The LUMIX GH5S achieves the highest ever sensitivity and best image quality in LUMIX history. This is realized by combining the newly developed high sensitivity sensor with Dual Native ISO technology and the latest Venus Engine.
Dual Native ISO is a s revolutionary technology featured on Panasonic's professional video cameras and offers the advantages of very high sensitivity while keeping noise levels low.
Usually, with a conventional single native ISO, noise levels rise when sensitivity is increased. However, the newly developed image sensor implements dual circuits able to switch to high native sensitivity before gain processing. This means you can achieve beautiful footage with suppressed noise in low lit situations.
The LUMIX GH5S sensor handles multiple aspect ratios; 4:3, 17:9, 16:9 and 3:2. Thanks to broad margins of effective pixels, focal length does not change in these aspect ratios.
Rolling shutter distortion, compared to the GH5, is suppressed by aprrox. 1.3x with high readout speeds when recording video or using an electronic shutter.
The superior sensor saves super detailed RAW files in 14bit RAW data to give photographers a wider range of expressive options.
The LUMIX GH5S realized -5EV luminance detection perfromance with Low Light AF. The Live View Boost function is also added so you can clearly monitor and compose your subject when shooting in dark situations. 20x Manual Focus Assist is also useful for night sky photography, making it possible to focus on a single start by enlarging it.
The original LUMIX GH5 made it possible to record 4k/60p and 4k/50p video on a DLSM camera. Now, to greatly extend your creative possibilities, the LUMIX GH5S takes this even further and for the first time ever**, includes 4,096 x 2,160 Cinema 4K 60p/50p* video recording. Moreover, there no limit*** to the recording time, not even when shooting FHD or 4K video. * Cinema 4K (C4K: 4096 x 2160) resolution defined by Digital Cinema Initiatives (DCI).
** As of January 8, 2018 as a Digitil Single Lens Mirrorless camera that complies with Cinema 4K (C4K: 4096 x 2160) resolution defined by Digital Cinema Initiatives (DCI). According to a Panasonic study.
*** Subject to SD card capacity and battery life.
With internal recording of video in 4:2:2 10bit* and an impressive 10.2 megapixel Digital Live MOS Sensor backed by a Venus Engine that handles digital signals at ultra high speed, this camera's image quality per frame is dramatically improved with faithful colour reproduction and grading. High bit rate recording at 400Mbps, optimal for nonlinear editing, is also made possible. * 4:2:0 8bit in C4K 60p/50p and 4K 60p/50p recording on an SD Memory Card.
The LUMIX GH5S complies with 4K HDR video. The HDR (High Dynamic Range) is a mode to reproduce both bright parts and dark parts of an image, making the subject appear just as the human eye perceives it. The camera records video with a designated gamma curve compatible with ITU-R BT.2100, and you can now choose Hybrid Log Gamma (HLG) in Photo Style. A low bit-rate recording mode 4K HEVC for HLG is also available, which enables playback on AV equipment compatible with the HEVC compression format, such as Panasonic $K HDR TVs.
The V-LogL is pre intalled in LUMIX GH5S. Log recording offers exceptional flexibility as well as a wider dynamic range for colour grading in the post production process and V-LogL features log characteristics with 12 stops of dynamic range. By default, the Look Up Table (LUT) data is Rec.709 standard. LUT can also be custom set for VLT format in camera. Then, with the V-LogL View Assist function, you can preview what your footage may look like after it's been post processing.
Shooting with an anamorphic lens and using the fullest extent of the 4:3 sensor the camera's built in 4:3 anamorphic mode makes it possible to create video in the cinemascope format. Stunning cinemascope videos are created in post production using dedicated software but the de-squeezed cinemascope images can also be previewed while recording, or in playback, on the camera display.
To elevate video expressivity even further, a variety of effects are available on the LUMIX GH5S. The VFR (Variable Frame Rate) lets users record overcranked / undercranked video C4K/4K (60fps, maximum 2.5x slower**) and FHD (240fps, maximum 10x slower**). The minimum frame rate for quick motion effects video is 2fps. * The degree of effect varies depending on the recording format and frequency and angle of view narrows if you select a frame rate with a number of frames 204 or more.
