Wide-angle lens for Fuji X APS-C

This 12 mm f/2.8 prime covers a 99-degree diagonal angle of view on Micro Four Thirds and an 18 mm equivalent on Fuji APS-C bodies. It targets photographers who want expansive architectural, interior or landscape frames without autofocus. The all-metal barrel and HD anti-reflection coating aim to deliver contrast-rich, colour-accurate images.

Manual installation with clickless aperture

Mounting is a simple bayonet twist onto any Fuji X camera; no electronic contacts mean no firmware updates or focus calibration. The clickless aperture ring and ridged focus ring give smooth, silent control for video, but users unfamiliar with zone focusing may miss focus at wider apertures. The 72 mm filter thread accepts standard circular filters without vignetting.

Consistent sharpness during extended sessions

The 12-element, 10-group design with one super-low dispersion element suppresses chromatic and spherical aberration across the aperture range. Stopped down to f/5.6, depth of field extends from 1.4 feet to infinity, letting landscape shooters work all day without refocusing. The lightweight 13.4 oz construction and metal housing resist thermal drift, maintaining optical alignment during long exposures or time-lapse sequences.

Questions about this item

How can I verify the lens is focusing correctly after mounting it on my Fuji X camera?

Set the aperture ring to f/5.6 and confirm that subjects from 1.4 feet to infinity appear sharp in the viewfinder or on the rear screen.

What accessories are included and which must be purchased separately?

The box contains the lens, front and rear caps, and an ultra-soft nylon pouch with protective lining; filters matching the 72 mm thread are sold separately.

Which focal length should I expect on my APS-C Fuji body — 12 mm or 18 mm?

The lens is a 12 mm optic; on Fuji APS-C sensors it provides an 18 mm equivalent field of view with a 99-degree diagonal angle.
