When this adapter is used according to the instructions and each lens used is set-up properly on the Fujifilm X body, it works on any Nikon lens. The very best results come by mounting Nikon's wonderful AI-S Manual focus lenses or "D" lenses because they have aperture rings so the aperture can be set on the lens and not on the guess-work, un-marked aperture ring on the adapter. Having said that I have had excellent results with the 50mm f1.8G and 35mm f1.8G lenses by simply setting the Novoflex ring in the middle of the range. I have even used the monster 300mm f4 lens with this adapter on my X-E2, but the longer the focal length, the harder focusing becomes. I would recommend not using Nikon's cheaper zoom lenses. Prime lenses simply work better and because of the excellent focus ring action on the AI-S lenses such as the 50mm f1.4, the 55mm f2.8 micro nikkor, the 105mm f2.5 and the 180mm f2.8, precision focus is more easily attained. I have also used Zeiss manual focus lens such as the 28mm f2 ZF, 25mm f2 ZF and the 50mm Makro Planar f2 ZF with excellent results. Using high quality manual focus lenses makes the whole shooting experience a pleasure and the precise focusing of these lenses will yield stunning results in the right hands.
The cons: Though this adapter is a precision tool, it still seems a bit over-priced and the lens release button is small, and definitely not easy on the fingers to operate (thus the 4 stars)
