I have had my canon 85mm f1.2l ii usm lens for about a year now. Love the pictures I get from it. I have not used it for almost months and the when I recently used it I noticed that whenever the focus is locked from depressing the shutter button half way, the AF still moves back and forth ever s slightly.
I am used to once the button is press far enough to get the focus lock, the AF stays perfectly still until the picture is taken. Was this something I just didn't noticed in the pass? Does anyone else who have this lens encounter this issue? My other lenses do not do this.
