For portraits I have the adapter 2 x ordered a Nikon lens and the Lensbaby at Fuji XPro1s. fits. everything ok as described by other reviewers, thank you very much! In Camera Rose switch to manual lens and the EVF is super-fast, almost like a reflex camera. at any rate faster than with AF and Fuji lenses. The mechanical quality is clean, nothing hakelt my housings or the two lenses. Since I shoot in Aperture 1.4 to 4 is the working aperture no problem-and unlike Nikon I see in the viewfinder the exposure compensation of - to +3. Upon further dimming no artifacts how that was used in reflex cameras-it is only a little darker, that's all. So for Fuji fans buy recommendation.
