Offered here is a Shoten Adapter for a Canon EF mount lens to a EOS Canon R or RF mount.  It is used but well taken care of. Tye glass is clean and nit scratched or foggy. It has AF and Image Stabilization features. It functions great, as it is supposed to. The two lens caps are included. Thus one has served me well,  ut I have since upgraded. Thanks for looking and please contact me with any questions.
