The PowerShot G3 makes it possible to use the
MT-24EX* Macro Twin Lite for macro photography

MR-14EX Macro Ring Lite) developed for use with
EOS cameras. This flash makes delicate light
distribution possible in the macro mode.

- Various Speedlite accessories (such as transmitters and camera shoe cord 2) can be used
The PowerShot G3 can utilize accessories

It also supports the ST-E2 Speedlite
Transmitter.

*1: Full exposure is set when the PS G1 is in the manual shooting mode.
In the manual shooting mode on the PS G2 and PS G3, the default setting is 2 stops down from full
exposure, but this value can be set in one-third stop intervals over a range of ±2 stops using the camera
user interface.
Using the flash user interface, the flash strength can be set in one-third stop intervals over a range of
±3 stops in the same way.
However, +2 stops or greater reaches full exposure.
*2: When using of ST-E2 both the PS G3 and Speed-lite are set in manual mode, the flash doesn’t flash.
Items marked with X in the table above may appear to work, but there is no guarantee that the specified
exposure accuracy will be obtained.
