Panasonic have just announced the GH5s, an update to their flagship GH5. The new camera – out in April – is specifically aimed at professional video shooters. It adds more video options to the GH5’s already impressive specs, with impressive low light performance.
Panasonic have designed the GH5s around a new sensor. The 10.2 MP sensor has around half as many effective pixels as the GH5. This makes a lot of sense for video shooters, particularly with small MFT sensors: as each pixel is bigger, it can capture more light.
This sensor is multi-aspect. Other cameras have a ‘native’ aspect ratio which they crop for different frame shapes: the GH5s has a bigger sensor which can accommodate different frame shapes without cropping. Apart from maximising image quality and low-light performance, this means you get the full benefit of wide angle lenses whichever aspect ratio you’re using.
It’s also dual-gain. You can switch between two different modes depending on how much light you have. Normal mode is based on getting the best dynamic range (the amount of contrast the camera can handle); in low-light mode the priority changes to reducing image noise.
But the new sensor lacks the GH5’s impressive in-body image stabilisation. That’s because most pro users will mount the camera on a tripod, cranes or stabilisers, and in-body stabilisation makes the original GH5 prone to jitters when used in situations with a lot of vibration.
Other new pro features include timecode in and out, and the ability to shoot full ‘digital cinema’ 4K in slow motion and at PAL and NTSC television frame rates. It also includes V-log. This option – a paid add-on for the GH5 – makes contrasty scenes easier to film and to correct at the editing stage. It can also shoot HD video at up to 240fps. Autofocus is improved over the GH5.
The GH5s is out in April at around $2500/£2200 body only. You can pre-order it now.
