About a year ago I asked some questions about types of cameras to get. Since then I've purchased a GoPro Hero2, a Fuji XP50 waterproof/shockproof...etc, and last week I got a Nikon D5100 dslr with 2 lenses....18-55 & 55-200. My question now is what would be a good 3rd lens to pic up...within reason. I'm no professional but I do like wildlife pics so I'm thinking a stronger telephoto lens. Maybe something in the $500 range as I dont want to break the bank just yet.
