Canon wireless flash system (600ex-rt + st-e3-rt)
May 16, 2012

I just bought two 600ex-rt and one st-e3-rt to use with my 7D.

It turns out that unless I upgrade to a camera released in 2012 or later, I can not use high speed sync and I can not sync to shutter speeds faster than 1/125. When used with a 1D X or a 5D mk III these restrictions do not apply but for all other Canon cameras the do.

I'm quite disappointed by these restrictions. I'm wondering if Canon will be making a firmware update that will make the new wireless flash system fully functional on my 7D (and for all other current xD bodies for that matter).
