Off-camera flash with 80D

Roo — Wed, 09 Aug 2017 13:19:10 GMT

I am new to flash photography. My camera is an 80D and I have a 430EX II. I would like to find a way to fire the flash off-camera without having to fire the camera’s pop-up flash. Any ideas?

There is no other way without getting a ST-E2-RT transmitter which mounts on the hot shoe. You can't see the light emitting from it but it's essentially the same as your built-in flash.

Isn't it only the 430-EX III that has RT capability? I was under the impression that optical transmission is the only option with the 430-EX II.

Ah, too bad ... Thank you for your response, though.

One more question: Do you know if the ST-E2-RT transmitter emits a light as bright as the flash?

Yes that's right. That's why I mentioned the ST-E2-RT not the ST-E3-RT. The E2 transmits optical info only which the 430 EX II can do.

As I recalled, you can't see it, at least it's not noticeable as the photographer looking through the viewfinder.

Hmmm,,, I don't find an ST-E2-RT, only an ST-E2. Which actually doesn't surprise me much, because I always thought that RT stands for "radio transmission". Is there a radio-capable version of the ST-E2?

Oh...I see what you're getting at. I just worked off memory...Sorry...you're correct it's just ST-E2...I guess I don't sweat the minor details that much.

Pop-up your on-camer flash.

Go into the camera menu and tell it to "disable" your flash.

Use it normally.

What you'll find is that you SEE the on-camera flash fire... but when you inspect your images you wont see any light from it.

The camera will use the on-camera flash ONLY to communicate with the external speedlite (which all happens while the camera shutter is still close... a fraction of a second before the shutter opens) but when the camera shutter opens only the off-camera flash will fire.

You get the benefit of off-camera flash without having to worry about what the on-camera flash will do to your shot.

I know it seems strange to turn on a flash, tell the camera menu to "disable" it, and still see it fire... just know that it is only firing to communicate (optically) with the off-camera flash units and it only happens when the shutter is still closed.

Go to your menu,,,, camera 1..... “flash control”.....”built in flash setting”.....”wireless func.”..... select the flash only... verify that the chanel is the same as on your flash
