cheapest flash that can be triggered optically

[ouzo]

right now I've got 2 sigma super DG 500's, the one is being used for a back light, the other on the camera. But for what I'm using it for this is total over kill, plus the one flash does not belong to me.
so i'm looking at getting some thing small and nasty that can be triggered optically. does anyone know what is available ?

Nissin Di866 works a treat

thanks

but at that price I'd rather get another sigma

Anybody tested one of these: Yongnuo YN-565EX TTL Flash Speedlite.

They go for R1790.

From what I have read And others have told me they work just fine.

If you only want optical triggering, then the Yongnuo YN560 is what you are looking for. Generally just over R1000. Can also be set to work with a TTL system so that it isn't triggered by the preflashes.

Several places in Jhb that carry them, pm me if you want the details.
