Fotodiox Lens Mount Adapter Compatible with Pentax K Mount (PKAF) D/SLR Lens on Fuji X-Mount Cameras

The Adapter seems of Decent build but it does not turn seamlessly in Camera mount and gets stuck, can cause damage to mount and also risk of permanently being stuck.

One side of this is a Fuji-X connector which you fit to your camera body in the same way you'd fit a regular lens, and the other side is a circular screw fitting that you can attach to the front filter thread of your lens. This means you can fit your lens on backwards. If you don't know why you'd want to do that, then this review isn't going to shed any light on that...I'd suggest you search for 'reverse macro' via your favourite search engine.It's made of decent quality plastic so should last a long time, and is a good fit to both the Fuji-X and filter thread connectors. This is simply a piece of plastic and doesn't contain any electronics so once your lens is fitted in reverse, you're in full manual.One thing to be aware of is that Fuji-X lenses use an 'aperture-by-wire' system and even though most Fuji lenses have an aperture ring, aperture is controlled by the camera body at the point of taking the shot. This means that regardless of what the aperture ring indicates, the lens will always be at maximum (i.e. widest) aperture when it's not attached to the camera. Using this adapter and attaching a lens in reverse is the same as having no lens at all as far as the camera is concerned (like I said, this is just a piece of plastic with no communication with the camera body). There are ways around this, but they're clunky at best. I intend to buy an old Nikon lens that has manual aperture control for use with this reverse adapter.

Really impressed with this Fotodiox Pro OM-FX adapter. I also own the Metabones version and the MB one, whilst fitting the FX well, is very tight on original OM lenses. It's just about ok. I also have a Panagor OM mount lens and that is way too tight on the MB adapter. This Fotodiox Pro model however fits everything really nicely. It feels as it should on both sides of the adapter and with all lenses. It weighs 104 grams compared to 133 grams for the Metabones. The MB feels very solidly made with top quality materials, but at the end of the day, if it doesn't fit properly, what use is it? The Fotodiox Pro is still really nicely made and actually the high quality black satin finish really closely matches the original Olympus Zuiko lens finish, whereas the MB finish, although nice, is shinier and therefore not as good a match. Both versions have an Arca Swiss compatible mount (removable) for tripod use. Full marks Fotodiox!

I bought this in order to use my Nikkor 24mm f1.8G on my Fuji X-E1. I knew the lens had excellent corner-to-corner sharpness as I've used it on 35mm film and it's one of my favourite lenses for such.The Fotodiox adapter is extremely well made, fits perfectly to both camera and lens, shift and aperture controls are v smooth and well-damped (although the throw of the latter is very short)Obviously you can't get precise aperture clicks so I just looked through the front of the lens and turned the ring until it looked about halfway stopped down. I didn't want to use fully stopped down because of diffraction.Contrary to my expectations, aperture-priority metering gave perfect results even with the lens fully shifted.It's not easy to focus a G lens manually, there's no infinity stop (although you'd be unwise to trust such with an adapter anyway) so it's worth taking great care over that. I assumed a stopped-down 24mm lens would get everything, I was wrong! I think probably it can focus beyond infinity, but if you're careful it'll be fine.Possibly the 20mm f1.8G would be an even better match for these purposes (= 30mm) but I like the "natural" perspective the 24mm gives.One caveat: the edge of the dedicated Nikon lens hood was just visible in some shots. Best leave it off, ditto filters.But for £84 this is a really good piece of kit. I haven't tried an actual shift lens on my Nikons but I don't see how they'd do a better job. And I'm not about to start shooting 4x5!

The Fotodiox Nikon to Fuji lens adapter allows Nikon lenses with aperture rings, to fit to Fuji's X system cameras (there is a different adapter or Nikon 'G' lenses). The reason I went for the more basic adapter is because I have plenty of older lenses and my newer Nikon lenses tend to be zooms, which are much bigger and heavier, so not really ideal for mounting on an X-E1.The basic idea is that by adding the adapter, you increase the flange distance between the camera and the lens and add system adapter to the camera (in this case the Nikon F mount). The system is really basic and works well. Everything works manually and you have to set the camera to work without lenses, as there are not contact points between the camera and adapter. Aperture is handled through lens and you have to manual focus (which isn't to hard, even at low apertures, with the X-E1 zoom and focus peaking ability).The build of the adapter is very good, it took me a few minutes to work out how to remove the lens (there is a round button, which I tried to push and pull (in fact you need to slide back to open the lens lock). I would suggest, that Fotodiox create a small video showing how unmount lens process and put it on their site.I have a small problem with importing the product Fotodiox were very good and refunded the extra money I had to pay very promptly after I raised the issue with them.All in all I am very pleased with the adapter.

Ordered on Tuesday, delivered on Wednesday on a free delivery option!Great lens mount adapter, a bit dubious as not a major 'brand name' from my knowledge but a great, well made and quality finished adapter (could have been made by Fuji) i.e. it doesn't look cheap).Allows me to mount manual Minolta lenses to my Fuji XT-2. Quality and appearance blends in well with the camera finish and doesn't look out of place, nor does it affect the handling of the camera/50mm lens combo.Happy purchase so far......
