High speed sync problem on EOS R8 with NiceFoto TTL-680C

Why doesn't the shutter speed in Canon R8 camera go higher than 200? Even though I set it to high speed in the camera settings and also synced it with the trigger and flash, I tried with the 6d ii camera and it worked, but it doesn't go up on the r8, my flash nicefoto 680c, trigger tx_c01

I think you have restricted the shutter speed with flash in your camera.

Please check the red menus in your camera and on the 3rd tab you will find External Speedlite settings. Select this and look at the Slow synchro settings. It is possible you have set the to 1/200 sec. (fixed), and if so this is the reason. This setting means that when flash is used the shutter speed will only be 1/200 and even with high speed sync enabled the limit is still active. You need to choose one of the other two options and then you can use high speed sync.

I did this too, but again my shutter speed doesn't go higher than 200, and this is really driving me crazy. I also updated the camera to the latest update

Is the camera in manual exposure mode M? If so can you switch off the flash trigger and set a shutter speed more faster than 1/200th, so maybe 1/500th? If you can, then switch the flash trigger back on. Make sure that the trigger indicates it is in high speed sync mode, and also the camera menu shows high speed sync. The shutter speed should remain at 1/500th when you half press the shutter.

If it still is a problem. Check the custom functions, it is possible to limit the shutter speed on the second page. But if you could set 1/500th then it's not that. Most likely that at that point that it's a trigger compatibility issue.

No, unfortunately, it is not possible. In normal mode, when the trigger is off, the shutter speed varies up to 4000. In manual mode, it can be changed but when the trigger is turned on, high speed is shown on the camera, trigger and flash, but it is not possible to increase the shutter speed above 200, in your opinion, Is it a trigger problem? What trigger do you suggest for this camera and flash?

What type of flash shoe is on the R8?  You might need the need the Canon ED-E1 multifunction shoe adapter to use the older strobe.

I don't know much about this, can you introduce a trigger that can solve this problem?

Hi,

I thought this might have to do with electronic shutter?  However,  I don't know enough about older flashes.  I'll ping Demetrius so we can get another set of eyes on this.

Thank you bro ❤️ 

Does HSS work with any shutter mode. This is a common incompatibility with 3rd Party speedlites. 3rd Party Speedlites don't work correctly on the EOS R series and HSS. Can you test out a Canon Speedlite to ensure HSS works correctly.
