i Selecting the Drive Mode
The continuous shooting speed for < o > high-speed continuous
shooting may become slower depending on the power source type,
battery level, temperature, ISO speed, flicker reduction, shutter speed,
aperture, subject’s conditions, brightness, lens, flash use, shooting
function settings, etc.
As shown on the table on the preceding page, with H1 (equivalent to ISO
102400) or higher ISO speeds (ISO 32000 or higher if the camera’s
internal temperature is low), the maximum continuous shooting speed
will become slower.
When ISO Auto is set (p.165) or when safety shift (p.426) automatically
changes the ISO speed, the maximum continuous shooting speed will be
controlled according to the conditions shown in the table on the
preceding page.
With [ z 3: Anti-flicker shoot. ] set to [ Enable ] (p.198), shooting under
flickering light will decrease the maximum continuous shooting speed.
Also, the continuous shooting may become irregular and the time lag
until the shot is taken may become longer.
With AI Servo AF, the maximum continuous shooting speed may become
slower depending on the subject’s conditions and the lens used.
The maximum continuous shooting speed may decrease if the battery
level is lower than 50% or if you shoot under low-light conditions.
If the camera’s internal temperature is high and the drive mode icon is
blinking, the maximum continuous shooting speed will become slower to
prevent internal damage to the camera. If you keep shooting and the
camera’s internal temperature keeps increasing, the maximum
continuous shooting speed will greatly decrease or the camera will stop
shooting until the internal temperature goes down. If the drive mode icon
is blinking, set the power switch to <
2 > and stop shooting for a while.
In low temperatures and the battery becomes extremely cold, the
maximum continuous shooting speed may decrease to approx. 10.0 fps.
If < 6 >, < 6o >, or < 6p > is set, the time lag from when you press
the shutter button completely until the picture is taken will be longer than
normal.
When internal memory becomes full during continuous shooting, the
continuous shooting speed may drop off because shooting will be
temporarily disabled (p.161).
