Ok, so I've gotten this twice in the past few weeks. Never had it before.
A removal of battery clears it. I've heard it's an electrical error.
Should I be concerned? Can't really afford the $200 just to have Canon look at it. Not under warranty, had the camera since 7D launched!
Is it possible it's a bug with the new firmware? I,m on 2.0.3, and I've also upgraded my 40mm ancake to 1.0.2. Haven't had time to test another lens combination, so who knows if it's something inherently wrong with hardware, software, or those as a combination of my gear, battery, etc.
It does go away after removing battery, so it's not really a deal breaker.
Just wondering if anyone else gets it with the new updates, or just ever, even with other bodies/lenses.
