Fuji has announced its new XF 16mm f/1.4 R WR lens. It has two aspherical and two extra-low dispersion elements with a nine blade rounded diaphragm. Fuji claims autofocus speeds with this lens as fast as 0.11 second. It is weather sealed for pairing with the Fuji X-T1.
The aperture ring gives you 1/3 step adjustments between the marked full f/stop points. The lens is comprised of a total of 13 elements in 11 groups and contains Nano GI coatings for reduced ghosting and flare.
The new Fuji XF 16mm f/1.4 R WR lens retails for $999.95 and should ship in May 2015. Check it out here at B&H Photo.
