Panasonic GH5 II vs Panasonic GX85: A Hands-On Comparison for Serious Photographers

As someone who has tested and used hundreds of mirrorless cameras over the past 15 years, I’m often asked which Panasonic model stands out as the go-to tool for enthusiasts and professionals. Today, I’m diving deep into two popular Micro Four Thirds cameras from Panasonic’s lineup: the GH5 II, their pro-oriented flagship mirrorless model launched in 2021, and the GX85 (also known as GX80/GX7 Mark II), a well-regarded advanced mirrorless camera released in 2016.

Both offer many compelling features, but they represent different generations, price points, and user priorities. I’ll share my personal experiences alongside technical analysis and real-world performance observations to help you decide which one deserves a place in your kit.

Opening Thoughts: Form Factor and Ergonomics

Right out of the gate, you notice these cameras serve different design philosophies.

The Panasonic GH5 II is a SLR-style mirrorless body aimed squarely at professionals who require extensive handling flexibility and durability, whereas the GX85 is a rangefinder-style mirrorless camera designed to be compact, discreet, and travel-friendly.

The GH5 II measures 139x98x87mm and weighs a solid 727 grams. Its grip is deep and secure, built for long shooting sessions with heavier lenses. By contrast, the GX85 is a much more compact 122x71x44mm at only 426 grams, feeling much lighter in hand and easier to slip into a jacket pocket.

On my long outdoor shoots, the GH5 II’s robust construction gives me confidence, especially in inclement weather, while the GX85’s lightweight design is a joy on casual trips or street photography walks. Your preference here depends on your balance of portability and ruggedness.

Control Layout and User Interface

Handling comfort is inseparable from intuitive controls. The GH5 II features a traditional top-plate layout with dedicated dials and buttons that let you change crucial settings on the fly without diving into menus.

You get a comprehensive dual dial system, shutter speed, exposure compensation, and ISO controls right at the fingertips. The GH5 II favors tactile precision and fast access, critical for professionals working in demanding environments or shooting video.

The GX85 opts for a simpler control scheme befitting its advanced amateur target audience. While it includes exposure compensation and a mode dial, it lacks some of the dedicated wheels and customizable buttons of the GH5 II. The touchscreen interface is handy for most adjustments, but I occasionally missed quick manual control during brisk shooting situations.

Sensor Characteristics and Image Quality

Both cameras utilize Micro Four Thirds sensors sized 17.3x13mm, yielding a crop factor of about 2.1x for lenses. Despite their shared sensor format and no anti-aliasing filters - good for sharpness and resolving power - the difference lies primarily in resolution and sensor generation.

The GH5 II’s newer sensor and improved processing engine translate into better dynamic range and low-light sensitivity, with clean ISO performance up to about 3200–6400 usable in challenging conditions. The GX85 does well in good light, but noise rises noticeably past ISO 1600.

In real-world portraits and landscapes, I found GH5 II files exhibit more shadow detail and refined highlights. For example, in woodland scenes and sunsets, the extended dynamic range means fewer clipped areas and smoother tonal transitions.

Viewing and LCD Screen

A camera’s screen and viewfinder dictate how you compose and review images, especially in bright or variable lighting.

The GH5 II boasts a high-res 3-inch fully articulating touchscreen with 1,840,000 dots - excellent for creative angles and video work. The articulated design swings forward for vlogging or selfie shots - something the GX85’s simpler tilting screen cannot do.

The GX85 has a smaller, less sharp 3-inch tilting screen with 1,040,000 dots. It serves well for quick framing but feels limiting when shooting video or macro subjects requiring odd angles.

Similarly, the GH5 II provides an exceptionally detailed electronic viewfinder (EVF) with 3,680,000 dots and 0.76x magnification, enabling critical manual focus and composition in variable light. The GX85’s EVF has lower resolution at 2,764,000 dots and lacks magnification data, making it decent but not as immersive.

Autofocus and Focusing Features

Autofocus performance is a cornerstone of usability, whether you are capturing fleeting moments or controlling precise focus for portraits and macro.

The GH5 II uses a contrast-detection AF system with 225 focus points and advanced face, eye, and animal eye detection, allowing very reliable continuous tracking. It does not have phase-detection AF, but in my tests for wildlife and sports shooting, it locked quickly and smoothly even in moderate low light. The AF is notably sophisticated with focus bracketing and stacking modes, enhancing macro and landscape photography greatly.

The GX85 sports a more basic contrast-detection AF with 49 points, with face detection but no eye or animal AF support. It works well for static subjects and casual street photography but can stray on fast-moving subjects or lower light.

In practical terms, I preferred the GH5 II for action or wildlife shots where AF responsiveness and tracking are critical. For street and travel, the GX85’s system was adequate and more than capable for slower-paced subjects.

Speed and Burst Shooting

Continuity and frame rate matter for sports and wildlife. The GH5 II can shoot at up to 12 frames per second (fps) with continuous autofocus, while the GX85 caps at 8 fps.

In burst mode, the GH5 II processes files faster and buffers longer before slowdown. This difference can mean the difference between nailing the perfect wingbeat or a missed moment. The GX85 contributes sufficiently for enthusiast snapshots but won’t satisfy serious action shooters.

Image Stabilization and Video Capabilities

Both cameras provide sensor-based 5-axis image stabilization, vastly reducing camera shake and extending hand-held usability in low light and video shooting.

The GH5 II’s system is rated some of the best in its class, synchronizing perfectly with certain Panasonic lenses for enhanced stabilization. In video, it excels, offering internal 4K 60p recording with advanced codecs (H.264 and H.265), professional recording options including V-Log L profiles, and mic/headphone jacks for audio monitoring.

The GX85 offers 4K video but limited to 30p, with the older AVCHD codec also supported. It lacks audio ports and professional capture modes, reinforcing its role as an advanced but not fully professional video tool.

If video is a concern, especially multi-format recording or hybrid shooting, the GH5 II stands as a clear leader.

Build Quality and Weather Sealing

The GH5 II is built to withstand tougher environments, featuring environmental sealing, including splash and dust resistance. This is essential for landscape photographers and video professionals shooting in variable outdoor conditions.

The GX85 lacks any weather sealing, so I advise caution in wet or dusty settings. It’s better suited for casual use or fair weather trips.

Battery Life and Storage

In prolonged fieldwork, battery capacity is paramount. The GH5 II’s battery life rates approximately 400 shots per charge, which is quite competitive for a camera of its class and sensor size. Dual UHS-II SD card slots enable flexible workflow options, such as backup or overflow storage.

The GX85 offers about 290 shots per battery, less robust but suitable for casual use. It has only one SD card slot and USB 2.0 interface, comparatively slower for file transfers.

Connectivity and Extra Features

In today’s photogenic world, wireless connectivity helps workflow. The GH5 II includes Bluetooth and Wi-Fi, while the GX85 offers only Wi-Fi and no Bluetooth.

The GH5 II supports USB 3.2 Gen 1 for rapid tethered shooting and data transfer - a boon for studio work.

Price and Value Considerations

At launch, the GH5 II is priced around $1,700 USD body-only, reflecting its advanced pro-grade features, weatherproofing, and video prowess.

The GX85 was retailing near $800 USD at launch - a significant discount from the GH5 II - making it an outstanding bargain for enthusiasts stepping into Micro Four Thirds.

Real-World Shooting Across Genres

I spent extensive time field-testing both cameras across these photography types:

Portrait Photography

The GH5 II’s 20MP sensor produces crisp images with subtle skin tone rendition, augmented by eye and face detect AF that locks quickly for sharp portraits - even animals.

The GX85’s 16MP sensor and basic AF handle portraits well enough under good light but are less forgiving in complex lighting or shallow depth-of-field scenarios.

Both lack a true full-frame’s natural shallow depth, though Panasonic’s lens ecosystem offers fast primes that produce nice bokeh.

Landscape Photography

The GH5 II shines here with high dynamic range and articulating screen aiding composition in rugged environments. Weather sealing means less worry about the elements.

The GX85 is fine for casual landscapes but limited by less dynamic range and no weatherproofing.

Wildlife and Sports Photography

The GH5 II’s high fps, robust AF tracking, and weather sealing make it suited for fast action and outdoor wildlife shooting.

The GX85 struggles to keep up with fast movers given its slower AF and frame rates.
