Can 600EX-RT trigger a 580EX II?

Hope this is a simple question, but so far I can't be sure I've found the correct answer.

I know the 580EX II is triggered optically and the 600EX-Rt uses radio control, so (1) can the 600EX-RT still trigger the 580EX II when the 580 is set to a specific channel/group, and (2) could the 580EX II trigger the 600EX-RT?

I think the 600 can optically trigger the 580 but will it work channel specific?

Or do I need to think about selling the 580 and getting two 600's?

Thanks

Yes, the 600EX-RT can be used an a Canon optical master and fire Canon optical slaves.


I use manual exposure settings on the copy machine

^^^ It can also be an optical slave. i.e. in the optical multiflash scheme its a 580EXII with extended zoom range. :-)

Just to be sure, setting channel/group info in the 600EX-Rt will correspond to channel/group, power, etc. info in the 580EX II?

Thanks - didn't want to invest before I knew this answer.


As a side question, do either of you know of a good bounce defuser and will it also work straight ahead, too, so it doesn't have to be constantly removed from the camera body?

Yes, when set to optical communication mode, a 600 EX-RT will mimic everything a 580 EX II can do. It then adds a few goodies, which can be used with optical mode as well.

The big change is of course when using radio mode, but then it's not compatible with any 580 EX II, nor any other old Canon flash.

Just a follow-up - Based on what you said, if the 600 EX-RT is in optical mode, can an older STE-2 then control the 600 and 580 together? And, I'm assuming if yes, then its the more restrictive "line of sight" mode that I'm used to with my current STE-2/580EX II combination - just adding the 600 as a second unit.

That's correct. In optical mode the 600 EX-RT is very similar to a 580 EX II.
