I just got in my Nikon adapter in the mail yesterday figured I'd post a photo as adapters aren't written about often.
At only $20 it was actually worth it. This adapter will allow me to use AI and AF Nikon lenses on my Fuji cameras. I still have my 50mm 1.8G lens. I was thinking instead of selling it and losing about $50 on it to just get this adapter and just keep it. It fits the camera well and there really is no wiggle room.
I probably won't use it too much as it won't autofocus the lens, but I can still take full advantage of the Nikon image quality. And I'll get a ton of practice using the different manual focusing techniques with the Fuji.
Focus zooming - You can zoom in x10 on what you're looking at while manual focusing you can see exactly when you're in focus.
Focus peak highlights - When things start to come into focus via the viewfinder the edges of the area in focus will start shimmering. Pretty handy! Unless the scene is primarily white.
Digital split image - Just like in old film cameras where you have a grey square (image) that you need to align with what you're photographing to insure focus.
So, I'm sure to try all of these out further with the Nikon. I tried all of these with the fuji lenses and the focus zooming is really neat. Actually all are neat, just depends what works best for you. And how much time you have for fine tuning.
This is the first adapter I've ever bought, but I was surprised to see that Nikon and Canon mounts to work on each other are only about $15-$50. Not bad at all. Although there generally is no need to use a different manufacturers lenses unless you own more than one system. Who knew they were so inexpensive? Of course there are quite a variety of them and price ranges given what else you'd like for them to do. Worth a look though.
