Just last month I went to visit Panasonic UK for a hands-on with the new Panasonic GH5S. My full review is in the pipeline but first an introduction to the new camera on the block…
The GH5S has a newly developed 10.2MP sensor for enhanced low light performance with Dual Native ISO technology, as well as 240fps 1080p S&Q.
For the first time since the GH2 this sensor is an over-sized 1.86x crop multi-aspect sensor. Possible for the first time is 60p at Cinema 4K resolution (4096 x 2160), whereas the GH5 is just Ultra HD 60p. The field-of-view will be slightly wider in Cinema 4K on the GH5S compared to the GH5 due to the larger sensor. The new CMOS also brings colour improvements with a new 14bit readout and less noise.
I got to play with the new Olympus E-M1 II today, a pro Micro Four Thirds camera they hope will sell for $2000. It certainly pulls out all the stops to imitate a miniature 1D X Mark II.
This camera does NOT crop the sensor in 4K mode like the GH4. Instead, it over-samples from 5K down to 4K, using the full width of the sensor even with sensor-shift 5 axis stabilisation enabled.
Featuring a 237Mbit codec, the image quality in Cinema 4K mode is outstanding with very little rolling shutter.
