Alpha ILCE-7R IIIA with 35 mm full-frame image sensor
Inspiring maximum creativity
Welcome to a new world of imaging with resolution, sensitivity, dynamic range, processing speed and shooting response further enhanced. The α7R III packs pro-style operability into a strong, compact body to give you greater flexibility to take brilliant shots in any situation. With such high power, precision and potential at your command, you can capture once-in-a-lifetime experiences.
A portal to unseen worlds
Together, an effective 42.4MP (approx.) image sensor and enhanced image processor can take imaging as far as adventurous imaginations allow.
Seize moments with quick precision
Doubled AF tracking effectiveness, even during continuous shooting at up to 10 fps, advances the evolution of steady, lightning-fast camera performance.
42.4 MP full-frame Exmor R™ CMOS sensor
The Exmor R sensor's back-illuminated, gapless on-chip lens design increases light sensitivity and provides wide dynamic range, despite its high resolution of 42.4 MP.
Greatly enhanced image processing
A new front-end LSI and BIONZ X™ boost processing speed are teamed with the Exmor R™ sensor to deliver up to 15-stop dynamic range at low ISO sensitivity for stills, enabling richer tonal expression.
14-bit RAW output for rich gradations
14-bit RAW format output contains rich tonal information from highlights to shadows, and is available even when shooting in silent or continuous mode.

 The latest high-speed front-end LSI
 16-bit image processing
Shoot continuously in absolute silence
This camera allows silent shooting at up to 10fps with AF/AE tracking. Silence is critical for shooting wildlife, when even slight noise can mean missing a chance at an ideal shot.
SuperSpeed USB 5 Gbps (USB 3.2) for fast data transfer
This makes PC-tethered shooting available for smooth handling of big RAW image files, so you can quickly review images on a PC and continue shooting without too much delay for file transfers.
AF tracking improved by approx. 2x
The AF algorithm inherited from the α9 accounts for two times more precise AF tracking for continuous shooting, even of complex or sudden movement.
SPECIFICATIONS AND FEATURES
An entirely renewed image processing system further enhances image quality. Up to approximately 2x improved AF speed14, AF tracking6, and Eye AF tracking6performance and up to 10fps continuous shooting allow more decisive moments to be captured. Reliable pro-style operability packed within a strong, compact body provides superior flexibility and mobility.
