Good autofocus, price and seemingly solid assembly, the only negative I see is when you put on a Nikon lens, the noise is like sand in the ports, I've already cleaned it and cleaned it with a pear , but the sound continues. I use it with Lumix gh5, g9 and Nikkor 50mm F1.8.

Good autofocus, price and seems well assembled, the only downside I see is when you attach a Nikon lens it sounds As if there were sand in the plug, I cleaned it with a pear and vacuumed it, but the noise remained. I use it with Lumix gh5, g9 and Nikkor 50mm F1.8.

Tried with Panasonic GX85 and a couple of Nikkor lenses. At first I found it very difficult to set the autofocus correctly. The problem isn't necessarily the adapter itself. It also has to do with how large the lenses are compared to the body, making it difficult to get a firm grip to hold the camera steady, especially with telephoto lenses. Manual focus works much better. The quality of the photos is also not very good, especially in low light. He seems to need a lot of light. So in my opinion
