Canon EOS 1D Mark III Additional Functions

C.Fn I-9: Select which exposure modes are available

I-9 — Choices are: Disable, Enable, Register

This function lets you decide what exposure modes are available from the Mode Selection button. By default, all the camera's shoot-

ing modes — Program, Aperture Priority, Shutter Priority, Bulb and Manual — are available. With this Custom Function you can

limit those to only ones you will use, such as Av and Manual, making selecting a desired exposure mode quicker. If you like, only

one mode can be checked-off on this function's list, meaning when Enabled, the camera is locked in that exposure mode and cannot

be changed unless C.Fn I-9 is first set to "Disable".

C.Fn I-10: Select which metering patterns are available

I-10 — Choices are: Disable, Enable, Register

Lets you choose what metering modes are available from the metering mode selection button, for metering ambient light.

By default, all patterns are available: Evaluative, Center-weighted average, Partial, and Spot. By using this Custom Function

you can "Register" or memorize only the metering modes you will utilize, such as Spot Metering and Evaluative Metering,

and use only those whenever "Enable" is selected. To go back to having all settings available, set C.Fn I-10 to "Disable".

C.Fn I-11: Lock-in a metering mode whenever using Manual exposure

I-11-0 — Uses metering mode set on camera

I-11-1 — Always uses Evaluative metering when camera set to manual

I-11-2 — Always uses Partial metering when camera set to manual

I-11-3 — Always uses Spot metering when camera set to manual

I-11-4 — Always uses Center-weighted average metering when camera set to manual

This function allows you to have the camera immediately switch the metering mode to one you've pre-selected whenever the

camera is set to the Manual exposure mode. A photographer who typically uses Evaluative metering with automatic exposure,

but who likes to use Spot metering for Manual exposures, can have the camera always apply Spot metering any time the Manual

mode is engaged. Note that except for C.Fn I-11-0, when you're in Manual exposure mode with any of C.Fn 11's options engaged,

you won't be able to change to a different metering pattern.

C.Fn I-12: Limit range of available shutter speeds

I-12 — Choices are: Disable, Enable, Register

With this Custom Function you set the highest and the lowest shutter speeds the camera will use. Regardless of shooting mode,

the camera will only use the range of shutter speeds you set — including the Av and P modes, where the camera chooses the

shutter speed. Speeds available in full-stop increments; slowest top speed is

C.Fn I-13: Limit range of available apertures

I-13 — Choices are: Disable, Enable, Register

With this Custom Function you set the range of f-stops the camera will use (in full-stop increments). Regardless of shooting mode,

the camera will only make available the selected apertures. This can be very useful with studio strobes, or in other instances where

you want to limit any aperture changes. Note that you can't lock-in only one single aperture — for example, you can set a max.

aperture of f/8 and a minimum of f/11, but you can't set both to f/11. As usual, you can immediately revert to the full range of

lens apertures by selecting "Disable".
