While photographing migrating ducks not far from an eagle's nest, one of the eagles flew right above and past me. It's great having a fixed aperature lens, but this is an example of when a lens that zooms back out would have come in handy. But I'm not complaining. It's a beautiful sight, being able to observe it so close up.
