Title: Help: EOSM Aperture/Exposure button
Post by: garry23 on November 03, 2017, 07:36:31 PM
I've pulled my hair out all afternoon.

I have two EOSMs and one, all of a sudden, exhibited a strange behavior: the Aperture/Exposure button stopped functioning, ie I could not use it as a right toggle in menus (ML or Canon) and could not toggle between aperture and shutter.

I've tried different lens: no difference.

I've removed ML, via firmware reset: no difference.

Has anyone else had a similar problem and fixed it!

Cheers

Garry

Looks like HW issue. Mine sometimes skips pushes. Works one time on every second or third push. Sometimes ok.

@madz

That's what I'm fearing is wrong.

whole back panel with buttons can be replaced, but it's quite expensive, something like quarter of this camera budget:

other option is this:
