I have a Canon 70D with a Canon Speedlite 580EX II.

This may be a duplicate question, but I can't find the answer.

I can't get the flash to go off in live view mode, either the external flash or the pop up flash. Is this a setting within the camera that I need to adjust in order for the flash to fire?


The reason why the flash isn't triggering is because you have silent shutter activated on your camera.

To disable it on your 70D please go to the Camera 2 Tab of your menu and then change the Silent LV Shoot setting to disable. http://web.canon.jp/imaging/eos70dshootingguide/function/index.html

Have a look at these different articles: http://martybugs.net/blog/blog.cgi/gear/lights/Triggering-Flashes-While-Using-LiveView.html http://www.p4pictures.com/2011/02/live-view-mode-and-flash-on-your-eos-dslr/


Normally Canon speedlite disable the Silent shutter. However your flash model is 6years older than the camera so it might not have that feature.
