Personally I fly the whole approach manually, and most of my colleages do that too. Sometimes they disconnect the autopilot a bit later, but basically every landing is done manually - that is if the weather permits, since in my company it's procedure to performe autoland approaches and landings as soon as the weather is CAT2 or below.
Should it be necessary to perform a manual landing during a CAT2 approach, it's allowed to disonnect the autopilot, but not later than 80'AGL.
Hope I could help you out on this.
So long, Dave
