(2) Dust Delete Data acquisition and appending

  • The coordinates of the dust adhering to the low-pass filter are detected by a test shot and appended to subsequent images.

  • The dust coordinate data appended to the image is used by the EOS Canon Digital Professional Software (v. 4.14 and higher) to automatically erase the dust spots.

  • Not available with EF-S lenses, in cropped shooting or multi-exposure shooting.

    Zone AF area) in the center of the screen.

  • 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.

    can be moved.)

  • button can be used to activate and deactivate eye control.

  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. (An electronic shutter sound can be configured in [Beep] and [Volume: Shutter volume]). 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 Reduc- tion, HDR Shooting (HDR PQ), HDR mode, multiple exposures

Shutter Speeds

  • 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 elec-

    tronic shutter shooting may involve the aperture value or ISO speed in some shooting conditions, because exposure 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.

Shutter Lag Time

*Based on Canon testing standards.

*The shutter-release time lag is longer in flash photography with anti-flicker shooting.

*1: Using RF or EF lenses (except EF-S lenses)

*2: At maximum aperture.

*3: Using EF-S lenses and electronic 1st-curtain: approx. 45 ms.
