my fellow Canon mark3 users you may find this useful

I have just come back from a shoot today when my Canon mark 3 would not let me change the exposure compensation. The rear exposure compensation wheel turned ok but did not change the values.

I switched the camera off and took the battery out then put it back in and turned the camera on... presto all was well again.

Probably better to perform this operation well away from clients!

Hope this helps, all the best,

Pete

did you have the on/off button in the second on position?

Thats what I was thinking also. Always happens to me.

I know what you are thinking lads, but the camera was set to the second on position.

Cheers,

Pete
