Small spot on my OVF

MojoMaker · 2022-06-16 07:09:39

Noticed a new and annoying black mark on my optical viewfinder view yesterday. Seems to be just through the OVF as live view and photos are unaffected - still annoying. I didn't want to pull apart the viewfinder mechanism just yet, let it be more sensitive than it looks. Anyone dealt with this before? Canon 90D.

Possibly just dust on your ground glass focusing screen.
A blower or lens brush should clear it away if that's the problem. As it's at the top of the mirrorbox, be careful not to damage the mirror mechanism when cleaning it.
