Can't user vintage lenses on EOS M50

[tempuser11293]

I am connecting a vintage EF lens to my EOS M50 using an EF to EF-M adapter. The lens is old and is completely manual with no electronics. Every time I try to take a photo it gives me error 01 because it cant communicate to the lens since theres nothing to communicate with. How do I disable this error warning? It's incredibly annoying.

There should be a menu setting that allows shutter actuation without lens attached.

John nailed it!

This is from memory since I sold my M50. Give this a shot to release shutter without lens attached

• Place the body in M mode to enable all the menus
• Select the menu button
• Go to the wrench icon
• Select setup
• Page 5
• Custom functions option
• Function 3 set shutter actuation without lens it to 'enable' 

Reverse to disable when you take the lens off or you can shutter the camera with the lens off by mistake.

I've enabled this setting and it still happens, could this still be happening because I am using an EF to EF-M adapter that does have electronic traces, but the vintage EF lens does not?

Did you press Set when to changed the setting to “ON”? A lens without contacts is exactly what the option is for.

Oops, I didn't, thanks for the catch. It's working now, thank you so much 🙂

Something's strange. Any and every Canon EF-mount (or EF-S) lens ever made is an autofocus and auto-exposure lens. Of course it has all the same electrical circuitry and contacts as current EF/EF-S lenses.

What exactly is the lens you have?

OP said EF lens. Not necessarily a Canon lens.
