I'm new to off-camera flash photography, and this question confirmed my guess that you don't have to have off-camera flashes of the same brand; but I need a bit more info.

I've got a Canon 40D, Speedlite 430 EX II, and Sunpak auto 355AF (an old Pentax flash).

The only setup I can think of to get both flashes to fire off-camera are 2 wireless receivers (hooked up to flashes) and 1 wireless trigger (on 40D).

I'd like to hear if there are any alternatives to set these 2 flashes up off-camera; and some wireless trigger/receiver recommendations.

Are you sure that the 430EX II can be triggered by the 40D's pop-up flash? I thought it needed a line-of-sight infra-red signal from a 580EX or similar. – Oddthinking Mar 2 '11 at 14:30
@Oddthinking: my bad, 40D can't trigger a flash with its built in flash – roman m Mar 4 '11 at 2:38

Cheap Radio Triggers

I am using triggers similar to these.

They are cheap, and work very well (a few misfires / nofires, but still great for the money)

Alternatively, you can just use a sync cable for the sunpak and leave the 430 on slave. (Check that the sunpack is low voltage first - i.e. it's safe to attach it directly to your camera).

Could you name the device, because the link just returns a 404 error. – Miljenko Barbir Jun 13 '12 at 5:28
@MiljenkoBarbir, I've added another link. – AJ Finch Jun 13 '12 at 13:54
