Fujirumors reports that:
Fujifilm is working on a Super Fast XF lens, that will have a widest opening of F1.0. The source says that the specs are not final until now, but the focal length planed at the moment is around 30mm.
Would be awesome if Fuji would really do it! A lens to remmeber, a lens few will buy but that will make you WOW thinking at it :)
