K&F Concept Lens Mount Adapter with Aperture Control Ring for Nikon G/F/AI/AIS/D/AF-S Mount Lens to Fujifilm Fuji X-Series X FX Mount Cameras with Matting Varnish Design for Fuji XT2 XT20 XE3 XT1 X-T2

I use it as an adaptor for Nikkor 50mm 1.8 (manual lens). Remember to close the aperture dial on the adaptor if you're using a similar lens.

Aunque en los objetivos tipo G no llega a indicar el número de apertura, permite el uso completamente manual de todos los objetivos con resultados bastante buenos

El producto está bien construido, es de metal, funciona bien, te deja abrir y cerrar el diafragma, hay que tener en cuenta que al adicionar un objeto extra que separa más el lente del cuerpo, pierde mucha luz, en interiores hay que colocar al menos dos flashes.

I got this adaptor to adapt my old MF nikon lenses onto my Fuji x-s10. I got the adaptor that is for "g" lenses (it has an aperture ring) since I also own Nikon g lenses. There was some question of whether it would work with MF lenses or not. The answer is YES!To use it with MF lenses, you have two options for controlling the aperture. Option 1) set the adaptor aperture ring to it's widest setting, and use your lens aperture ring to control your aperture. Option 2) set your lens aperture to it's smallest setting (f/22 or f/32), and use the adaptor aperture ring to adjust your aperture. NOTE: option 1 is probably the best option in most situations for reasons too complicated to get into here.The fit of the adaptor is perfect. It is tight, both on the camera and at the lens, however I don't think it is too tight. There is extremely minimal wobble. I have to torque on the lens to feel it shake.The adaptor quality seems very good. The aperture ring turns smoothly with nicely dampened clicks. The box it came in is a nice touch.I'm very happy with the purchase.

Fit is perfect, function is perfect, quality is perfect, what more can I say except thank you Amazon for speedy delivery.
