OK for some reason manufacturers have no website info about flash gear - seriously its not there! Anyway what I am after should be simple, but I can't find the info I need and I am limited on internet time at the moment - so the setup. I have a Canon 400D, a Speedlite 580EX2 and a Sunpak flash. What I would like to do is have the speedlite mounted on the camera hotshoe whilst the sunpak is linked to it (via cable) so that both fire at the same time. I would also like to retain my ETTL with my speedlite - the sunpak flash having only its manual controls as an option - so all it needs it a triggor. However the PC slot on the 580EX2 is input only, not output, so I can't connect a flash to that - so it seems that I need a mounting point on the camera shotshoe with a PC out slot - which is then connected to a cable and thus to another hotshoe point with a PC in slot - to which the cable is connected. It's cable based because cable is reliable, cheap and smaller than wireless options and the whole setup is going to be mounted on the camera in some form so it does not need to cover any great distance. So has anyone any products to recomend for this (UK availible is ideal - if its on Amazon UK it's fantastic!). This should be really simple to find, but so far the only info I am getting to is all wireless based. I have found the following; hama.co.uk | 00006951 Hama Hot Shoe Adapter Centre. hama.co.uk | 00006952 Hama Hot Shoe Adapter Cable Which would appear to be what I am after, but I am not sure of the cable connection points - and sadly (as you can see on the website) there is no info at all about that!
