The updated roadmap includes a new XF90mm f/2.oR lens slated for the first half of 2015. The next available lens though is the XF 50-140mm f/2.8R OIS WR lens, which will be the second weather resistant lens designed with the X-T1 in mind.
The previously announced “ultra-wide angle lens” will be the XF 16mm f/1.4R expected mid-2015 and the XF 16-55mm f/2.8 WR lens will move to Spring 2015. A super tele-photo lens will move to Winter 2015 on the roadmap.
