Adapter is solid and well made. I love the button on the back for removing the ring off a lens. It's much easier to use than the metal tab some other adapters have. The only small inconvenience is not being able to switch lenses on the camera without having to remove the adapter as well, but the button allows for switching lenses relatively quickly without much fiddling.

This is a great mount for lenses that have a built-in manual aperture adjustment, not the best for AF lenses.

The adapter fits perfectly without wobbling and now connects my second-hand 500 mm mirror telephoto lens from Tokina with the current Canon cameras with EF connection. The mechanical quality of the product is really very good. Please note: An autofocus function is not transferred under any circumstances.

The thing is solid, I use 5D with helios attached to it, I can use it without any problems, but the infrastructure did not come, it is dedicated to portraits.

The old lens of the M42 mount was available and the state of the lens was also good, so I wanted to use it and I arranged this time.Depending on the lens, Fujinon lenses that support open photometry can not be used because there is a protrusion on the back of the aperture ring.

It works as stated. It's good to read the instructions before installing, in order to remove.
