Cinema-quality video recording performance
Outstanding video recording capability is the hallmark feature of the LUMIX S1H, making it an ideal professional tool for filmmaking.
The S1H contains a 24.2-megapixel 35mm full-frame CMOS sensor (35.6 mm x 23.8mm) that captures 6K resolution. With an active resolution of 6,024 x 4,016, the S1H delivers approximately 24.2 million photosites. OLPF adoption (Optical Low Pass Filter) suppresses moiré. In combination with optimum signal processing by the Venus Engine, it assures maximum ISO 51200 high sensitivity recording with minimum noise.
The distinguishing feature of the LUMIX S1H is dual-native ISO sensitivity, technology first introduced in the flagship VariCam line-up. It utilizes a process that reads the sensor in a fundamentally different way, extracting more information without degrading the image. This results in a camera that can switch from standard sensitivity to high sensitivity with almost no increase in noise or other artefacts. Dual Native ISO gives cinematographers a greater variety of artistic choices as well as the ability to use less light on set, effectively saving time. The LUMIX S1H’s Dual Native ISOs are 640 and 4000*1, which allow cinematographers to shoot in virtually any lighting environment. With a single native ISO image sensor, normally, noise increases as sensitivity rises; however, the new image sensor with Dual Native ISO in the S1H minimizes noise generation by choosing an optimal circuit to use according to the sensitivity before gain processing. The result is a maximum ISO 51200 high sensitivity recording. This Dual Native ISO technology can be switched manually between LOW (ISO 640-5000) and HIGH (ISO 4000-51200).
Maximizing the use of the pixels in the full-frame image sensor, the LUMIX S1H, as a digital camera, achieves for the first time ever a 6K/24p, 5.4K/30p (3:2 aspect ratio) or 5.9K/30p (16:9 aspect ratio) high-resolution, smooth video recording. It is also the world’s first full-frame digital interchangeable lens system camera to enable 10-bit 60p 4K/C4K HEVC video recording when using the image area equivalent to Super 35mm. The 4:2:2 10-bit 4K30p can record in H.264 at its full area. Its high-resolution data can also be used for creating 4K videos with higher image quality or for cropping images in 4K.
Dynamic range measures the luminance range that a digital camera can capture. The LUMIX S1H delivers more than 14 stops of dynamic range, which are virtually the same as those of the Panasonic Cinema Cameras, to precisely reproduce both dark and bright areas.
The ability to capture accurate colours and rich skin tones is essential for any filmmaker. With this in mind, Panasonic created the LUMIX S1H to import the renowned colorimetry of the VariCam lineup of cinema cameras. The LUMIX S1H contains V-Log/V-Gamut capture to deliver a high dynamic range and broad colours. V-Log renders a very flat image while maintaining all of the colour information within the image, so there is a greater level of play when the images are processed in post-production. The CMOS sensor of the LUMIX S1H achieves a wide colour gamut known as V-Gamut, which is the S1H’s optimum colour space and achieves a colour space that is wider than BT.2020. V-Log has log curve characteristics reminiscent of negative film, while V-Gamut delivers a colour space even larger than film.
HDR (High Dynamic Range) video recording is an option, which reproduces both the bright and dark parts of an image, creating images identical to how they are perceived by the human eye. The camera records video with a designated gamma curve compatible with ITU-R BT.2100, and the user can now choose Hybrid Log Gamma (HLG) in Photo Style.
The LUMIX S1H is capable of 4:2:2 10-bit 4K 60p/50p HDMI output. It accommodates a variety of recording formats, including 4:3 Anamorphic mode, to meet professional needs.
The VFR (Variable Frame Rate) lets users record overcranked or undercranked video in C4K/4K (60 fps, maximum 2.5x slower in 24p) and FHD (180 fps, maximum 7.5x slower in 24p). The minimum frame rate for quick motion video is 2 fps. In addition, HFR (High Frame Rate) video with sound can be recorded even when using auto focus. A variety of effects are available for producing a slow motion video in post-production..
Practical tools like a Waveform Monitor and V-Log View Assist are also available. Tally lights are equipped on both the front and rear sides for use in a multiple camera setup.
High reliability to support professional work
The LUMIX S1H integrates the Body I.S. (Image Stabilizer) for effective handshake correction. Panasonic developed an algorithm that precisely calculates shake information acquired from a gyro sensor, and image and accelerometer sensors. This enables more accurate shake detection and compensation, making it possible to use a 6-stop slower shutter speed. Combining the Body I.S. (5-axis) in the camera and the O.I.S. (Optical Image Stabilizer, 2-axis) in the LUMIX S Series lens, the 5-axis Dual I.S. 2 compensates for larger movements that were conventionally uncontrollable. Maximizing both O.I.S. and B.I.S. is highly beneficial in telephoto shots and in adverse situations, such as in low-light or with one-handed shooting with a 6.5-stop slower shutter speed. The 5-axis Dual I.S. 2 works for both photo and video recording, including 4K. The Body I.S. compensates for camera movement even when other L-Mount lenses without O.I.S. are used.
To achieve stable, continuous video recording, heat dispersion is crucial. Based on the accumulated study of heat simulation through the development of both professional cinema cameras and digital still cameras, Panasonic designed a cooling fan with an innovative structure that efficiently disperses heat exclusively for the LUMIX S1H to support its limitless video recording capability.
To be tough enough to withstand heavy field use, the main structure is composed of a magnesium alloy full die-cast top/front/rear frame. Robust construction and a sealing for every joint, dial and button make the LUMIX S1H not only splash-resistant and dust-resistant but also freeze-resistant down to -10 degrees Centigrade. The shutter unit is also durable for approximately 400,000 cycles.
High operability for intuitive control
The LUMIX S1H employs three large, high-resolution display devices for smooth confirmation of images on the spot.
The 3.2-inch, 2,330K-dot in 3:2 aspect rear monitor features approximately 150 percent higher luminance compared with the LUMIX S1R/S1, GH5 and GH5S for high visibility in outdoor use. Adopting a new mechanical structure, it achieves both tilt and rotation movement so that users can easily change angles without unplugging HDMI, USB or other cables. 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. It also incorporates a Night mode that provides mild backlighting and lets the user watch the subject comfortably, even immediately after viewing the monitor in a dark environment for a long time.
The LVF (Live View Finder) is the key factor for completing the ultra-high-speed response of the camera. The LUMIX S1H, as well as the S1R and S1boasts the world’s highest Real View Finder level of 5,760k-dot resolution. The 0.78x magnification ratio can be switched to 0.7x or 0.74x according to the shooting situation. Adoption of a high-speed, high-precision OLED for the LVF achieves a smooth display at 60 fps/120 fps (switchable) and high-speed response with minimum lag time of approximately 0.005 sec as well as 10,000:1 high contrast for exceptional visibility. With minimum distortion and high optical performance, the Real View Finder provides a natural view as seen with the naked eye. It is consistently sharp and clear from the centre to the corners.
High photo shooting performance as a digital camera
The LUMIX S1H captures both high-quality video and stunning still photos. It is capable of shooting images in 14-bit RAW format for precise reproduction of details.
Taking full advantage of its high-resolution sensor, the LUMIX S1H provides a High Resolution mode that faithfully captures even tiny details to be saved as beautiful, highly realistic RAW images. Eight consecutive images are automatically shot while shifting the sensor using the Body I.S. (Image Stabilizer) mechanism and synthesized into a 96-megapixel equivalent (12,000 x 8,000-pixel) image by the latest Venus Engine, which boasts high-speed signal processing. This mode is suitable for taking natural landscapes or fine arts with delicate details. This magnificently high-resolution photo is ideal for landscape photography of stationary subjects using a tripod. However, it can also be used in situations where moving subjects are included in the scene, by switching the sub mode.
Panasonic has achieved a high-speed AF with its advanced control technology over the major devices: lens, sensor and imaging engine. The lens and sensor communicate at a maximum 480 fps. Combining the Contrast AF with DFD technology, the LUMIX S1H realizes an ultra-high-speed, high-precision AF of approximately 0.08 sec. The LUMIX S1H also boasts high-speed burst shooting at 9 fps (AFS) or 6 fps (AFC). With its high subject tracking performance, it never loses the target subject. A camera that excels in low-light shooting, the LUMIX S1H boasts -6EV luminance detection performance with Low Light AF thanks to the higher sensitivity and optimized tuning of the sensor. The face/eye detection technology makes it possible to capture people in crisp focus. The Eye AF even detects the pupil of the eye and precisely focuses on it for impressive portrait shooting. The LUMIX S1H also incorporates Advanced AI Technology that detects specific subjects - humans and fast-moving animals, including cats, dogs and birds. The camera continues tracking its subjects even when they turn their back to the camera.
