Wireless high speed sync?

[Fellipe de Paula]

How to enable high speed sync when doing off camera wireless lighting? Is it limited by the wireless gadget I'm using (I have a cheap ebay one)? Or is just a matter of settings?

Yes, it's limited by what you're using to get your flash off the camera. The ST-E2 supports high speed sync; it works best indoors when you have a direct line of sight between your camera and the flashes. I've been using one for a while now without any problems.

If you want a radio system that supports high speed sync, I believe your only option are RadioPoppers ( http://radiopopper.com/ )

I've just check my manuals and it says my radio supports up to 250th

That makes sense. All triggers will be able to support using your flash with your camera's maximum flash sync speed (most commonly 1/200 or 1/250, depending on your camera). High speed sync refers to being able to use your flash with any shutter speed.

The only remote transmitters and receivers that support high synch speed off camera are radio poppers.

hmm... So I gotta use some cords...

Your sig says you have 2 580 flashes. You can use one as a master to fire the other one remotely with HSS enabled.

Hmm must just have been everything I've looked at. I stand corrected.

One example of the exception..."Responding time: 1/500s - 1/1000s (actual sync speed varies from 1/125s to 1/600s depending on the sync speed of flash / strobe)"

Whenever I have a question like this and I have the hardware in hand, I simply try out what I want to do. Sometimes I find that conventional wisdom is not correct.

So what happens when you put your speedlites in HSS mode and use your triggers? It certainly doesn't cost you any money to try this and report back to us. Whether you are successful or not gives everyone information if you report it.

Sometimes the lag from the triggers makes the flash start late, so it ends up exposing part of the shutter. I've heard lots of people having a hard time hitting max sync with wireless triggers.

Gotcha. That makes sense.
