I took 6 frames of each (18), 3 manual and 3 autofocus. Run focus to infinity, focus, shoot, repeat. There was no "best one", all 6 were the same, this is a very easy target to focus on. Bogen 3001 tripod with 322RC2 head, center column fully down, 2 second self timer, fired with remote cord. Dogs were outside and I was sitting on a stool, no vibration from the floor. Target is mounted to a 3/4 piece of plywood, hung on the wall.
I was pretty surprised by the DA, resolution and color fringing. This very nearly at it's closest focus distance, perhaps not the fairest of tests. Both the FA's focus much closer than this so were well within their "comfort zone".
