Panasonic Lumix DC-BS1H brings S1H full-frame performance to box-format camera

0

The Panasonic BS1H is a compact box-shaped modular video camera built around the same components as the S1H full-frame mirrorless camera. As such it offers open-gate 6K capture, 5.9K 16:9 capture, anamorphic support, and Raw output to Atomos or Blackmagic recorders.

Like the existing Micro Four Thirds BGH1 model, the camera has no screens and relies on the use of HDMI, SDI, Ethernet or Wi-Fi communication for monitoring. It has a series of customizable buttons on the body and all its menus can be controlled from a computer or smartphone-based app.

The whole design of the camera is based on the idea of maximizing flexibility by creating a pared-back camera unit with extensive connection options and protocols, allowing its use in a variety of situations where a camera-shaped model isn’t well suited.

Key specifications

  • 6K ‘open gate’ 3:2 shooting at up to 24p in 10-bit
  • 5.9K 16:9 capture (10-bit or 12-bit Raw output) up to 30p
  • UHD or DCI 4K from 5.9K, up to 10-bit 30p
  • UHD or DCI 4K from Super35 crop at up to 60p
  • Full-size HDMI, SDI, Ethernet and USB 3.1 (USB 3.2 Gen 2)
  • Timecode and Genlock
  • Built-in fan for unlimited recording

It has a built-in fan, allowing unlimited recording in all modes, and accepts Panasonic’s large pro-video ‘V’ type batteries, when it’s not being directly powered over USB or Power-over-Ethernet. The camera can be operated remotely as part of a fixed camera setup at a venue (mounted in the ceiling of an auditorium, for instance), or on a gimbal, where its lower weight make it easier to stabilize.

The most significant difference between the S1H and the BS1H, beyond the lack of screens and viewfinder, is an absence of internal stabilization mechanism. There is the option to use Boost IS mode when the camera is used with one of Panasonic’s stabilized lenses, maximizing the effect of the lens’ IS for more tripod-like static shots.

The dimensions of the BS1H are virtually identical to those of the Micro Four Thirds BGH1 model, with the only significant difference being an 0.8mm (~1/32″) increase in depth to accommodate the deeper flange-back distance of the L mount. The company says the majority of cages designed for the BGH1 will fit the new camera perfectly. The BS1H is also designed so it can work as part of a multi-camera setup alongside BGH1s running on the same network.

The BS1H offers a wide variety of capture and output modes, including 10-bit output of up to 1080p over its SDI connector, gamma-encoded 4K or 5.9K Raw over HDMI, while also capturing footage to its internal twin SD card slots. It also includes both Timecode and Genlock inputs for precise synchronization of cameras.

The BS1H will be available from November at a recommended selling price of $3500.

Panasonic Announces the LUMIX BS1H Full-Frame Box-Style Mirrorless Live and Cinema Camera Featuring A Compact Body with 6K 24p / 5.9K 30p 10-bit Unlimited Video Recording Capability

Newark, NJ (October 7, 2021) – Panasonic is proud to announce the release of the new full-frame box-style LUMIX Digital Single Lens Mirrorless Camera, the DC-BS1H. As its name suggests, the LUMIX BS1H is a versatile box-style camera that combines the cinema-quality video performance of the LUMIX S1H with an easy-to-deploy box-style profile. The LUMIX BS1H accommodates a 24-megapixel full-frame sensor with Dual Native ISO technology and includes features such as 6K full-area high resolution recording, impressive bokeh, excellent low-light performance, wide dynamic range of 14+ stops, V-Log and more.

The high connectivity and mobility of the BS1H enable users to flexibly use the camera to create their ideal camera system according to the scenario. In addition, consistency among their images minimizes post-production processing when used alongside other Panasonic LUMIX production cameras such as the BGH1 or the S1H.

1. Cinema production quality video with 35mm full-frame sensor

The BS1H 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 BS1H delivers approximately 24.2 million photosites. Adoption of an OLPF (Optical Low Pass Filter) suppresses moire and false color. The image sensor with Dual Native ISO in the BS1H minimizes noise generation by choosing an optimal circuit to use according to the sensitivity before gain processing. In combination with optimum signal processing by the Venus Engine, it assures maximum ISO 51200 high sensitivity recording with minimum noise.

Maximizing the use of the pixels in the full-frame image sensor, the LUMIX BS1H is capable of 6K/24p, 5.4K/30p (3:2 aspect ratio) or 5.9K/30p (16:9 aspect ratio) high-resolution, smooth video recording. It also provides 10-bit 60p 4K/C4K*1 HEVC video recording when using the image area equivalent to Super 35mm. The 4:2:2 10-bit 4K30p is recordable 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.

The LUMIX BS1H imports the renowned colorimetry of the VariCam lineup of Panasonic cinema cameras, enabling filmmakers to capture accurate colors and rich skin tones. The LUMIX BS1H delivers 14+ stops of Dynamic Range with a V-Log to precisely reproduce everything from dark to bright areas. V-Log/V-Gamut delivers a high dynamic range and broad colors and creates a greater level of play for the images in post-production processes. The LUMIX BS1H’s CMOS sensor achieves a wide color gamut known as V-Gamut, which is the camera’s optimum color space and achieves a color space that is wider than BT.2020. V-Log has log curve characteristics reminiscent of negative film and V-Gamut delivers a color space even larger than film.

In addition to HDR (High Dynamic Range) video recording, 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 BS1H also provides real-time subject detection with an advanced deep learning technology to set precise focus on the target subjects such as humans and animals even moving at fast speeds.

2. A wide variety of recording formats, frame rates and resolutions in maximum 6K

The LUMIX BS1H is capable of 4:2:2 10-bit 4K 60p/50p HDMI output. Designed to satisfy wide-ranging creative needs, the LUMIX BS1H adopts a new heat dispersion structure which achieves unlimited video recording in a variety of recording formats, including 4:3 Anamorphic mode, and provides two alternatives for RAW workflow. [5.9K] / [4K] / [Anamorphic (4:3) 3.5K] 12-bit RAW video data can be output over HDMI to save Apple ProRes RAW on the Atomos Ninja V or save Blackmagic RAW on the Blackmagic Video Assist 12G HDR.

The VFR (Variable Frame Rate) lets users record over cranked / under cranked 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 is recordable even when using auto focus. Further, a variety of effects are available for producing a slow-motion video through the postproduction process.

To support a growing need for live streaming, the BS1H provides an IP streaming function that enables distant, high-quality image transmission to the social streaming platform online with PC connection over wired LAN. Notably, the LUMIX BS1H can stream 4K 60p (50p) video in H.265. The H.265 realizes half the bitrate while keeping the image quality the same as H.264, which means it can provide 2x higher image quality at the same bitrate as H.264. Streaming in ultra-high definition 4K at low bitrate is possible even in the cases where the bandwidth is not broad enough.

3. A wide range of connections for unlimited possibilities

Composed of aluminum and magnesium alloy, the LUMIX BS1H body frame enables a compact and lightweight, yet durable, box-style camera, and provides a variety of practical ports. In addition to a USB 3.1 Type-C, a 3G-SDI (BNC) and an HDMI Type-A terminal are equipped, which can be used for simultaneous output. Moreover, Genlock IN (BNC) and Timecode IN/OUT (BNC) functions which enable multi-angle synchronized video recording are available to build a scalable system with manufacturer-agnostic external monitors, rigs and gimbals. When connected to LAN, Power over Ethernet+ (PoE+) makes it is easy to install both physically and electrically. Control over maximum 12 sets of LUMIX BS1H cameras*2 is available using Panasonic PC software LUMIX Tether for Multicam. The LUMIX BS1H is also equipped with a double SD Card slot for backup recording or relay recording.

Use of LUMIX S Series lenses with BS1H provides further advantages. The Boost I.S.(Video) function (Image Stabilizer) can be used and superior AF/AE control is available when the LUMIX S Series lens with O.I.S. (Optical Image Stabilizer) is mounted.
