I need to use my Speedlite off-camera. The tutorials and and advice on YouTube shows photographers using the recent generation of wireless Speedlites and strobes.
* Is there a transmitter/receiver package that I can use for my 5D mkIII and Canon 580EX? I'd like to be able to trigger the camera from the strobe/receiver as well.
You can try the Yongnuo YN-622C-TX transmitter/YN-622C transceiver and Godox Xpro-C transmitter and X1R-C receiver, but neither combo is likely to give you full manual control over a 580EX. They're designed to work more with 580EX II-era and later gear. The 580EX's wireless communication capabilities (which is what these reverse engineered pieces of gear are faking) don't allow for power control other than TTL group ratios, really (sigh).
It wasn't until the Digic IV processor came in on the cameras and the 580EX II/430EX II were released that you got A-C group control in either all-M or all-TTL. The 580EX II is completely compatible with those triggers.
I can upgrade to the Godox wireless speedlite if it's necessary, but my 580EX was expensive and it still works.
I know the feeling. But back in the YN-622 days, I had to swap my 580EX for a 580EX II just to get my YN622 gear to work. Just me, but it's probably worth it to blow $130 on a TT685 II-C to take the place of your 580EX as an off-camera unit and keep the 580EX for on-camera use (still has better TTL accuracy/consistency, overheat protection, easier head rotation, etc.)
The TT685 II-C will also be a lot nicer/more convenient for off-camera use since you won't have to ever remember to pack a receiver and batteries for the receiver.
Having the transceiver built-in makes for faster/simpler/more robust setup and breakdown as well. The convenience of having that cannot be overstated. And every time you think a TT685 II-C is too expensive, just remember how much a 600EX II-RT costs.
