Highlights

a7S III

Low Light Performance: 12.1MP Exmor R BSI CMOS sensor excels in extreme darkness with ISO 80–102400.
Video Capabilities: Full-frame 4K 120p internal recording with 15 stops of dynamic range.
Reliability: Proven workhorse for demanding video productions, known for stable performance.

a7 V (Alpha 7V)

Resolution & Detail: 33MP partially stacked Exmor RS CMOS sensor delivers 7K oversampled 4K and high-resolution stills.
Autofocus System: Real-time Tracking AF with AI-based subject recognition and 759 phase detection points.
Hybrid Versatility: Balances high-res stills with strong video features like 4K 60p full-frame and 4K 120p (APS-C).

The trade-off

Choosing the a7S III means giving up the higher resolution 33MP sensor and the latest AI-driven autofocus system. Choosing the a7 V means sacrificing the superior low-light performance of the 12.1MP sensor and its 15 stops of dynamic range.
