Using PocketWizard Flex TT1/TT5 via TTL passthru mode
I already own a PocketWizard Flex TT1 and two TT5's and a pair of Canon 430EXII's, so I'm sorted for TTL nonsense. However, I'm very interested in your V6/RF60 gear and was wondering if the following scenario would be possible:
I started thinking that, if the V6 TTL passthru mode makes a flash (e.g. 430EXII) think it's connected directly to the camera, would it do the same for a Flex TT1/TT5? My idea is simple. I would like a pair of RF60's as background lights, with a V6 on-camera controlling their power/zoom settings. I would then have a Flex TT1 on top of the V6 (with passthru active) which would trigger a Flex TT5 with 430EXII attached in TTL mode. That way any subject movement/changes in front of camera would be handled by the TTL of the PocketWizard setup and the non-changing background would be light and controlled by the Cactus system.
Before anyone chimes in and suggests just getting another TT5 and 430EXII, along with an AC3 from PocketWizard, it's actually CHEAPER for me to get the Cactus gear! Plus the RF60 is more powerful than the 430EXII. Anything more powerful from Canon really starts pushing the budget.
One snag springs to mind - with a device (flash, TT1, etc.) attached to a camera-mounted V6, in TTL passthru, can the power of remote RF60's still be adjusted via the V6?
I look forward to hearing your thoughts,
