EOS R6 Not Showing Exp.Sim After Upgrade to Firmware 1.0.7


3 weeks ago I bought the canon eos r6 body, I use it together with the original canon lpe6nh battery, canon rf 28-70 f2 lens and sometimes together with canon bg-r10 battery grip; The first thing I did was update the software to the latest version available 1.0.7 to have access to clog3, I didn't have any problems in this process, the problem occurs when I'm taking photos, I can't see the changes live in the viewfinder or on the screen of exposure that I do, I have to take the photo and go to the gallery to see them, in the camera I always have the option of exposure simulation activated. occasionally this problem does not occur, but after 1 or 2 shots it reappears without changing any parameter in the menu, when I enter the gallery or the menu, and then I shoot again, it allows me to visualize live the exposure changes that I am making , but after that 1 or 2 shots, it goes crazy again and I have to repeat the process again, the strange thing is that when recording video, which is what I do 90% of the time, everything works perfectly, all the parameters that change allows me to view them live without any problem, but when I change to manual photo or any of its photo options, the problem reappears, I don't know if it's a problem with software, or a camera problem, don't use it before updating to 1.0.7 so I can't tell if it was working correctly or not before, what can I do?



I forgot to say, I already tried it with different batteries, different sd memories, resetting the factory settings of the camera in case I had moved something, but it continues with the same problem

Are you using a Canon speedlite this will DISABLE Exposure Simulation AUTOMATICALLY. The camera CAN NOT predict how the picture will come out. Since it doesn't know how the flash is positioned direct or bounce flash. Therefor Exposure Simulation is AUTOMATICALLY DISABLED and CAN NOT be used with flash photography.

Thank you very much for answering! I don't use flash, however I have realized that if I shoot using the touch shutter on the screen, the camera works perfectly, but if I do it through the shutter button, the problem I mentioned occurs

Do you think I should take it under warranty? Or could it be a software problem?

There is probably nothing physically wrong with the camera.   It is far more likely that there could be a camera setting somewhere that is responsible for the differences you are experiencing.

The only real difference between using the EVF compared to the rear screen is which screen is showing you the display.  Unlike a DSLR, both displays use the same focus hardware and camera settings.

I recommend resetting the camera back to factory defaults.

"The right mouse button is your friend."

I just restored the factory parameters and it continues with the same problem, I have restored both the custom controls and the network and the camera in general. the automatic luminosity parameters are turned off, and the exposure simulation active, what I have investigated these would be the only parameters that could cause me the problem due to a bad configuration

Do you think it could be something from the software update?
