It is a curious question @bannedindv, because the BGH1 had no IBIS, but neither did the GH5S that was based on.

Yet this is the box format camera of the S1H, which of course does have IBIS!

If Panasonic does have IBIS, it will be the first modular "box format" cinema camera with IBIS.

But I wish it had internal NDs instead! So much more important, and there is no meant of it?

Next generation Z Cam E3 might be a better option then. (if/when it happens? Assuming they take the next half step forward, and offer their eND with a 0ND option)

Atomos just leaked the camera basically. From an email blast :

Meet The Newest Iconic Duo

With the Atomos Ninja V/V+ HDR monitor-recorder, the Panasonic LUMIX BS1H will be ready to bring Apple ProRes RAW support to the next level –capable of recording up to 5.9Kp30, 4.1Kp60 and 3.5Kp50 anamorphic ProRes RAW.

This combination for multi-camera productions is facilitated by the cameras’ LTC and Genlock inputs to perfectly complement Atomo’s UltraSync One wireless sync system*. Together, they work fantastically alongside the AtomX SYNC module for both Ninja V and V+.

so what was the AF situation in S1H? Or is this high end cinema and we can pretend not to care. Unlikely to ever consider this, it fills no role for me. Expensive lenses one has to buy because there's no rentals. Still dinky looking package to the casual observer, unless rigged to unnatural proportions. Often, that casual observer is the client, who still judges your ability on package size. This could live at the intersection of relative stealth and shallow DOF, but it's an empty Venn diagram for me. I totally get the technology packaged as a photo camera, with photo shooting as the primary use case.

Confirmed, no IBIS. I like that aspect personally.

So no IBIS, no ND, no stills, and no screen? But the same price as an S1H? What's supposed to be the advantage here?

@DrDave S6 is a different beast to the BS1H, as that is a totally different sensor, a better comparison would be with the Z Cam E2-F6 which shares the same sensor as is inside the Panasonic BS1H. But Z Cam costs $500 more.

But yes, I do think S35 is a better sweet spot, have been tempted by the Z Cam E2-S6 after the price cut. (but now there is out the P6K Pro competition)

What MFT lenses don't work with the E2-S6? Have you tried using DZOFilm, Meike, SLR Magc, or Vazen MFT lenses on the S6?

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.

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.

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.

• Full-frame - 5.9K (5888x3312) 29.97p/25p/23.98p 16:9 12-bit
• Super 35mm - 4K (4128x2176) 59.94p/50p/29.97p/25p/23.98p 17:9 12-bit
• Super 35mm Anamorphic - 3.5K (3536x2656) 50p/29.97p/25p/23.98p 4:3 12-bit

• Please refer to the Atomos website for the information on the corresponding firmware version of Atomos Ninja V.
• Software that supports Apple ProRes RAW is required to edit RAW video recorded with NINJA V. Apply the LUT (Look up table) available on the following customer supports site to make the same color grading as V-Log/V-Gamut
• https://panasonic.jp/support/global/cs/dsc/download/lut/s1h_raw_lut/
• All functions may not be available depending on the situation.

Blackmagic RAW

• Selectable recording mode depends on the firmware version of Blackmagic Video Assist 12G HDR.
• Please refer to the Blackmagic Design website for the information on the corresponding firmware version of Blackmagic Video Assist 12G HDR.
• DaVinci Resolve or DaVinci Resolve Studio is required to play back and edit Blackmagic RAW data. DaVinci Resolve Studio is required to deliver projects using Blackmagic RAW data in resolutions over 3840x2160.
• All functions may not be available depending on the situation.

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.

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.

answering myself after the tiniest bit of research: It does! I've been under a rock the past year. What I do find confusing is the Video Assist lists only the SDI port as capable of RAW acquisition (SDI RAW), whereas many of the cameras below are photo cameras, with no chance in hell of having an SDI port. Logically, the Video Assist has to acquire RAW over HDMI, too. " Blackmagic Video Assist 7” 12G HDR Blackmagic RAW Supported Cameras
