Waveform of the Xyla21 stepchart for the Panasonic LUMIX S5 at ISO 640 V-Log in UHD 25p mode. Around 12 stops can be identified above the noise floor.
IMATEST dynamic range result for the Panasonic LUMIX S5 at ISO 640 V-Log in UHD 25p mode. 12.1 stops are calculated at a signal to noise ratio of 2.
ISO 4000 / V-Log時のダイナミックレンジ
ISO 4000でも、非常に似た結果が得られた。SNR= 2で11.9ストップ。ここでも、波形は13番目と14番目のストップがノイズに埋もれている。

LUMIX S5 in UHD, V-Log, 25p, ISO 640 four stops underexposed and pushed back. Getting noisy, but the noise is very finely dispersed and can be effectively removed by noise reduction.
LUMIX S5 in UHD, V-Log, 25p, ISO 640 four stops underexposed and pushed back, noise reduction applied (3 frames temporal, threshold = 10). Again the shape of the iris of the SIGMA 45mm 1:2.8 is visible.
LUMIX S5 in UHD, V-Log, 25p ISO 640 five stops underexposed and pushed back. The image falls apart but even without noise reduction it still looks surprisingly good. Horizontal stripes appear in the image, however.
LUMIX S5 in UHD, V-Log, 25p, ISO 640 5 stops underexposed and pushed back, noise reduction applied (3 frames temporal, threshold 20, spatial threshold 2). Horizontal stripes appear in the image. But it still looks surprisingly good.
Fascinated by the new possibilities with small cameras. Passionate shooter who isn't doing this for a living. Cut my teeth on the Panasonic GH series, always looking to keep the gear as small as possible on my travels through the world, where I am telling cinematic stories as a hobby.
