The exif info is in the photos. This is my coworkers Minolta Dimage Z5. There is a circular hard black shadow on the top left at 6mm and at the top left and right at 10mm. It seems like he only gets these shadows when the focal length is wide 6mm and 10mm. I'm not sure, but it seems to be catching part of the lens barrel. Nothing is in front of the lens and the cap is hanging way below the barrel.
Thanks for anyone who has some input!
