Panasonic introduced the new hybrid Digital Single Lens Mirrorless Camera LUMIX GH5S with expanded video recording capability and enhanced image quality. Designed and developed for professional filmmakers, the LUMIX GH5S achieves highest-ever image sensitivity and video image quality in the history of LUMIX cameras, especially in low-light situations. The new 10.2-megapixel Digital MOS Sensor with Dual Native ISO Technology and Venus Engine 10 faithfully reproduce even dark parts of the image, allowing high ISO capture when the use of supplemental lighting may not be possible. This sensor is a multi-aspect type with a sufficient margin for realizing the same angle of view in 4:3,17:9,16:9 and 3:2 aspect ratios. The sensor also enables photo shooting in 14-bit RAW format, providing higher flexibility for professional RAW stills development workflows. When shooting in dark environments, videographers can now focus on filming that perfect shot as they no longer need to worry about noise which often results from having to use higher ISOs. The Dual Native ISO Technology suppresses noise to produce cleaner footage when taken in all light. Both videographers and photographers can now enjoy the same diagonal field of view across all aspect ratios with the True "Multi-Aspect Ratio" Function. This feature means you can easily swap between difference aspect ratios giving you the accuracy you want from your lenses, and making the process easier while producing and editing in post-production. The LUMIX GH5S is compatible with Time Code IN and OUT, like the professional camcorders, which is easy to set using the flash sync terminal and bundled conversion cable for a standard BNC terminal. This is especially important for "lip synchronization" when using multiple cameras. The LUMIX GH5S can be used as Time Code generator for other GH5S cameras and professional camcorders. The Time Code IN/OUT functionality makes a production teams job pain-free as it provides synchronization for both video and audio devices used on multi-cam productions. The LUMIX GH5 achieved 4KUHD 60p video recording for the first time as a digital mirrorless camera in 2017.2 The new LUMIX GH5S establishes a new milestone by realizing the world's first 4K 60p video recording in Cinema 4K (4096x2160), 3 capable of internal 4:2:2 10-bit video recording up to Cinema 4K30p and internal 4:2:0 8-bit Cinema 4K60p. This is a color subsampling commonly used for film production, for even more faithful color reproduction. The LUMIX GH5S also records 4:2:2 10-bit 400-Mbps All-Intra in 4K 30p/25p/24p and 200- Mbps All-Intra in Full-HD. Continuing the LUMIX GH tradition, there is no time limit for both Full-HD and 4K video recording. The LUMIX GH5S complies with 4K HDR video with Hybrid Log Gamma (HLG) mode in Photo Style. A low-bit-rate recording mode, 4K HEVC for HLG, is available. This enables playback on AV equipment compatible with the HLG Display format, such as Panasonic 4K HDR TVs. The VFR (Variable Frame Rate) function lets users record overcranked (time-lapse) and undercranked (slo-mo) video in C4K/4K (60 fps, maximum 2.5x slower) and FHD (240 fps, maximum 10x slower). A V-LogL and Rec.709 LUT (Look Up Table) are pre-installed in the camera, so users can play videos recorded in V-LogL without having to separately purchase a Software Upgrade Key. Four additional LUTs can be installed using the Panasonic Varicam (.VLT) file format. DFD (Depth From Defocus) technology and ultra-high-speed digital signal processing achieve fast auto focusing of approximately 0.07 sec 6 with 12 fps (AFS) /8 fps (AFC) in 12- bit RAW and 10 (AFS) /7 (AFC) fps in 14-bit RAW high-speed burst shooting. In addition to a total of 225 focus areas, The options for Face/Eye Recognition, Tracking AF, 1-area AF and Pinpoint AF are available for precise focusing. The 4K PHOTO enables 60 fps high-speed capture in approximately 8-megapixel equivalent resolution.
