DxOMark published their Panasonic Lumix DC-GH5 sensor review and test results: The new Panasonic Lumix DC-GH5 Micro Four Thirds mirrorless camera achieved an excellent overall DxOMark sensor score of 77 points, with a combination of 23.9 bits color sensitivity, 13 EV dynamic range, and 807 ISO low-light score – the Panasonic GH5 is the best performer in the lineup.
The Panasonic Lumix DC-GH5 features a 20-MPix sensor, presumably the same or a related sensor adopted by other high-end models such as the maker’s DMC-GX8 and the rival Olympus EM-1 Mark II. So it will come as no surprise to learn that it delivers scores that are among the best-in-class for this size sensor.
Panasonic Lumix DC-GH5 vs Olympus OM-D E-M1 Mark II vs Panasonic Lumix DMC-GX8
Comparing the image quality results of the Panasonic Lumix DC-GH5 with the high-end Panasonic DMC-GX8 and the Olympus OM-D E-M1 Mark II, we can see that although all three appear to share the same or a similar sensor, the Olympus may have adopted a slightly modified version, or at least tuned it to deliver slightly better results at higher ISOs. In our our Low-light ISO test, it delivered just over a half-stop advantage over the GH5 and GX8, and there’s a similar improvement (if slight in real terms) in dynamic range and color, at least at higher ISOs.
Conclusion from DxOMark:
Like its predecessor the GH4, there’s no doubt the Panasonic GH5 is oriented toward videographers, but there’s still plenty to like about the camera for stills use. In spite of the increase in pixel count to 20-MPix, noise remains at the same level as the earlier 16-Mpix GH4. Even when compared to the maker’s GX8 that uses a similar 20-MPix sensor, the GH5 has slightly improved dynamic range and color sensitivity.
