FotodioxMacro Reverse Adapter Compatible with 58mm Filter Thread to Fujifilm X-Mount Cameras

Cheap adapter, however it doesn't allow autofocus lenes to use autofocus features. Excellent for manual lenses.

All comments pertain to the Nikon-to-Fuji X-mount version. The adapter does exactly what it is said to do -- allow use of Nikon M mount lenses on a Fuji X series body. Note this version will NOT work with G-series Nikon lenses. Those are the ones without an aperture setting ring; there is a different version available for those. Both the camera-adapter fit and the adapter-lens fit were good. Easy to mount and to remove. Everything felt secure with no wiggle. That sums up about all that is claimed.For those not familiar with the product:There is NO autofocus. There is NO aperture control between the body and the lens.Despite the above, taking photos is actually pretty easy. The first step is to go into the Fuji menu and select "Shoot Without Lens" and set it to "ON".Exposure - You can either set the camera to manual exposure and use it just like you were using a Fuji lens. Or you can set the shutter speed dial to "A" and use it like "aperture priority". You loose some information that is normally in the viewfinder but the exposure aspect of shooting is otherwise pretty much like you get with a Fuji lens but without shutter priority.Focus - Manual focus only. If you are using a Nikon wide angle using the distance markings next to aperture ring may be all you need. I don't find my purely visual focus very accurate - you may. A better way to use focus peaking. (On my X-E1 you need to update to the latest firmware and be sure the focus mode is set to M.) Try this on your Fuji before your buy the adapter to be sure you and focus successfully. If you find this doesn't work for you using a Fuji lens there is no value to buying the adapter. (PS: I find manual focus of a Nikon lens on the Fuji is easier than manual focus on a Nikon body!)Why would one want to use a Nikon lens on a Fuji X?A- you own one or more Nikon lenses and you are just naturally frugal.B- You are not fully committed to moving to mirrorless body and don't want to commit buy buying a bunch of lenses yet.C-There are certain capabilities the Fuji lens line up lacks: 1:1 macro, exotic features like the Nikon's DC lenses or tilt/shift lenses.D- you have some non-AF Nikon lenses (Ai-S) and focus peaking manual focus works better than what your Nikon body offers.Much of this probably applies to other mounts such as Canon, M42 etc as well as to NikonB- you are making the transition to mirrorless but are not sure yet

I've never really manually focused a camera. Sure I have an 8mm fisheye that lacks AF, but at 8mm, just about everything is in focus. That being said, I had that same 8mm lens, a 85mm/1.8 D, a 10-20mm/3.5 and a 18-300VR beast for my Nikon, and so little glass for my new X-E2. While I didn't plan on using my 18-300VR at on with this, and I don't plan on using my 10-20mm/3.5 much on my Fuji, the other two lenses seemed ripe for experimentation.The mount attaches firmly and without and grittiness of scraping. Likewise the lens attach to it without an issues, and everything is secure. The overall fit and finish inspires confidence. There's not much to it, as it's basically a machined alumninum tube, albeit with a few tricks up its sleeve. For one, it supports "G" lenses (those without aperture rings). The two lenses I wanted to experiment with do have old school aperture rings, and they work well. Either you can let this adapter control things (as it would for a G lens), or use the ring on the lens. Either way, it worked well, though the aperture adjustments on this adapter are very basic, so you won't have as much control as you would with an aperture ring of the controls on a modern Nikon camera.Just to be clear what work means, there's no data going to the camera, so it never knows the aperture, there's no lens correction, and focusing is manual. It was relatively easy, even for a novice like me, to manually focus even the 85mm/1.8 D at f/1.8 on the X-E2. I enabled focus peaking, and I also used the distance scale. The latter got me in the ballpark, and the former helped me fine tune things. Honestly, I think I could get rather proficient with practice, but for now there is no muscle memory, and it's best for deliberate moments, rather than on the fly shooting, which is nice for a change anyway. I'd set your expectations based on your previous experience, though in the end, I think most if not all users can have great results, with the right lenses.I'll try to post sample images shortly.
