M42 to Fuji X Lens Mount Adapter

I ordered the K&F M42 to Fuji FX adapter not knowing whether it would work well with the old Helios and Jupiter lenses I was hoping to use. It works perfectly! The adapter's an all metal build and feels well made and sturdy. It fits snuggly with the lens and the body of the camera (in my case the Fuji X-T10), there's no wiggle or movement once mounted. The adapter has a removable flange for those lenses that have an aperture pin that needs pressing in order to shoot anything but wide open. No need to modify the lenses to keep the pin pressed which is great! I didn't see any reviews that mentioned the flange, so was extremely happy to discover it was there. I haven't had any issues with focus to infinity using the adapter on any of the M42 lenses I've tried. They all appear to work perfectly. Obviously all lenses will be manual focus only, but if you're buying one of these adapters I'd expect you already know that. Set the camera to shoot without lens, and switch the focal lenth to that of your lens and you're off! Focus peaking also works a treat with these older lenses.

Old lenses don't die - the live again via a K&F adapter This is the second K&F adapter I have purchased and like the first it is exactly as described, well made, has a nice tight fit to both mounts and works perfectly on my Fuji. If you have a mirrorless camera and any old lenses I would highly recommend giving them a new lease of life via one of these adapters. I'm using this one to mount my 1959 NIKKOR-H 28mm f3.5 to a Fuji X-T1 which not only looks great as a combo it works well, is easy to focus, meters correctly and I'm having great fun shooting with it. EDIT: Picked up a third K&F Adapter this week for some Carl Zeiss lenses I have. Looking forward to a battle of the Nifty Fifty's EDIT: The count is up to FOUR now and they're all superb. Really can't knock the quality in any way, they're excellent value for money and the life they bring to old lenses is priceless. EDIT: Make that five as I added one with a m39 thread to use an old Jupiter 8 lens

Nice well machined, well coated adapter. Looks good too. Unlike a cheaper version I tried the release catch is well designed and doesn't let light in, so the extra money (this is thrice the price) is worth it, and I didn't have to wait several weeks to get it. Using a 1970s Summicron-R 50mm lens it takes suberb photos on my Fuji XT-10. Note that this transmits no lens information to the camera, neither mechanically (from a Leitz lens cam) nor electronically if your lens has contacts. So it has to be used with a camera which has automatic shutter control or be used manually.

If you have a Fuji X mirror-less camera and also some old M42 screw thread lenses, then this is the kit for you. Fit this between the camera and the lens and you have a perfect, stable conjunction between the two. It has been made out of what appear to be good materials, brass I believe, with what appears to be good metal mounts at either end. There is, of course a down side to using these adapters and that is that you have to manually focus the lens, manually set the aperture, and because of the crop factor of the APS-C sensor a 50mm lens is halved again and becomes a brilliant 75mm portrait lens, but with the advantages of the 50mm lens - in other words the depth of field remains the same, as does the aperture so you do not lose any speed of the lens with this adapter. For an example if the 50mm lens was a f1.4, then on this adapter it becomes a 75mm f1.4!! Try buying one of those for this sort of money. Many may find this a backward step, but it is something that you soon get used to doing The advantages are that M42 screw thread lenses can still be acquired cheaply by today's standards, some as cheap as £20-30. Add the prices of the adapter and you still have a very cheap lens, especially when you consider that Fuji XF lenses tend to sell at about £500-600, and remember a lot of these old lenses are built solidly of metal and glass with hardly a glimpse of plastic anywhere. Treated well will last a lifetime as well as given brilliant results.

The product is the Olympus OM mount to a Fuji X series mount. The object of the exercise is to try and use 3 OM prime lenses, 35mm, 50mm and 135mm, on the Fuji X-A2 mirrorless camera. Very fast delivery, well packaged. The adapter is well made and looks good. Initially the OM lenses did not seem to lock in the adapter and fell off, other reviewers have had the same problem, but... the OM lens have a little button on the side which you press to hold in the metal latching catch, if I held in the catch and then turned the lens firmly in the adapter it locked perfectly. The adapter was easy to attach to the Fuji camera, turn and click. So the adapter now fits snugly. I have only had chance to take a few photographs, remember the lenses are manual lenses, so set the aperture on the lens, perhaps set the focus to infinity on the lens and then on the camera(Fuji specific) set the option take photos without a lens, use aperture priority and manual focus. To get good photos you need to understand and practice these techniques. To buy 3 almost equivalent Fuji lenses would cost nearly 4000 pounds, the adapter with delivery was less than 25 pounds.

Another well made product from K&F

I've had a very nice Pentax 50mm 1.4 SMC in K Mount that I used to use back in the day when I shot Canon. I kept meaning to get an adaptor because it's been described as one of the best 50mm lenses ever made, but it's been sat in its box for 10+ years. Too lazy. Anyway, finally got my finger out and bought this adaptor. Fits well, shoots well. It's a manual focus set up of course, but easy enough to deal with. See the first shot I took at 1.4. Renders nicely. Nothing special as a picture maybe, but gives an indication of quality of this combo. You need to set the menu as allow shoot without a lens, or nothing happens when you press the shutter.

Je l’ai depuis plus d’un an maintenant et je ne regrette pas, pas de jeu, pas de dégradation précoce. Je sens que la fixation remplie bien son travail, cela semble très solide. Bien sûr, cet article ne gère pas l’auto focus mais cela nous force a prendre le coup de main en manuel 😜 Je recommande !!!

Adapta perfectamente a la fujifilm X-T2 mis lentes nikon 14-24 2.8, 24-70 2.8, 70-200 2.8 y las sigma 105 macro y 150-600 sports. Naturalmente es totalmente manual: No hay autofoco, No hay estabilizador. No tiene diafragma como tal (no se puede elegir entre 5.6 o 8 o 11), no tiene numeración. Pero tiene un anillo que abre y cierra el diafragma y con él puedes graduar la luz que entra en cámara y la profundidad de campo (cuando más abierto menos profundidad y más luz). Al tratarse de una cámara sin espejo la medición de la luz puede ser automática si: - Iso automático, elije velocidad, situa el anillo-diafragma donde gustes. - Elije iso, pon velocidad auto y situa el anillo-diafragma donde gustes - Iso automático, velocidad auto y situa el anillo-diafragma donde gustes. La opción que no es posible es la de diafragma automático. También dispara todo manual y controlas la luz por la pantalla. Por el precio que tiene no se le puede pedir más.

Produit précis, impeccable et robuste. Fonctionne très bien sur Fuji XT-3, XT-5 et X-Pro. Avec cette bague (qui ne permet aucune communication d'informations électriques entre l'objectif et le boîtier) vous devez évidemment mettre TOUS les paramètres de l'appareil en manuel : la mise au point; les ISO (100 si soleil, 200 si nuages, 400 ou 800 en intérieur...); la vitesse (125 centièmes de seconde par défaut, ou 250 si soleil, ou 60 si sombre) et régler l'ouverture souhaitée directement sur l'objectif. Idéal pour les objectifs vintage (point d'attention : vous devez paramétrer votre boîtier avec la fonction "Prise de vues sans objectif : OUI"). L'infini fonctionne très bien. Astuce, utiliser l'aide à la mise au point que proposent beaucoup d'appreils : la zone nette s'affiche en rouge. Très bons produits.

Prodotto corrispondente alla sua descrizione sul sito, viene fornito in un funzionale contenitore di plastica. La costruzione è interamente metallica, solida e robusta. L’innesto dell'anello nel corpo macchina è un po’ duro, ma l’ancoraggio è solido e senza gioco. L’innesto dell’obiettivo nell'anello richiede un allineamento dell’ottica molto preciso, bisogna fare attenzione a che l’ottica sia solidamente ancorata in sede, muovendola leggermente dopo l’innesto, per assicurarsi che essa sia stata effettivamente agganciata, altrimenti potrebbe scivolare via con il movimento della macchina. Per il resto, il prodotto svolge egregiamente la sua funzione. In sintesi, prodotto consigliato.

Funciona a la perfección. Solamente tengan en cuenta que es para los lentes new FD, es decir los del botón plateado. Con los lentes de anillo y los FL, suele tener problemas
