I bought this product because I already had other K&f concept adapters for Pentax K to M43 that I was happy with.
So I bought the Sony E adapter for my son. This now allows him to use his Pentax K lenses on his Sony A7 (operation verified with DA15, FA31 and FA77).
I chose the model with a ring that allows you to adjust the aperture of your Pentax lenses without an aperture ring (for example DA15, DA35, DA55-300) by acting on the clutch lever on the mount, and of course with the lenses which are equipped with an aperture ring (FA31, FA77 and F135, M50 and M28).

The adapter fits snugly into the bayonet on both sides, but not too tightly. The aperture ring for lenses without its own has a slight grid, fits well and can be adjusted comfortably. Since it has no gear ratio, the adjustment path is quite short.

In fact, my only complaint would be that the red marking on the lens side was stuck about 5 mm away from the actual bayonet attachment point. But since I already had it in my blood the second time I changed the lens, it's not worth a full point devaluation for me. Overall, I think the adapter is too good for that.

K&F has created a very high quality lens, the materials are very good and resistant. I have tested it by mounting a Sigma 18-35 on a Canon EOS R series and it works wonderfully.

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.

Great all metal construction. Perfect for recovering old Penzax K lenses.

Great purchase with an excellent quality/price ratio.
The ring is well made, made entirely of metal
it fits perfectly into the camera
just as the K lenses attach without any problem!
The only shame is that it does not have caps (a minor problem)
HIGHLY RECOMMENDED!!!

It fits perfectly from the Canon lens to the Sony A6000 camera, although only manually. If the Canon does not have a diaphragm in the ring that you can turn by hand, it does not work.

The price-performance ratio is right!
The goods arrived on time, as usual from K&F Concept. As far as I can tell as an ambitious hobby photographer, the product does what it promises. In any case, it meets my personal expectations. Its durability remains to be seen. However, based on my previous experience with other products from the company, I assume that this autofocus adapter will also serve for a long time. The feel and appearance are of high quality in my opinion.
