There were too many manufacturers to choose from, so I went for something expensive with more details ^_^

Everything is high quality, screw it on, click it in, done. I like the M42 lenses because you can recognize them immediately,
that makes it easier to find lenses and the adapter works perfectly with my EOS 500D.

Everything is fixed, everything is secure, great pictures. A little getting used to because the aperture is not set in the camera - that has to be adjusted on the lens. Otherwise everything is as usual. Perfect for beginners.
And then you have an infinite number of nice old lenses to choose from.

High quality adapter (you can expect that for THAT price!) - nice detail: it says M42-EF on the adapter, so you can't go wrong and don't have to search for anything, other manufacturers should take this to heart too: write something on it about what it does, that would make life easier for many people...
Expensive, but serves its purpose, fits on EOS 500D Expensive, but serves its purpose, fits on EOS 500D

I recently purchased the K & F Concept M42 Mount Adapter to Canon EF Mount, and I am thoroughly impressed. The all-metal construction gives it a premium feel and durability that stands out. It feels solid and well-made, just like most of the items I’ve purchased by K & F Concept. The fit is perfect—smooth and secure, with no play or wobble when attaching lenses. It allows me to use all my vintage M42 lenses seamlessly on my Canon EF camera’s, unlocking new creative possibilities that these vintage lenses provide.

As always, Amazon delivered the item very quickly, and at a competitive price point, this adapter offers excellent value, plus it comes in its own hard case, which is a bonus. Whether you’re a hobbyist or a professional, this is a fantastic addition to your gear. Highly recommended!

It does what it is designed to do very well.
No issues with this product, all my M42 lenses can now be used on my Canon 6D and it works great.

Seems very solid, autofocus works quickly and reliably on my XT30ii with Sigma 18-35. I can recommend it - especially for the price.

Betrayed by the age and weight of the bodies and lenses, I bought a lighter and more modern Sony body. The Canon 28-105 USM was a faithful companion, so I can keep it thanks to this adaptor ring.

I bought this adapter to mount it on a Sony case (the 6700) and use the Tokina lens (ATX I) in manual mode.

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.

Great.
I have an old Tamron 500mm mirror lens that I bought in 1985. I had long thought it was now useless. But no! This adapter actually works so I can use it on my Canon EOS 400D camera. I just set the mode to aperture priority and reduce the exposure by one stop and then use as before. (I set the exposure to one stop under because the lens always seemed to work at a 5.6 aperture setting instead of the 8.0 it was meant to be).

So now I have my old lens.
