The Lumix S1 is a well-rounded camera that forms part of Panasonic's entry into full-frame mirrorless and offers cutting-edge feature sets for both stills and video in addition to a durable physical design. The S1 is distinguished by its full-frame 24.2MP MOS sensor, which is backed by an upgraded Venus Engine. It also features a quick 9 fps shooting rate, an expanded sensitivity range up to ISO 204800, and impressive image quality. The S1's video capabilities include 4K60p for up to 29:59 and UHD 4K30p with full pixel readout, 4:2:2 10-bit colour, and unlimited shooting times. The dedicated Hybrid Log Gamma mode allows for HDR video recording, and a firmware update will be available to add 4:2:2 10-bit internal recording in addition to V-Log. The image sensor also makes use of a sophisticated DFD contrast-detection autofocus system for quick and accurate focusing and subject tracking, enhancing both stills and video capabilities. For sharper handheld shooting, sensor-shift image stabilisation also reduces the appearance of camera shake by 6.0 stops.
Beyond its imaging capabilities, the S1 stands out for its body design, which includes a 3.2" 2.1m-dot triaxial tilt touchscreen LCD and an impressively high resolution 5.76m-dot OLED electronic viewfinder. The magnesium alloy body has a top status LCD for quickly reviewing shooting settings and is weather-sealed to allow operation in inclement weather. Flexible storage options are provided by CFexpress Type B/XQD and SD card slots, and Bluetooth and Wi-Fi connectivity allow for wireless image transfer to tablets and smartphones in addition to remote camera control.
24.2MP Full-Frame MOS Sensor and Venus Engine
The S1's imaging capabilities have been optimised for high sensitivity, a wide dynamic range, and flexible recording modes thanks to a full-frame 24.2MP MOS sensor and an updated Venus Engine. Multipixel Luminance Generation and Intelligent Detail Processing technologies, which are incorporated into the sensor and processor, help to produce high resolution and definition by reducing colour moiré. Color Control further improves colour reproduction, particularly in the highlights and shadows. The processing power of the Venus Engine also contributes to reducing noise levels across the ISO 100–51200 sensitivity range and enabling quick full-resolution continuous shooting speeds of up to 9 fps with AF-S or 6 fps with AF-C, for more than 90 consecutive raw files.
UHD 4K HDR Video Recording
In addition to shooting still images, the S1 is a powerful video camera that can record in UHD 4K30p at full pixel readout, 4:2:2 10-bit colour, and for an unlimited amount of time, as well as UHD 4K60p at up to 29 minutes and 59 seconds. Up to 60p and unlimited recording times are also supported for full HD recording. Additionally, 2x and 6x slower motion are available in the high-speed recording modes for UHD 4K60, with 30 fps playback, and Full HD 180 fps, with 30 fps playback.
A High Dynamic Range (HDR) mode and a dedicated Hybrid Log Gamma (HLG) Photo Style mode can be used to expand highlight and shadow details and provide more flexibility when colour grading, enhancing the video quality. Internal recording with 10-bit colour depth and 4:2:2 sampling will be supported by an optional, paid firmware update, which will also support V-Log. Additionally, an external microphone and headphones are supported via dedicated 3.5mm jacks, and recording to an optional external recorder is possible via the HDMI Type A port.

Sensor-Shift Image Stabilization
In order to compensate for a wider variety of movement types and produce sharper, clearer imagery, Dual I.S. 2 combines the S1's 6.0 stop-rated 5-axis sensor-shift image stabilisation technology with lens-based 2-axis image stabilisation. O.I.S.-compatible Lumix lenses must be used with Dual I.S. 2. A camera shake of about 6.5 stops can be compensated for by this stabilisation system.
DFD Autofocus System
With sensor and lens communication rates up to 480 fps, DFD (Depth-From-Defocus) technology enables accelerated autofocus performance by quickly calculating the distance to subjects and adjusting the focusing position in as little as 0.08 seconds. Subject type, colour, size, and motion vectors are used to intelligently lock-on to the moving subjects and ensure precise focus in this contrast-detection type focus method, which benefits both still and video recording modes as well as subject tracking applications. Face/eye detection capabilities make it simpler to photograph people when working with portrait subjects and prioritise focusing as precisely as on a subject's pupil. While AF Far Shift favours subjects in the distance, AF Near Shift favours subjects that are close to the camera. It is possible to modify the focusing sensitivity and speed to further enhance performance with particular subjects. Additionally, it has 225 AF zones, which offer superb control over the camera's focusing. A Low Light AF feature also supports working in low-light situations and allows accurate AF performance down to -6 EV.
Focus peaking, which highlights sharp contrast edges with a coloured outline to help you quickly identify your focus point, and Touch MF Assist, which enables touch-to-focus operation, are features that benefit manual focus operation. A custom selectable AF zone for Multi AF / Custom Multi AF and an AF Point Scope setting that temporarily magnifies the subject by 3x to 10x for focus position confirmation are additional AF features.
6K and 4K PHOTO
Utilizing the S1's video recording capabilities, a trio of still shooting modes are available for recording continuous 3:2 or 4:3 8MP stills at a 60 or 30 fps shooting rate or 18MP stills at a 30 fps shooting rate:
- Burst: This mode will allow you to continuously record, making it ideal for instances where you need a fast frame rate in order to capture the best moment.
- Pre-Burst: This mode is ideal for times when you're unsure of the critical moment to press the shutter button and will record images one second prior to and one second after pressing the shutter button in order to give you 60 frames to choose from.
- Burst (S/S): This mode most closely follows the video recording process, and allows you to playback your video, pause at the chosen moment, and use the shutter button to mark a chosen frame from the video and save it as a single 8 or 18MP frame.
Bluetooth and Wi-Fi
With very little power consumption, Bluetooth Low Energy (4.2) maintains a connection between your smartphone or tablet and the camera. IEEE 802.11ac and b/g/n support is also available for more robust wireless activities for faster transmission, fluid remote control, and monitoring.
Lumix Sync, an iOS and Android app that pairs with the camera to enable remote shooting control and wireless image transfer using a smartphone or tablet, completes the camera's wireless connectivity. Wi-Fi can be used to send 4K video files to a smartphone.
Other Camera Features
- By using sensor-shift stabilization technology, the S1 features a High Resolution mode to capture and compile eight separate exposure to create a single 96MP raw or JPEG file. Suitable for static subjects and when working on a tripod, this mode creates a more highly detailed and color accurate image than a single shot alone can produce and produces an image with a 12000 x 8000-pixel resolution.
