Video quality settings via the Quick Menu

The GX85 is capable of 4K video capture at 30p and 24p. Video is captured as an MP4 at up to 100Mbps. It is also capable of 1080p capture at 60 fps, 30 fps and 24 fps (the latter in AVCHD only) at 86Mbps.

Video tools include focus peaking, microphone level adjustments (with a wind filter option) and zebra patterns for monitoring highlights. Users can shoot video in PASM modes and can also use creative filters during video capture. As with the GX8, you can not use Auto ISO in manual mode during video capture, while also using exposure compensation to adjust brightness, which is disappointing.

Thanks to the GX85's excellent touch interface, racking focus during video capture couldn't be easier. Also cool, the GX85 features the 4K Live Cropping feature first introduced on the Panasonic ZS100. This feature lets you specify a start and endpoint to produce a 1080p clip that appears to either pan or zoom, but does so using the 'extra' pixels captured in 4K. You can see an example of it above.

Of course, one of the biggest appeals of the GX85 is its 5-axis image stabilization with Dual I.S. during video capture. We've compared its IS video capabilities to other cameras on the previous page. But for a real world example, take a look at the clips below:

ISO 200, F22 at 1/100 sec. Shot in 4K/24p at a 24mm equivalent, handheld.

Exposure: ISO 6400, F3.8 at 1/25 sec. Shot in 4K/24p at a 30mm equivalent, handheld using the Panasonic Lumix G X Vario 12-35mm F2.8.  

Both of the above clips were shot in 4K mode at 24p, handheld. In addition to showing what the GX85 is capable on the video front, both should also give you a good idea of how helpful Dual I.S. can be during capture. Overall, 4K video quality looks good in both low and bright light.

Our video still confirms initial impressions from looking at sample footage out of the GX85: 4K video quality is impressive, with excellent detail, nearly on par with the GX8. Despite the lack of an AA filter, the GX85 displays minimal false color.

1080p video quality appears significantly less sharp than that of the GX8. Compared with other 16MP Four Thirds cameras, like the Olympus E-M5 II, 1080p quality also appears less detailed.

While the GX85 has a lot to offer from a video perspective in terms of quality, for serious video shooters, it worth keeping in mind that there is no 'CinelikeD' color profile like that offered in the GH4, and no microphone or headphone sockets. However there is a clean HDMI out option for capturing 4K video to an external recorder. 

Features

L.Monochrome JPEG Profile

Moody black & white JPEG profiles are all the rage these days and Panasonic wants in on the fun. Meet the new L.Monochrome mode, which according to Panasonic, is meant embody the 'deep black and rich gradation like that of B/W film.'

Auto ISO

There are two ISO modes available on the GX85: Auto and Intelligent. Auto ISO is a very simple implementation: it doesn't let you specify a shutter speed (or relationship to focal length) at which the camera will increase the ISO setting, but it does let you choose an upper ISO limit. Intelligent ISO is a little more clever: it doesn't allow any user input beyond setting the upper limit, instead trying to detect movement in the scene and increasing the ISO to ensure a suitable shutter speed is used.

Auto ISO is available in manual exposure mode, but the camera won't let you use exposure comp to specify how bright the image should be. Auto ISO is only available for video when shooting in P, A or S modes (so there's no way of setting your shutter speed and aperture, then getting the camera to maintain brightness).

Bracketing

GX85 users can bracket exposure, aperture, focus and white balance ( the last when shooting JPEG only).

Bracketing exposure or white balance can prove exceptionally handy. With the GX85, users can also bracket aperture and focus. When bracketing aperture, users can elect to bracket 3, 5 or all available apertures. When bracketing focus, users select the number of focus 'steps' between shots, as well as the number of shots, which can range from 2 to 999.

Wi-Fi

The GX85 offers the same, very functional Wi-Fi implementation as the GX8. Once paired with the Panasonic Image app, users can view and download images, view videos, and control the vast majority of the camera's core functions for remote shooting.

In use, I found the Panasonic Image app very easy to use, in general, and quite robust. I installed it on an iOS device and paired it with the GX85 with ease.

Other Features

Like its big brother, the GX85 is packed with a lot of cool and useful features, many of which make use of its 4K video capture capabilities. 4K Photo mode is one of them, and it works by capturing a short 4K clip (in the 4:3 aspect ratio) and allowing users to extract ~8MP stills. This mode is cool because it gives photographers the ability to capture very specific moments in time, at the equivalent of an insanely high frame-rate. It's also very easy to use. 

Another cool feature which we also saw on the GX8, is post focus. It works by racking focus while capturing 4K video, allowing the users to generate a JPEG from the clip using a cleverly designed interface. Below is an example of it taken from the GX8 review (the GX85 is functionally identical).
