Ultimate Canon EF->M42 lens adapter

!!! The Pin Push version is used for lenses in which the aperture requires pushing the pin in order to close it, to screw the lens in properly, you should push the pin when it passes the protruding element of the adapter, you can use e.g. a toothpick, the shape of this element is specially designed to be easy to print, I did many tests and it was the best solution at the minimal cost of convenience!!!

Important: You should check and inspect the print before mounting to the camera, so that there are no unwanted fluff or traces, so that they do not damage the camera shutter.

I present the most refined version of the M42 analog lens adapter for Canon EOS cameras with an EF connector, whereby the camera connector is covered and protected against short circuit.

Thanks to this project you can use old lenses, there is a red dot attachment, a design that makes it easier to remove, one wing of the bayonet is shortened because otherwise the camera would block after raising the mirror before taking off, the aperture and focus ring, or rather their markings, are at the top as they should be, and not running away somewhere to the side.
