Introducing the Alpha 7S III – a new milestone in sensitivity, speed and image supremacy. Featuring an all-new 12.1MP1 backside illuminated full-frame sensor with twice the readout speed* for ultra-clean low-light images up to ISO 409,6003 with 15+ stops dynamic range4 and 3x reduction in rolling shutter, plus Sony’s acclaimed fast hybrid autofocus with 759 phase detection AF points. A new BIONZ XR processing engine deliver 8x more processing power2 for up to 120p5 4K 10-bit 4:2:2 and full pixel readout in all recording modes.
Sensitivity, speed and supreme imagery
The Alpha 7S III features a newly developed 12.1-megapixel1 Full-frame Backside-illuminated (BSI) Exmor R CMOS sensor that delivers sensitivity, speed and superior images and movie. It takes full advantage of the large pixels and BSI copper wiring structure to more than double the sensitivity and readout speed2. The results are astounding, with phenomenal low-light capability, up to 15+ stops of dynamic range4 and drastically reduced noise for ultra-sharp and clean images and 3x reduced rolling shutter2. In addition, this new Exmor R sensor features Sony’s acclaimed fast hybrid autofocus with 759 phase detection AF points and 92% coverage. The high sensitivity also allows it to autofocus in light as low as EV-611.
