Review: Great quality all metal build, with removable flange for aperture pin,. - 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.
Review: Old Lenses Don't Die ***Updated*** - 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

## Questions & Answers

**Q: Is it suitable for my fujifilm xm-1? i want to use olympus 50mm 1.8 om zuiko on my xm-1.**
A: Not sure why you'd want to, as the xm1 has the equivalent of 50mm on its standard lens. Adding the adapt or will add 20 to 30mm, but it will work. I bought it to use a 17mm but by the time it added 20 to 30 it didn't give me  anything I didn't already have on the xm1.

**Q: Can I use manual focus AI & AIS lenses on the Nikon G adapter? Thanks!**
A: Yes these lenses should work fine with a Nikon G adapter to Fuji X mount.

**Q: Would this fit and be suitable on a canon 700D & 2000D at all please.**
A: The EOS to FX adapter is for the opposite situation - using a Canon EF mount lens on a Fuji FX body. Hope this helps.

**Q: Is this good for Nikkor 85mm f1.8D?**
A: NIkon to Fuji X lens mount adapter you are asking, yes, your NIkkor 85mm F1.8D lens is Nikon F mount, could be used on this adapter as long as you have a Fuji X mount camera.

### ⭐⭐⭐⭐ Fits well, nice quality, does the job
*by D***E on 13 August 2019*

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.
