Impressive pet, I mean, shots, Peter.
My current main camera is the RX10 I, but I am seriously considering upgrading to either the II or the III.
I certainly don't have a desperate need for 600mm instead of 200mm (FF equivalent) max, but it would sometimes be handy (such as when chasing snakes in trees). The viewfinder on both the II and III seems much better than on my I, but I wonder whether the extra 9 ounces weight of the III would make it less comfy to have around my neck for long walks.
Care to comment on your reactions to the III?
Cheers, Eric
