Sony a7R VI Lab Test: Impressive Dual-Gain DR, But Latitude Falls Short
CineD’s lab test of the Sony a7R VI shows the camera’s dual-gain mode delivering strong dynamic range (up to 14 stops at SNR 2 in 4K DG ON) and very fast readout when DG is OFF (7.2 ms, 15.6 ms with DG ON in 4K), with 8K 25p lacking DG at 13.5 ms. The 8K/SGamut cines-S-Log3 test yields about 11.4 stops at SNR 2 and 12.6 at SNR 1, while the 4K DG ON latitude reaches around 13–14 stops in IMATEST terms, but real-world latitude tops out around 9 stops and struggles at 10 stops due to the camera’s 10-bit internal codec (no 12-bit RAW like some competitors). In short: strong DR and rolling-shutter performance, but latitude doesn’t yet dethrone the Lumix S1 II in practical testing.
