Congrats,
Agree w/ the comments about the tripod collar. If you want to have some fun (OK so I am unusual) put an extension tube on it had walk around in the flowers at the local botanical garden - bugs, bees, flowers lots of fun. Yea, its heavy, and you focus more w/ the zoom than the focus ring, but what a blast - the IQ the lens is capable of is plenty good for an extension tube

It is my favorite lens by a long ways.
