Sony unveils RX10 IV camera with world's fastest auto focus

Expanding its Cyber-shot RX10 series, Sony on Tuesday launched a new RX10 IV camera in India, starting at Rs 1,29,990.

Available from October 14 at Alpha flagship stores and major electronic outlets, the camera claims to have the world's fastest, 0.03 second high-speed auto focus (AF) with 315 focal-plane phase-detection AF points.

The device is capable of 4K movie recording with tiltable LCD screen, housing "Touch Focus" and "Touch Pad" features.

Building on the success of last year's RX10 III, the new camera features up to 24 frames per second (fps) continuous shooting with full AF/AE tracking.

It has 315 phase-detection AF points that rivals the fastest professional interchangeable lens cameras, the company said in a statement.

The RX10 IV model delivers an unmatched combination of mobility and speed for imaging enthusiasts and professionals looking for the ultimate 'all-in-one' solution.

For the first time in a Cyber-shot camera, the RX10 IV model employs "High-density Tracking AF" technology.

This advanced technology concentrates AF points around a subject to improve tracking and focus accuracy, allowing even the most unpredictable subjects including fast-moving athletes and birds in-flight to be captured with ease.

For convenience during image playback, continuously shot images can be displayed in groups instead of individual shots.

The RX10 IV also has a high-speed "Anti-Distortion Shutter" (maximum shutter speed of up to 1/32000 second) that reduces the "rolling shutter" effect commonly experienced with fast moving subjects.

It helps shoot silently in all modes -- including continuous high-speed shooting -- when the electronic shutter is engaged.
A mechanical shutter mode is also available as well if required by the user, the company said.
