<< I have tried using my 420EX on camera (1Ds) to fire off both my Bowens Quad pack and my elinchrom monoblocs without success. The packs fire but the sync is wronf and the flash doesn't show up in the shot even at slower shutter speeds. >> John,
Could it be that the 420EX is firing in E-TTL mode? In which case the preflash will trigger the main flash tubes. I set my 550EX to Manual to avoid this problem. If the 420EX does not have a manual mode, it may be worth getting an old small flash unit as a wireless trigger.
