Apparently my 3 year old Canon EOS 550D is fed up with my style of photography and decided to explore abstract arts instead. All it shows on the LCD and stores on the SD card is this:
When I attempt to gather 'Dust Delete Data', it keeps saying 'Could not obtain the data. Try again." When I switch to movie mode, I get Err 70:
Shooting is not possible due to an error.
Turn the camera off and on again or re-install the battery.
What is causing this weird pattern? Is there anything I can try to fix or further diagnose the problem?
After turning it on and off again numerous times, the sensor suddenly functions normally again. However, I am still interested in an explanation of the above pattern.
