There is no lack of excellent reviews for Fuji X lenses, but excellence has a price. Fuji glass, particular the primes, is pretty far from affordable for most enthusiasts. For Nikon shooters wishing to take advantage of the iconic performance and great out-of-camera JPGs of Fuji X bodies but don't want to spend a fortune on Fuji's primes, this adapter is a real option to be able to squeeze more life out of 'old faithful,' that lineup of stellar Nikon F and G glass that many Nikon shooters have in their inventory.The lens to adapter side seemed a little tight the first couple of mountings, but has become very smooth with a little use. Lenses mount without play. The built-in aperture ring does a decent job of opening and closing the aperture in G lenses. As many have pointed out, the travel distance for aperture modulation of Nikon glass is very limited, so one may end up closing the lens down more than intended. Of course, there's also no way to know the precise aperture when using Nikon G lenses with this adapter.Once users become used to manual focus with their Nikon glass when using this (and other) adapter(s), and this should not be difficult with the focus peaking of most Fuji X APS-C bodies, they may conclude that the combination of Nikon lenses and Fuji X bodies is something special.Who knew that the drawer full of Nikon lenses would get repeated new leases on life on Olympus, Sony, and now Fuji bodies with adapters.
