I tried to find similar topic here, without success though. Ive just bought Canon M100 and wanted to use Artisans lens. I know that its possible to use adapter lenses if I enable releasing shutter without lens in Custom Functions submenu. The thing is... I don't have it. I can see only two main tabs (with camera and wrench icons). Appartenly Im not the only person with this problem (saw some people asking about the same thing under a youtube video), but no one was able to answer. I know that I shouldnt be in the green auto mode and thats what I did, but the Custom Fn icon still wont show. Any idea why?&nbsp;</P> Fri, 01 May 2020 13:02:45 GMT https://community.usa.canon.com/t5/EOS-DSLR-Mirrorless-Cameras/EOS-M100-missing-Custom-Functions-tab/m-p/304612#M71416 pampasowiec 2020-05-01T13:02:45Z https://community.usa.canon.com/t5/EOS-DSLR-Mirrorless-Cameras/EOS-M100-missing-Custom-Functions-tab/m-p/304619#M71417 <P>Generally you have to be in the advanced modes like P or M to "unlock" all of the options.</P> Fri, 01 May 2020 14:10:24 GMT https://community.usa.canon.com/t5/EOS-DSLR-Mirrorless-Cameras/EOS-M100-missing-Custom-Functions-tab/m-p/304619#M71417 kvbarkley 2020-05-01T14:10:24Z https://community.usa.canon.com/t5/EOS-DSLR-Mirrorless-Cameras/EOS-M100-missing-Custom-Functions-tab/m-p/304698#M71419 Okay I managed to find this option, thanks!
