Speedlite 430EX II Compatibility with EOS R6 Mark II?

[mercator]

I am looking to buy a second hand flat (as I am normally outside in bright sunshine or in a studio with studio lights) and 430EX II have become very affordable. I was wondering if the 430EX II will work with the Mark II version of the Canon R6 - including TTL - and if the the Canon R6 Mark II's flash menu will work? Will I face any limitations?

Yes the 430EX II is fully compatible with your camera. It's fully compatible with the in camera flash menu. Note the IR AF Assist Beam IS INCOMPATIBLE with mirrorless cameras. The speedlite will switch to Intermittent Flash Firing (IFF) to assist the camera's AF system in low light. But depending on the ambient lighting. The camera body may emit an LED AF Assist Beam. The camera must to One Shot AF. The AF Assist Beam enabled in the camera and the speedlite.

Thanks, I have seen that page. I have also an old EX380 that works (but not with the built in menu) and I have also noticed that for other Rx models, some of the older flashes that are not mentioned actually work. That is why I am asking as the list does not seem to be complete. So, if anyone use the 430EX II or a 580EX (II) version, I'd be happy to hear what works and what not.

Only weather speedlites require an adapter. Old speedlites like the 380EX are partially compatible with the in camera flash menu. To set rear curtain sync, FEC & flash firing.

Would you by chance know if the the 580EX II would work as well? That number (580) is not listed at all on the R6 Mark II compatibility page. Thanks lot.

All weather sealed speedlites 580EX II, 600EX/ 600EX II-RT, & EL-1 require the AD-E1 hot shoe adapter. They are otherwise compatible. They are also fully compatible with the in camera flash menu. The original 580EX IS NOT COMPATIBLE with the in camera flash menu. All of Canon EX or EL model speedlites are compatible. Speedlites released prior to the 430EX II, 580EX II & the original 270EX. Are NOT COMPATIBLE with the in camera flash menu.

The AD-E1 hot shoe adapter is only required if I want to maintain the weather sealing of the flash, right... which would not matter as I do not intend to use in the rain?

Found the answer: https://insider.kelbyone.com/review-canon-multi-function-shoe-adapter-ad-e1/ only needed to retain weather sealing it seems.

No the speedlite won't fully slide in and lock into the hot shoe if its a model with weather sealing. My friend's mom owns the R6 Mark II and her husband owns the R7. The EL-1 won't fully slide in and lock into the hot shoe. The only thing that you would lose functionality wise would be the IR AF Assist Beam. The speedlite will switch to Intermittent Flash Firing (IFF) automatically. Even speedlites such as the EL-1 which has choice between IR and IFF. Will use IFF on the EOS R series. All that setting does if a color filter or flash diffuser is used and the speedlite is set to IFF. The camera body will emit an LED AF Assist Beam. The way how IFF works is the camera rapidly varies the voltage to the speedlite to control the brightness of AF Assist pre-fire.
