Panasonic Lumix GX9 vs GX85: A Hands-On Comparison for Serious Photographers

Over the last decade, Panasonic’s Micro Four Thirds (MFT) cameras have earned a solid following among enthusiasts and professionals seeking compact, versatile bodies with strong imaging capabilities. Two popular advanced mirrorless models that frequently come up in discussions are the Panasonic Lumix GX9 and GX85 (known as the GX80 in some regions). These siblings share many attributes – from sensor size to lens compatibility – yet each brings nuanced strengths that will appeal differently depending on your shooting style and priorities.

Having tested both extensively across varied photographic disciplines, I’ll walk you through a side-by-side look at what truly sets them apart, and help you figure out which is the better investment for your creative journey.

A Quick Look: Size, Handling, and Build

Ergonomics often dictate how enjoyable a camera feels during long shoots, so let’s kick off by examining their physical form.

Right away, you’ll notice the GX9 is marginally larger and heavier at 407g compared to the GX85’s 426g. While the GX85 is slightly thicker, the GX9’s more rounded body and improved grip make it more comfortable especially for extended handheld use. Panasonic designed the GX9 with a bit more heft and refined contours for better balance with larger lenses.

Looking from the top:

The control layout shows incremental improvement on the GX9 - a dedicated ISO dial nestled beside the shutter, plus an additional customizable Fn button. The GX85 feels a bit more minimalist but still functional with well-placed dials and buttons. Both offer a tilting 3-inch touchscreen, but the GX9’s screen boasts a higher resolution at 1240k dots versus 1040k on the GX85, making menu navigation and focus peaking clearer in challenging light.

Personally, I prefer the GX9’s slightly refined ergonomics. That tiny weight difference, coupled with a more substantial handgrip and that neat extra dial, makes a noticeable difference during all-day shoots or on the street.

Sensor and Image Quality: More Than Meets the Eye

Both cameras use a Four Thirds-sized CMOS sensor measuring 17.3 x 13mm, supporting the vast Micro Four Thirds lens ecosystem of over 100 lenses - a real plus if you’re considering telephoto, macro, or slow-focus lenses.

The GX9 offers a 20MP resolution sensor, a bump over the GX85’s 16MP chip. That’s not just pixels on paper: in my tests, you’ll find the GX9 produces slightly better-defined images with a bit more mid-tone gradation and improved fine detail, especially visible when cropping or printing large.

Interestingly, both cameras lack an anti-aliasing filter; this absence enhances detail rendition but sometimes risks moiré in fine patterns - an expected trade-off in mirrorless sensors today.

In terms of dynamic range, neither body sports headline-grabbing improvements over the other - but the GX9 shows a slight edge in shadow recovery and highlight retention, which becomes valuable in landscape and outdoor portrait shooting.

Low-light performance is also closely matched, with native ISO ranges maxing at 25,600. Panasonic’s Venus Engine processor handles noise reduction effectively on both, although the GX9’s sensor and newer processing yield marginally higher ISO usability - expect cleaner frames at ISO 3200 and above.

Autofocus Systems: Speed and Accuracy Tested in the Field

Autofocus tech can make or break your experience, particularly if you shoot fast-moving subjects or rely heavily on face/eye detection.

Both cameras feature contrast-detect autofocus complemented by some phase-detection points (the GX9’s autofocus boasts hybrid PDAF, while the GX85 relies solely on contrast detection). The number of focus points is similar at 49.

Practically, the GX9’s AF system is smoother and snappier. Continuous autofocus tracking scores particularly well in my action and wildlife tests - it manages to lock and maintain focus on erratically moving subjects better than the GX85. This is partly due to the LG sensor design improvements and processing upgrades.

Moreover, both cameras support eye detection AF, but neither offers animal eye detection, which professionals wanting dedicated pet or wildlife portraits might find limiting. Still, the GX9’s improved AF tracking feels distinctly more reliable during sports or candid street scenarios.

Viewing Experience and User Interface

Looking through the eyepiece or reviewing your shots matters a lot - here, Panasonic took a measured approach.

Both the GX9 and GX85 sport electronic viewfinders (EVF), boasting full 100% coverage and similar resolutions (~2760k dots).

Where they differ is in ergonomics: the GX9’s EVF placement and slight bump in magnification (0.7x vs no rating on GX85) provide a better “window” feel, helping reduce fatigue and enabling precise framing. The bigger screen resolution on the GX9 also enhances the touch interface experience - pinch-to-zoom, menu navigation, and touch-to-focus are a breeze on both, but crisper on the GX9.

Menus may look familiar to Panasonic users, staying consistent between models, but I found the newer UI tweaks on the GX9 reduce distractions and speed up image review or mode switching, especially for hybrid shooters who move fluidly between photo and video.

Versatility Across Different Photography Genres

The true test of any camera lies in how well it performs under the varied demands of portraiture, landscapes, wildlife, and beyond. I’ll break down how each camera fares in specific use cases, drawing on real-world shooting and laboratory tests.

Portrait Photography: Skin Tones and Bokeh

Both cameras leverage Panasonic’s sensor design and image processor to reproduce natural skin tones. However, the GX9’s extra resolution gives you sharper portraits especially noticeable at wider apertures.

While neither has in-body lens aperture controls, the GX9 supports focus bracketing and post-focus software features that aid creative focus stacking - a boon for macro/detail work often needed in beauty shots.

The Micro Four Thirds sensor size means depth of field control won’t rival full-frame cameras, but Panasonic’s sharp lenses combined with the GX9’s subtle improvements yield smoother subject-background separation. The subtle upgrade in autofocus eye detection responsiveness on the GX9 also reduces missed focus on human subjects.

Landscape Photography: Dynamic Range and Durability

Landscape shooters prize dynamic range and high-resolution files. The GX9's 20MP sensor provides an advantage here.

Though neither camera has environmental sealing (a common omission in this category), the GX9's build feels marginally more robust and suited for conditions where dust or moisture might sneak in, provided you use weather-resistant lenses.

The tilting touchscreen facilitates tricky shooting angles - ideal for hand-held or tripod work on uneven terrain.

Above you can see comparative sample images - notice the GX9’s greater clarity and slightly punchier colors, especially in high-contrast scenes.

Wildlife and Sports Photography: Autofocus and Burst Rates

Fast subjects need fast gear. The GX9 delivers 9 frames per second (fps) continuous shooting - just edging out the GX85’s 8 fps. That might seem insignificant, but in action, a faster burst rate translates to better “keeper” chances.

Combine this with the GX9’s hybrid autofocus for more reliable tracking, and it becomes the preferable option for wildlife and sports shooters on a budget.

Do note, however, that neither has a full-frame sensor or professional-grade autofocus systems found in flagship bodies, so compromises remain for serious pro sports or wildlife photographers.

Street Photography: Portability and Low-Light Discretion

For street shooters, discretion and lightweight build are paramount. Here, the GX85’s slightly smaller and thinner profile may appeal more.

Despite the minor ergonomic advantages of the GX9, the GX85 is a stealthy companion, especially when paired with pancake lenses.

Both excel in low light with 5-axis in-body stabilization and sensitive ISO ranges, allowing for handheld shooting at slower shutter speeds without worry.

Macro and Close-Up Photography: Precision Comes First

Micro Four Thirds users have access to excellent macro lenses, and both cameras support focus stacking, focus bracketing, and post-focus modes – ideal for precision close-ups.

The improved sensor resolution on the GX9 benefits pixel-level detail capture, but the GX85’s excellent 5-axis stabilization also makes handheld macro shooting comfortable.

If you often shoot handheld close-ups of insects, flowers, or products, the GX9’s subtle autofocus edge may give you faster results.

Night and Astro Photography: High ISO and Exposure Control

Night photography is one of the toughest tests for any camera.

The lack of environmental sealing in both models requires extra care, but both deliver respectable high ISO performance up to 6400 usable limits.

The GX9’s newer sensor and processor enable slightly cleaner images at very high ISO, reducing chroma noise.

Manual exposure modes, bulb shooting, and long exposure support are present on both, supplemented by 5-axis stabilization.

But I found the GX9’s interface easier to adjust ISO and shutter speed on the go, minimizing distractions under dark sky conditions.

Video Capabilities: Detail and Stability in Motion

If video is your game, both cameras share 4K (UHD) recording capabilities at 30p and 24p, with H.264 codec support.

The GX85 supports 4K at up to 30fps and 1080p up to 60fps. Notably, the GX9 offers 4K Photo mode - great for capturing perfect moments in challenging settings - and improved 5-axis sensor stabilization works well for handheld video.

Neither camera provides microphone or headphone jacks, limiting audio refinement options. Still, for casual or enthusiast videographers, both produce sharp, well-stabilized footage.

Travel Photography: Portability, Battery, and Connectivity

Travelers want a camera that balances quality with size, weight, and battery stamina.

The GX85’s lighter body and slimmer profile slightly tilt the scale in its favor for portability. However, you trade some ergonomic comfort.

Battery life differences are notable: the GX85 can squeeze roughly 290 shots per charge, while the GX9 offers around 260, though real-world usage depends on power-hungry EVF use and image reviewing habits.

Wireless features also differ slightly: the GX9 packs Bluetooth connectivity for faster pairing and lower battery drain remote control, absent on the GX85.

Single SD card slots support UHS-I speeds on both.

Professional Workflows: Reliability and Flexibility

For professional work, file quality, workflow integration, and reliability matter.

Both cameras shoot DNG RAW files, and the GX9’s sensor delivers higher resolution, aiding in large prints or commercial applications requiring cropping flexibility.

Build quality, while solid, is not professional-grade weather sealed.

You get all expected exposure modes, white balance bracketing, and customizable buttons on both; the GX9’s additional ISO dial and Fn1-3 buttons offer more real-time control.

Considering overall capabilities, the GX9 ranks slightly higher across core performance metrics, particularly in image quality, autofocus, and user controls.

Genre-specific breakdown reveals the GX9 shines best for portrait, sports, and landscapes, while the GX85 remains competitive in street, travel, and macro niches.

Technical Deep Dive: Processor, Sensor, and Stabilization

Underlying both bodies is Panasonic’s Venus Engine processor, important for noise management and speed.

The GX9 includes a more recent iteration, contributing to better image processing and video compression efficiency.

Both employ sensor-based 5-axis image stabilization - excellent for handheld shooting - but field tests consistently show the GX9 is slightly more effective, especially at longer focal lengths.

Both use the same Micro Four Thirds mount, accessing the vast array of lenses Panasonic and Olympus offer.

Price to Performance: What You Get for Your Money

As of now, the GX85 retails roughly at $799.99, whereas the GX9 sits closer to $999.99. For a $200 premium, you gain higher resolution, improved autofocus, enhanced handling, and Bluetooth connectivity.

If your photography demands catch these nuances - like sports shooting or detailed portraiture - the GX9 justifies the investment.
