" .. or am I going to be forced to buy a total of 4 Pocketwizards? .. " Yep. Or consider Phottix's Odin TCU & 3 Odin Rxs Or, even Yn's 622N - though that's not quite as smooth.

Hi, Ezybox Hotshoe S'boxes are good modifiers - I have a 24in & a 32in. But on a vertical stand they are 'front heavy'. If you then put that onto an angled boom it can translate into a twisting...

Hi, The 'Interfit Strobies Boom Arm with Hotshoe for Light Stand (STR173)' is designed to fit onto the top 5/8 spigot of any lightstand. But that really is lightweight - it probably will take a...

Hi, You mention TTL or M flash but a third option is Manual flash, but M flash remotely adjusted from the camera position. (And I think those M increments would be frustrating.) Often it's easy...

Hi, Not sure if Bluetooth can be fast enough .. If all else fails, it's always possible to use off-cam flash like this: The 580ExII is been driven by a simple optical slave device, which in turn...

Phottix Mitros for Canon. It's new and I havn't used one, but that's what I would buy today. (I use 580ExIIs & 550Exs that I've had for a while.) I have used Phottix kit and I know they are trying...

Hi, There are items like this Interfit light boom arm with Wt & adaptor: http://www.karlu.com/interfit-section-boom-arm-p-8370.html Do not use them with the lightest category of light stand - the...

Hi, Kacey do a plastic BD at a price . . . Lumodi too.

Hi, I don't use Yn 622Cs, but I'd be extremely surprised if that worked, even for Canon Manual Wireless, let alone, ETTL. I accept the point, made above, that you could get away with only 2 622Cs ...

Hi, Although Canon's RT kit is clever, it has the limitations listed above from a 5DII. Also Canon made it pretty exclusive in that it works with no other brand including Studio Strobes (at least...

Hi, You would need 3 Yn 622Cs - one for cam body & 1 each for each Speedlite. Bear in mind that 'II' series Canon Ex Speedlites acquire full remotely adjusted control & triggering (both ETTL &...

Hi, You say " .. the flash will fire a pre-flash to determine the amount of power needed for proper exposure on it's own .. " Which is correct - though there are exceptions. But when this applies,...

Hi, I would concur with pretty much everything Zee said about Evaluative for Flash and Average for Flash. There are two cicumstances where these are both over-ridden. The first is with using FEL:...

You are correct on both points. Canon's RT radio tech - so far - is not compatible with any other radio based system. And I suspect Canon like it that way. If you are going the Yn622C route, then...

Hi, S2 mode, driving a remote slave, (Nissin calls it SD mode) will work with/from a single camera mounted (or ETTL cord mounted) ETTL Speedlite - some of the time. I would not rely on it. Using...

Hi, What Sailor Blue says is correct! But he's presuming that you have no interest in using many of the features of your expensive 600Ex-RT. Like its ability, in combination with the camera...

Hi, As above, don't buy that umbrella adaptor! Do a proper search within the Strobist Flickr site. DH reminds you - but you may have missed - that the hole for the umbrella shaft should not be at...

My answer now - look very closely at the Phottix Mitros. Perhaps wait for a couple of reviews if you can. My answer 3 yrs ago was to buy several old Canon550Exs - I have not regretted that...

Hi, I did buy a couple of Ezyfold Ebay Speedlite Softboxes, a 24 X 24" & a 30 X 30". They are easy to use - I would go for a recessed front panel design. Remember you can mask off the diffusion...

Hi, The light from a 12" BD at say 4 ft is pretty hard - your link points to an even smaller BD, so at common working distances, you are going to get rapid light to dark transitions. As mentioned...
