The DC DN 18-50mm F2.8 fast standard zoom will be available from July 2024, offering a 29-80mm equivalent range on Canon’s 1.6x crop APS-C bodies.
This will be followed, later in the year, by the DC DN 10-18mm F2.8 fast wide-angle zoom, giving 16-29mm equivalent coverage.
The company’s four F1.4 primes will follow on from this, giving EOS R100, R50, R10 and R7 users a choice of 16mm, 23mm, 30mm and 56mm lenses that give 26mm, 37mm, 48mm and 90mm equivalent focal lengths.
The lenses, all part of the company’s Contemporary series of mid-priced lenses, are already available for Leica L, Fujifilm X and Sony E mounts, with three of the four primes also available for Nikon Z mount.
With the lenses being made under a license from Canon, Sigma says it’s been able to optimize the AF speed and support features such as image stabilization and lens aberration correction. The news coincides with Tamron also launching a licensed RF-mount APS-C lens.

Our DPREVIEW Tribute:
After nearly 25 years of operation, DPReview closed on 10 April 2023. This difficult decision was part of the annual operating plan review that parent company, Amazon, shared earlier this year.
Over the course of 25 years, DP Review built up a reputation as being one of the most informative places to go for information about that new camera or lens you’re after. DP Review began as an independent reviews site based in the UK in 1998, the brainchild of Philip and Joanna Askey, but it was eventually purchased by Amazon in 2007 and relocated over to Seattle in the USA in 2010.
Cheers DPReview – thanks for the great work and content that guided photographers, videographers and techno junkies the world over!
