EOS R100 settings for external PHOTOOLEX LCD flash

[shopstefanov89]

Hi,
I need a help about my canon R100 and Speedlite Flash settings.
I bought PHOTOOLEX LCD



When I use manual settings on the camera and turn flash on the external flash is working but the camera is not in "external flash mode"
When I go to
flash control -> external flash func. setting
it shows :
" This menu cannot be displayed. Incompatible flash or flash's power is turned off"
When I try it with my neewer strobe it shows the same.
I am a new and need a help with it please.

Thank you.
Now is on TV mode and I set "Second-curtain synchronization"
And I don't know where should I see 2 visible flashes?
But in that mode is still dark the photo.

For this test don’t worry about the exposure. When you fully press you should see the metering pre-flash. Then the main flash at the end. Or you could dial in a long shutter speed such as 30 seconds. The 2 flashes should be more visible.

I am not sure what is metering pre-flash and when I press it don't see anything different and I don't know is the 2 flashes should be more visible.

please have a look what I see on my camera:

With E-TTL and other TTL flash systems for digital cameras. They will fire a pre-flash to determine flash power. Old off the film TTL relied on light reflected off the film. So there was no pre-flash at all. If you’re only seeing one flash and the shutter speed is set to 1/30th of sec or slower. Then the flash is set to Rear/ 2nd Curtain Sync. There may be a problem with the flash. I’ll double check the manual to ensure the 2nd/ Rear Curtain Sync is available when the shutter speed is set to 1/30th sec or slower.

What custom functions do you have set on the speedlite. I can see it has Custom Functions set. What Custom Functions are set on it. You can see it from the Speedlite Custom Functions menu. Take a picture of what Custom Functions have been changed.

Does the built in flash work correctly or is it still underexposed. Can you test the speedlite on a different Canon camera. Or can you use a different know working Canon Speedlite on your camera to see if it works.

Please have a look the attached photo of it.
I have never change it, it's been always like that:

I can't test anythinhg else..

I think the built in flash is ok but I think today on the photoshoot was not very ok as well (not sure will test it tomorrow again)

Check all of the flash Custom Functions not set to 0. On all of Canon's speedlites 0 is the default option. So what are the others set to with the 1s in blue. Those could be affecting your speedlite causing issues. So take a picture of what those are set to.
