The old style 80-400mm Nikon zoom I was using is available on the used market pretty cheaply for what it is, because it won't autofocus on D3xxx or D5xxx cameras that don't have internal focus motors. But that 400mm focal length will get you right in there with the critters.
I thought about using a crop sensor body, since the narrower field of view would give an effective 1.5x focal length boost. Maybe next time. These were all shot with the D3.
Man, a bad day taking pictures at the zoo is still a pretty good day. I really should spring for a membership.
