Beware of compatibility! Hard to get information on the 'standard' for these triggers and such, I have struggled to fit on my Lumix G2. The pictures do not even show the number of jack contacts and no compatibility list is given. This is also one of the points that Amazon should be more demanding on its website: the technical descriptions are often too light. Also a flash shoe on top of the housing that holds this precisely claw would have been appreciated ....
