EOS R: Exposure simulation with flash

Danielsnake

Hello dear canon community

Does anybody know if there os anyway to keep active exposure simulation on the R series while using flash?.

I know, no flash can be simulated, I'm aware of that, what I'm after is to make the camera simulate exclusively for the Ambien light, while i use flash (ocf).

I have looked for several days online, and apparently i can't be done, if this is true.... Why would canon do something so... Stupid really, to their cameras?, turn their mirrorless basically into dslrs again if you want to add a touch of flash to an image.

Hello and welcome to the forum.

A similar question was asked in another post, and there is no way to stop the exposure simulation from being deactivated when a Canon dedicated flash is on the camera and charged. 

Depending on your camera there might be a workaround solution available where you can have customised button set to deactivate the flash firing so you can see the effect of exposure simulation then reactivate flash firing to take the actual shot. This is possible on my EOS R6 Mark II, and also using the right cross key on the back of the EOS R10, but not possible on the EOS R6.

Is this issue exclusive of canon flashes, or does it happens with all brands?

Any brand that is intelligent enough to communicate with the camera for TTL flash control will operate this way. 

If I use an old simple radio trigger with only a single central connector on the hotshoe and use it to trigger some studio strobes then the camera does try to simulate the exposure, but that is typically pointless as 1/125th f/8 iso 100 in a studio is often a black frame u til the strobe is triggered. So for that I disable exposure simulation to be able to see what’s in the frame by the light from the modelling bulbs.

I'm gonna try cover all but the central connector and see what the system does...

It will probably fire the flash, but you will lose all automation including flash metering, and the ability to do high speed sync. If you leave the Speedlite in ETTL then you'll get a 1/32 power only.

My advice is to always use the camera in Manual mode when using any flash. With the flash, (or trigger), in the hotshoe, and exposure simulation enabled, just turn off the flash (or trigger) momentarily to get an idea of the ambient lighting exposure. 

This should work for both DSLRs and Mirrorless cameras.

It is what I've been doing, but it is so inconvenient.

 

I feel like going backwards with new tech, back to the dslr era...

 

Yeah, that's it, it feels lika a stepback
