Disables focus detection (search driving) by the lens drive
P.Fn-14
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.
Enables automatic shooting when focus is achieved at the
P.Fn-16
fixed point of focus while the shutter button is pressed fully
This takes the picture automatically when the subject comes to the preset focusing distance.
Focusing detection is performed using the selected AF point.
Set the lens focus mode switch to <MF> and focus manually at the desired point of focus.
Keep pressing the shutter button fully.
Using an accessory such as Remote Controller RS-80N3 which can lock the shutter button
relieves you from holding down the shutter button while you wait for the subject.
Because the camera remains on standby while the shutter button is fully pressed,
battery power is used up more quickly. For long periods of photography, use the DC
Coupler Kit supplied with the camera.
When this function is used in combination with a flash, the flash remains on standby
at full charge. Consequently, the flash batteries are used up more quickly. (The
Speedlite's SE mode is disabled.)
When you use a flash with this function, set the drive mode to single shooting. If you
select continuous shooting, the flash will be unable to charge in time for successive
shots and will not fire at full charge.
If you set the drive mode to continuous shooting, set the number of shots in P.Fn-20.
If you do not use P.Fn-20, once the camera focuses on the subject, continuous
shooting will continue until the capacity of the memory card is reached.
P.Fn-16 cannot be used with manual focus lenses or with lenses that are too slow to
be used with autofocusing.
Do not use this function when C.Fn-4-1/3 is set as shots will be taken regardless of
whether the image is in focus.
Using an accessory such as Remote Controller RS-80N3 which can lock the shutter
button is recommended.
Disables automatic AF point selection
P.Fn-17
When you select beyond the peripheral AF point, the selection stops there. It makes
selecting a peripheral AF point faster.
If C.Fn-11-2 has been set, you can switch to automatic AF point selection by pressing
the <
> button during autofocusing. For more details, refer to "Selecting the AF
Point" in the camera's Instruction Manual supplied with the camera.
If automatic AF point selection has been preset at [AF frame registration] setting, the
preset setting remains valid. For more details, refer to "Registering and Switching the
AF Point" in the camera's Instruction Manual supplied with the camera.
Enables automatic AF point selection when C.Fn-11-2 has
P.Fn-18
been set
Enables the standard horizonal AF point selection together with automatic AF point
selection with C.Fn-11-2.
Convenient when you want to use automatic AF point selection while C.Fn-11-2 has been
set.
If P.Fn-17 [Disables automatic AF point selection] has also been set, P.Fn-17 will
override P.Fn-18 to disable automatic AF point selection.
Sets the continuous shooting speed
P.Fn-19
In the list box, select the speed of continuous shots during continuous shooting.
By reducing the maximum continuous shooting speed, AI Servo AF continuous shooting can
be more stable.
With the EOS-1Ds Mark II and EOS-1Ds, only [Continuous Shooting] is displayed.
In AI Servo AF, it may not be possible to complete the selected speed of continuous
shots.
Limits the number of shots during continuous shooting
P.Fn-20
This enables you to enter the maximum number of shots to be exposed during continuous
shooting while the shutter button is pressed fully.
Convenient when you do not want to shoot an unwanted scene that follows.
