So I've been using the AF patterns and noticed something that explains alot after the new zoom on AF point feature was implemented. I usually shoot in this pattern:
At first everything seemed OK but I did notice that the lens would hunt a lot sometimes missing focus completely or bouncing back and forth through the range, etc. Well with the new feature it turns out most of my photos are focusing on
#2. It seems as if the middle point is ignored as are the other ones usually. If middle and other points are over the target the lens will hunt or bounce until #2 is positioned. It all looks as if only #2 was selected with manual/individual even though the other dots light up.
Also wish you could turn off focus on AF point during review..... maybe I missed it in the setting somewhere.
