Fujifilm X-mount lenses

X mount has been APS-C only since 2012, and that focus is the point: Fujifilm builds lenses for the format instead of scaling down full-frame designs. The results are physically smaller than a full-frame equivalent for the same angle of view and depth of field trade-off.

Read focal lengths in equivalent terms

Everything on X mount is 1.5× — a 35mm behaves like a 53mm, the 56mm f/1.2 like an 84mm. When you are comparing against full-frame lenses, turn on 35mm-equivalent values in the filters so the numbers line up.

The line-up

Fujifilm’s own range is complete: fast primes across the range, f/2.8 zooms, and a compact f/2 prime series (“Fujicrons”) that suits the small bodies. Sigma, Tamron, Viltrox and others now make X-mount lenses, which has brought prices down at the fast-prime end considerably.

Aperture rings

Most XF lenses have a physical aperture ring, which is central to how the cameras handle. The cheaper XC lenses do not — worth knowing before buying on price alone.
