Panasonic Lumix DMC-GX8 Mirrorless MFT (Micro Four Thirds) Camera Body, Black {20.3MP}

Panasonic GX8: 20MP Micro Four Thirds flagship with Dual IS and 4K

The GX8 marked a turning point for Micro Four Thirds resolution, pushing past the 16MP ceiling that defined the system for years to land at 20MP on a stabilized Live MOS sensor. That sensor sits inside a weather-sealed magnesium alloy body with a rangefinder profile, giving you a camera that can handle drizzle without a second thought. The fully articulated 3-inch OLED touchscreen and tilting 2,360,000-dot EVF with 0.77x equivalent magnification round out a physical package built for photographers who spend serious time composing.

The Dual IS system combines four-axis in-body stabilization with the optical IS in compatible Panasonic lenses, delivering measurably better results than either system working alone. For video, the GX8 shoots UHD 4K at 30p and 24p with a 100 Mbps bit rate, and the touchscreen pull-focus during recording is genuinely useful in practice. Burst shooting tops out at 10 fps with the electronic shutter, or 8 fps mechanical, and the electronic shutter also opens up a 1/16000 sec maximum speed for shooting wide open in bright light without filters. AF works down to -4EV, making this camera usable well into low-light territory where contrast-detect systems typically start hunting. At 330 shots per charge, battery life asks for a spare in the bag on long days, but the rest of the spec sheet has aged with real staying power.

Who It's For

Travel photographers who shoot in variable weather will appreciate the sealed body paired with Dual IS, which cuts camera shake significantly when paired with a compatible Panasonic lens. Documentary and street shooters benefit from the tilting EVF, silent 1/16000 sec electronic shutter, and touchpad AF that lets you shift focus points without pulling the camera from your eye. Videographers working in run-and-gun situations get 4K at 100 Mbps with in-camera flat profiles and touch-to-pull-focus. Landscape photographers running timelapse sequences can generate 4K video directly in-camera and shoot to 30-minute bulb exposures.

FAQ

How does Dual IS actually perform compared to using a stabilized lens alone?

In testing, Dual IS delivers roughly one stop more stabilization than optical IS by itself-measurably better, but not a game-changer. It works best with compatible Panasonic lenses that have firmware updates; older Mega OIS lenses don't support it. For video, the body-based stabilization is unavailable in 4K, so you'll still need an optically stabilized lens for stabilized 4K footage.

Can you shoot wide open in sunlight without an ND filter?

Yes. The electronic shutter maxes out at 1/16,000 sec, giving you an extra stop over the mechanical shutter's 1/8,000 sec. That's enough to shoot at f/1.4 in bright daylight at ISO 200 without a filter. The trade-off: electronic shutter can introduce rolling shutter artifacts with fast-moving subjects or panning.

How low-light is the autofocus really?

It locks focus down to -4EV with a sufficiently bright lens, which is genuinely dim-well beyond where most contrast-detect systems start hunting. Single AF is quick and confident in those conditions, making this camera very usable for night cityscapes or events. Continuous AF will still hunt more than hybrid systems, especially with fast-moving subjects.

What's the practical battery life on a long shoot?

330 shots per charge is on the lean side. You'll want a spare battery in your bag for all-day work. No surprises there-it's a known limitation of this generation of mirrorless cameras.

Does the 4K video really hold up without in-body stabilization?

4K is captured at 100 Mbps without sensor-shift IS, so you need an optically stabilized lens for smooth handheld 4K. The 1080p modes do have electronic stabilization available. The camera also crops tighter for 4K than 1080p-roughly 1.25x field reduction compared to stills.

Can you extract stills from 4K video in-camera?

Yes. The 4K Photo mode lets you record video and pull 8MP still frames from any moment in-camera. It's genuinely useful for fast action or when you can't decide between stills and video, though the extracted images are JPEG-only-no RAW extraction.

What's missing compared to the GH4?

The GX8 is positioned below the GH4. It lacks Cinema 4K, a headphone jack, 200 Mbps bitrate, and 4:2:2 10-bit uncompressed HDMI output. The GH4 is built for serious video work; the GX8 is a still-focused flagship with solid 4K as a secondary feature.
