On my 10-22mm EF-S the button to switch between manual and autofocus is stuck, jammed, can't move it. Luckily, it's on autofocus. I rarely need manual, but it would be nice to move the button. Has anyone else had this problem? Suggestions? The button is so tiny and smooth it's hard to get a grip on it. Hate to smash it with anything and would hate to jam it in manual mode. Ideas?
Thanks
