i Selecting the Drive Mode148 o: The approx. 6.0 shots/sec. maximum high-speed continuousshooting speed is achieved under the following conditions*: 1/500 sec. orfaster shutter speed, maximum aperture (varies depending on the lens),flicker reduction disabled, fully charged battery pack, and at roomtemperature (23°C / 73°F). The continuous shooting speed may becomeslower depending on the shutter speed, aperture, subject conditions,brightness, lens, flash use, temperature, power source, remainingbattery level, etc.* With the AF mode set to One-Shot AF and the Image Stabilizer turned offwhen using the following lenses: EF300mm f/4L IS USM, EF28-135mm f/3.5-5.6 IS USM, EF75-300mm f/4-5.6 IS USM, EF100-400mm f/4.5-5.6L ISUSM. The continuous shooting speed may become slower if the remainingbattery level is low or if you shoot under low-light conditions. In AI Servo AF operation, the continuous shooting speed may becomeslightly slower depending on the subject conditions and the lens used. If you set [z5: Anti-flicker shoot.] to [Enable] (p.185) and shoot undera flickering light source, the continuous shooting speed may decrease,the shooting interval may become irregular, or the release time lag maybecome longer. When internal memory becomes full during continuous shooting, thecontinuous shooting speed may drop off because shooting will betemporarily disabled. If you select [Smartphone] in [Bluetooth function] under[51: Wireless communication settings], or if pairing is not completeeven if you select [Remote], <Q> will be changed to <m> and remoteshooting with Wireless Remote Control BR-E1 or Remote ControllerRC-6 will not be possible.
