t6i won't focus through viewfinder at times

chebo — Tue, 30 May 2017 09:52:29 GMT

Sometimes, the camera won't focus through the viewfinder. To get it to work, I either have to switch between LiveView and then switching back to focusing through the viewfinder or pressing the Depth Of Field Preview Button.

I've used 2 different lenses and even reset the camera settings, but the issue still continues.

It's a minor problem, but is there anyway to fix this?

Not the lenses because both do it. The DOF preview button might unstick an aperture blade but it isn't a lens thing.

Maybe be a dirty or damaged connection? Switching to live view and back and pressing the DOF button are not logically related that I can see so maybe they are working as the equivalent of banging on the camera to remedy a bad connection. Etween lens and camera.

Thinking of things involved in viewfinder focusing. See if mirror is dirty or if focus screen is dusty or misaligned/loose or scratched.

I can get it to manual focus by half pressing the shutter button too. It's under warranty, so I can just get it fixed.
