Panasonic Lumix S1H Review

Pinterest LinkedIn Tumblr

The Panasonic Lumix S1H could easily look like a ‘video’ version of its 24-megapixel Lumix S1 mirrorless camera, and in the past, it has been pretty difficult sometimes to unravel the different video credentials of Panasonic’s Lumix G cameras. This time, though, the difference is clear – the Lumix S1 is a stills camera that’s pretty good at the video; the S1H is most definitely a video camera that also happens to be pretty useful for stills.

Its video specifications are impressive enough, but with plenty of rivals snapping at its heels, it also relies on other key cinematography features to make its mark – many of them alien to stills photographers, but essential to professional filmmakers.

Key Features

Panasonic aims to deliver cinema-quality video with the Lumix S1H, and it has the features to back that up.

The headline spec is its ability to capture 6K video (yes, 6K), either in a 3:2 ratio at 24p and 10-bit 4:2:0 quality, or 5.9K in a conventional 1:9 ratio at 30p/25p/24p. At this level, though, processing power is the limiting factor, so with 6K or 5.9K capture, you’re restricted to the cropped Super 35mm format.

Bit-depth is important. 8-bit capture is OK for video footage that’s not going to be heavily edited or ‘graded’ later, but if you’re likely to apply heavy adjustments and especially if you’re going to use V-Log modes, you really need the extra bit-depth of 10-bit capture to avoid banding, clipping and other artefacts.

The intention with the 6K capture is not necessarily to produce 6K movies but to offer extra cropping wiggle-room during editing for 4K output.

The S1H does offer full-frame (uncropped) capture for 4K, with 4:2:2 10-bit internal recording and speeds up to 60p. You can use 60fps catch and playback for fast action, or 30fps playback for a 2x slow-motion effect.

The 4:2:2 figure refers to the way colours are compressed. 4:2:0 compression is the standard method for internal recording with most cameras, but 4:2:2 is less compressed and offers better high quality – it’s also relatively uncommon for inner recording.

Processing all this video data needs powerful processing hardware, which also throws out a lot of heat. Many video cameras have continuous filming time limits, either to avoid extra taxes on ‘video’ cameras or just because they get too hot.

The S1H has no such limitation. You can film for as long as you like, and heat is dissipated by a silent internal fan – the first use of a fan in a mirrorless camera, though they are found on broadcast and cinema cameras. This is one reason why the S1H is a lot thicker than the regular S1.

Other features include built-in V-Log/V-Gamut modes with 14 stops of dynamic range. It’s pretty hard to judge footage shot with V-Log mode in-camera as it looks flat and unsaturated, but you can download and install Panasonic’s VariCam LUT library to preview the final footage via the camera’s LUT View Assist mode.

Finally, the Lumix S1H offers Dual Native ISO, where it switches between two noise control circuits depending on the ISO setting. It has a base ISO 640 Low ISO circuit for the lower end of the ISO variety, and a base ISO 4000 High ISO/low noise circuit for better image quality at high ISO settings.

Build and Handling

The difference in size between the Lumix S1H and the regular S1 is immediately obvious. The S1H has a much thicker body, which leaves room on the top plate for a larger status panel. This has changed from the standard black-on-green LCD display of the S1 and S1R to a white-on-black (or blue, with the backlight activated) screen with larger characters.

Round the back, there’s a robust-feeling vari-angle display rather than a tilting screen, which can flip out sideways and forwards. It has an unusual feature – it’s mounted on a ‘tray’ which can be pulled out from the back again of the camera so that the screen clears the cable sockets on the side of the digital camera. This is a neat feature that could prove essential when the S1H is installed on a rig and wired up to external recorders, monitors and mics.

The air vents for the cooling system are at the side, between the screen and the camera body. Apart from making sure they’re not covered, you can forget about these as you don’t really notice them when you’re filming and shooting.

Perhaps the biggest difference from the regular S1 and S1R, however, is the video interface. This is designed for videographers not really stills photographers, so shutter speeds are swapped for ‘shutter angles’ and there’s an ‘iris’ setting, not an aperture setting.

Compared to its rivals in the mirrorless camera market, the S1H feels big, heavy and a perhaps a little unwieldy at around 1.6kb – but this is no run-and-gun vlogging camera – it’s going to be used in a rig or on a tripod and is designed for a kind of film where the cameras are normally much larger and heavier than this.

Perhaps it’s worth it. Design-wise there are some nice flourishes for vloggers as well as filmmakers. For example, there’s a big red record button on the front and also tally lights on both sides to let both the operator and the presenter know that the S1H is recording. That’s a great idea, but the most obvious is the bigger 1.8-inch status display on its shoulder, which is twice the size of its sister cameras and holds a lot more information. It’s also got a slightly bigger grip than the S1 and S1R.

For stills photography, the Lumix S1H feels and behaves very much like the regular Lumix S1, though with a bit more weight and bulk. Panasonic has stuck with its contrast-based DFD AF system, but while this works well enough in single-shot mode, it’s less convincing in C-AF mode, especially in lower light levels. It’s surprising that Panasonic has swapped to dual SD/SDHC/SDXC UHS-II card slots in a camera designed for high-end video and cinematography. We were told that even for 6K capture it didn’t really warrant the newer and faster CFexpress card support in the S1 and S1R and that this was only necessary for these cameras’ high-speed RAW catch (the S1R in particular, we presume). Panasonic says UHS-II SD cards are fast enough and that videographers will want identical card slot machines as they frequently use matched memory cards for shooting.


As you would expect, the Lumix S1H produces great quality video, though it is a high-end tool aimed at video experts and there are A LOT of frame rate and resolution options that could get confusing if you don’t keep your wits about you.

We also like the ability to customise the screen display to suit your cinematography style, for example with a widescreen crop and opaque surround.

The in-body image stabilization is great to have, and there’s a big, chunky battery too – though, with a modest life of 400 images (rear monitor) or 380 images (LVF), it’s not quite up with the latest Sony Alpha models for endurance.

The S1H body and the 24-105mm f/4 lens we used for our tests feel super-solid, but this camera-lens combination is very, very heavy for handheld videography. It wouldn’t balance on our DJI Ronin SC gimbal so you’d probably need the Ronin S or a heavier-duty two-handled rig.

The continuous autofocus gave us some trouble too, as you can see from our sample video footage above. It’s possible we didn’t find the optimum setup – there are a lot of options and then sensitivity choices within those options again – but this and the camera’s weight count against it for a run and gun design shooting. It’s best to think of the Lumix S1H as a portable, affordable cine camera – if it’s a vlogging tool you want, you’d be better off with a Lumix GH5 or G90/95.

With the Lumix S1H, Panasonic has used its considerable video experience to bring many of its high-end VariCam features to the Lumix S range. The controls, the interface and certainly the hardware have been build for video and cinematography, and the fact it’s also a very serviceable 24MP stills camera is a bonus. But with the cheaper and smaller Fujifilm X-T3 furthermore able to shoot 4K 60p 10-bit 4:2:0 (internal) and 4:2:2 (external) video and Blackmagic building raw video capture into its cameras, the S1H is only one of several options for higher-end video makers, and its size and weight do count against it for handheld video and vlogging.
