There is no shortage of excellent reviews for Fuji X lenses, but excellence comes at a price. Fuji glass, especially the Primes, is far from affordable for most enthusiasts. For Nikon photographers who want to take advantage of the iconic performance and great JPGs of the Fuji X bodies without a camera, but don't want to spend a fortune on Fuji's primes, this adapter is a real option to get more life out of 'Old Faithful', the Set of outstanding Nikon F and G lenses that many Nikon shooters have in their inventory. The side between the lens and the adapter seemed a little tight for the first few mounts, but has become very smooth with a little use. Lenses can be mounted without play. The built-in aperture ring allows for proper opening and closing of the aperture on G lenses. As many have pointed out, the aperture modulation travel of Nikon glass is very limited, so you may end up driving the lens further down than intended. Of course, there is also no way to know the exact aperture when using Nikon G lenses with this adapter. Once users get used to manually focusing with their Nikon glass when using this (and other) adapters, and this shouldn't be difficult given the focus peaks of most Fuji X APS-C bodies, they might come to the conclusion come that the combination of Nikon lenses and Fuji X bodies is something special. Who would have thought that the drawer full of Nikon lenses on Olympus, Sony and now Fuji bodies would be revived over and over again with adapters.
