Interesting for me Graeme as I have been looking at a simple flash trigger for a while. I realised for outside radio operation was the way to go. Like to know more about these and price. I have been looking at this set up. No TTL but that is all I need really. http://www.srsmicrosystems.co.uk/9456/Phottix-Ares-Wireless-Flash-Trigger-Set.html . Are these Yongnuo ones TTL or simply manual , radio and a good price?
Thanks Graeme I'll have to look into this. I wonder if they do a sigma version? I use my canon 430EX 11 by using tape on some of the pins and off camera with a lead. But would like to get away from a lead altogether. Mmmmm more expense though.
