Sigma has announced three new lenses: the 17mm f/4 DG DN, the 23mm f/1.4 DC DN Contemporary and the 50mm f/2 DG DN Contemporary. The 23mm is only suitable for APS-C cameras, while the other two also fit full-frame cameras.
Sigma 17mm f/4 DG DN Contemporary
Sigma recently introduced the 17mm f/4 DG DN Contemporary, an ultra-wide-angle lens specially designed for full-frame mirrorless cameras. This lens weighs just 225 grams (in the L-Mount version) and is 48.8 millimetres long.
The design of this lens was inspired by Sigma's Cine lenses. The 17mm f/4 has a metal body with a textured focus ring, an aperture ring and a lens hood.
The lens comes with both metal magnetic lens caps and clip-on lens caps. Sigma has adjusted the focusing and shortened the overall length of the lens to create a compact body.
The 17mm has a minimum focusing distance of 12 centimetres. The short focusing distance makes it possible to take close-up photos with expansive backgrounds. According to Sigma, this makes the lens ideal for vloggers, hikers and landscape photographers.
Sigma 50mm f/2 DG DN Contemporary
The 50mm f/2 DG GN was specifically designed for full-frame mirrorless cameras. This standard lens is available in Sony E-mount and Leica L-Mount versions. The lens has an AF/MF switch and an aperture ring on its all-metal body.
The maximum aperture of f/2 provides beautiful bokeh, according to Sigma. The optical design delivers performance said to be comparable to the 50mm f/1.4 DG DN Art, but in a more compact form, with a 37% shorter length and 48% lower weight.
Sigma 23mm f/1.4 DC DN Contemporary
The Sigma 23mm f/1.4 is a fast wide-angle lens specially designed for APS-C mirrorless cameras. The lens has a field of view equivalent to 35mm on full-frame.
Sigma says this lens was designed for optimal mobility when used with APS-C mirrorless cameras. The lens has a compact and lightweight body, weighing 340 grams and measuring 76.9 millimetres in length.
