Follow up to the selective focusing behavior.
I did some testing with both the Mark I (not yet sold) and the Mark II: Three AAA batteries with clear lettering and bright colors, two in front and one behind. The two in front were set just far enough apart so that the single focusing box (small sized on the Mark I) fit in between. All three batteries were well lit and set in the same position with the same lettering etc. facing the camera. I tested both my 50-200 and my Canon 400.
In such a scenario, there was no trouble with the Mark II because it saw no difference between the battery in the back and the front two. Both cameras locked on the same way. But when I replaced the rear battery with a small red plastic bottle with far less detail (practically none), the Mark II would refuse to stay focused on it and would always jump forward and lock onto the batteries. The Mark I did better, not 100%, but better for sure.
