A linear motor focus mechanism for the highest levels of autofocus speed and precision

VXD is a linear motor focus mechanism that enables you to easily achieve focus from the MOD (Minimum Object Distance) to infinity, even at the fast-aperture, thanks to the speed and precision of this highly accurate autofocus system. Focus tracking is also extremely precise so you can capture sudden movements by your subject. The linear motor also suppresses drive noise and vibrations during focusing, making it ideal for shooting both still photos and video in environments that demand quietness.
