Troubleshooting Guide AF speed changes depending on lenses used. During Live View shooting and movie shooting, the AF control method (phase-difference detection with the image sensor or contrast detection) switches automatically depending on the lens type and function used such as magnified view. The AF speed may therefore change greatly and focusing may take longer. Focusing takes a long time. If FlexiZone - Multi is set, it may take longer to focus on the subject depending on the shooting conditions. Use FlexiZone - Single or focus manually. If the movie recording size is set to L 8(59.94 fps) or 7(50.00 fps), contrast detection will be used for the AF control. The continuous shooting speed is slow. Depending on the shutter speed, aperture, subject conditions, brightness, etc., the continuous shooting speed may become slower (p.142). When EOS iTR AF is operating (p.128), maximum continuous shooting speed set with will be approx. 9.5 shots/sec. Also, under low-light conditions, the continuous shooting speed may decrease. If [Anti-flicker shoot.] is set to [Enable] and you shoot under flickering light, the continuous shooting speed may become slightly slower, or the continuous shooting interval may become irregular. Also, the time lag until shutter release may be slightly longer than usual (p.185). The maximum burst during continuous shooting is lower. If you shoot something that has fine detail such as a field of grass, the file size will be larger, and the actual maximum burst may be lower than the number mentioned on page 151. 499
