a new weather resistant lens for the Fujifilm X system
uses the same mount found on the T model
has the biggest viewfinder (as of digital camera concerns)
weather resistant (body & lenses)
& more …and of course is priced accordingly :-) It is a Leica after all.

…a “reinvention” of the ZE & ZF series in a new wheather sealed body and Otus exterior design
