Panasonic at CES 2018 has launched an upgrade to the Panasonic GH5, and while the latter does everything so well for the videography, the Panasonic GH5s mirrorless camera takes it ahead with further improvements and developments aimed at videographers. The GH5s has half the resolution of the GH5, with the presence of a 10.2-megapixel dual ISO sensor.
The change in sensor gives it a better low-light sensitivity, i.e. up to ISO 51200 native and 204800 extended, and the readout is of full sensor at up to Cinema 4K resolution at 2160 x 4096 pixels at 60 frames per second. The dual native ISO works with two circuits in the system where the slower circuit turns off when you hit 2500 ISO and the faster circuit starts itself, which helps in reducing noise and thus, the details in the picture in low light are retained.
Now, the main point about the camera is its video capabilities. The GH5s can record 10-bit, 4:2:2 video captured at data rates as high as 400 Mbps (50 MB/s). That is equal to an HDR video and the HDR output is possible through the HDMI 2.1 port.
The camera also has some pro-video features, but one thing that Pansonic has changed and will be this – “We’re targeting the videographer and not the photographer,” said Hanna. “So that’s we we decided to eliminate IBS.” says Panasonic product manager Anthony Hanna. That means the camera will have no in-body stabilization (IBS) system and thus, you will need to have lenses with optical stabilization in case the video stability is needed.
For the photography, there is support for 14-bit RAW. Also, the Panasonic GH5s giving focus speeds of 0.07 seconds, the burst shoots can be done at 12 fps and with continuous autofocus, it can be done at 8 fps. A couple of additional photo options include 225 focus points, face-eye recognition, and 4K photo mode at up to 60 fps.
The Panasonic GH5s has two UHS-II SD memory card slots, USB 3.1 Type-C port, Wi-Fi and Bluetooth connectivity. The GH5s is priced at $2,499 and that is about $500 more than the GH5, but it matches the price of the rival Sony A7S II.
