Ultra-wide zoom for APS-C mirrorless

The Sigma 10-18mm F2.8 DC DN is a compact zoom lens built for FUJIFILM X-mount mirrorless cameras with APS-C sensors. It covers a 10 to 18mm focal range, equivalent to 15 to 27mm on a full-frame 35mm format. A constant f/2.8 maximum aperture runs through the entire zoom range. The lens weighs very little and is described as the world's smallest and lightest in its class.

Upgrade from variable-aperture kit zooms

Photographers moving up from slower kit lenses gain a constant f/2.8 aperture that holds exposure steady while zooming. The 7-blade rounded diaphragm produces smooth background blur at f/2.8 and stops down to f/22 for deeper depth of field. Internal focusing keeps the lens length constant and supports smooth, quiet autofocus suited to video work. A minimum focus distance of 4.6 inches and 1:4 magnification at the wide end allow close-up detail shots.

Travel shooters and vloggers wanting fast wide

Dust and splash-resistant construction helps the lens survive outdoor use. The push-on petal hood maintains the compact profile while shielding the front element. Adobe lens correction profiles are available for distortion and vignetting control. Buyers needing a longer telephoto reach or full-frame coverage should look at other lenses. Photographers who require optical image stabilization built into the lens will not find it here.

Questions about this item

What mount and sensor format does the 10-18mm lens require?

The lens uses a FUJIFILM X mount and covers an APS-C image circle, giving a 15-27mm equivalent field of view on that format.

How do I attach the petal hood, and what step is often missed?

Push the hood straight onto the barrel until it clicks; do not twist it, as it is a push-on design rather than a bayonet type.

When should I check or replace the dust and splash seals on the mount?

Inspect the rubber gasket at the lens mount whenever the lens is removed, and replace it if you see cracks or flattening that could let moisture in.
