Panasonic Lumix DMC-GX85 Mirrorless Micro Four Thirds Digital Camera Body

The Panasonic Lumix DMC-GX85 Mirrorless Micro Four Thirds Digital Camera Body (also sold as the GX80 or GX7 Mark II in other markets) is a rangefinder-style mirrorless camera, a smaller, lighter alternative to Panasonic’s GX8, aimed at photographers who want strong image quality, 4K video, and versatile shooting capability in a compact body.

At the core of the GX85 is a 16MP Four Thirds Live MOS sensor (17.3 x 13mm) built without an optical low-pass (anti-aliasing) filter, the first Panasonic Micro Four Thirds camera to go without one, paired with Panasonic’s Venus Engine processor, offering a native ISO range of 100-25600. Panasonic claims this filterless design delivers approximately 10% more fine-detail resolving power compared to cameras with a similar sensor that retain a low-pass filter. Autofocus uses a 49-point contrast-detection (Depth From Defocus) system with multi-area, center, selective single-point, tracking, touch, and face-detection modes. Continuous shooting reaches up to 10fps with single-shot autofocus (AF-S), 6fps with continuous autofocus (AF-C), or up to 40fps using the electronic shutter.

A standout feature is 5-axis sensor-shift image stabilization, working together with Panasonic’s Dual I.S. system when paired with a compatible stabilized lens for enhanced combined correction. Video capability includes UHD 4K recording at 30p and 24p (100Mbps bit rate), along with Full HD 1080p, and 4K Photo modes that let photographers extract 8MP stills from 4K footage at up to 30fps. The electromagnetically driven shutter offers mechanical speeds from 60 seconds to 1/4000 second, or up to 1/16000 second electronically.

Handling centers on a 2.76-million-dot, fixed (non-tilting) field-sequential electronic viewfinder offering 100% coverage and 1.39x magnification (0.7x 35mm-equivalent), along with a 3.0-inch, 1.04-million-dot tilting touchscreen LCD. A bouncible pop-up flash offers a range of approximately 6m at ISO 200, with Auto, Auto w/Red-Eye Reduction, Forced On, Forced On w/Red-Eye Reduction, Slow Sync, Slow Sync w/Red-Eye Reduction, and Forced Off modes. Built-in Wi-Fi allows for wireless image transfer and remote camera control.

Build quality centers on a compact body measuring approximately 122 x 71 x 44mm and weighing approximately 426g, with built-in stereo microphones and a mono speaker. Battery life is rated at approximately 290 shots per charge (CIPA, rear monitor) or 270 shots (viewfinder), depending on the attached lens. The GX85 uses the Micro Four Thirds lens mount, giving it access to lenses from Panasonic, Olympus/OM System, and other Micro Four Thirds alliance manufacturers.
