As you can see in the attached photo, an inconsistent black shadow has appeared in several of my exposures. I have ruled out the camera strap, and the shutter does not stick.
This happens without flash, across multiple lenses. The shadow sometimes appears curved, coming into the center of the frame only, or diagonal.
Help! I don't want to risk ruining more photos.
Any ideas?
