Panasonic GX85 vs Sony NEX-6: An Expert’s Hands-On Mirrorless Showdown

When you're hunting for a capable mirrorless camera that punches above its weight, both the Panasonic Lumix GX85 and the Sony Alpha NEX-6 have earned their places in enthusiasts’ kits. Released a few years apart, these two models - each represent a sweet spot for advanced shooters who want quality without breaking the bank. Having spent time with both, shooting a range of genres (portraits to street to wildlife), I’m excited to unpack their strengths, weaknesses, and make recommendations grounded in solid hands-on experience and technical analysis.

Let’s start by getting a sense of their physical presence and ergonomics, an often overlooked but critically important aspect when decision time comes.

First Impressions Matter: Size, Feel & Handling

Right away, the Panasonic GX85 and Sony NEX-6 show some family resemblance in their rangefinder-style mirrorless frames, but subtle differences affect comfort and handling. The GX85 (122x71x44mm, 426g) is just a tad chunkier and weightier than the compact NEX-6 (120x67x43mm, 345g), which will matter if you’re a travel photographer or street shooter who prefers to stay nimble.

My firsthand tests show the GX85’s slightly larger grip offers more confidence during extended handheld shooting - especially useful for burst-heavy wildlife or sports sessions. Though, if you’re a cheapskate looking for a carry-anywhere solution, the Sony’s lighter frame slides into smaller bags and pockets with less fuss.

Both cameras employ a tilting 3-inch LCD screen for composition versatility, but more on those controls in a moment.

Getting a Good Grip on Controls and Interface

If you like clubs for your thumbs and body-mounted dials for rapid adjustments, the GX85 feels more modern and tactile, boasting intuitive, well-placed buttons alongside a rear command dial that’s snappy and suited to quick shutter speed and aperture tweaks.

Sony’s NEX-6 attempts a clean design, though without a top LCD display or dedicated exposure compensation dial, which in fast-paced shooting can slow you down as you wander menus or reach for the rear dial.

The GX85’s touchscreen capabilities add another layer of user friendliness that the NEX-6 lacks. Touch-to-focus and menu navigation on the GX85 are not merely gimmicks but practical features I appreciated during dynamic shooting scenarios - particularly when framing moving subjects in wildlife photography.

The Heart of the Matter: Sensor Size & Image Quality

Now, onto one of the biggest technical distinctions: sensor size. The Sony NEX-6 rocks a larger APS-C sensor (23.5x15.6mm) compared to the Micro Four Thirds sensor in the Panasonic GX85 (17.3x13mm). At face value, that bigger sensor generally translates to better light-gathering ability, lower noise at high ISOs, and more dynamic range potential.

DxOMark’s analysis confirms this: the NEX-6 scores an overall 78, edging out the GX85’s 71. It shines particularly in color depth (23.7 vs 22.9) and dynamic range (13.1 EV vs 12.6 EV). This means richer tones and better highlight/shadow retention in raw files from the Sony.

But before you write off the GX85, know that its sensor still punches way above its weight in Micro Four Thirds territory - especially considering no anti-aliasing filter increases sharpness slightly. And in practical terms, Panasonic's 5-axis in-body sensor stabilization (which the Sony lacks) allows slower shutter speeds handheld, reducing blur in low light - a nice mitigating factor when high ISO noise creeps up.

Eye on Autofocus: Speed, Accuracy, and Usability

Autofocus is the spiderweb that determines how often you capture the decisive moment versus missed shots. Let me break down my observations through different shooting types.

The Sony NEX-6 boasts a hybrid AF system comprising 99 phase detection points and contrast detection, a cutting-edge combo in 2013, excellent in daylight but sometimes inconsistent in tracking moving subjects - especially since it lacks advanced continuous tracking. I noticed it struggled mildly in sports shooting with fast athletes or birds in flight, losing focus briefly.

Panasonic’s GX85 employs a contrast-detection-only system with 49 focus points, which some might label dated; however, it compensates via depth from focus stacking, post-focus modes, and superb face detection. Low light AF still lags behind Sony’s system, but the GX85 surprises with highly reliable eye detection in portraits, which becomes invaluable when you want pixel-perfect skin tones and sharp eyes for headshots or client work.

For wildlife or action shooters craving blazing speed and tracking, neither camera is best in class today - but the Sony's faster burst rate of 10fps versus Panasonic’s 8fps gives it a slight edge.

Real-World Portrait and Landscape Performance

Portraits: Skin tones and Bokeh

Both cameras produce pleasing skin tone rendition with their natural color science and ability to shoot in RAW to fine-tune subtle nuances.

The GX85's Micro Four Thirds sensor, paired with Panasonic’s multitude of native primes and f/1.2-f/1.8 lenses, is excellent for creamy bokeh - especially given the sensor stabilization allowing sharper shots at wider apertures. The absence of an anti-alias filter aids perceived sharpness, making eyes pop.

The Sony’s larger sensor provides shallower depth of field at equivalent apertures, which photographers craving dreamy backgrounds in portraits might prefer. However, Sony’s Anti-Aliasing filter softens that effect slightly but helps reduce moiré.

Landscapes: Resolution and Dynamic Range

Panasonic’s 16MP sensor offers ample resolution (4592x3448) for vivid printing up to A3 or detailed web usage, but the NEX-6 gives 4912x3264 pixels in a slightly wider 3:2 aspect ratio, which felt a touch better for cropping flexibility.

On location, the NEX-6’s superior dynamic range was evident in tricky sunrise shots where I could recover shadows without crushing highlights. The GX85 held its ground but sometimes needed more care in highlight-heavy scenes.

Weather sealing is a sore point for both: neither camera is truly rugged or dustproof, so landscape shooters facing tough conditions must protect them with shells or bags.

Wildlife and Sports Shooting: Burst and Telephoto Compatibility

Neither the GX85 nor NEX-6 are full-blown sports shooters, but their mirrorless designs and lens ecosystems make them viable for casual wildlife enthusiasts.

With a 2.1x crop factor on the GX85 versus 1.5x on the NEX-6, Panasonic users get added reach with tele zoom lenses - useful for birding or shy critters without lugging big glass. Be mindful real image quality falls off past 300mm equivalents, but this can mean the difference between you and the squirrel disappearing behind foliage.

Sony edges Panasonic on continuous shooting at 10fps, which is key for capturing fleeting sports action. However, the GX85’s 5-axis stabilization helps steady telephoto shots handheld better, reducing reliance on tripods or monopods.

For autofocus tracking, Sony’s hybrid AF is marginally faster but sometimes less consistent, while Panasonic's contrast-AF requires practice but shines if you use focus lock and preemptive tracking techniques.

Street and Travel: Discreteness, Portability, and Battery Life

Street photographers love discreet, unobtrusive gear. The Sony NEX-6, being slightly smaller and lighter, fits the bill better here. It’s easier to hold low and shoot candidly.

While the GX85’s touchscreen and fully articulating LCD give it a leg up for awkward angles or overhead shots, the Sony’s ‘Xtra Fine’ screen produces excellent clarity for composing in bright sunlight despite lacking touch controls.

In battery life, the NEX-6 lasts longer - up to 360 shots vs the GX85’s 290. When traveling, that difference can dictate how often you need to recharge or carry spares.

On the wireless side, both cameras include built-in Wi-Fi for quick image transfers, handy for social media hungry travelers. Neither have Bluetooth or NFC, so pairing is manual.

Macro and Night/Astro Photography

If you’re into close-up work, neither camera offers dedicated macro features, but the GX85’s focus stacking mode stands out. This lets you shoot multiple images at different focus distances and combine them for greater depth. Not many cameras in this price range offer post-focus stacking - it’s a creative boon.

The NEX-6 doesn’t have such modes but does have a robust macro lens lineup on the Sony E mount.

Night and astro photographers will appreciate the Panasonic’s 5-axis sensor stabilization for longer handheld exposures, though an equatorial mount is still recommended for stars. The GX85 ISO performance maxes out at 25600 native but is better optimized through the Venus Engine.

Sony’s sensor shines at high ISO with objectively less noise (DXO low light score 1018 vs 662), making cleaner starscape snaps with less post-processing needed.

Video Capabilities: 4K and Beyond

If video shooting matters to you, the GX85 pulls a clear win.

Panasonic was ahead of the curve offering 4K video at 30p and 24p, along with 4K photo modes that let you extract high-res stills from video frames. This is a feature I’ve used extensively for event shooting when unexpected still moments arise.

On the other hand, Sony’s NEX-6 is limited to 1080p HD video max, which is decent but now feels a step behind in an era where 4K is becoming standard.

Neither camera features microphone or headphone jacks, which disappoints serious videographers, but on-camera mic inputs can often be added with accessories.

Professional Use: Reliability, Formats, and Workflow

Both cameras shoot in RAW and support major formats like AVCHD and MPEG-4 for video, important for integrating into professional workflows.

Build quality is solid but not weather sealed, so professionals shooting in unpredictable conditions must plan accordingly.

Connectivity options are similar, with HDMI and USB 2.0 ports present, enabling tethered shooting and easy file transfers.

The GX85’s advanced customization options (like focus bracketing and post-focus) provide more luxury for precise control - even if not a deal-breaker for studio or event pros.

Putting a Price Tag on Performance and Value

At around $365 new or often less used, the Sony NEX-6 represents a tremendous bargain for APS-C image quality and size-conscious users on a tighter budget.

The GX85 hovers around $800 but packs modern conveniences like 4K, in-body stabilization, and a more advanced AF system that justify the premium for users who want these features.

How They Stack Up Across Photography Genres

Final Thoughts: Which One’s Right for You?

If you asked me to carry just one for a multi-day hike through varying light and subject matter - portraits, landscapes, the occasional wild critter - the Panasonic GX85 would be my pick hands down. The combination of 4K video, real in-body stabilization, and a better control interface means fewer missed shots and smoother hand-held video. Its smaller sensor is a manageable compromise, especially given the lens ecosystem and powerful post-focus features.

But if your budget’s tighter, you crave larger sensor image quality, and weight and size are critical (think street shooters or casual travelers), the Sony NEX-6 remains a solid, highly affordable alternative. Its APS-C sensor delivers richer files and better noise control at high ISO, essential when available light gets stingy. The drawback is fewer modern conveniences like 4K video and image stabilization, which might tip the scales based on your priorities.
