Ring USM drive, high-speed CPU and optimised AF algorithms to provide quiet and fast autofocus.
SWC coatings combine with improved lens design to minimise ghosting and flare.
A Fluorine coating on lens surfaces reduces dirt clinging to the lens elements and prevents smearing.
Full-time manual focusing enables instant manual focus control.
Power focus mode added to the focus mode switch increases versatility during movie shooting.
Dust- and waterproofing enable shooting in harsh conditions.
9-blade circular aperture creates beautiful out-of-focus highlights (bokeh).
