Low-Light 12.1MP Full-Frame Mirrorless Camera

The Sony Alpha a7S III uses a 12.1MP Exmor R back-illuminated full-frame sensor paired with the BIONZ XR processor to deliver clean images up to ISO 409600 and UHD 4K 10-bit 4:2:2 video at up to 120p. A 759-point Fast Hybrid AF system and a world-first 9.44m-dot OLED electronic viewfinder support precise composition and focus in demanding conditions.

Video Professionals and Low-Light Specialists

This camera suits creators who need high-frame-rate 4K 10-bit internal recording, 16-bit RAW video output via HDMI, and extreme low-light sensitivity for events, documentaries or cinema work. Photographers who prioritise high-resolution stills for large prints or heavy cropping should consider a higher-megapixel body instead.

12.1MP Sensor Resolution Decides Fit

The 12.1MP full-frame sensor determines whether the camera meets your still-image detail requirements; it favours low-noise performance and fast readout over maximum pixel count. Buyers who need more megapixels for landscape, studio or archival work will need a different sensor resolution.

Questions about this item

What comes in the box with the Sony Alpha a7S III and do I need to buy a memory card or battery separately?

The camera body is supplied new in its original packaging. A rechargeable battery and charger are included. Memory cards are not included and must be purchased separately to record 4K 10-bit 4:2:2 video at up to 120p.

Should I choose the 12.1MP full-frame model or a higher-resolution version for low-light video up to ISO 409600?

The 12.1MP Exmor R BSI sensor is optimised for sensitivity and readout speed. Its larger pixels deliver cleaner low-light performance up to ISO 409600 and enable full-pixel 4K 120p 10-bit recording without crop.

What does the 9.44m-dot OLED electronic viewfinder resolution mean when I am composing 4K 120p footage?

The 9.44 million dot OLED panel provides a high-magnification, high-refresh view with minimal lag. It allows precise manual focus and exposure judgement while recording 4K 10-bit 4:2:2 at 120p.
