Sigma lenses for Fujifilm

6 lenses from Sigma for Fujifilm. 0 are Fujifilm’s own and 6 come from 1 other brands, among them Sigma. Focal lengths run from 10 mm to 56 mm, 4 are primes and 2 are zooms. The fastest opens at f/1.4.

Sigma brings its Contemporary line to X mount: six lenses, every one of them autofocus. The two zooms are the reason most people look here. The 18-50mm f/2.8 holds a constant aperture across a standard range in a body far smaller than the usual f/2.8 standard zoom, and the 10-18mm f/2.8 does the same at 15–27mm equivalent.

The four primes — 16mm, 23mm, 30mm and 56mm, all f/1.4 — line up almost eaxctly against the Fujinon f/1.4 primes at 24mm, 35mm, 45mm and 85mm equivalent. That makes this the brand where the native-versus-third-party comparison is most direct, because the specifications match rather than approximate.
