600EX RT + transmitter + 5d MK2 Sync speed

[henrik12]

Have anybody tried or heard about the 600ex-rt hss issue on a 1d mk-lV?

I can't find anything!

Up to now Canon has not even announced receivers for their own speedlites (580/II, 430/II). I really hope they will - and at a reasonable price.

The problem seems to be that Canon currently has problems with the "reasonable price" part. And if the receivers are nearly as expensive as the st-e3-rt controller, people might just upgrade their complete flash because you don't have to screw a receiver under each older one.

What I'm hoping for is a receiver for dumb ttl and studio flashes that would make 3rd party systems obsolete - pretty please, Canon? We might even forgive you the fact that radio remote still doesn't work with 2nd curtain...

In reality I am afraid, Canon will move very slowly and half-heartedly on this ... until Nikon brings out a way better system.

I'm sad to say that I don't think Canon will update the firmware of older bodies like the 5d2 to work with group flash, because that's the one really important thing that is better on the 5d3. Canon even went out of their way to conceal the fact that hss and radio flash seem to work without drawbacks on the 5d2 :-o

Just wanted to add in on the subject. I just got the 600ex rt and the st-e3-rt and used them for the first time on a wedding shoot.

I can confirm that you can enable high speed sync on the st-e3 and it will allow high speed shooting on the 5D mkii... I did syncs in the 1000s and the flash still served well as a fill in daylight sunny.
The mains issue though being that the flash gets hot fast and the batteries last somewhere around 500 shots.

Nevertheless... it possible. I did notice on some of the smaller speeds around the 200/500s that there is some power loss, but I can work out how this all fits together.

EDIT: by the way... I also got the Lastolite Ezybox (38cm X 38cm) and had the assistant fire it up in the air in the churc. At full power, even through the Ezybox, the flash provided a very nice ambient fill!
