The Sony FDR-AX53 is a palm-sized Handycam camcorder that combines a Zeiss 20x optical zoom lens and a high-sensitivity image sensor to produce crisp and high-quality UHD 4K video. The Exmor R CMOS image sensor supports UHD 4K video capture at 24 or 30 fps using Sony's XAVC S codec and features pixels that are approximately 1.6x larger than the previous model for enhanced performance in all conditions, particularly low-light scenarios. The camcorder also features Sony's Balance Optical SteadyShot image stabilization technology to help produce smooth and stable footage throughout the zoom range. Further enhancements include improved autofocus speed and accuracy, a lower-noise built-in microphone, and a high-speed 1080p 120 fps recording mode to create high-resolution slow-motion content.
