■Approximate effective flash range in P-TTL Auto flash
(Unit: m)
* You can check the approximate range of distances within which the flash unit can adjust the flash output (and the appropriate exposure is
available) based on the combination of the ISO sensitivity setting on the camera and the aperture value from the above table when the mode
dial is set to (AUTO). (The values in "Wide Panel" line indicate the range when the wide-angle panel is used.) Note that the minimum range
that will give correct exposure is 0.7 meters.
