Wide-Angle Prime for Fujifilm X
The Sigma 16mm f/1.4 DC DN Contemporary is an ultra-fast wide-angle prime built for APS-C mirrorless cameras. Its 16mm focal length and f/1.4 maximum aperture suit landscape, astrophotography and indoor architectural work. The lens uses 16 elements in 13 groups including three FLD and two SLD elements. A 67mm filter thread accepts standard accessories.
Stepping Motor AF and Optical Stability
A stepping motor drives autofocus with smooth, quiet operation suited to video and stills. Minimum focus distance is 9.8 inches at 0.1x magnification. Thermally Stable Composite construction preserves optical alignment during temperature swings. The 83.2-degree angle of view remains consistent across the aperture range from f/1.4 to f/16.
Weather-Sealed Build and Handling
Dust- and splash-resistant sealing at the brass bayonet mount protects internals in harsh conditions. The barrel measures 2.8 by 3.6 inches and uses a black finish. No optical stabilisation is built in, so steady handheld technique or in-body stabilisation is required at slower shutter speeds. The fast aperture reduces the need for high ISO in low light.
