Re: Some advice on speedlights need please - Nissin/Canon/Yongnuo

Thanks for your replies - I appreciate them, and I hate it when dp crashes!

I should have made clear that if I invest in the Canon system, it will be one flash for the time being and I will be adding a second unit + ST-E3 later on some time. So I intend to make it Canon sxclusively, but I wondered if for the time being I could have a dual flash setup with my Nissin while I wait to save up for the rest of the Canon setup.

So I agree, the Nissin + one 600EX isn't ideal, but it is either buy another Nissin flash + Cactus trigger now and maybe add another Nissin later on, or start to invest in the Canon setup, but it will be slower so I will learn the capabilities of Nissin + 600EX for now, and look forward to an exclusive 600EX setup down the track.

Am upgrading to 5D3 + lenses, so I can't afford to buy more than one 600EX right now.

Actually, it can be possible to make an optical Canon Wireless link work even when the Canon master is itself being driven (in M) by a simple (manual only) RF link. But, even if you got that to work, I would not recommend doing so. First you lose ETTL & HSS etc, but then even in M mode both units incurr a timing penalty, so your max sync speed would drop 2 clicks at least. Far better just to buy a second Cactus Rx ie one for each off cam speedlite.

" ... how would I go working out which power settings to have the Canon 600 and Nissin 622 at exact same power? Is this easily done? Or a trial and error thing? ... "

Basically you could estimate from their Guide Numbers (specifying; iso, m or ft, speedlite zoom setting - and - if necessary, allowing for light modifiers). Then tune with an external incident flashmeter.

Overall, I would advise rethinking your whole setup from scratch, focussing on need/task. Canon's RT system is designed to be self-contained and excludes other kit/tech. What it does, it does very well. Cheers, Donald
