At a Glance

On Fujifilm X APS-C cameras, the 50 mm focal length corresponds to 75 mm in full-frame terms, so this lens works as a short telephoto prime. The very wide f/1.2 aperture allows a shallow depth of field and short shutter times. It focuses manually with internal focusing, and the filter mount does not rotate. It is aimed at portraits.
