When the camera’s depth-of-field preview button is pressed, the flash 
fires continuously for approx. 1 sec. This feature is called “modeling 
flash”. This is effective for checking shadow effects on the subject with 
the flash light and the lighting balance during wireless flash shooting 
(p.45, 71).

Modeling FlashN

 

To avoid degrading and damaging the flash head due to overheating, do 
not fire the modeling flash more than 20 times continuously. After firing it 
20 times continuously, allow a rest time for at least 10 min.

 

If the modeling flash is fired more than 20 times continuously, the safety 
function may activate and restrict flash firing. If this happens, allow a rest 
time for at least 20 to 30 min.

 

During Live View shooting, firing modeling flash (by operating the 
camera) is not possible.

 

Modeling flash (by operating the camera) is disabled when using the 
flash with EOS M3, EOS M2, EOS M, EOS Elan II/Elan II E/50/50E, EOS 
REBEL 2000/300, EOS REBEL G/500N, EOS REBEL K2/3000V, EOS 
REBEL XS N/REBEL G II/3000N/66, EOS IX, or EOS IX Lite/IX7. Set 
C.Fn-02 to 1 or 2 (p.83), and fire modeling flash using the test flash 
button.

During normal flash shooting or when using the flash as the master unit in 
radio transmission wireless shooting, you can fire the modeling flash with 
the test flash button (C.Fn-02/p.83).
