Let’s not be coy about this, I’m a big fan of Fujifilm cameras and the X-Mount specifically. Since I picked up my X-Pro, shooting with Fujifilm cameras has been a blast. But one of the biggest gripes I’ve had with the system in the past was the lack of third-party lenses with autofocusing capabilities. Well, the tide is definitely turning on that front with Sigma’s most recent announcement that their Contemporary DG DN primes are coming to the X-Mount system.

16mm, 30mm, 56mm F1.4 Primes
While the recent announcement will immediately bring three fast primes to the X-mount the truth is that these lenses have been available for some time on different camera mounts – namely Micro Four-Thirds, Sony’s E-mount, Canon’s EF-M mount, and most recently on the L-mount. That’s not necessarily a bad thing as the lenses have performed quite well on those systems and should translate well to Fuji’s APS-C cameras.
The lenses will take advantage of a number of camera-specific features including AF detection, Continuous AF, and focus speed optimization. The lenses will also take advantage of in-camera aberration correction and the lenses themselves will have a rubber-sealed mount construction that will allow you to shoot in weather (a plus for those of us that think a snowy/rainy day is the perfect day to shoot).
Additionally, if you own any of the previous iterations of Sigma’s Fast Prime Trio (my name not theirs) and have recently switched systems, Sigma offers a mount conversion service that will allow you to keep your glass and take advantage of the native mount features of the newly announced lenses.

Looking to the Future
Personally, this has been a long time coming as I’ve long lamented the ability to use AF lenses other than the ones that Fujifilm had to offer. While the native lens selection is expansive it can also be pretty expensive – especially for an F1.4 lens. Opening up the system to third-party manufacturers means that fans of the X-Mount system will have even more options for great glass and fewer compromises. As for Sigma, they’re not stopping with the Fast Prime Trio – also announced are plans to bring the recently available 18-50mm F2.8 DC DN Contemporary to the X-mount by the end of the year.
The lens trio will be available for the X-Mount starting in April 2022 and pricing ranges from around $265 (30mm F1.4) up to $400 (56mm F1.4). You can get more info on the trio here.
