Other external ash units

Note the following when using a third-party ash unit mounted on the camera hot shoe:

• Using obsolete ash units that apply currents of more than about 24 V to the X-contact will

damage the camera.

• Connecting ash units with signal contacts that do not conform to our specications may

damage the camera.

• Set the Shooting mode to M, set the shutter speed to a value no higher than ash

synchronous speed, and set ISO sensitivity to a setting other than [AUTO].

• Flash control can only be performed by manually setting the ash to the ISO sensitivity

and aperture values selected with the camera. Flash brightness can be adjusted by

adjusting either ISO sensitivity or aperture.

• Use a ash with an angle of illumination suited to the lens. Angle of illumination is usually

expressed using 35-mm format equivalent focal lengths.
