Color reproduction by the Sony Alpha 7 Mark III is accurate, with only one color showing a strong deviation from the original. ∆E ranges from 8.9 at ISO100, to a small range between 9.7 and 10.0 at ISO400 to ISO 1600.
Photo: The automatic white balance implemented by the Alpha 7 Mark III is excellent, with values between 0.0 and 0.2 at all ISOs measured between ISO100 and ISO25600.
Video: Automatic white balance is not excellent, with scores of 1.5 (low ISO) and 1.4 (high ISO).
Just for the record - DR:
Photo: The dynamic range exhibited by the Alpha 7 Mark III is very good: over 10.1 f-stops (up to 10.3) at all ISOs tested between ISO100 to ISO800. Dynamic range remains high as ISO increases (9.8 f-stops at ISO1600) up to ISO6400 (9.2 f-stops). However, once again, ISO12800 shows poorer results, with a drop of nearly a full f-stop to 8.3. The extended ISOs are even worse: for example, 6.9 f-stops at Hi1.
Video - Dynamic range is good: 9.0 f-stops at low ISO and 8.0 at high ISO.
EOS R:
Color reproduction is good, with only 6 colors deviating strongly, five of which are reds. ∆E is consistent and ranges from 10.3 to 10.6 at all ISOs tested.
Photo: Automatic white balance is very good, ranging between 0.3 and 0.6 at all ISO s tested from ISO 100 to ISO 12800.
Video: Automatic white balance is decent at high ISO (0.7) but poor at low ISO (1.2). Color reproduction is nearly as good as in still images, with a ∆E of 11.7 at both high and low ISO .
Just for the record - DR:
Photo: Maximum dynamic range: 14.1 f-stops measured at ISO 800. Dynamic range is more than 10 f-stops at all ISO s from ISO 100 up through ISO 3200. At ISO 100, dynamic range is measured at 10.9 f-stops, at ISO 400 12.9, and at ISO 1600, 11.0. Dynamic range is poorer at the higher ISO s, with a minimum tested among the native ISO s, or 7.9 f-stops at ISO 25600.
Video: Dynamic range is good in video (9.7 and 9.0 f-stops for low and high ISO , respectively). Automatic white balance is decent at high ISO (0.7) but poor at low ISO (1.2). Color reproduction is nearly as good as in still images, with a ∆E of 11.7 at both high and low ISO.
Conclusion:
Color Reproduction and Color "Beautyness" are two different shoes. And Auto White Balance makes a different, too. Imho, the 5 deviating reds and the better AWB is the key, why a lot of people might prefer canon colors over sony - in terms of video.
