A brief email this AM stated Fuji will announce Fujinon lenses for the EF mount in March. No other details were given. This is the first time I’ve heard anything on the topic. Grain of salt and all that.
There have been mentions elsewhere from time to time that Fuji wasn’t finished in the DSLR business.
This could also be lenses for video as pointed out by a few people, though the information did specify EF.
