More impressed with the bird shots personally.

I looked at at DOF calculator and put in 135mm lens at F/ 5.6  at 200-25 feet and it is extremely large. It could miss by a country mile and still get it in focus.

200' = 176.2 feet in focus.

50'  =  9.46 feet in focus.

25'  =  2.3 feet in focus

Someone check me on that but I think that is right.
