get a good adapter, cheap ones might not fit properly, might be loose, they might brake and you end up having some metal flakes in your camera, might not focus infinity(if they arent made to right measures) etc etc. those cheap af confirm adapters have that chip only clued in it, so it might drop off if you arent careful with it. i suggest getting a good adapter that you can program to get in right calibration if it shows focus slightly wrong. i dunno any adapter brands, but should be easy to google.
