Speedlite 580EX II EOS R8 Compatibility

[RichardinIdaho]

I have a Speedlite 580EXII and am planing on ordering a new Canon R8 camera. Will my flash work with the new camera or do I need to replace it with a newer model?

Thanks

The 580 EX II appears to not be compatible since it doesn't have ETTL II.

The specs for the EOS R8 mention this about the hot shoe:

"21-pin multi-function shoe equipped with the traditional 5-pin contact (X-sync, communication contact)"

And for compatible flashes, it mentions:

"E-TTL II with EX / EL series Speedlite, wireless multi-flash support"

So you'll want to pick up an older EX Speedlite with E-TTL II or any of the EL series speedlites.

Actually this is NOT CORRECT. Canon introduced E-TTL II in 2004 with the EOS 1D Mark II. The 580EX II was released in 2008. So this speedlite already supports it. Also E-TTL II is implemented in the camera body not the speedlite. So the speedlite is already compatible. Along with ALL of Canon's EX or EL speedlites. Also Canon's documentation of the 580EX II also states the speedlite supports E-TTL II. The speedlite is also FULLY compatible with the external speedlite control menu. The IR AF Assist Beam IS NOT COMPATIBLE with ANY mirrorless camera. The speedlite will fire an Intermittent AF Assist Beam/ (Intermittent Flashes) instead. The AD-E1 adapter is required for the 580EX II because the speedlite has weather sealing other speedlites WITHOUT weather sealing don't require it.

My 580EXii fully operates with no issues on my R6ii. 

R6ii has the same multifunction shoe as R8.

The only thing is no weather sealing.

I bought the adapter Incase I need weather sealing.

Then ended up getting EL5 for R6ii.

580EXii will remain in 5Dii.
