My Canon 7d starts to blink busy after taking three pictures in a row. The screen says busy and the red light is flashing.
Any ideas what causes this?
I've reformated the CF card and tried using other cards but the same problem happens.
I've reset the camera and cleared all the settings.
The only way to get the camera to work again is to take out the battery.
Thanks so much for writing in. I am sorry to see that your EOS 7D camera is hanging after taking about three pictures and displays a 'busy' message.
Under normal circumstances, we would want to reset the camera to resolve this error. I see that you have done some of the steps already. I would suggest cleaning the lens contacts with a soft microfiber cloth in addition to trying a different lens on the camera.
If you find it occurring with multiple lenses and multiple cards then we suggest sending the camera into the service center to evaluate this issue. You can set up a repair online through the link below. I apologize for any inconvenience that this may cause you.
