Here's another tiger photo I took, since I was not able to get any overly interesting wolf photos lately (they are just being lazy and on top of this, it's getting dark really early now, before they are active again).
Anyhoo... I got the photo while this tiger was walking through the dense undergrowth, pretty close and thus the frame (taken with a 400mm f/2.8) is very restricted. He was probably only 3-4 meters away so this photo is actually pretty much full frame.
Following him around at this magnification and keeping him in focus wasn't easy through the thick glass that separated me from him, but I think this one worked out pretty well.
