First Look at the Panasonic GH5S

CES 2018 is here and Panasonic has just unveiled its new flagship low light camera – the (long rumored) GH5S. This new model will not replace the GH5 but will exist alongside it as a more specialized camera.

The GH5S is very similar to the existing GH5 (externally there is almost no difference apart from the red writing on the front). The difference between the two is mostly internal and has to do with the sensor which is of much lower resolution and has no built-in image stabilization like the GH5 but on the plus side has a much improved dynamic range and even more so – sensitivity. Other than that maybe the only major difference is the shooting speed in video – the GH5S is capable of 1080p up to 240fps (and should be better overall. 4K still max out at 60p). Last thing – Panasonic claims the GH5S also improves the AF – but this will need to be tested independently before we can say anything about that.

Here are some of the specs of the GH5S (we marked the changes from the GH5 – there are quite a few smaller ones):
