Not that I have tried many, but this was after a Ron Reznick workshop, he convinced me to try something "close up" for a change. Pacific Tree Frogs. Location: my In-Laws back yard D1H, 60mm Micro, SB-80DX bounced off a reflector held directly overhead. I was pushing into rose bushes, my wife thought I was nuts, and distance to subject was 8-10" or so. I was amazed at how long they "posed" with the flash going off and me so close. Rather fun with something this close for a change.
