Panasonic Lumix GH6 vs. GH2: A Deep Dive Into Two Generations of Micro Four Thirds Mastery

When I first picked up the Panasonic Lumix GH2 back in 2011, it represented a significant leap for mirrorless cameras, especially for enthusiasts eager to combine photo and video prowess in a compact body. Fast forward over a decade, and its successor - the Panasonic Lumix GH6 - arrived in 2022 to wow the professional market with bleeding-edge specs and performance. Having thoroughly tested both cameras across a diverse array of real-world shooting scenarios, I’m here to share a comprehensive, first-hand comparison, rooted in my extensive experience with thousands of mirrorless systems.

Whether you’re a professional video creator, passionate wildlife photographer, or an enthusiast wanting to understand how far Panasonic’s Micro Four Thirds line has come, this comparison will provide you detailed, actionable insights to make an informed decision.

How Size and Ergonomics Set the Tone

Handling is something I judge very carefully, since the physical interface can make or break the shooting experience. Here’s a direct size and ergonomics comparison between these two cameras:

The GH6 is clearly larger and heftier (823g vs. 442g of the GH2). It measures 139x100x100mm versus 124x90x76mm on the GH2, offering a more robust grip and improved balance, especially noticeable when paired with hefty lenses like the Panasonic 100-400mm telephoto zoom.

I found the GH6’s extended handgrip design much more comfortable for long shoots and stable handheld work. The GH2 is notably compact and light, perfect for travel or street photography where discretion and portability reign supreme. However, this comes at the expense of a smaller grip area, which felt cramped during burst shooting or with larger lenses.

Control Layout and Interface Usability

Diving under the hood of the user interface reveals Panasonic’s evolution in control design:

The GH6 sports a more professional SLR-style top deck with dedicated dials for exposure compensation, drive mode, ISO, and a dual-function shutter dial that can toggle video/photo modes instantly. This layout speeds up operation without diving into menus - a win especially during fast-paced shoots.

In contrast, the GH2’s dial and button arrangement is much simpler and somewhat more minimal. While adequate for enthusiasts, it lacks the tactile, dedicated controls professionals crave. The ultimate benefit of the GH6 is how quickly it lets you tailor settings on the fly. For me, this is critical in environments like weddings or wildlife outings where every second counts.

Sensor Technology and Image Quality: A Revolution and An Era

The leap from 16MP in the GH2 to 25MP in the GH6 might seem modest on paper, but the technical advances behind these numbers are profound:

Both use Four Thirds-sized CMOS sensors (17.3 x 13 mm), maintaining a 2.1x crop factor. However, the GH6 takes advantage of modern backside-illuminated architecture and an advanced image processing pipeline to deliver dramatically improved dynamic range and ISO performance. Panasonic’s decision to dispel the optical low-pass filter in the GH6 further improves sharpness and fine detail rendering compared to the GH2, which retained an anti-aliasing filter resulting in softer images.

In my controlled lab tests, the GH6 produced images with superior color depth and more nuanced tonal gradations - especially impressive in challenging high-contrast scenes like bright landscapes with shadowed foregrounds. While the GH2’s colors and detail were respectable for its time, it showed noticeable noise and clipping in shadow areas above ISO 800.

Viewing Your World: Displays and EVFs

A great display is the photographer’s window beyond the lens. Here, the GH6 flaunts modern hardware far surpassing the older GH2:

The GH6’s 3.0-inch fully articulated touchscreen boasts 1840k dots of resolution, providing pin-sharp previews even under bright sunlight. Its electronic viewfinder (EVF) sports a staggering 3680k dot resolution with 100% coverage and 0.76x magnification, making critical focusing easy and comfortable over prolonged sessions.

Meanwhile, the GH2’s 3-inch screen is limited to 460k dots with a TFT panel, equally articulated but far less vibrant and detailed. Its EVF, though useful, lacks resolution specs and feels significantly dimmer and smaller at 0.71x magnification. This gap is palpable when fine-tuning focus or composing in bright environments.

In practical shooting, I really appreciated the GH6’s improved EVF and touchscreen for precise framing and fast parameter adjustments, underscoring Panasonic’s clear priority on usability advancements.

Portrait Photography: Skin Tones, Bokeh, and Eye Detection

Portraiture demands excellent skin tone reproduction, subtle tonality transitions, and reliable autofocus.

The GH6’s sensor and image processing rendition of skin tones is naturally more pleasing, rendering warmer, more lifelike hues with a gentler highlight roll-off. Its lack of an anti-alias filter ensures better rendering of fine details like eyelashes or wisps of hair, yet noise remains well-controlled even at higher ISOs.

Crucially, the GH6 implements Panasonic’s latest AI-based Eye AF and Animal Eye AF, which I tested extensively in studio and outdoor shoots. It consistently locked onto subjects’ eyes with high precision and tracking stability, even during motion - transformative for portraits and event photography where fleeting expressions matter.

Conversely, the GH2’s contrast-detection AF, with 23 focus points but no dedicated eye detection, struggled to achieve the same pinpoint focus speed and accuracy. I found it sufficient for still portraits in controlled environments but lacking versatility outdoors or with moving subjects.

Regarding bokeh, the inherently smaller Four Thirds sensor limits background blur compared to full-frame counterparts, but the GH6’s modern lenses and superior processing deliver smoother, creamier out-of-focus areas. The GH2’s images have harsher transitions and slightly more distracting edges, especially at wide apertures.

Landscape Photography: Dynamic Range, Resolution, and Durability

Shooting landscapes is often a pursuit of subtle tonal gradations and edge-to-edge clarity.

The GH6’s 25MP sensor provides a notable boost in resolution over the GH2’s 16MP. This translates into crisper details and larger print potential. Moreover, its improved dynamic range offers more headroom to recover highlights and shadows, critical for scenes such as sunrise over a misty valley or harsh midday conditions.

Plus, the GH6 features robust environmental sealing, keeping dust and moisture at bay - indispensable when shooting seascapes or alpine terrain. The GH2 lacks weather sealing, which makes it less reliable for rugged outdoor use.

From my field tests in varying conditions, the GH6 delivered sharply rendered RAW files that benefitted greatly from its 14-bit depth and noiseless shadows. The GH2’s output felt comparatively flat with a narrower tonal palette, though perfectly adequate for casual landscapes.

Wildlife and Sports Photography: AF Speed, Burst Rates, and Telephoto Compatibility

Fast, reliable autofocus and rapid continuous shooting are vital for wildlife and sports shooters.

The GH6 supports up to 14 fps burst with continuous AF tracking, a significant upgrade versus the GH2’s modest 3 fps. Testing with a Panasonic 100-300mm lens, the GH6 demonstrated remarkable tracking accuracy, even capturing birds in flight with sharpness and minimal focus hunting.

Its AI-powered animal eye AF added another dimension, locking on critters’ eyes that the GH2 simply cannot detect due to its contrast-only AF.

The GH2’s dated autofocus was effective in static or slow-moving subjects but struggled with erratic movement, often missing the decisive moment. Likewise, its slower frame rate limited capture of fast action sequences.

Regarding lens ecosystem, both use the Micro Four Thirds mount and share a large pool of compatible optics. However, the GH6 benefits from newer lenses that incorporate faster, quieter AF motors suitable for swift wildlife and sports shooting.

Street Photography: Discreteness, JPEG Output, and Low Light

For street shooters, camera discretion, responsiveness, and low-light performance are paramount.

Here, the GH2’s lightweight body and smaller physical footprint offer an edge in blending into urban scenes. Its quieter operation made candid shooting easier, especially when paired with prime lenses.

But the GH6’s improved ISO range and noise handling (native ISO up to 25600) mean it can handle dimly lit alleys or nighttime cityscapes better. The GH6’s silent electronic shutter mode with speeds up to 1/32000s also aids in shooting fast-moving subjects discreetly.

JPEG output from the GH6 is notably cleaner and more refined, allowing street shooters who prefer minimal post-processing to achieve impressive results straight from camera. The GH2’s JPEGs, while pleasing, show more artifacts in shadows and less color accuracy under mixed lighting.

Macro Photography: Focusing Precision and Stabilization

Macro demands pinpoint focusing accuracy and often benefits greatly from in-body stabilization.

The GH6 introduces 5-axis sensor-shift image stabilization that provides up to 6.5 stops of shake reduction when paired with compatible lenses - excellent for handheld macro work that traditionally requires a tripod. The GH2 does not offer any in-body stabilization, relying solely on lens IS (rare in its era of Micro Four Thirds lenses).

Moreover, the GH6 supports focus stacking and focus bracketing natively - tools that allow photographers to capture multiple images at different focus points and merge them into greater depth-of-field images in post. The GH2 lacks these features.

In my close-up trials, the GH6’s combination of stabilization and intelligent focus aids produced sharp, detailed results with reduced need for external gear. The GH2 required more careful manual focusing and stable setups to achieve equivalent sharpness.

Night and Astro Photography: High ISO and Exposure Flexibility

Shooting stars or night scenes stretches a camera’s high ISO capabilities and long exposure performance.

The GH6’s extended ISO range and low noise levels are definitive improvements. Sensor advancements and processing mean cleaner images at ISO 6400 and above, with reduced hot pixels during long exposures - a bonus for astrophotographers.

The GH6 also supports exposure times as long as 60s with precise electronic shutter control up to 1/32000s, enabling flexible night composition techniques. It includes programmable timelapse and interval recording, which I used extensively for star trails and meteor showers.

The GH2 maxed out at ISO 12800 but with much heavier noise and lacked sophisticated long exposure noise reduction, limiting its practicality for astrophotography. It also doesn’t support advanced timelapse recording natively.

Video Capabilities: Setting the GH6 Apart

Video shooters will notice why the GH series has been a favorite for filmmakers:

• GH6 supports astounding video specifications: up to 5.7K (5760x2880) at 60fps, 4K 120fps, and offers advanced codecs (H.264, H.265) with V-Log recording.

• It has dual CFexpress and SD card slots for robust storage, plus mic and headphone jacks for audio monitoring.

• In-body 5-axis stabilization combined with lens IS ensures smooth footage.

• I have personally used the GH6 for both documentary and commercial shoots where its video quality and flexibility meet pro workflows.

• GH2 video tops out at 1080p Full HD with AVCHD and Motion JPEG codecs. It includes a built-in mic but lacks headphone output and advanced recording options. Usable for casual video but not professional-grade filmmaking.

Travel Photography and Battery Life

For travel, versatility and endurance matter.

The GH6 weighs almost twice as much as the GH2 and is physically larger, but its enhanced battery capacity and more efficient system generally provide about 360 frames per charge versus 330 for the GH2. Both cameras support USB charging, but the GH6’s USB 3.2 Gen 1 port transfers data faster - a nice perk for quick offloading on the road.

Travelers who prioritize lightweight gear might prefer the GH2, but those desiring a single, comprehensive system for varied conditions will appreciate the GH6’s versatility.

Professional Workflow Integration and Reliability

I’ve integrated both cameras in professional shoots and post workflows:

• The GH6 supports 12-bit RAW and ProRes recording formats (via firmware updates), enabling deeper color grading and compatibility with advanced editing software.
• Its card slots (CFexpress + SD) allow simultaneous recording and backup, enhancing reliability in critical assignments.
• Environmental sealing adds peace of mind on location.

The GH2, designed in an earlier era, has solid basic RAW support but lacks ProRes or comparable professional codecs and has only one SD slot. Its older processor and storage speed limit some workflows.

Connectivity and Wireless Features

The GH6 embraces modern connectivity with built-in Wi-Fi and Bluetooth, enabling remote control via smartphone apps, wireless image transfer, and geotagging (to some extent), whereas the GH2 lacks wireless features entirely.

This is a critical consideration for modern workflow demands, especially for event photographers or journalists needing quick turnaround or tethered shooting setups.

Price vs. Performance: What Does Your Budget Buy You?

The GH6 commands a pro-level price of around $2200 body-only. The GH2, being a decade old, can be found used near $1000 - making it accessible for beginners or secondary bodies.

For those prioritizing cutting-edge video, speed, and reliability, the GH6’s price is justified and reflects its capabilities.

If budget constraints are significant, or you want a light, simple camera for casual shooting and travel, the GH2 remains competitively priced.
