Canon EOS M/50mm 1.8

[b.t.photography]

I have the Canon EOS M with the 50mm 1.8 lens. When I press the shutter button half way to autofocus, the shutter closes but doesn't reopen. When I press the button again, it opens. Everything works fine on manual focus and the autofocus works with my other lenses. Any help would be greatly appreciated.

I don't know anything about the EOS M, but it sounds like what happens when the shutter speed setting is set to bulb. Hope this helps.
