Originally posted by Photogoof I removed the lens, set the camera on B, hit the shutter button,
Put a fully charged battery in the camera.
Go to "Set-up" menu, hit the up arrow to go to the last item (Reset), up arrow again to the one above the last item (Sensor Cleaning), right arrow to dive into the sub-menu, up arrow to "Mirror up," OK to raise the mirror.
The mirror remains in up position until you turn the camera off (or battery runs out).
This is safer than using B. You don't want you finger slipping off the shutter release button while you're doing this.
Quote: then wiped off the sensor while the mirror was up.
What (fluid, applicator) did you use to wipe off the sensor?
Quote: I only hope this has taken care of the problem. Seems like it has.
I hope so too.
