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.
A stepping motor unit for high-speed and high-precision autofocus
RXD is a stepping motor unit that helps you stay focused on the action. RXD uses an actuator to precisely control the rotational angle of the motor, allowing it to directly drive the focusing lens without passing through a reduction gear. A sensor that precisely detects the position of the lens enables high-speed and accurate AF, which is ideal when shooting continually moving subjects or recording video. And a focusing system that is both smooth and quiet lets you shoot free from stress not worrying the drive sound in a quiet environment.
DC motor with a great silent operation
A newly developed OSD (Optimized Silent Drive) that ensures silent operation. Operating noise has been appreciably reduced thanks to a revamped and optimized AF unit.
The precision and speed of autofocusing are increased to ensure accurate focus even when tracking constantly moving subjects.
