MR14-EX wireless usage

Been offered a MR14-EX at a price that I can't resist. But I would be more interested if I

could use this wirelessly with my my 420EX (I have looked at the Canon website and they

say that it works wirelessly with the 550EX (I assume with the 580EX also). I understand

that i might need to go with the ST-E2.

Any help here?

14Ex works fine as a wireless master & will control one or more 420ex's with full ratio control etc. You can group the 420s with the sides of the 14 as A+B or assign them to their own group (A+B)+C

Good luck

<P>

According to that table, the MR-14EX can act as wireless E-TTL

master in either Auto-power or Manual(fixed-)power mode.

However, the 420EX will only respond to Auto-power signals, and

will not respond to Manual-power control signals.
