I own a Canon Speedlight 580 EX II that is no longer working reliably. I also own a GoDox External battery pack and this combo has proven to be very effective. Looking to replace the Canon either used or new but now wonder about the Bolt and Yongnuo brands. Are either an acceptable lower cost flash unit that should be considered?
I also own a Canon 420 EX Speedlight but it will not accept an external battery pack so I am considering selling it off and buying perhaps 2 of the Bolt or Yongnuo units and an additional cable to power the flash from the external battery.
Any thoughts?
Bob
