Radio Flash for EOS Systems
The Canon Speedlite 600EX II-RT is a shoe-mount flash with built-in 2.4 GHz radio transmission for wireless control without line-of-sight. It delivers a guide number of 197 ft at ISO 100 and 200 mm zoom, and covers 20-200 mm or 14 mm with the wide panel. The head tilts -7 to +90 degrees and rotates 180 degrees left and right. It runs on four AA batteries and weighs 0.96 lb.
Suited for Multi-Flash Radio Setups
Photographers who need reliable off-camera triggering through obstacles will benefit from the radio system. The fast 0.1-3.3 sec quick-flash recycle supports continuous shooting up to 2.0x faster with an optional battery pack. Buyers who want a smaller on-camera unit or who only shoot with optical slaves should look at something else.
2.4 GHz Radio Transmission Decides Fit
The integrated 2.4 GHz radio is the single specification that determines whether this flash fits the workflow. It enables commander or slave operation over long distances without infrared constraints. If the shooting environment relies on optical triggering or the camera lacks radio support, this model adds capability that will not be used.

Questions about this item
What radio standard does the 600EX II-RT use and what does it replace?
The flash uses 2.4 GHz two-way radio transmission and replaces line-of-sight optical systems, so obstacles no longer block wireless triggering.
What are the dimensions and weight that determine if it fits on my camera?
It measures approximately 5.64" x 4.83" x 3.10" and weighs 0.96 lb, so it fits any standard hot-shoe with enough clearance above the viewfinder.
How do I install the batteries and what mistake should I avoid?
Load four AA alkaline or Ni-MH cells into the battery compartment; the common error is mixing old and new cells, which shortens recycle time to the 5.5-second worst case.
