Extracted from olympus website. www.olympusamerica.com/crm/oneoffpages/crm_e_sports.asp Continuous Autofocus and Continuous Autofocus + Manual Focus Use the Continuous Autofocus (C-AF) or Continuous Autofocus + Manual Focus (C-AF+MF) focus modes when shooting sports. The C-AF mode will continually track focus on a moving subject as long as the shutter button is depressed halfway. Using this focus option also automatically enables Predictive Autofocus, which anticipates the next focus point of a moving subject. C-AF+MF activates the manual focus ring on the lens so that the autofocus can focus the lens and then the photographer can manually fine-tune the focus. C-AF autofocus is not recommended for static subjects because the camera is expecting changes in the subject motion and velocity. Does it mean that the Predictive Focus is similar to Panasonic DFD? If yes, does it perform better or worse than Panasonic cameras? Can this feature work on 12-40 f2.8 and 35-100 f2.8 lenses, or must be 4/3 lenses?
