Fuji issued the new lens roadmap and includes the lenses that have been already “rumored” before. The 16mm f/1.4 and 90mm f/2.0.
The mentioned super telezoom will be a 120-400mm lens according to Fujirumors.
And here is the official Fuji press text about the new roadmap:
“FUJIFILM Corporation (President: Shigehiro Nakajima) is pleased to release an updated road map for X mount interchangeable lenses.
A large-diameter medium telephoto lens (the XF90mmF2 R) features for the first time on the development road map for end 2015. The next available lens will be the XF50-140mm F2.8 R LM OIS WR. Following on from the XF18-135mm lens, this will be Fujifilm’s second weather resistant lens designed to partner its X-T1 camera.
Other updates to the road map include the previously announced “Ultra-wide angle lens” being confirmed as the “XF16mmF1.4 R” with a guide launch date of mid 2015. And the planned launch of the XF16-55mmF2.8 R WR lens moving to Spring 2015 and the Super Tele-Photo Zoom lens to Winter 2015.
Highly regarded for their outstanding image quality, resolution and well-built bodies, the unique X mount lens range now includes super-wide angle to super-telephoto range lenses and a large-diameter lens with rich bokeh and high resolution.”
