It allows you to attach C-mount lenses for security cameras or old 16mm cameras to a mirrorless Canon EOS M mount camera. It is a beautiful item that has only been tested a few times indoors. It comes with a compatible rear lens cap. Due to the image circle issue, vignetting may occur, but it can be used as a characteristic of the image, so it may create a good atmosphere when used in music videos, etc. Also, only lenses with a diameter of approximately 41mm or less can be attached. Lenses thicker than that cannot be attached. Also, some security lenses have a long rear section. In that case, there is a possibility that it may come into contact with the camera's shutter unit, so please check carefully before use. Vignetting may occur depending on the lens, as the image circle covered varies. Please be careful. Infinity focus is supported. The purchase price on Amazon was about 3000 yen.
