Advices:

Infinity focus position:
The position of the infinity mark [∞] of the telephoto lens or super telephoto lens is shifted slightly to the positive side to enable focus adjustment even when focus shift is caused due to temperature changes. The shift range is denoted by an L-shaped line, Be sure to check the focus through the viewfinder even when you shoot at infinity.
'No Lens Attached' - Warning Message Appears:
The camera needs to be set to function without an E-Mount lens attached. You can do this by changing the following camera setting: 'Menu' -> 'Setup' -> 'Release w/o Lens' -> 'Enable' (Exact naming and location of this option may change depending on camera model). If your lens does not have a manual aperture control ring, it will stop down to its smallest f/stop by default.
Set camera "release shutter without lens" to enable when using the adapter for the first time, or the camera will fail to recognize the lens and the shutter may not be released.

Works great.

Mount adapter works fine on my X-T1. Seems very well made, and fits just like a Fuji lens mount--no tightness or difficulty in mounting, unlike one or two other reviews. I'm pleased and the price could not have been better. One benefit I had not expected is that I can use my old Pentax screw mount prime lenses as well. Those were some very nice lenses that have gotten minimal use in the digital age.

I definitely recommend this adapter

I recently acquired a vintage Asahi Pentax Takumar 50mm 1.4 that I wanted to play with so I went ahead an purchased the K&F Concept M42 to Fuji X mount adapter. Honestly, I did not know what to expect given that I have never used a non-native lens on my beloved Fuji X-T1 before. When I unboxed the adapter, my first impression was "wow...solid build quality". So far I am enjoying both lens and adapter. I definitely recommend this adapter.

Great, my girlfriend loves it

A friend of mine has used KF K&F Concept's camera adapter, it fits very well and the quality is very good, I will try it too

Perfect for Fujifilm XT-2 to Honeywell 300mm telephoto lens.

Works as intended. Can’t speak to autofocus, as the lens I’m using can’t interface with my camera in that way (super old lens, relatively new camera).

Excellent Quality

Received adapter quickly and well packed. It has solid construction and works exactly as described.
I have used a few m42 screw mount lenses on my Fuji X-T20 and all worked perfectly in fully manual mode.
If you don't mind, like me, working in manual focus mode and have good eyes it is a great inexpensive way to have old great manual lenses on your digital camera.

I consider this purchase good investment for my needs.
BTW, just bought one for Nikon lenses as I can get great Nikon mound lenses for a great cost.

K&F is always great brand.

K&F is always great product. I always pick this brand first if it’s available and this item does not disappoint.

Better than expected.

Great quality. Had no issue with the way it fit my Xt3 fit just as well as the kit lens I got with it. Locks in smooth and holds right with no jiggling or feeling loose. I have a very large and heavy 80-200mm lens that weighs at least twice what the camera does and was really worried about the fit and it breaking something. But it is surprisingly rock solid. This is a great brand, I now have 3 types of there adapters.

poor service but the product gets the job done

Everything looks good other thanone small thing. The box that contains the lens came already broken. There wasn't any broken pieces inside the package so I know it wasn't broken during shipment. It bothers me to think that they would send you a already broken product.

Adapting to the new gear.

Well made, fits the thread very well and not loose or ill fitting. Metal surface fitting for the lens and not plastic so will last longer and not wear out as fast over time. Would buy this brand again.
