Hi, I have a couple of old lenses ( pentax and zeiss primes ) I like to play with periodically and bought an m42 screw mount adaptor which i happily used with my 5Dmk2 and the lenses worked , now i have only 5dMk3s and i just get an error code when mounting with the adaptor , I can find any specific mounts for the 5D3 , anyone know of any known issue causing this. TIA
