had bought a Fuji X-T10 mirrorless camera and was waiting for a Fuji lens to arrive so I could use it. I had a Nikon 35mm g at home and I was thinking about using it on my Fuji while waiting for the proprietary lens. After careful research I have ordered this wonderful adapter which I will try to describe below. It arrived in a small cardboard box wrapped in shockproof plastic. The adapter is made of excellent material, it is made entirely of metal and is pleasing to the eye. It can be installed easily and quickly on both sides. It has a metal ring that is used to close and open the membrane. That last feature deserves an explanation: the adapter has no electrical contacts, so any lens you mount will lose autofocus. If you mount a lens that is equipped with an aperture ring, you can use it without any problems because the adapter does not interfere with this ring. On the other hand, if you mount a lens without an aperture ring, as in my case, you can have trouble selecting the apertures that the mirrorless camera actually no longer shows on the display. However, this adapter features a ring for minimal control of the diaphragms. To get the best out of it, before mounting the lens, make sure the adapter ring is fully closed (smaller ball), then mount the lens. Then mount the adapter on the camera. In the case of the XT-10, I had to select non-lens speech noise from the settings menu and that was it. Despite the lack of autofocus and minimal control over the apertures, I took wonderful photos. Highly recommended for those who are already experts at manual focusing.
