1. Highest sensitivity and image quality in the history of LUMIX cameras with a new sensor
        The new LUMIX GH5S was developed to pursue the highest picture quality in high sensitivity video recording by newly integrating a 10.2-mega effective pixels Live MOS Sensor with Dual Native ISO technology and the latest Venus Engine. Dual Native ISO is a technology that seamlessly bridges two circuits of separate native ISO, which is used in Panasonic Varicam models for professionals. Normally, noise increases as sensitivity rises with a single native ISO image sensor, however, the new image sensor with Dual Native ISO in GH5S minimizes noise generation by choosing an optimal circuit to use according to the sensitivity before gain processing. As a result, it allows a maximum ISO 51200 high sensitivity recording. This Dual Native ISO technology can be switched manually between LOW(ISO160-800) and HIGH (ISO800-51200)
        This sensor is a multi-aspect type with a sufficient margin for recording the same angle of view at the same focal length in C4K, 4K, Anamorphic 4:3 in video recording, and 4:3,3:2, and 16:9 aspect ratios in photoshooting.
        The High Sensitivity MOS Sensor and Venus Engine realize a high-speed readout of full digital signals and the image quality is outstandingly high for every single frame. The signal readout speed is accelerated by approximately 1.3x* in the new Digital Live MOS Sensor and rolling shutter is also suppressed with the high readout speed when recording video or using an electronic shutter.
        The sensor also supports photoshooting in 14-bit RAW format, providing higher flexibility for professional RAW development workflows.
* In comparison with LUMIX GH5.

2. Outstanding video recording performance to meet professional standards
        The LUMIX GH5 achieved the world’s first*¹ 4K 60p / 50p video recording as a Digital Single Lens Mirrorless Camera and the new GH5S further enables C4K 60p / 50p video recording*². It is also capable of internal 4:2:2 10-bit video recording*³, which is a color subsampling commonly used for film production, for faithful color reproduction. Users can freely choose the format from MOV, MP4, AVCHD Progressive and AVCHD at a variety of frame rates according to the usage [Figure#1] and there is no recording time limit*⁴ for both Full-HD and 4K video. The LUMIX GH5S also records 4:2:2 10-bit 400-Mbps All-Intra in Cinema 4K 24p and 4K 30p/25p/24p and 200-Mbps All-Intra in Full-HD. For the global needs of professional users, the system frequency can also be flexibly selectable between 59.94Hz / 50.00Hz / 24.00Hz. The LUMIX GH5S complies with 4K HDR video. The HDR (High Dynamic Range) is a mode to reproduce both bright part and dark part in an image, making it look just as human eyes see. 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. This mode can be used not only in 4K/FHD but also in any 10-bit recording modes. 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 4K HDR TVs.
        To elevate the video expression even more, a variety of effects are available on the LUMIX GH5S. The VFR (Variable Frame Rate) lets users record overcranked / undercranked video in C4K/4K (60 fps, maximum 2.5x slower in 24p) and FHD (240 fps, maximum 10x slower in 24p) [#Figure2]*⁵. The minimum frame rate for quick motion video is 2 fps. A Focus Transition function is available, which moves the focus from subject to subject as set in advance automatically. It can add visual guidance to the target subject or motion on the static scene.
        The V-LogL is pre-installed in the LUMIX GH5S. Log recording offers exceptional flexibility as well as a wider dynamic range for color grading in the post-production process, and V-LogL features log characteristics with 12 stops of dynamic range. LUT (Look Up Table) with Rec.709 standard is available in the camera by default, and users can also customize the LUT in VLT format. It is possible to see the video footage with LUT applied, not only in live view but also in playback with the V-LogL View Assist function.While “Cinelike D” and “Cinelike V”, which have similar gamma setting characteristics for film production, are available in Photo Style for video recording, the LUMIX GH5S provides "Like709" for compatibility with HDTV. In "Like709", Knee Control is also effective. Now V-LogL and Like709 can be used for interval photoshooting in Time Lapse Shot mode.
        The LUMIX GH5S is compatible with Time Code IN/OUT synchronization through the flash synchro terminal and bundled BNC converter cable with BNC cable. This makes the non-linear editing of footage shot with multiple cameras easy. LINE input is also supported by a 3.5mm microphone jack. This makes it possible to input sounds from an external audio device, for more efficient video production.
        Practical tools like Waveform Monitor and Vector Scope are also available. For the terminal, HDMI Type A is provided. Plus, a cable lock holder for the HDMI cable is included in the LUMIX GH5S to prevent unplugging trouble on location.
        In addition, the LUMIX GH5S incorporates a dedicated microphone to monitor and cancel the noise caused by mechanical movements inside the camera and lens. The result is a reduction of mechanical noise by -10dB, achieving clear, high-quality sound recording.

3. High-speed, high-precision AF and excellent tracking performance
        The DFD (Depth From Defocus) technology*¹ calculates the distance to the subject by evaluating 2 images with different sharpness levels while instantly consulting the optical characteristics data of the current lens. Panasonic’s combination of the Contrast AF with DFD technology achieves high-speed, high -precision auto focusing. Consequently, the LUMIX GH5S realizes a high-speed AF of approximately 0.07 sec*² and 12 (AFS) / 8 (AFC) fps in 12 bit RAW and 11 (AFS) / 7 (AFC) fps in 14 bit RAW high-speed burst shooting. This DFD technology further advanced for LUMIX GH5S to provide higher precision tracking performance in video recording.
        As a camera that excels in low-light shooting, the LUMIX GH5S boasts -5EV luminance detection performance with Low Light AF thanks to the higher sensitivity and optimized tuning of the sensor. Thanks to the high processing performance of the Venus Engine, the LUMIX GH5S incorporates Deep Learning technology that detects a human body in addition to the conventional face and eye detection. In addition to a total of 225 focus areas, Face/Eye Recognition, Tracking AF, 1-area AF and Pinpoint AF are available for precise focusing. Users can make a group of 225 focus areas and move or change the size of it as they like according to the composition. All focusing operations are easily controlled with the joystick located on the thumb position without taking the eyes off of the subject even when using an LVF or releasing the finger from the shutter button. The LUMIX GH5S is equipped with AF Custom Settings with which users can set AF Sensitivity, AF Area Switching Sensitivity and Moving Object Prediction Level. Four patterns of presets parameter are also available for frequently used situations.
        The 4K PHOTO enables 60 fps high-speed capture in approximately 8-megapixel equivalent resolution. In 4K PHOTO, three exclusive modes can be chosen from depending on the situation; 4K Burst, 4K Burst (Start/Stop) and 4K Pre-burst. Users can choose the most suitable burst shooting mode in addition to the regular consecutive shooting mode in full resolution depending on the situation.
        Live View Boost is another practical feature that makes it possible to check the composition even in total darkness by boosting the sensitivity just for live view. The magnification ratio in MF assist is increased from conventional the 10x to 20x, which is convenient for precise focusing on a tiny star in the sky in astronomical photography.
*¹ Contrast AF with DFD Technology works only with Panasonic Micro Four Thirds lenses.
*² In AFS, at wide-end with H-ES12060 (CIPA) in LVF120 fps setting.

4. Reliable rugged design for heavy field use
        To be tough enough to withstand heavy field use, the main structure is composed of a magnesium alloy full die-cast front/rear frame. Secure construction and a sealing for every joint, dial, and button make the LUMIX GH5S not only splashproof* and dustproof but also freezeproof down to -10 degrees.
        The shutter unit is also durable for approximately 200,000 cycles. It offers the highest shutter speed at max. 1/8000 sec not only to capture spur-of-the-moment, fast moving subjects and to use a high-speed lens with a fully open aperture even outdoors for impressive defocusing. The external flash can be synchronized with max.1/250 second shutter speed.
        The LUMIX GH5S is equipped with a double SD Memory Card slot compatible with high-speed, high capacity UHS-II and Video Speed Class 60. Users can flexibly choose the recording method from Relay Recording, Backup Recording or Allocation Recording. In Relay Recording, the data will be written on the SD Memory Card in the second slot when the SD Memory Card in the first slot is full. The content will be written in both SD Memory Cards in the first and second slot simultaneously in Backup Recording. In Allocation Recording, data is automatically allocated to the SD Memory Card in the designated slot by the type of content – RAW, JPEG, 4K PHOTO, or video data. For example, users can store only photos on the SD Memory Card in slot 1 and videos in slot 2. Moreover, both slots are equipped with access lamps so users can tell which SD Memory Card is under writing and which can be ejected at a glance.
        The LUMIX GH5S has a large LVF (Live View Finder) with a stunningly high magnification ratio of approximately1.52x / 0.76x (35mm camera equivalent). High-precision, high-speed OLED (Organic Light-Emitting Diode) display features 3,680K-dot high resolution and 100% field of view. Adoption of OLED for the LVF achieves smooth display at 120 fps and high speed response with minimum time lag of less than 0.005 sec as well as 10,000:1 high contrast for exceptional visibility. With an eyepoint of approximately 21 mm, it offers high visibility with comfort for users wearing glasses. It is always sharp and clear from the center all the way to the corners.
        Adopting a static-type touch control system, the 3.2-inch free-angle rear monitor in 3:2 aspect with 1,620K-dot high resolution features approximately100% field of view. It uses a pixel structure of RGB (Red / Green / Blue) and White to feature even higher visibility in sunny outdoor scenes. It tilts up and down by approximately270-degree which makes shooting at either high or low angles even easier. The LUMIX GH5S incorporates Night mode which provides mild backlighting. It lets the user watch the subject comfortably even right after viewing the monitor while in a dark situation for a long time.
