Panasonic GX9 vs Panasonic G6: A Hands-On Comparison by a Seasoned Camera Tester

When stepping into the Micro Four Thirds (MFT) realm, Panasonic always looms large, offering cameras that suit a wide range of users - from total beginners to hardened pros. Today, I’m diving deep into two of their gems: the Panasonic Lumix GX9, announced in 2018, and the older, popular Panasonic Lumix G6 from 2013.

Having tested both extensively under my photographer’s steely gaze, I’ll break down what separates these two, where they excel, and who should consider each. Whether you’re hunting for your first mirrorless or looking to upgrade without breaking the bank, this guide has you covered.

Size, Handling, and Build: What’s it Like to Hold These Cameras?

If ergonomics were a sport, the GX9 would be playing in the premier league while the G6 is more your reliable club team.

The GX9 sports a compact, almost rangefinder-style body that is a bit smaller in width and thickness but a tad taller than the G6’s more traditional DSLR-ish shape. Its clean, minimalist styling gives off a refined vibe that’s surprisingly ergonomic given its size.

The G6, on the other hand, is chunkier (and I mean in a good way) with an SLR-style grip shaped for firm handling. For larger hands or longer sessions, this might feel better, especially when paired with heavier lenses.

From my workload – shooting street, landscapes, and portraits – the GX9 felt lighter and less obtrusive during long handheld trips. The G6’s grip made it steadier especially for action-type photography but could occasionally feel a bit bulky in tight street shoots.

Tactile feedback-wise, both use robust plastic with some metal, but only the GX9 steps up with moisture resistance sealing - minute, but worth considering if you occasionally brave the elements.

Controls on the GX9 are modern, with streamlined dials and fewer buttons - great for those who dislike clubs for thumbs cluttering the body. The G6 is more button-rich and mode-dial oriented, catering more to manual shooters who love quick physical access to settings.

If you’re a fan of customizable controls, the GX9 handily wins here, letting you tailor the camera’s buttons better to your shooting style.

Sensor and Image Quality: Resolution, Dynamic Range, and ISO Performance

The shooter's heart beats here. Both cameras feature the classic Four Thirds-sized sensor measuring 17.3 x 13 mm, but what lies beneath is quite different.

The GX9 boasts a 20MP sensor without an anti-aliasing filter (AA filter), a detail that usually translates to sharper images - but sometimes at a risk of moiré in patterned subjects. The G6’s 16MP sensor includes an AA filter which mildly softens images but helps avoid those unwelcome artifacts.

In side-by-side raw file tests, the GX9 churns out images with more fine detail and richness, while the G6 holds its own but shows a bit less pop, especially when details matter (think landscape rocks or fine hair strands in portraits).

Dynamic range, as per DxO's assessments and my own lab-style exposures, leans slightly higher for the GX9 - roughly a stop or so better under RAW editing conditions - meaning you can pull shadows and highlights more gracefully.

When it comes to high ISO noise, the GX9 again outperforms the G6, especially from ISO1600 upwards. Shooting indoors and at night, the GX9 maintains cleaner images with more color fidelity.

Bottom line: Serious image quality seekers get a tangible upgrade with the GX9 sensor, especially in resolution and noise handling.

Autofocus Systems: Precision vs Speed for Every Click

Autofocus can make or break your shot in the real world. Both cameras use contrast-detection AF, but their approaches and performance vary.

The GX9 features Panasonic’s hybrid AF system, combining contrast and a limited phase-detection array across 49 focus points. It supports continuous tracking, single AF, face detection, and selective AF modes, with touch-to-focus on the screen.

The G6 relies solely on contrast detection with 23 points, lacking phase detection and thus generally slower AF response and more occasional hunting - especially in lower light.

In real-world wildlife and sports scenarios - where focusing speed is king - the GX9 locks on noticeably faster and tracks moving subjects more confidently. It also supports better face and eye-detection autofocus, helping portrait shooters nail those sharp eyes. The G6 can falter here, especially in challenging light or with busy backgrounds.

I tested both in street photography situations (moving people, fast in-and-out frames): the GX9’s AF was definitely less prone to delays, allowing me to capture candid moments with less stress.

While neither model features Panasonic’s latest animal eye AF (available on newer cams), the GX9’s improved AF chip gives it a solid edge overall.

Build Quality and Weather Sealing: Ready for Adventures?

If your adventures often include rain, dust, or dusty trails, this is a key aspect.

Neither the G6 nor the GX9 is classified as fully weatherproof or freezeproof. However, the GX9 shows modest environmental sealing around buttons and dials - nothing rugged-professional tough, but better than the G6’s open design.

Both are dust- and splash-resistant, but I’d still recommend a rain cover for heavy downpours in either case.

The G6 is bulkier thanks to its design, which may provide a small buffer from knocks or bumps. The GX9 is smaller and slicker, which requires a bit more care.

Display and Viewfinder: How You Frame Matters

Both cameras sport 3-inch LCDs with touch capability - but here the differences matter for users who crave flexibility.

The GX9 has a tilting screen with 1240k-dot resolution, sharp and bright, tilting up and down but not fully articulated. Meanwhile, the G6 features a fully articulated (flip-out) TFT LCD screen with a lower resolution (1036k dots) but wide viewing angles - super handy for vloggers and macro shooters needing creative angles.

For my video experiments and funky overhead macro shots, the G6’s fully articulated screen was more convenient. But for straightforward composition and quick framing, the GX9’s sharper tilt screen offers better brightness and responsiveness.

Both have electronic viewfinders (EVFs), but the GX9’s EVF is a standout:

• GX9’s EVF: 2.76M dots, 0.7x magnification, 100% coverage
• G6’s EVF: 1.44M dots, 0.7x magnification, 100% coverage

The GX9’s EVF is crisper with less lag, which is huge when shooting fast action or adjusting manual focus rings precisely.

Lens Compatibility and System Ecosystem: The Micro Four Thirds Advantage

Both cameras use Micro Four Thirds mounts, giving access to an enormous lens ecosystem - the same collection of 107+ lenses from Panasonic, Olympus, and third-party makers.

Whether you want fast primes for portraits, super-teles for wildlife, or tiny macros, you’re covered equally on both. If you lean towards newer lenses with better performance and IS (image stabilization), these will pair exceptionally well with the GX9.

That said, with the GX9’s in-body 5-axis stabilization, you benefit even when your lens lacks IS, which is a significant practical gain. The G6 lacks IBIS (sensor-shift stabilization), so you’ll be dependent on lens stabilization alone.

Lens choice doesn’t really favor one model over the other, but image stabilization and newer firmware compatibility tilt the balance slightly towards the GX9.

Continuous Shooting and Buffer: Catching the Action

Sports and wildlife photographers often obsess over frame rates and buffer depth.

• GX9: Up to 9 fps continuous shooting (mechanical shutter), silent shutter up to 16,000th sec
• G6: Up to 7 fps continuous shooting (mechanical shutter)

The difference of 2 fps may not seem earth-shattering but can make the difference between capturing the decisive moment or a blurred miss, especially at fast-moving events.

Buffer depth wasn’t officially published for the GX9 but I noted it manages about 20 RAW frames before slowing - enough for typical bursts. The G6’s buffer is smaller, occasionally forcing you to wait before re-shooting, especially with RAW files.

If you photograph kids, sports, or wildlife, the GX9 handles the heat better.

Video Capabilities: Beyond Still Photography

If video is part of your creative diet, the GX9 leaps ahead in specs:

• GX9 shoots 4K UHD (3840 x 2160) up to 30p, with 4K photo modes (extracting 8MP stills from video).
• G6 maxes out at 1080p Full HD (1920 x 1080) in various frame rates up to 60p.

The GX9 is better suited for hybrid shooters who want both stills and crisp video footage.

Microphone inputs? The G6 has a microphone port, which is a nice plus for vloggers and interviewers, while the GX9 lacks this, limiting external audio options.

Neither has headphone jacks, so audio monitoring is limited in both.

Megapixel advantage and 4K video make the GX9 the better choice if video production plays a big role in your workflow.

Battery Life and Storage: Keeping the Camera Running

Battery life can be the Achilles heel of tiny mirrorless cameras.

• GX9: Rated ~260 shots per charge
• G6: Rated ~340 shots per charge

Despite its modern features, the GX9’s battery life is slightly shorter due to high-res EVF and faster continuous shooting.

Neither will impress pros shooting all day without spare batteries, but casual users should be okay with one fully charged.

Both cameras use a single SD card slot compatible with SD, SDHC, and SDXC (UHS-I supported). Storage speed helps with video and burst shooting but is largely a tie here.

Connectivity: Wireless and Ports

On wireless tech:

• GX9 offers built-in Wi-Fi and Bluetooth for image transfers and remote control via smartphone apps.
• G6 has Wi-Fi and NFC but no Bluetooth.

Bluetooth helps with quicker pairing and background transfers, giving the GX9 an edge here.

In terms of ports:

• Both have HDMI outputs.
• The G6 includes a microphone input, which the GX9 lacks.
• USB connectivity: GX9 supports USB 3.1 (faster), G6 uses USB 2.0.

These differences might sway those who prioritize streamlined workflow or sound recording needs.

Practical Shooting in Different Genres: Here’s What Really Counts

I took both cameras across various shooting scenarios to assess real-world performance. Here are my detailed impressions.

Portrait Photography

The GX9’s 20MP sensor, superior AF with face and eye detection, and pleasing color science lift portrait quality. Bokeh is nice but limited by the smaller MFT sensor size and lens choice.

The G6 produces decent portraits but misses the quicker eye detection and sharper details. Its lower resolution can be a slight drag if you want heavy cropping.

Winner: GX9 for sharper images and reliable focus.

Landscape Photography

Both are capable with rich color rendition and decent dynamic ranges for MFT sensors.

The GX9 edges ahead with its higher dynamic range, no AA filter for crisp detail, and better high ISO performance for moody, late-day shots.

Weather sealing gives it a small durability advantage for field use too.

Winner: GX9

Wildlife and Sports Photography

GX9’s faster continuous shooting, better AF tracking, and improved buffer capacity win out here. The G6’s 7 fps and contrast-only AF can frustrate fast-action shooters.

Plus, GX9’s silent shutter (up to 1/16000s) helps capture shy animals without noise.

Winner: GX9

Street Photography

Size and discretion matter a lot here.

GX9’s compact rangefinder style and lighter body make it far less conspicuous, perfect for candid street imagery. Its quick AF and tilting screen facilitate shooting from the hip or awkward angles.

G6 is bulkier and less stealthy, though the fully articulated screen is handy.

Winner: GX9

Macro Photography

Here, the G6’s fully articulating screen and microphone input (for accessory lighting/audio) might appeal to macro enthusiasts who film their work.

No IBIS means GX9 depends more on stabilized lenses or tripods, but its focus stacking and focus bracketing features are powerful tools for close-up shooters.

Winner: Tie, depending on focus stacking need vs ease of composition

Night and Astro Photography

The GX9’s better high ISO performance and higher resolution sensor help extract more detail in dark conditions. Its built-in 5-axis stabilization is a plus for handheld night shots.

G6 is hampered by older sensor tech, more noise, and no IBIS.

Winner: GX9

Video Work

If 4K video is important, the GX9 clearly wins with its higher resolution and 4K photo modes.

G6 offers microphone input - not trivial for pros - but maxes out at 1080p.

Winner: GX9 for video quality; G6 for audio input

Travel Photography

In travel, you want a lightweight but versatile camera.

GX9’s smaller size, better image quality, 5-axis stabilization (handheld versatility), and wireless connectivity make it easier to pack and shoot on the move.

G6 offers longer battery life but bulkier handling.

Winner: GX9

Professional Usage

For professional photographers, RAW support, reliable AF, file format flexibility, and workflow integration matter.

GX9 supports RAW, custom white balance, focus bracketing, and post-focus features - all excellent pro tools. Plus, USB 3.1 and Bluetooth help faster transfers.

G6’s older USB 2.0 and lack of focus bracketing make it less efficient for professional workflow.

Winner: GX9
