I have been photographing these foxes for the last 3 weeks. What a treat to see these wild animals up close. It has been a blast watching them hunt. They do a lot of marking as they go about their business.
This image is about 85% of full-frame....tough to keep centered with a 400mm lens while they are on the move. This is where my 100-400 or 70-200 2.8 + TC 1.4 would have been handy.
