Announced in January 2017, the XF 50mm F2 R WR was the third lens Fujifilm built to a specific formula: f/2 maximum aperture, compact size, full weather sealing, and fast near-silent autofocus. Reviewers nicknamed the resulting family the "Fujichrons," and with the 23mm and 35mm already in this shop, the 50mm completes the set — wide, standard, and portrait focal lengths all sharing the same size, speed, and build quality.

At 76mm full-frame equivalent, the 50mm is the portrait-length member of the trio, with ten weather-sealing points around the barrel keeping dust and moisture out down to -10°C. It's built for photographers who've already bought into the other two lenses and want the same compact, dependable formula extended to flattering headshot and close-up work.
