Such lenses have very large apertures that let users shoot clear photos in low-light situations, with very shallow depths of field. At 4. 07 inches long and 1. 86 pounds, the XF50mmF1. 0 R WR lens isn’t tiny, but it’s not huge, either, considering the 12 lens elements in nine groups.
The only other autofocus f/1. 0 lens in recent memory is Canon’s full-frame EF 50mm f/1. 0 L SLR lens, which was discontinued in 2000 but is still worth thousands on the used market. The XF50mmf/1. 0 R WR makes a strong statement for Fujifilm’s lens design team, but its not out of reach like the $8,000 Z-Noct.
Fujifilm has unveiled the world’s fastest autofocus lens, the XF50mmf1. 0 R WR designed for its APS-C sensor X-series mirrorless cameras.
By comparison, Fujifilm’s 56mm f/1. 2 lens weighs . 9 pounds and is three inches long, while the full-frame Z-Noct is 6 inches and weighs 4. 4 pounds.
