Godox issues with the R5 are only if TTL and HSS are used at the same time, right?

I don't use TTL so just want to make sure I am understanding the issues I have seen reported in some places. It seems that it is only when using TTL and HSS together but not, like in my case, when I use HSS only.
Thank you!

Yes, that's the use case.  It does not have the flash intensity set correctly, or the preflash measurement is messed up.  HSS with manual level is OK.  TTL with x-sync is fine as well.

If you do -3 on exposure compensation, it exposes properly. But you obviously can't compensate past a certain point and you're limited in what you can do, to some extent.

Re: Godox issues with the R5 are only if TTL and HSS are used at the same time, right?

I've had no glaring issues with the V1. I simply set it to -7 and go in TTL. Thus far it's rendered perfectly fine results. I don't use HSS. The battery lasts forever on a charge which I'm spoiled on, no more AA's. Love the balance it provides.

I emailed Adorama about this issue. Godox is aware of the issue and have not released a firmware update yet. Apparently it has too do with the pre-flash in TTL with HSS. The pre-flash doesn't sync correctly with the R5 so it just pops at full power since it doesn't see any light from the preflash. So you can't really say just FEC -3 or whatever will work. It will all depend on how much full power will affect your shot.

And from my experience is this is only an issue with off camera flash, not when mounted to the camera.

I can say that because it works. For me with the R2 Pro II the flash doesn't go full power, it flashes +3. If I do -3 it exposes perfectly well. I shoot manual anyway so this issues doesn't affect me but there's a workaround as long as you don't need negative compensation.

I use a V1 Godox. When I got it I worked with it and Godox's top remote unit as well as on the camera. I don't do HSS so let me qualify that. I found by setting it to -7 with TTL it was dead on every time. So I'm a happy camper unlike those that are having issues here. I suppose with many products they don't meet the expectations or needs of some. In my case as you expressed it does a fine job and I wouldn't go with any other flash in it's place. I'm on a R5 as well.

Re: Godox issues with the R5 are only if TTL and HSS are used at the same time, right?

There are a lot of people who are missing the simple  point when this issue is brought up.

The R bodies will not properly TTL and HSS simultaneously at the same time as they default to full power. This issue is compounded by the inability to bracket in any way while using strobes in the R bodies.

Sure, I shoot in manual nearly all the time too, but when I'm on location outdoors and the sun goes from 1/8000 sec to 3 stops brighter and then back again because of clouds within a matter of seconds,it helps out to be able to use both simultaneously when there's a small crew of a half dozen people with me standing around wondering why I'm fiddling around and not shooting. People constantly mentioning how a speed light mounted on top on the camera works fine are confusing the issue and hurting the very reason we post this issue, which is to get Canon to fix the firmware

Not sure Canon is liable for breaking an unlicensed proprietary protocol. Godox needs figure out the issue and have a workaround IMO. Why can't the camera industry have a standard here is just bad for consumers.

I think the specific use case (remote + TTL + HSS) is more unique. Most will never have used such a combo, but I use it for sports photography. I think event photographers won't have the time to measure their shots either.

Re: Godox issues with the R5 are only if TTL and HSS are used at the same time, right?

Rather old thread but I just got confirmation from Godox that HSS thru wireless transmitter ( XProC ) doesn't work with the R5 period. Neither in TTL or manual mode. They claim it's a Canon issue.

Thank you!

Also, just to clarify. I use the Godox X2T Transmitter in HSS mode (and Manual) with the R5 and R6. No problems.

Good for you!

This is what Godox told me:

"Thanks for contacting Godox,we are sorry for the inconvenience.Both X1T and X2T are also can not work with R5 in Hss mode,really sorry for the inconvenience."

That has been my experience. I don't use HSS so no issues whatsoever with my V1. It's a superb flash with power to spare for a days shooting. Plenty bright as well. What a bargain and well built as well.

Indeed it is! I find HSS to be an invaluable tool for everything from portraiture to events to birding to shooting macros!

The Godox X2T-C paired with my Godox V860iii-C makes for a very powerful, versatile, and inexpensive combination. I highly recommend it!

This is what Godox told me:

"Thanks for contacting Godox,we are sorry for the inconvenience.Both X1T and X2T are also can not work with R5 in Hss mode,really sorry for the inconvenience."

Manufacturers put out a lot of generic blanket statements. Fortunately you have the Forum here to use as an additional resource.

Happy shooting!

ps. As has been noted in a number of threads thus far, the combination of HSS and TTL does NOT work together with the Godox radios (and R5/R6). You can do one or the other.

That's great that you don't use HSS.Thanks for sharing that.

However,the thread is regarding HSS simultaneously used with TTL.

Sounds like Godox engineers had already given up.  That's too bad, but at least it brings a closure to this issue.

Re: Godox issues with the R5 are only if TTL and HSS are used at the same time, right?

I know this is and old thread but was hoping it's still alive. I have been using the V1-c with an R5 and this issue explains a lot, as I use HSS regularly. I was just putting the inconsistent results down to the flash itself. My question, if anyone here knows, does the V860III have the same issues with the R5 and HSS? I am thinking of getting another flash that I can use in the situations I need TTL & HSS. Thanks

I think the issue was in the trigger, not in the specific flash. And the new version of the trigger still has some issues, though may be different ones: https://www.youtube.com/watch?v=EPBaE01ospQ

Personally I am starting to look into Westcott because of all this.

Just be aware the Westcott FJ / Rollei Freeze systems are a rebrand of (and tweaked to be made incompatible with) the Jinbei RT system. And that Jinbei's gear also exhibits the same underexposure-with-TTL Sony issue that Godox gear does. Just saying. They have at least one of the same bugs that Godox does.

Rumor is that the new XPro II-C may have a fix for the TTL+HSS bug; but I haven't seen any tested confirmation of that. No idea of the status of the Err70 bug R3/R7/R10 users are seeing with single-point AF, either.
