• Select the desired AF point and press the shutter button halfway while manual focusing. When focus is achieved, the selected AF point will flash and the focus confirmation light will light.

•When the AF point is selected automatically and the center AF point achieves focus, it will flash and the focus confirmation light will light.

•With USM (Ultrasonic Motor) lenses (except those not having a distance scale), you can use the focusing ring to fine focus after focus is achieved in the One-Shot AF mode (full-time manual focusing).

For USM lenses with an electronic focusing ring (such as the EF 200mm f/1.8L USM), Custom Function C.Fn-07 can require the lens focus mode switch to be set to <> (or <>) before manual focus is enabled. (→p.134)
