I'm using the Godox S2 bracket,, not sure if the EL5 would fit the S1 bracket. Bowens mount beauty dish,, Although I'm wishing I picked up an Archer Speedbox. Let me know if anyone has tried the Archer Speedbox.
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.
