' Radio Transmission Wireless Flash Shooting

When performing radio transmission wireless flash shooting, function 
restrictions may apply, depending on the camera used.

 

When using the flash with a camera such as the EOS-1D X, you can 
shoot without any restrictions on the flash mode and flash sync 
speed, etc.

* Although EOS REBEL T5/1200D was released after 2012, restrictions on 

functions are the same as with EOS DIGITAL cameras released up to 2011. 
(See the following explanation for details.)

 

When using the flash with the cameras listed below, radio 
transmission wireless shooting using E-TTL autoflash is not 
possible. Shoot with the manual flash (p.62) or optical transmission 
wireless slave function (p.71).

EOS-1Ds, EOS-1D, EOS-1V, EOS-3, EOS Elan II/Elan II E/50/50E, EOS 
REBEL 2000/300, EOS REBEL G/500N, EOS REBEL XS N/REBEL G II/
3000N/66, EOS IX, EOS IX Lite/IX7

Also, when using the flash with an EOS DIGITAL camera or EOS 
film camera released up to 2011, the following restrictions apply.
1. The flash sync speed is 1 stop slower.

Check the flash sync speed (X = 1/*** sec.) of your camera and 
shoot with a shutter speed up to 1 stop slower than the flash sync 
speed (Example: When X = 1/250 sec., radio transmission 
wireless shooting is possible from 1/125 sec. to 30 sec.).
When you set the shutter speed 1 stop slower than the flash sync 
speed, the <k> warning icon will disappear.

2. High-speed sync shooting is not possible.
3. Group flash is not possible
