Imagination in Motion

Responding directly to the needs of today’s content creators, Sony’s S series is

back with a refined sensor and imaging processing engine that deliver even

greater sensitivity and dynamic range, plus unprecedented speed and

processing power for dramatically expanded creative scope. In addition to

sensitivity and speed that can only be achieved with big pixels on an advanced

full-frame 12.1 megapixel

sensor, the α7S III offers 4K movie recording at up to

120p, with stunning 10-bit depth and 4:2:2 sampling when needed. It achieves

this while maintaining the compact mobility and extraordinary focal plane

phase-detection AF performance that have made Sony’s E-mount α series a

favorite with creative professionals. The α7S III also offers updated control

capabilities and fast response that, in combination with supreme image quality,

make it easier than ever to bring your imagination to life.
