Canon 40d shutter button repair.
Fix it by your self.
Yer ive heard of the issue with the 40d shutter button before and it turned out to be dirt under or within the button compartment.

As i said i would do a search about it 20ds seem to have this problem.
My 40d shutter failed after 16 700 actuations.
This replacement is moderately to highly involved and should be allotted at least one hour.
