New Lens!!

Today I just got a new Nikon Telephoto lens (80mm-200mm)!! I'm really excited to start using it and get some new type of pictures! I wanted to go out and use it today, but unfortunately its raining/snowing and I dont want to get my camera (or myself!) wet.
I'll post some photographs I take with it when I get some!

Any tips about using a larger/telephoto lens?
