Well built adapter, with mounts without play or hardness, in my case the M42 thread was not well aligned with the upper focus mark of the lens but it is quickly solved with the 4 allen screws that hold the "silver" metal thread on the sides, if you do not have the necessary tiny allen key, as in my case, you can use a torx screwdriver that fits well that loosens and tightens them without any problem, a small assembly fault, but sometimes it can be good to be able to adjust this turn, such as when using extension rings or similar cheap accessories that probably are not perfectly calibrated. The assembler on duty was having a bad day, he stays with 4 stars for "craftsmanship".

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

Fits really well, creates a nice solid mount with little to no loose connection ensuring focus pulling is never shakey

Was recommended this by a photographer friend and can agree, it's the best adapter ! Not at all wobbley. Great way to get more use out of some of the excellent lenses, that can be found quite inexpensively these days, on a modern camera.

Excellent product. Very good value. A great way to bring new life to an old lens. I am impressed with the quality of the K&F Concept and the service I received.

In my opinion, K&F-Concept is the best of the inexpensive adapter manufacturers. The M42 adapter goes slightly beyond infinity (positive for me) and you can turn the M42 thread insert by loosening the Allen screws (Allen 1.3mm) so that the labels on the lens (depth of field scale, aperture scale, distance) are aligned exactly upwards. I would definitely recommend it. I use various K&F adapters (M42, Exakta, Canon FD) and am really happy with them.

It is an adapter for old lenses that use M42 (pink) to Sony and that does not keep anything secret that cares about electronic contacts. However, it is not advisable to buy any adapter, even if it is more expensive because it can give you holes and not adjust well. This KF Concept stands for perfection, well built (totally metal) and aesthetically very good. I am a user of various adapters of this brand and I am very satisfied. Totally recommendable

Out of this box this feels solid. Connects to my camera body without issue and works pretty well from what I can tell. I only have one older lens so I havent done extensive testing on this but what I have works like a charm so this is great. Cant wait to expand my lens collection and put this through its paces. Very happy with this.
