I'm owner of a Canon EOS 40D
After buying a compact flash "iPro" 8 GB (cheap, but no copied in China), I'd suffered some problems.
First, suddendly it was unable to show some pictures. "Can't read this picture" appeared on the screen.
Second. After a photo session, I've forgotten to switch off the camera and the next day, when I was trying to see the pictures, nothing appear...only a black screen. No pictures.
On the top right corner, the serial photo 100-9xxx and in the left upper corner, the shutter speed and the aperture used during the session with differents values (read "normal values", no long expositions).
Somebody has had this problems ?.
In my humble opinion, the problem was in the cheap CF memory card
Note, this unit (gear) has a new "reflex box" due to "error 99" wich appear this summer.
Can anyone help me?.
Sorry for my (bad) english.
