SIGMA has made an entry into the market of autofocus lenses for the RF platform with six new APS-C RF Autofocus lenses.
Canon’s new third-party license has opened up opportunities for new lens designs, and Sigma’s upcoming lenses are expected to appeal to photographers and videographers alike.
The six APS-C autofocus lenses will be part of Sigma’s Contemporary line, with four prime lenses and two zooms. Let’s take a closer look at each one.

Firstly, the SIGMA 16mm F1.4 DC DN | Contemporary, built with 16 lens elements including three FLD glass elements is designed for low-light performance, minimal optical aberrations, and sharp resolution. It has a maximum magnification ratio of 1:9.9, and in-camera image stabilization, and continuous autofocus support for video from quiet and precise stepper motors.

Secondly, the SIGMA 23mm F1.4 DC DN | Contemporary has 13 elements in 10 groups, including 3 SLD glass elements and 2 aspherical lens elements.
It has a full-frame equivalent angle of view of 35mm, and a maximum magnification ratio of 1:7.3. The lens is also designed to minimize lens flare and ghosting through lens element coatings and dust resistance.

Moving on to Sigma’s 56mm F1.4 DC DN autofocus lens. This lens sports an effective, full-frame focal length of around 50 mm.
The lens is designed with 9 lens elements and one aspherical lens element, coated with Sigma’s Super Multi-Layer Coating to reduce lens flare and ghosting.
It also has a 9-bladed aperture diaphragm and a shallow depth of field for a round and smooth bokeh, compatible with in-camera image correction provided by Canon’s mirrorless cameras that support the feature.

Rounding out the Contemporary prime lens collection is the SIGMA 30mm F1.4 DC DN. It has 10 elements including one SLD glass element that provides for axial color aberration while remaining compact and lightweight.
The lens has the same 9-bladed aperture for a round and smooth bokeh and a maximum magnification rate of 1:7.4. The lens also supports face recognition and eye autofocus functions.
For zooms, SIGMA has added a pair that covers the entire wide-angle focal length of 10-50mm. The SIGMA 10-18mm F2.8 DC DN | Contemporary has an effective 35mm equivalent focal range of 15-27mm and a maximum magnification rate of 1:4.
The lens is designed with 13 elements including three aspherical lens elements, three full low dispersion lens elements, and a solitary special low dispersion element. With Sigma’s special super multi-layer lens coatings, the lens can produce high-resolution images while combating lens aberration, flaring, and ghosting.

Lastly, there’s the SIGMA 18-50mm F2.8 DC DN | Contemporary. This wide-angle zoom comes packed with 13 lens elements, including three high-precision glass-molded aspherical elements and one SLD lens element, with support for in-camera aberration correction.
The SIGMA 18-50mm F2.8 DC DN | Contemporary is expected to ship by July 2024, while the remaining 5 lenses are expected by Fall.
There is no information available about pricing at this time, but the company does state that the lenses will also be available for Leica L, Fujifilm X, Sony E, Nikon Z, and micro four-thirds mounts.
