problem with T2i

Yes, it happens on more than one lens.

This is not a bad pixel situation. It is dust, debris, smudge, etc.

Auto Sensor cleaning is enabled but does not remove problem.

Manual cleaning does not help also.

I'm learning about Dust Delete but that appears to be more of a cancellation effect done through digital software manipulation. I realize now that I need to get my sensor cleaned. The thing is, I'm pretty sure now that it came this way from the factory!!

Thanks for eliminating the mirror as part of the problem for me.
