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.

Help!

are you sure you didn't accidentally select your AF mode to AI Servo instead of One Shot??
