I finally got a chance to test my new toys, the 7DII and 100-400 II. I took it to a small pond on Long Island where there were some gulls, mallards, Canada Geese and a swan. Here's one of a mallard. Unfortunately, one has to stay on a slightly elevated boardwalk at this pond so no getting lower but still good for a quick test. I got enough sharp results that any that weren't I will attribute to operator error or movement.
