It's silver metal, and it's cool when you put it on. It comes in a plastic storage case, so it is convenient to carry when removed.

Flawless and effective product.
I finally mounted a Helios 44M lens (look for it and buy it too - results from prime lens) which, with another K&F adapter (EOS / M42), I can also use on GX80.
Punctual and reliable.
Very satisfied.

I was able to use my old lens (Prakticar f 70-210) from my old analogue camera with the adapter.
It doesn't have autofocus, but manual is fine too.

The quality of K&F Concept is indisputable, there are better brands, but the ratio, quality/price, is difficult to beat.

This adapter, has allowed me to use after many years, my old lenses of my analogic Asahi Pentax SP II, handheld lenses very good, to be able to use them with better machines.

I use it for astrophotography with a telescope purchased in the 1970s.

Originally purchased to try to attach a lens for film cameras to EOS70D.
It's working without any problems. Good job at this price.
Thank you

Unfortunately, the massive ring of the M42 on EF touches the AF contacts of the Viltrox Speedbooster and causes me to get an error message on my GX9. This problem does not occur with the P/K on EF from K&F because it has a slimmer design. Therefore 2 stars deduction. A successor to the adapter should have a recess at the height of the AF pins, I'll see how I can DIY my adapter.

This adapter comes with its own storage sleeve and feels very premium. Turned it on to my Pentacon 2.8/29 and plugged it into my Canon. The lens is recognized and the camera's exposure sensor works perfectly. Turning off the lens also worked without any problems.

Conclusion: High-quality adapter with good price/performance. 5 stars from me!
