The TTL auto flash system can also be used with Type-B camera set to Av (aperture-priority AE), Tv (shutter speed-priority AE) or M (manual).
- When you press the shutter button halfway, the shutter speed and aperture setting are displayed as in any AE mode.
- When the 380EX is used with a Type-B EOS camera, the FP flash switch does not function
- Using the 380EX in the depth-of-field AE mode obtains the same results as using it in the Program AE mode.
