November Challenge - Close Up - New Toy

Day 15 of the November Daily Challenge - Close Up

Yesterday I mentioned that I had just taken delivery of a new toy. Well, here it is, close up.

The more astute of you will probably guess that it is a lens.

The JohnGravett among you can probably guess which one - there's a drink in it for you John if you get it right first time.

Unusual to have the Depth of Field markings on a modern lens, so that's a clue.
