Panasonic Lumix GH6
The Panasonic Lumix GH6 succeeds the GH5, which was able to set new standards in the field of photo-video hybrid cameras in 2017. For instance, the predecessor was the first to bring 4K video at 60 fps to affordable consumer cameras - almost exclusive for many years.
In addition to the improved color science, the completely renewed image processor primarily offers more computing speed. While you had to choose between either 50/60 frames/s or 10-bit color depth in 4K resolution with the Lumix GH5, the Lumix GH6 allows for the higher-quality 4:2:2 10-bit up to 60 fps. Alternatively 120 frames/s in 4K or 60 frames/s in 5.7K resolution (4:2:0 10-bit each). For slow motion, Full HD videos with up to 300 fps can be recorded, also with 10 bit color depth.
Besides that, there are many detail improvements like a dedicated audio menu including the corresponding button, a tally light or the option to filter the various video-codec-resolution-frame-rate-combinations. Of interest for photo and video: The image stabilizer can now compensate up to 7.5 EV according to CIPA standards in Dual I.S. mode.
Which memory cards for the Lumix GH6?
Like the first generation, the Panasonic Lumix GH6 also has two memory card slots. However, now one each for SD and CFexpress memory cards each, whereby the latter are the means of choice for video recordings: Bit rates of over 600 Mbit/s are only possible with CFexpress memory cards. This includes slow motion recordings with 240 fps in All-Intra encoding as well as all 5.7K formats in Apple ProRes 422 (HQ).
Panasonic has further already announced a firmware update for the future that will unlock the USB-C port for recording on USB-C SSDs that offer a much better price/performance ratio.
In the case of continuous shooting, a whopping 75 fps in full quality settings (RAW) is possible with the Panasonic Lumix GH6, but then limited to single autofocus (AF-S) and 200 frames or just under three seconds respectively. With autofocus tracking, 8 frames/s are possible. No matter in which settings: Speed records, such as the Nikon Z 9 with about 1 GiB/s effective write rate recently, are not achieved by the Panasonic Lumix GH6. The CFexpress controller limits at about 250 MiB/s.
