Rear of Camera Controls

The rear of the camera should be familiar (in different ways) to both EOS-1V and EOS-D2000 (Kodak DCS 520) users, and that was Canon's intention. On the left we have a group of 'digital controls' surrounding the 2" LCD monitor, below this there's a status LCD which again shows information which pertains to the digital side of the camera. On the right is the familiar quick control dial (which can be disabled in record mode but is always active in display or menus), power switch and CF compartment release knob.

On the left side of camera rear (surrounding LCD monitor / LCD status panel):

On right side of camera rear:

Button / combination

AE Lock - lock exposure as it is currently metered, this allows you to then recompose the image and shoot.
Enter AF point select mode:
Main dial dial (top) used to select AF points horizontally, quick command dial (rear) used to select AF points vertically.
Quick control dial switch - enables or disabled quick control dial for shooting mode. When enabled the quick control dial can be used to quickly set exposure compensation. This switch has no effect in menu or playback modes.
Power camera on / off:
 • Speaker icon (camera beeps to confirm AF lock or manual focus accuracy)
 • On (normal powered on mode)
 • Off (camera will continue writing images out of buffer if there are any)

  • C.Fn 4 allows you reprogram the function of the shutter release and AE Lock buttons to various combinations of AF / AE Lock.

Vertical / Portrait hand grip

The EOS-1D has an integrated vertical hand grip which runs the length of the base of the camera. There are a number of controls repeated on the vertical grip (in addition to the shutter release): main dial, FEL button, AE Lock button, AF Assist button and the AF point selection button. These controls are normally disabled and can be enabled by turning the vertical grip activation switch (great name) to 'ON'.

Depth-of-field preview button

Around at the front of the camera beside the lens mount (hand grip side) is the EOS-1D's depth-of-field preview button. Press this with a small aperture selected (or metered) and the lens will 'stop down' to that aperture allowing you to preview the effective depth of field of the final shot.
