    5d Manual Control & Turning OFF AGC

    I am shooting a film in 1920x1080 and am having a little difficulty.

    1) Using 5DM2, with Canon AF lenses
    2) Want to have full manual Aperture and ISO control
    3) When I select M I have no control over F stop
    4) When in Av (aperture) I have no control over ISO it always goes to auto ISO and ruins video
    5) In Tv I have no control over F stop or ISO (latter always goes to auto ISO)

    HELP ???

    Audio gain is controlled through the menus.

    I've never used anything but "M", and have always had manual control of shutter and iris.

    Does your lens have an iris ring on it? Manual iris lenses will negate iris control through the camera.

      Thanks Chris, I wished I did have manual iris rings but not I have all newer L series lenses. When I'm in M mode (manual) the gear controls the shutter speed (which I want kept at 1/50th for shooting 24p) the rotating dial controls nothing. How does one control these settings then short opening the INFO menu and changing the setting thusly?

        Make sure the ON/OFF switch is all the way up to the little line that enables the back dial. It sounds like you just have it in the ON position, which locks the back dial out.

          OK right you are. I always set it to the half way mark. Hmmmmm, always wondered why the two clicks? So, running in manual with the ON switch all the way on . . will this prevent the AUTO ISO ??

          I the back dial will now control F stop and the crank gear will now control shutter speed AND then ISO can ONLY be changed via selecting the ISO switch right?

            Back dial is aperture, top dial is shutter, and you can set ISO manually or set it to automatic. In Tv and Av, the camera goes back to auto ISO when using live view.

              This has resolved my issue. Thank you so kindly. I was selecting Av to control the F stop and accordingly it was setting the ISO to auto which was wrecking all my video. YOU have saved me Sacksnack. Thanks so kindly. :-)

              (BTW, just heading out the door for the second day of shooting. Thanks again!)
