Customer Reviews
The Alpha a6400 from Sony is an APS-C-format mirrorless camera that adopts many of the features normally reserved for their full-frame lineup. The a6400 is well-suited for both photo and video creators, ranging from professionals to vloggers. Revolving around a 24.2MP Exmor CMOS sensor and BIONZ X image processor, clean image quality is provided with a wide expandable sensitivity range of ISO 100 to 102400, along with accelerated readout speeds for internal 4K24 and Full HD 1080p120 video recording with full pixel readout. Stills shooters also benefit from the processing speed, which enables continuous shooting at 11 fps for up to 116 JPEGs, 46 raw images, or 44 raw and JPEG frames in a burst, as well as 14-bit raw file output. Furthermore, Real-time Tracking uses AI-based object recognition and processes color, subject distance (depth), and pattern (brightness) as spatial information to ensure that all subjects can be captured with accuracy. A rear 3.0″ 921.6k-dot touchscreen TFT LCD monitor is also available and tilts 180° up and 74° down to benefit shooting from high and low working angles. The touchscreen design also allows for intuitive touch-to-focus control. This high-speed, high-performance tracking AF system is paired with a BIONZ X image processing engine that together allows the camera to acquire focus in as little as 0.02 seconds and maintain subject lock effectively, ensuring even the fastest moving subjects can be tracked and captured with ease. Additionally, when photographing or videographing humans or animals, face and eye position information are recognized by AI and the subject’s eye is monitored in real-time with high tracking precision. This can be activated by a simple half-press of the shutter button or can be assigned to a custom function
