Sigma announces two more prime lenses for Canon cameras, but I'm still waiting for full-frame third-party glass

The first wide-angle primes land for Canon's APS-C cameras. When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works. Sigma has launched two fast-aperture prime lenses for Canon mirrorless cameras; the 16mm F1.4 DC DN Contemporary and 23mm F1.4 DC DN Contemporary. They join four other Sigma lenses available for the Canon RF mount, all of which are designed for crop sensor (APS-C) models such as the Canon EOS R7 and Canon EOS R100.

The new lenses increase the total number of Sigma 'RF-S' lenses to six in all, and are the first wide-aperture primes; the 16mm lens has an equivalent 24mm focal length, while the 23mm lens has a 35mm equivalent focal length. Both lenses offer popular focal lengths with fast f/1.4 apertures, ideal for working in low light and for creating shallow depth of field portraits – I personally relied on a 35mm f/1.4 Sigma lens for a number of years while doing documentary photography in East Africa.

Sigma has set the price of the 16mm F1.4 lens at $439 / £389 / $617, while the 24mm F1.4 costs $549 / £479 /AU$817. These are reasonable prices when you consider the proven optical performance from Sigma Contemporary lenses, plus the fact that Canon equivalents would likely be pricier – should Canon ever launch them.

Canon kept its lens mount closed to third-party lenses makers longer than rival brands, a move that frustrated some fans, especially given how few lenses Canon has launched for its APS-C cameras. That all changed in April 2024 when Canon gave the key to its RF-mount door to Sigma and Tamron, and we have six existing Sigma lenses rolled out for the RF-mount already.
