I’m using a reverse lens adapter for macro photography on a Canon EOS M3. Because the lens contacts aren’t connected, the camera won’t fire the shutter. Is there a menu setting to allow shutter release when no electronic lens is detected?

You should be able to do it. Open the menu and go to the C.Fn tab. Look for "Release shutter w/o lens" and set it to "Enable". Detailed in the manual on page 186.

Yes. On the Canon EOS M3, enable the custom function for shooting without lens communication:

Menu → C.Fn tab → “Release shutter w/o lens” → Enable

This allows the camera to fire even when the lens contacts aren’t connected, such as with a reverse adapter or fully manual adapted lens. If you need the exact menu reference, it’s also listed in the camera manual.
