Fotodiox Lens Mount Adapter Compatible with Contax G SLR Lens on Fuji X-Mount Cameras

Haven't tested with larger lenses but works perfectly adapting an old nikon 50mm to my fujifilm camera.

After a couple days of ownership, I put the adapter through its paces behind several lenses to determine the approximate exposure difference for each labeled setting. Hopefully, this will be useful for future potential customers.Aperture SettingsA quick note on my unscientific method: I tested four lenses including FX and DX, primes and zooms. Exposures were compared both with Lightroom and in-camera histograms and approximated as closely as possibly, to a third of a stop. Results may vary, as the adapter does exhibit some play at each setting and I doubt every copy will be exactly alike.Lens focal length: Setting 1 equivalent aperture, S2 Ap (difference in stops), S3 Ap (Δ in stops), S4 Ap (Δ in stops)16mm DX G: f2.8, f5 (-1 2/3), f14 (-3), max35mm DX G: f1.8, f3.5 (-2 2/3), f10 (-3), f25 (-2 2/3)50mm FX: f1.4, f3.5 (-2 2/3), f9 (-2 2/3), max70-300mm FX G @70mm: f4, f9 (-2 2/3), f25 (-3), max70-300mm FX G @300mm: f5.6, f11 (-2), f32 (-3), maxAs you can see, you can't simply assume that the four settings are equally distributed across the entire range of available apertures for each lens. In fact, I've found that, while in general, the exposure averaged typically to -2 2/3 stops per click, it was inconsistent at extreme focal lengths like ultra wide or long telephoto. While the physics of light and diameter are easy to calculate, this is not a precision instrument.I was pleased to find the widest setting does offer the widest possible aperture on all the lenses I tested from my f1.4 prime, to my telephoto. The narrowest setting often exceeded the maximum aperture available on my lenses and thus defaulted to that maximum figure.Build QualityI have several Fotodiox components including the static Nikon-Fuji adapter without the aperture ring. Their products feel solid and there's no play in the mount. I've never had trouble releasing a lens, as experienced with other brands. There doesn't seem to be any light leakage.My only qualm is the lack of certainty with each setting. The sound of each click is quite pleasant and communicates effectively. However, the tactile feedback lacks confidence, as there is a bit of spongy play at each notch, like a rubber band is all that keeps you in each groove. You can slightly rock the grip back and forth between settings and even ever-so-carefully force an intermediate setting, but it doesn't stay, and slowly slides towards one notch or the other which can wreak havoc on your exposure settings. It's probably best to stick to one of the four where the ring won't be tempted to move.SummaryAll in all, I'm pleased with the adapter. It allows me to use my "G" lenses without aperture rings. I wish there were more aperture settings than four and that they inspired a little more confidence. But it does cover my most used settings on most lenses: wide open, ~f4, ~f11. On a personal note, I'm also not a huge fan of the blue ring. I'd prefer black or silver to blend into the X-E1/Nikon combination.

I got this set of extension tubes because of the low price. However, the old saying ("you get what you paid for") seemed to come true. The tubes arrived and I tried each on my camera, and then all together. The fit was very tight and I had trouble tightening the tubes to the point where they would lock. In fact, they were so tight, I felt like they might damage the base locking plate on the camera, or the locking plate at the back of the lens. Once on, I experienced the same trepidations when trying to remove the tubes.When examining the tubes out of the box, I noted that the 14mm tube had no markings on it to designate the size. Because of this I returned it through Amazon asking for a replacement set. When the replacement set arrived, I unboxed them and found the same problem. The 14mm tube had no markings on it to designate the size. Once again, I went through Amazon to request a replacement, but got the message that a replacement was not possible and that I could either have a refund, or contact the manufacturer and try to resolve the problem. I did not want to waste further time in dealing with this product which should have been properly labeled in the first place, and which I considered so tight on my camera that it might cause damage to either the camera or the lens mounting areas.So, I returned this cheap Fotodiox product and bought the JJC Auto Focus Macro Extension Tube Set which is more costly. I may not even use the auto focus feature of this extension tube set when doing macro photography, but this tube set fits properly onto my camera like one might expect of a well-made quality lens, the components are properly labeled, and I am (therefore) much happier with this purchase.

This Fotodiox FD to FX adapter lets me use my two canon FD lenses with my fuji X-T1. I have a Canon 200mm FD lens and a Kiron 80-200mm lens in the FD mount.One should remember that there is no electrical communication between the lenses and the camera body. The adapter isn't built for that. I use these FD mount lenses because the lenses have the ability to directly adjust aperture. The fuji X-T1 can choose an appropriate shutter speed if I have it set on aperture priority, but I mostly go with manually choosing the shutter speed.When using this fotodiox adapter, because there is no electrical communication between lens and camera, one must manually focus. That isn't a problem, even with my aging eyes, as the fuji X-T1 has the focus peak option for focus assist. I generally go with manually focusing even with the fuji lenses that can communicate for auto focus.The old Canon FD mount is a pretty fiddly mechanism. There are weird things one must do when attaching an FD lens to a camera or an adapter so that the aperture ring on the lens works properly. A lever needs to be in the correct position, ring locks must be locked. Now I'm just using the Kiron 80-200mm lens as it gives me more latitiude, so it's always on the fotodiox FD-FX adapter.This fotodiox adapter, like the others I have, fits snugly onto my fuji X-T1. All these fotodiox adapters fit to their designated lenses well. No rattle.I have Nik-FX for my nikon/nikkor lenses. I have M42-FX for my old Pentax mount lenses, and I have EOS-FX for my Canon EF lenses, and this one for my FD lenses. I'm very satisfied with all of them.If you're going to go with one of these, you should understand clearly the inherent limitations of them and not be expecting more than for what they are designed.08Sep15: I ordered a second FD-FX adapter, and I've been using this new one for a week. There are three tiny phillips screws that hold the metal ring one can see in the photo which accompanies the product title. Well, one of those three screws became extremely loose, one mild to moderately loose, and one did not come loose. I tightened them and the adapter is again working perfectly. I'll post if this turns into a recurring problem.24Oct15: That second FD-FX adapter's tiny phillips screws have loosened again. Two had become quite loose and the third mildly loose. Not cool. Downgrading from 5 stars to 4 stars. I haven't had a problem with the first adapter. I'm wondering if there might be some problems with quality control over large lots.

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!

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.

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.

Bought this adapter to use my Nikon 50 1.4d & 1.2ais lenses on my XE1.The adapter is well made and solid, it mounts quite tightly to my Nikon lenses but is an easier fit to the camera; it has no slop or play when is use. It is discrete and when mounted with a lens it looks good and does not look out of place.When using my Nikon 50 1.2ais the camera feels unbalanced and not pleasant to use because there is a lot of glass and metal in the 1.2ais and the adapter moves the lens further away from the camera, the 50 1.4d is lighter and easier to handle on the camera - although, still slightly unbalanced. Both lenses have aperture rings, smooth focus rings and work fine on the XE1; if you intend to use Nikon G type lenses with this adapter they will not work properly because you lose aperture control.The adapter looses a star for a couple of small machining marks and the lever to remove your lens is quite stiff and is not smooth.Overall, the adapter is good value for money and generally well made.
