I have an 420EX and I can say I'm quite happy with it.
But I have another flash, an old (but very good condition) Yashica AF flash which I can use it on my camera with full manual setting, minus AF assist beam. It's about 3 volt so it's safe.
I want to use it as a 'slave' triggered by 420ex (only for fun, to learn manual lighting setup), but it always uses preflash since it's a fulltime E-TTL, without manual setting.
With optical trigger, the second flash would be fooled by preflash and not recharged in split second at the real shot.
I have tried to tape the hotshoe's left-front connector, it disables E-TTL but the flash fires at full power and everything is washed out.
So the non e-TTL is not an option since there's no manual power setting like in 430EX.
I searched around and found a trigger that won't fire at preflash.
Does anyone know it's reliable enough?
If there's no workaround for this,maybe I have to dump this flash and use single 420EX anyway
Thanks.
