Title: Canon 580 and Quantum Battery Post by: marcfs on February 07, 2010, 05:52:16 PM Hi Bob,
Is the Canon 580 Flash compatible with the Quantum turbo battery? Also what might cause a 580 to not be able to go into E-TTL mode? The flash unit stays in TTL mode and high speed flash and compensation cannot be activated.

You can check compatibility on their website - http://www.qtm.com/?page=3110&qmode=c
I'm really no expert on the 580EX. Not being able to get E-TTL and only getting TTL would happen if the flash was mounted on an older film body for example. I'm not sure what could cause that if it's mounted on a DSLR. I think they all support E-TTL Title: Re: Canon 580 and Quantum Battery Post by: oldtool on February 08, 2010, 06:48:20 AM According to what I remember Canon sttates all EX flashes are E-TTL compatable. What camera are you using it on?
Title: Re: Canon 580 and Quantum Battery Post by: marcfs on February 08, 2010, 07:26:51 PM I'm using the 580 on a 7D. I also tried the 580 by itself and it would not go into E-TTL.
I took the flash into Canon today and will advise what they found and did. Marc Title: Re: Canon 580 and Quantum Battery Post by: marcfs on February 09, 2010, 11:46:01 AM Apparently key electrical components are being replaced. I Will find out more when I pick the unit up from service.
