- In still photo shooting, regardless of the AF area setting when Servo AF is used with [Subject Tracking: On] set, AF is performed using [Whole area AF]. [Subject Tracking: Off] should be set if users wish AF to be performed at their preferred position when Aervo AF is used, as on previous models.

Shutter

Type
(1) Mechanical

(2) Electronic 1st-Curtain

(3) Electronic Shutter (1st and 2nd curtain - silent*)

- When set to [Electronic], the camera makes no mechanical shutter sound. Shutter volume during Electronic Shutter is adjustable in 5 user-defined steps, plus silent - Set-up Menu #2 > Volume. Electronic Shutter sound is also disabled when Beep is set to Disable - Set-up Menu #2 > Beep. Note that the camera may make sounds other than the shutter release sound, such as sounds for aperture adjustment or the lens focus drive, or beeps. Moreover, using long exposure noise reduction with shutter speeds of 1 sec. or longer involved mechanical shutter, which producers a mechanical sound.

- Bands of light may be displayed and captured images may be affected by light and dark banding when shooting under fluorescent lighting or other flickering light sources with the camera set to [Anti-flicker shoot: Disable]

- The following settings are available when [Electronic] is set:

- Drive mode selection (H+ / H / L), shooting with an external flash unit, anti-flicker shooting, shutter speed (no low-speed restrictions), long exposure noise reduction, AEB, Multi Shot Noise Reduction, HDR Shooting (HDR PQ), HDR mode, multiple exposures.

-M or Tv modes, with Electronic Shutter: user-set shutter speeds extend to 1/64,000 sec. maximum. (Set in full-step increments from 1/8000 to 1/64000).

Shutter Speeds

Mechanical Shutter / Electronic 1st-curtain	1/8000 to 30 sec. (in 1/3- or 1/2-stop increments) bulb
Electronic Shutter	1/64000 sec., 1/32000 sec., 1/16000 sec., 1/12800 sec., 1/10000 sec., 1/8000 sec. to 30 sec. (in 1/3- or 1/2-stop incremements), bulb

-In electronic shutter shooting, shutter speeds of 1/10000 sec. or faster are only available in Tv or M mode (up to 1/8000 sec. in Fv, P, or Av mode).
-Adjustments by the camera when the shutter speed is set to 1/64000 or 1/32000 sec. in electronic shutter shooting may involve the aperture value or ISO speed in some shooting conditions, because shutter speed cannot be controlled in 1/3- or 1/2-stop increments.
-If HDR mode, Focus bracketing, Hi-speed sync, or Same exposure for new aperture is set, max shutter speed limit will be 1/8000 sec.

1. AE, flash metering, and white balance are fixed after the first frame when using High-speed continuous shooting+, flash, and mechanical/electronic first-curtain shutter.
2. When set to [High-speed continuous shooting+], the continuous shooting speed in flash photography (with flash metering between shots) is up to approx. 15 shots/sec. Flash metering between shots is not supported with mechanical shutter or electronic first-curtain. Without flash meter between shots, the continuous shooting speed with flash is up to approx. 20 shots/sec. with the elctronic shutter. Note that the maximum of approx. 15 shots/sec. with the electronic shutter is only available when using EL or EX Speedlites released in or after 2007 (except 430EX II, 90EX, 320EX or 580 EXII)
3. The continuous shooting speed in anti-flicker shooting drops to a maximum of approx. 5.4 shots/sec. with mechanical shutter and a maximum of approx. 10 shots/sec. for electronic first-curtain. With electronic shutter, if flicker frequency is 60 Hz, max continuous speed will be approx. 24 shots/sec. and if flicker frequency is 50Hz, max continuous speed will be spprox. 20 shots/sec.
4. The continuous shooting speed in flash photography (with flash metering between shots) drops to a maximum of approx. 4.8 shots/sec. with mechanical shutter and a maximum of approx. 6.8 shots/sec. for electronic first-curtain.
5. The continuous shooting speed in flash photography (with flash metering between shots) drops to a maximum of approx. 5.4 shots/sec. with mechanical shutter and a maximum of approx. 6.6 shots/sec. for electronic first-curtain.

Video Recording Times

Maximum durations of shooting until recording stops in respective modes by heat. (Max. approx.)¹

1. Confirmed with a 325GB card based on Canon's testing standard
2. The maximum duration of shooting may be shorter under some circumstances even if recording begins from a "cold start", due to a rise in temperature inside the camera caused by pre-shooting camera setting operations or by prolonged use of the Live View mode. When the card is full, movie recording stops automatically. In this case, duration time when you erase the data and restart shooting.
3. When set to "Auto power off temperature: High", the card can get very hot and may even cause burns when being removed from the card slot.
4. Durations of shooting may not change between the [Standard] and [High] settings, depending on types of cards used.
