I have a Rebel T3. My problem is that I have permanent nerve damage that affects sensitivity in the right hand, so I can never tell clearly whether or not my finger is on the release button. More often than not it has slid off, so I have to stop, reposition my finger and start again.
On Amazon there are lots of concave buttons, but they all have screw threads on the bottom but the T3 has a flush, smooth convex button, with no screw hole. (I remember my old film cameras had a threaded hole in the shutter release button, into which one screwed in a cable for remote shutter release.)
Sughgestions? Sticky buttons perhaps? 100 grit sandpaper to roughen it up? Where do I begin to look?
