I have been trying to figure out if I am having focusing issues. I tried to MF adjust and got a +12 for my 70-200 f/2.8 II. Here are 2 sample shots. The first picture I intentionally focused on the tip of the nose, and for the 3rd shot, I focused on the cat's right eye. The 2nd and 4th shots are just close to 100% crops of shots 1 and 3. These shots are handheld, but when I was trying to MFA, it would seem like 1 out of every 5 or 6 shots would be off slightly, even though I was using a tripod. Or is it sharpness issues I am dealing with and not focus? Each shot was at f/2.8 1/250 ISO 100 with off camera flash bouncing off wall to camera right
