I have a Rebel T2i. When in manual modes, if I press the shutter half way it focuses, and if I press it all the way I get a click and I lose the viewfinder. I then have to press it again fully for it to snap back into place and take the picture.
In auto modes one full press takes the photo.
This just started happening and I have no idea why. A reset of camera settings didn't help.
Any Ideas? Anyone experience this before?
