and will start shipping at the end of this month. The SIGMA 17mm F/4 DG DN retails for $599/€521, the 50mm F/2 DG DN is $639/€588, and the 23mm F/1.4 DC DN is $549/€427.
