EOS M10 switches itself off
Wasn't that FD lens made in 1979?

My camera is acting weird and switching itself off when I attach and use an old FD lens (70-150 f/4.5) with the adapter. The last time this happened it emitter a series of beeping sounds and then switched off. This is weird because the camera is working fine with the kit lens and an FD 50mm lens with the same adapter. Do you guys have any idea what's happening and what I can do? Thanks in advance!
You are using a lens marketed in 1979 that was never designed for use on a digital camera. Incompatible lenses will usually trigger several beeps from the camera before it powers itself down. I mounted my camera to a telescope with no contacts and it did the same. I had to enable the menu setting that allows me to use the camera "without a lens attached". FD lenses also produce a slightly different focal length on Digital cameras and a lens with zoom (and moving parts) is likely to cause the camera distress when varying amounts o light hit the sensor without registering the aperture changes via the lens contacts. The Prime lens ought to work better.

I assume you are using them with Manual Focus selected on your camera menu? Since this lens is probably more than 20 years old, you might want to check the area that comes in contact with the camera's contacts where the mount is to see if it's producing a contact (though I'd doubt it).
