Review: Panasonic Lumix GH6

In-body stabilization and thoughtfully designed controls make this workhorse a great choice for in-the-field photographers and filmmakers.

S-tier image stabilization. Satisfyingly tactile controls. Apple ProRes video recording. Handy focus/balance features. Charges via USB-C (and operates with 9V USB-C).

Contrast-detect autofocus is good but not ideal. Middling battery life. Recording to SSD is not available yet.

Panasonic’s high-end mirrorless cameras have been the go-to for independent and documentary filmmaking for years. In 2017, Panasonic introduced the original GH5, the flagship model that took three years to build. It was speedy, rugged, and easy to use—a massively popular, clear standout in the market.

A lot has changed since then. Other manufacturers are now building great cameras for filmmakers that can shoot 6K footage. But the new GH6 continues to hold its own for videography and photography alike, especially at this price point. 

Control Panel

There's a surprising amount of heft to the GH6 but not so much that it becomes a wrist strain. It comes with a UHS-II SD card slot as well as a CFexpress card slot, which becomes necessary for higher-end video shooting (more on that below). Its three-inch flip-out screen can be rotated so it's visible to the subject of the camera, making it handy for online content creators who have to be their own production team.

For run-and-gun photographers and filmmakers, the body is built for functional muscle memory. Alongside typical layouts like the white balance, ISO, and exposure compensation buttons along the top, or dials to control things like aperture without taking your hand off the body, there are also multiple red buttons for recording video. There's one button on the top plate and another on the front. You can start recording footage, no matter which photo mode you're currently in.

The material on this camera has some of the most satisfying tactile feedback I've encountered on a camera. Its design isn't that far off from many other cameras like it, but the distinction is in the subtleties. For example, the audio information button along the top is rubberized, which gives it slightly more friction than the machined metal video button right next to it. Once you're familiar with the layout, little details like this make it easy to tell exactly which button or dial your finger is on without looking.

The kit comes with a slightly better-than-standard f/2.8, 12–60mm variable focal length lens. It also includes optional Power OIS, which, combined with the in-body image stabilization, makes the whole system impressively smooth, even when freehanding shots. Inside, the GH6 packs a 25.2-MP Micro Four Thirds sensor. It's a little on the small side, but it works well enough for this camera.

Battery life, unfortunately, is middling. A fully charged battery will last about an hour of continuous usage, whether that's photos or 4K video. However, that could be substantially less, especially if you rely on Apple ProRes recording. Conveniently, however, you can charge the battery using the device's USB-C port. If it can supply enough power (around 9 V/3A), then you can operate the camera off USB-C power. Still, you might want a spare battery or two.

Balance and Focus

The Lumix GH6 feels like it expects you to use it while on the go. The level gauge overlay display has a built-in accelerometer to display lean and tilt, turning green when you're as level as can be. This is the kind of feature that is unnecessary if you have a good tripod or gimbal, but if all you can bring with you is your camera and your feet, it's a handy tool.

The camera uses contrast-detection autofocus. This type of autofocus is increasingly outdated, but at least the GH6 does well with it. A blue overlay will highlight the areas of the image that are in sharp focus, and repeatedly pressing the autofocus button can (sometimes) switch between different subjects in focus. 

When rotating the focus lens manually, a gauge pops up indicating the focal distance and, crucially, which direction you're moving the focus. This is the kind of extremely handy feature that's hard to do without once you have it—no more guessing whether you've over- or under-shot the focus.

Options Upon Options

The GH6 came with an already impressive range of video recording options, and a firmware update in late July added even more. The star of the show is the addition of Apple ProRes 422 and 422 HQ. Depending on your storage media, you can shoot up to 5.7K video at 30 fps in ProRes 422 HQ, one of the best compressed codecs you can use without diving into studio-level cameras. This is particularly handy for filmmakers looking to edit for 4K output.

Storage media matters because, for certain video settings, the SD card you have laying around probably won't cut it. Most typical SD cards max out at around 300MB/s read speeds, but their write speeds can often be much lower. For example, this 128-GB SD card tops out at around 120 MB/s when writing and is usually on sale for about $36. Meanwhile, a 128-GB SD card that can record at the nearly 240 MB/s required for 5.7K ProRes footage costs around $120, at the time of writing.

Fortunately, after the update, there are options to still use ProRes 422 and 422 HQ at resolutions as low as 1080p (which wasn't possible before the firmware update), and at frame rates up to 60 fps, as well as a few other less bandwidth-heavy formats. Overall, you'll have plenty of options to record with. The aforementioned CFexpress slot also gives you more recording options.

Panasonic has announced that USB-C-to-SSD direct recording will be available in the future, also through a firmware update. We prefer not to base our opinions on features we haven't tested yet. But if recording to an SSD is important to you (and it should be for recording really large videos, because an SSD is one of the best ways to do so), it might be worth waiting to see when that feature is added. The ProRes update dropped while I was writing this review, so Panasonic has delivered on some of its promises already.

That said, this is a tiny bit of a bummer. Cameras like the Blackmagic 6K are slightly cheaper and support SSD recording out of the box, and they offer the choice of both ProRes and BRAW formats. The GH6 may be on par with cameras like this eventually, but it's a lot of money to spend on something while you wait for all the features to show up.

While I'm nitpicking; the GH6 also forces the user to choose a combination of recording format, frame rate, and bitrate from a giant list, buried in a menu. This isn't uncommon for mirrorless cameras, but—once again—the Blackmagic camera allows you to set each independently and more accessibly. None of these issues are crucial enough to disqualify the camera from video work, but it is less convenient. 

But most notably, the GH6’s in-body stabilization is nothing short of incredible. Panasonic claims you can get up to 7.5 stops of stabilization, which means that you can make your shutter speed up to 7.5 stops slower before noticing the same level of shaky blur in your video. In practice, it made freehanding shots without a gimbal possible.

While it's still advisable to use a tripod or gimbal when you can, it's not always feasible on run-and-gun shoots. For filmmakers who find themselves trying to get smooth motion while traveling light, the stabilization on this camera is a godsend. 

Overall, it's hard to find a camera that's more forgiving if you don't break out the tripod or that's easier to snap shots without futzing around with fiddly controls. It also makes for an excellent video camera, though you might want to wait for SSD recording or invest in a heavy-duty SD/CFexpress card. If having a lightweight rig that still gets smooth shots out in the field is more of a priority for you than tweaking your shutter speed on the fly, it's hard to do better than this.
