Speedlite 600EX-RT Won't Work

[miketerndrup]

I have a off camera flash that I can't get to work any suggestions

I'll ask one last time for details.  Now that we know you're using it on-camera, please provide full details of your camera settings related to flash along with what mode you have the flash in (Manual, ETTL, etc.)

[rs-eos]

If you have the flash physically connected to the camera's hot shoe, it is ON camera.  Only when you have the flash not connected to the hot shoe is it considered OFF camera.  And off-camera can be controlled in one of many ways to include a sync cable, built-in flash to be an optical trigger, master flash in the hot shoe to be a trigger (optical or radio), or a dedicated radio trigger in the hot shoe such as an ST-E3-RT.

OK, understand.

That is generally called "External Flash" since it is external to the camera. Could be in hot shoe, connected via cable or connected wirelessly.

Didn't see a response to question relative to test button. If you press the test button on flash does it fire?

Do you have access to another camera?

Just trying to separate a flash unit problem from a camera problem.

it only light up half the room when I test it

I just have the flash

I don't understand what that means, but since it fires when you press Test it sounds like a camera or camera compatibility issue.

Since that is an older flash unit perhaps you should register your product (if you haven't already done so) on the Canon support site and then request Canon support.

I have it register

Give Canon a call then at 1-800-OK- CANON
