EOS R6 Mark II - Low light focusing

[wrk4no1]

I have a R6 mkii and last night I was photographing in very low light at a Halloween theme park. I had the hardest time with the auto focus. I had to add more time so that the focusing system would pick up, then back it back down so that I didn't blow out the shot with my flashes. My canon 5Dmkii could pick up focus in very low light with little problem. Anyone have this issue and know best approach for this?

Canon R6 mkii, 24-70mm F2.8, off camera flashes.

The image below you can see the use of my flash. This area had little ambient light, I decreased shutter speed so that i could get focus, then increased the shutter speed so that the flash didn't blow out the image.

  

The image below I had trouble getting focus without having to bump the shutter speed to allow me to get focus or use a small flashlight.

All cameras have a lower limit of light where they can achieve focus.

Camera FAQ: How Does the Low-Light AF Limit Impact My Shots?

Just a quick question, what flashes where you using, and what trigger for the flashes?

Secondly did you set exposure simulation to disable?

With Canon and dedicated triggers from some independent brands, the trigger / flash sends a signal to the camera to tell the camera the flash is ready. Your EOS R6 Mark II will see that and automatically switch off the display simulation setting and you will see the subject clearly and AF works fine. If the flash is not providing this signal then you need to manually turn off the display simulation. You will find the display simulation setting at the top of the 9th page of the red menus in your camera.
