Selecting the center focus point with a Canon in a Subal housing

This may be an incredibly stupid question but I cant work it out. This is for all Canon users that have their cameras housed in Subal housings. How do I access the center focus point with Multi-controller dial system on the Subal housings? I can access all the peripheral focus points with this dial but I can not seem to bring it back to the center point. I can get there using the quick control dial on the back but then changing the aperture becomes a mission.

Thanks

Which body do you have Mark? On the 7D you hit the Multifunction display/ magnify button, (upper right corner) then the M-Fn button to select the spot AF or zone AF etc. Either the Main dial or the rear quick contol dial will select the AF point

The the 40D/50D you press the Multi finction display then use the main dial(behind the shutter) or the rear dial to choose the AF mode / point. If you keep turning the dial you get all the choices. You can hit the MF display button to get out of it or do what I do and just half depress the shutter and your rear dial is back to aperture control.

Hope that helps,

Steve

Thanks Steve

I am using a 5DMk2 and had my camera set up to access the Multi-controller directly with the cameras custom function. I have returned this function to the default and it works much better for me in the housing.
