wireless 550EX in manual mode with 420EX
Hi,
Is it possible to set the 550EX in manual mode with a 420EX as a slave? I've tried the setup in E-TTL mode without any problem but when the 550EX is set to manual mode, the 420EX is not firing. Am I doing something wrong or the 420EX is not supported when the 550EX is in manual and I need another 550EX as slave? |
wireless 550EX in manual mode with 420EX
Hello Danny,
I have the same combination and have also found that it is not possible to use the 420EX as a wireless slave in the M or MULTI modes. The 420EX manual states that wireless operation only works for E-TTL (see pages 43 and 48). Before I would buy another 550EX ($$$), I would consider using neutral density filters over one of the flash units and/or flash distance adjustments to achieve a similar effect. I'm assuming that you want to use manual mode because you want to have a flash ratio greater than 8:1 (or 1:8). Good Luck! Dave "danny" wrote in message m...
