How focus lock on the EOS 40D.

Solution

After achieving focus, you can lock the focus on a subject and recompose the shot. This is called focus lock. Focus lock works only in the One-Shot AF mode.


- 1. Set the Mode Dial to a Creative Zone mode.
- 2. Select the desired AF point.
3. Focus the subject
  • Move the AF point over the subject and press the shutter button halfway.
4. Keep pressing the shutter button halfway and recompose the picture as desired.
- 5. Take the picture.
If the AF mode is AI Servo AF (or AI Focus AF set to Servo mode), focus lock will not work.
Focus lock is also possible in Basic Zone modes (except <>). In this case, start from step 3.
