Sometime last summer I had my 70-200 with me at work in an attempt to capture the local wildlife. There were a few big birds flying around our building during the day, including a hawk that was seemed to be hunting for food. While I was at it, I took a few landscape shots as well. Here's one of the Rockyview General Hospital in SW Calgary. Now, I was already impressed by this lens, but after looking at a map, I saw that the hospital was about 3.2 km away from where I was, which impressed me even further.
