Getting the Hang of My Tokina 400mm with Pictures of the Moon.

Getting used to a long lens isn't like getting to know the average lens. Focusing is tougher, even with autofocus if it works. I've been getting to know my used Tokina 400mm F/5.6 ATX SD lens over the last few weeks. I think I'm getting the hang of it. My bald eagle shots came out great yesterday and tonight I got some really nice pictures of the Moon.
