CineD tested the Sony A7rVI: Highest DR ever tested (with a caveat) and promising prospects for the A7sIV :)
SonyAlphaRumors • • technology
Key Points:
- Sony's a7R VI camera delivers impressive rolling shutter performance and dynamic range, achieving up to 14 stops at SNR=2 with dual gain mode enabled, the highest measured so far.
- Despite strong lab results, real-world testing in CineD’s studio reveals limitations in the 10-bit internal codecs, capping exposure latitude at around 9 stops and falling short of the LUMIX S1II's performance.
- In 8K mode, where dual gain is unavailable, exposure latitude drops further below 9 stops, highlighting the significance of Sony’s dual-gain technology.
- The a7R VI's dual-gain implementation suggests promising advancements for future Sony models, particularly the anticipated a7S series.
