http://SmokingStrobes.com/odin - I really can’t praise this little piece of gear enough. Finally a reliable radio trigger for Canon ETTL speedlites. I don’t leave the house without it anymore. So if you are shooting Canon, then this is a must have. If you are shooting Nikon, then you should hammer the Phottix customer support to release an Odin for Nikon. Really.
