ISO 1200: Hands on with the New Canon 600EX-RT Speedlite & ST-E3-RT Transmitter


The Future of Strobist- Hands on with the New Canon 600EX-RT Speedlite & ST-E3-RT Transmitter ( and new 5D Mark III ) | ISO 1200 Magazine | Photography Video blog for photographers.

A little on a tangent away from video here, but still in the camera realm.  In this post, Syl Arena says that if you are a Canon user and a fan of photography with off-camera Speedlights, your world is about to get rocked.  Overshadowed in the release of the Canon 5D Marklll was that Canon also released a new radio controlled flash.

This is huge for stills guys.  Why?  Because now you have easily mountable, light weight, battery powered light that you can control from anywhere.  Want to make the flash a softbox source?  You can since you don’t need a line of sight to control it.  Want to stick it outside a window and shoot inside?  No problem.  Most of this has been possible before now with 3rd party gear.  The one nice thing that sets the Canon solution apart is that the communication is 2 way.  The flash that’s 50 feet away behind a wall will tell the photographer that it is recharged and ready for the next shot.  Cool!

On a side note, I’m so envious of stills guys when it comes to light output.  To have enough HMI’s to replicate what Syl can do with a few battery powered flashes would weigh a ton, require extra crew, generate scads of heat and probably overload any house hold circuits.  I guess I’ll just have to keep waiting for the fuel-cell powered high output LED lights with integral anti-gravity bases 🙂
