Are there any other Yongnuo yn-565ex flash users here? I recently bought as an interim flash on impulse to help improve my macro photography (I’m planning on getting the Canon mt-24ex soon). The flash works great except it’s chewing through batteries. I’ll take 10 – 20 shots and the batteries are no longer capable of charging the flash. The flash just beeps and powers down. I’m currently using those large Energizer AA packs you get at Woolies. I can send back to China for repair but want to first confirm that this isn’t the expected behaviour.
