Canon MR-14EX - Manual (Page 83)

Flash Distance Range
The MT-24EX’s effective flash distance range greatly depends on the
position and angle of the flash heads. For best results, point the flash
heads directly at the subject and use FE lock p.30) and modeling flash
(-> p.29, 55).
When the correct flash exposure is obtained, the flash exposure
confirmation lamp lights (-> p.16).
o If you are shooting at around the closest focusing distance, stop down the
aperture by about three stops (from max. aperture at ISO 100).
QSCustom Functions
The MT-24EX has nine Custom Functions from C.Fn-1 to C.Fn-9. C.Fn-1 to
C.Fn-7 are the same as the MR-14EX’s p.65), and C.Fn-8 and C.Fn-9
are described below.

C.Fn-9: Setting this to “1” enables you to turn on/off the focusing lamp by double-clicking
the shutter button halfway. This is convenient when both of your hands are busy.
The clicking interval differs slightly depending on the EOS camera.
(The clicking interval cannot be adjusted.)
O • C.Fn-9-1 does not work with the EOS D30.
•With the EOS Elan ll/Elan II E/50/50 E, C.Fn-9-1 will work only while the pilot
lamp is on.
•Turning the focusing lamp on and off too often will drain the batteries faster.
• If C.Fn-9-1 has been set, note that pressing the shutter button halfway too often
during autofocusing may inadvertently turn on/off the focusing lamp instead.
This also applies to the AE lock button and depth-of-fleld preview button.
Pressing any of these buttons twice in rapid succession or one button after
another may turn the focusing lamp on or off.
