A fast telephoto prime for FUJIFILM X-mount mirrorless cameras, the XF 90mm f/2 R LM WR is a 137mm-equivalent lens featuring a bright f/2 maximum aperture for low-light performance and extensive control over focus placement. The optical design incorporates three extra-low dispersion elements to minimize chromatic aberrations and color fringing and a Super EBC coating has been applied to control flare and ghosting for increased contrast and color fidelity.
