Hiya Quinn. I have to agree, the composition and DOF of #4 are wonderful. Plus I have to give you extra points for handholding at 600mm (anything over 300mm-400mm and I usually bring my monopod along). Misha - I hear that if you jump in with them and do the "hokey pokey" (hey, that's what it's all about) then you can get some really nice action shots. Never tried it though. Still, the napping is very interesting. Wow, if you could get a shot like that with the cat looking at you, I bet that would be killer.
