    Summary Autofocus with AEL button on Phase One 645DF/DF+
    Problem How can I control the Autofocus with the AEL button on my Phase One DF/DF+ camera?
    Solution Autofocus on the Phase One DF/DF+ body can be driven with the AEL dial just
    above the rear dial.

    Set custom Function 9 to 1 (Swap function of AEL and AFL buttons) - see image below.
    NOTE: Camera must be in Custom Bank A, B, or C!

    Step 2:
    Change Custom function 12 to 1 (AFL to AF operation)

    The half press will still also control auto focus.
    You can lock the focus by holding down the AEL button while triggering.

    Step 3:
    You can also disable the Half Press function. To disable the Half Press function change Custom Function 10 to 2

    Workflow suggestion:
    1) Change CF 9,10 and 12 as shown above.
    2) To activate AF on the AEL button - leave CF bank A,B or C and select Exposure mode X,M,Tv,Av or P.
    3) Copy settings to C1,C2 or C3:
    Hold down +/- button and change Exposuremode dial to C1,C2 or C3. Once selected - release the +/- button.
    4) Make sure your lens is set to AF and the body is set to S or C

    Reset Custom Functions press the +/- button for 3-5 seconds. Small "beep" all custom functions is reset.
