Sigma 10-18mm f/2.8 DC DN | Contemporary (Fujifilm X-Mount)

The Ultimate Ultra-Wide for Vloggers and Travelers

If you shoot on a Fujifilm APS-C camera like the X-T5, X-H2, or X-S20, finding a wide-angle lens that is bright, sharp, and actually lightweight can be a challenge. Enter the Sigma 10-18mm f/2.8 DC DN | Contemporary—the world's smallest and lightest ultra-wide f/2.8 zoom lens for APS-C mirrorless cameras.

Providing a full-frame equivalent field of view of 15-27mm, this lens is wide enough to capture sweeping landscapes, tight real estate interiors, and perfectly framed vlogs at arm's length. Combining a fast f/2.8 aperture with an incredibly tiny footprint, it is the ultimate "leave it on the camera" ultra-wide for hybrid creators in the Fuji ecosystem.

Why You'll Love This Lens

• Invisibly Light: The Fujifilm X-mount version is the lightest of the lineup, weighing just 250g (8.8 oz) and measuring barely 2.5 inches long. It completely redefines portability for an f/2.8 zoom, balancing perfectly on lightweight Fuji bodies without exhausting your arm during long vlogging sessions or causing motor strain on a compact gimbal.

• Constant f/2.8 Aperture: Unlike typical kit lenses that get darker as you zoom, this lens stays at a bright f/2.8 all the way through the zoom range. This allows you to keep your ISO low for clean indoor video and creates surprisingly pleasant background separation when focusing close to your subject.

• Unique Push-On Petal Hood: To keep the footprint as small as possible, Sigma completely redesigned the lens hood mechanism. Instead of a traditional bayonet twist, it features a newly developed spring-and-lever system that pushes on securely and quickly, saving precious space in your camera bag.

• Vlog-Optimized Autofocus: Powered by a quiet, high-speed stepping motor, it delivers rapid and highly precise autofocus tracking. Crucially for videographers, Sigma designed the optics to minimize focus breathing, meaning your framing won't shift distractingly when the focus racks from the background to your face.

• Extreme Close-Up Capability: At the 10mm wide end, you can focus as close as 11.6cm (4.6 inches) from the sensor. This allows you to create dramatic, highly stylized perspectives with a sweeping, out-of-focus background.
