Retains the shift amount for program shift
P.Fn-10
Normally, any program shift amount is canceled after you take the
picture. This Personal Function retains the program shift amount.
This function is useful when you want to shift the standard program
line so that priority is given to the shutter speed or to the aperture.
By shifting the program, you can change the shutter speed or aperture
and still retain the same exposure level. Under the same brightness, you
can shift the program line toward the right to set a faster shutter speed
and a larger aperture (lower f/number). Or you can shift the program line
toward the left to set a slower shutter speed and a smaller aperture
(higher f/number). P.Fn-10 retains the amount of program shift. Select
the appropriate amount of shift for the level of priority you want to give to
the shutter speed or aperture setting.

The program shift amount remains in effect until you set it back to
the standard program manually or replace the battery or press the
< CLEAR > button.
The shift amount is retained even after you change the lens.

giving priority to the drive speed
1D
During continuous shooting, shutter release-priority takes effect
instead of focus-priority.
Effective when it is more important to capture an image even though it
might be slightly out of focus.
Disables focus detection (search driving) by the
P.Fn-14
lens drive
Normally, when you press the shutter button halfway and focus
cannot be achieved, the lens is driven to search the correct focus.
This lens driving operation can be turned off.
When focus has been achieved once and refocusing fails, the
subsequent lens driving operation can result in grossly out of focus.
This subsequent lens driving operation is turned off. P.Fn-14 is
especially suited for super telephoto lenses.
If autofocusing is attempted while the lens is way out of focus, the
lens may stop operating. Focus manually until the subject outline
becomes discernable, then autofocus.
Disables the AF-assist beam from being emitted
P.Fn-15
This disables the external Speedlite's built-in AF-assist beam.
At a joint photo session, etc., this prevents the AF-assist beam's
pattern projected on the subject from being photographed by other
photographers.
