EOS R: Exposure simulation with flash

Danielsnake — Thu, 06 Jun 2024 21:38:54 GMT

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.

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.

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

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

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.

It doesnt happen to Sony. You can also try if Sony flash/remote will work on Canon camera. It might just trigger flash in manual mode and keep flash from deactivating exposure simulation. I was thinking that this is only Canon RP limitation. But seems this bug left unattended for many years.

The only solution would be through modified firmware. That will deactivate flash and only activate it then release button pressed. Never had such issues with Sony camera. Once switched back to Canon I was confused, and thought it is only limitation of Canon RP, that cant shoot really with electronic shutter etc

I am not sure how Canon suggests to work wedding photographers to continuously deactivating flash. It feels the same as if camera hangs autofocus after each shot, but no worries there is a workaround to pull the battery after each shot or install switch on external power pack 😉

I will try to use Profoto trigger for Sony camera today. But it may not have a central pin. I am also getting Nikon trigger for my friend this week. I will try and use it if i can still use the flash and control power on a remote.

So weird solution can be to to carry Nikon transmitter or seal pins on the shoe. Maybe even better permanently on Canon body ))) lol

Manual mode is great. But i can imagine wedding photographers may not appreciate then camera going into DSLR mode and they need to recheck and correct each shot. With the risk to blow up exposure, just because they was thinking exposure is correct by looking at viewfinder.

Your camera shouldn’t be locking up after shots. I’ve seen off brand speedlites cause the camera to lock up.

The "workaround" I found is to use a button on the camera to switch the flash on/off. On my EOS R6 Mark II I can configure a button to do this with custom controls, and for the EOS R10 the camera has a button assigned on the right of the cross keys to do this. I cannot find a way to do the same for the original EOS R6 though.

I have now an r8, the story is the same, i wish canon would give us a second exposure simulation option, one that does not deactivate with the use of on camera / trigger flash, si we can easily and quickly nail our ambient exposure and add the slightest touch of flash.

The best way to pass that request to Canon is use the feedback link on the main Canon U.S.A. website
