I may have to a chance to visit Costa Rica sometime in mid-late summer. If I go, my focus will be on finding and photographing wildlife (sloths, monkeys, frogs, snakes...you name it, but especially birds). Right now I have a 500/4 IS (v1), 70-200/2.8 II, and a 100 and 180mm macro, among other less-wildlife oriented lenses. Bodies are 1D3 and 5D2. I also have teleconverters. I've long desired more reach for here in Ohio, but I wonder what the ideal lens is for bird photography in CR? Take for example the 800L. This may be an ideal lens here, but in CR is it too long/dim? Of course if I ever did upgrade to an 800, I would also get something like a 300/4 as well.
I don't know...just random thoughts I guess. It would be a once in a lifetime trip and I'd want to make the most out of it.
