In the rapidly evolving world of mirrorless cameras, Panasonic's Lumix GH-series holds a special place as a pioneer of hybrid photo-video performance in the Micro Four Thirds format. The Panasonic GH2 and GH4, though separated by a few years, represent powerful milestones in this lineage. As someone who has tested thousands of cameras over 15 years, including extensive hands-on with GH-series models, I’m excited to dig into this comparison.

Together, these cameras reveal the dramatic leaps in imaging technology from 2011's GH2 to 2014's GH4, spanning sensor improvements, autofocus refinement, video capability expansions, and ergonomics evolution. This article aims to give you THE practical insights you need - whether you’re choosing a budget-conscious advanced mirrorless or eyeing the prosumer-grade upgrade - across major photography disciplines and real-world use cases.

Let’s start by getting a feel for how these two physically compare on a practical level.

Size and Handling: Compact Workhorses, But Different Weights

Physically, both the GH2 and GH4 embrace that traditional SLR-style mirrorless design familiar to Panasonic’s Micro Four Thirds lineup. Measuring approximately 124x90x76mm (GH2) versus 133x93x84mm (GH4), the GH4 is noticeably bulkier and heavier - clocking in at 560g versus 442g with batteries.

While the GH2 is delightfully compact and responsive, well-suited for long handheld sessions or street photography, the GH4’s extra heft brings a reassuring solidity and balance, especially when paired with larger lenses. The marginal increase in grip size on the GH4 also helps with handling heavier telephotos without wrist fatigue, an advantage for wildlife and sports photographers.

Ergonomically, both feature a fully articulated 3-inch LCD, but we’ll get deeper into display and control differences later. Overall, this physical size gap reflects Panasonic’s shift toward professional robustness in the GH4 while retaining the GH2’s travel-friendly compactness.

Design and Controls: Intuitive Yet Evoluted User Interfaces

Next, let’s peek at the top control layout and design refinements that contribute directly to shooting efficiency.

The GH2 provides a straightforward control scheme with dedicated exposure mode dials, customizable function buttons, and direct access to key settings. However, the GH4’s layout introduces more buttons, a secondary control dial, and an updated articulation for streamlined operation.

Panasonic smartly embraced a more tactile experience on the GH4, which reduces menu diving during critical moments like sports or wildlife tracking. The addition of an illuminated focus mode switch and AF joystick on the GH4 further enhances precision during autofocus point selection - a feature missing on the GH2.

For videographers, the GH4 added convenient toggles for video settings, reflecting its pro-focused design. These refinements, while mostly subtle, mark a meaningful step in user experience.

Sensor and Image Quality: Foundation for Stunning Shots

Both cameras share a Four Thirds 17.3x13mm CMOS sensor with a 16MP resolution, but advances in sensor design and processing in the GH4 allow it to genuinely outperform the GH2 in several critical ways.

The GH2 uses Panasonic’s Venus Engine FHD processor, whereas the GH4 boasts the much more advanced Venus Engine IX. This leap significantly enhances noise control, dynamic range, and raw processing speed.

When tested under identical conditions, the GH4’s sensor extension to ISO 25,600 native gives it remarkable low-light versatility for a Micro Four Thirds sensor - outperforming the GH2's ceiling of ISO 12,800 by a wide margin. This difference manifests tangibly in cleaner shadows, richer details, and improved color depth (23.2 bits vs. 21.2 bits color depth on DxOMark scores).

Dynamic range testing further cements the GH4’s advantage, with 12.8 EV over the GH2's 11.3 EV measured at base ISO, allowing for better recovery in high-contrast landscapes or backlit portraits.

LCD and Viewfinder: Seeing is Believing, Right?

A photographer’s ability to compose and review images often hinges on display quality. Panasonic made significant strides moving from the GH2’s 460k-dot TFT LCD to the GH4’s crisp 1,036k-dot OLED screen.

The GH4’s OLED panel delivers richer blacks, stronger contrast, and wider viewing angles - fantastic for critical focusing or outdoor shooting with glare. Thanks to enhanced touchscreen capabilities, the GH4’s interface feels noticeably more responsive and intuitive.

The electronic viewfinder on the GH4 also takes a huge leap with 2,359k-dot resolution versus the GH2’s unspecified but considerably lower pixel count. The GH4’s EVF offers a brighter, more detailed view with excellent color fidelity and near-zero latency. This makes a huge difference in demanding situations like macro photography or fast-action tracking where precision is paramount.

Autofocus Performance: From Modest to Highly Competent

Autofocus systems define how well a camera locks onto subjects, especially critical for wildlife, sports, and street photography. The GH2’s 23 contrast-detection focus points were commendable in their 2011 context but modest by modern standards.

The GH4, meanwhile, packs 49 AF points with improved contrast detection and a much faster overall AF acquisition speed. It also introduces touchpad AF, allowing AF point selection by touching the rear LCD - a boost in ergonomics during quick compositions.

While neither camera offers phase-detection AF on sensor, which is becoming increasingly common, the GH4’s expanded coverage and refined algorithms elevate continuous autofocus tracking capabilities noticeably.

During shooting tests of moving subjects (bird flight, soccer matches), I found the GH4 able to track with more confidence and fewer hunting episodes compared to the GH2, where slower AF and fewer points sometimes led to missed shots, especially in low light.

Burst Shooting and Buffer: Fast Action vs Leisure

In burst shooting, the GH2 offers a modest 3fps continuous shooting rate, enough for casual action freezes but limiting for action or wildlife photographers who demand rapid frame sequences.

The GH4, however, excels at 12fps (in silent mode), allowing photographers to capture fleeting moments with precision. This burst rate, combined with larger buffer capacity, means significantly less dropped frames during prolonged rapid shooting.

This is a game changer for sports, wildlife, or any fast-paced environment where decisive timing is critical.

Weather Sealing and Build Quality: Ready for the Elements

While neither camera is fully weatherproof, the GH4 introduces partial environmental sealing, enhancing dust and splash resistance. The GH2 lacks any official weather sealing.

This feature adds invaluable peace of mind for landscape photographers or outdoor shooters operating in less controlled environments. Construction-wise, the GH4’s magnesium alloy chassis feels more rugged and premium, while the GH2 leans on polycarbonate and metal mix, offering moderate durability for the price.

Lens Ecosystem and Compatibility: A Shared Advantage

Both cameras use the Micro Four Thirds mount, opening access to a mature ecosystem of lenses from Panasonic, Olympus, and third parties, totaling over 100 varied optics.

This is a significant strength for both cameras, giving photographers flexibility to tailor setups for portraits, macro, wildlife telephotos, wide landscapes, or video optics at all price points.

The main difference is the GH4’s compatibility with newer lens features like Power OIS and some advanced OIS modes, enabling better stabilization synergy, though neither camera features in-body stabilization.

Battery Life and Storage Options: Shoot Longer, Store Better

The GH4 boasts a notable battery life improvement, rated at approximately 500 shots per charge versus the GH2’s 330, reflecting advancements in power management.

Both cameras rely on single SD card slots compatible with SD/SDHC/SDXC cards (UHS-I supported on GH4), but Panasonic added timelapse recording and USB tethering features in the GH4 - absent in the GH2.

Connectivity and Wireless Features: Modern Conveniences

The GH2 offers no built-in wireless connectivity, meaning no integrated Wi-Fi, NFC, or Bluetooth. The GH4 remedies this with built-in Wi-Fi for remote control, image transfer, and geotagging via smartphones (though no GPS on-board).

For workflow-oriented pros and travel shooters, these features are meaningful time savers.
