Panasonic Lumix DMC-G2 vs. GH1: A Deep Dive for Enthusiasts and Pros

When considering mirrorless cameras from Panasonic’s earlier days, two models stand out: the Lumix DMC-G2 and the Lumix DMC-GH1. Both hold an important place in the evolution of Micro Four Thirds systems with unique strengths and quirks. But which one truly fits your photography needs in today’s terms? Having tested these cameras extensively, I’ll guide you through everything you need to know - from sensor tech and ergonomics to real-world shooting scenarios - to help you make an informed decision.

First Impressions: Design, Size, and Handling

Both the G2 and GH1 adopt the classic SLR-style mirrorless form factor, but Panasonic’s refinements between launches reveal themselves in subtle yet impactful ways.

• GH1: Slightly more compact and lighter at 385g, with dimensions 124 x 90 x 45mm. The body feels sturdy yet lightweight, making it suitable for extended handheld use.
• G2: Heavier at 428g with a deeper grip (124 x 84 x 74mm), it offers a more substantial feel in hand, which some users find boosts handling confidence, especially paired with larger lenses.

Ergonomics and Controls

Comparing button layouts and top-plate controls reveals how Panasonic evolved the user experience:

• G2 adds touchscreen functionality, addressing a big usability gap on the GH1. This makes selecting focus points faster and more intuitive, a big plus for beginners and street shooters.
• GH1 favors physical buttons and dials, rewarding users who prefer tactile control without touching the screen.
• Both have fully articulated 3-inch screens at 460k-dot resolution, ideal for creative angles and video monitoring.

Having shot with both, I found the G2’s touchscreen a game-changer for quick focus adjustments and menu navigation, though the GH1’s physical controls feel more precise for manual tweaking during fast-paced shoots.

Sensor and Image Quality: The Heart of the Matter

Both cameras utilize 12MP Four Thirds CMOS sensors with similar native resolutions (4000 x 3000 pixels). However, there are nuanced differences with real-world impact.

What this means visually:

• GH1’s larger sensor footprint (Four Thirds vs. Micro Four Thirds sensor labeling difference aside) and older Venus Engine HD processor actually provide better dynamic range, color depth, and low-light capability. This translates to richer shadow detail and cleaner image quality at higher ISO settings.
• The G2 pushes its ISO range to 6400 natively but lacks the noise control refinements of the GH1, reflected in a lower overall DxOMark score.

In practical shooting, I found the GH1 delivers cleaner files in dim environments and smoother tonal gradations in landscape scenes - crucial for post-processing latitude. The G2 is adequate for daylight and moderate ISO settings but struggles with noise beyond ISO 1600.

Autofocus Systems: Speed and Accuracy

Autofocus performance is vital for capturing sharp subjects under varying conditions.

Both cameras employ contrast-detection autofocus, which, while accurate, is generally slower and less suited to tracking fast-moving subjects compared to today’s phase-detection systems.

• The G2’s touchscreen AF with face detection improves focusing on portraits and casual subjects, allowing you to tap to focus quickly. This feature is missing on the GH1.
• GH1 lacks face and eye-detection; its focusing relies on multi-area or single-point selection through buttons.
• Continuous AF performance is very similar, both supporting burst modes up to 3 fps.

In wildlife or sports shooting tests, both cameras struggled to lock quickly on erratic movements - expected for their generation. The GH1 was slightly more responsive in low light, likely due to better low-light AF sensitivity, but neither excels in high-speed autofocus tracking.

Build Quality and Weather Resistance

Neither camera offers environmental sealing. Both are constructed with quality polycarbonate and metal mounts, with:

• GH1 feeling slightly more robust overall despite its lighter weight.
• G2 has a somewhat chunkier grip for secure handling but bulkier dimensions.

Neither is dustproof or splash-resistant, so for outdoor landscape or wildlife use in inclement weather, handle with care or use protective covers.

Display and Viewfinding Experience

The fully articulating 3-inch LCD on both is a fantastic feature at their price points and release periods, enabling creative shoots at difficult angles.

• G2’s screen adds touchscreen sensitivity, enabling focus point selection, navigating menus, and even self-timer activation with intuitive taps.
• GH1 maintains the same resolution screen without touch, relying on physical buttons for settings.

Viewfinders differ:

• G2 sports a modest 1,440-dot EVF with 100% coverage, giving a relatively clear preview.
• GH1 includes an EVF with similar coverage but no specified resolution, generally considered less bright and less sharp than the G2’s.

For me, the G2’s improved EVF and touchscreen synergy make it easier to compose and review shots swiftly, a boon for those used to smartphone camera ergonomics.

Lens Ecosystem and Compatibility

Both models use the Micro Four Thirds mount, offering broad lens compatibility from Panasonic, Olympus, and third parties.

• Panasonic’s lens lineup boasts over 100 optics compatible with both, spanning wide-angle, telephoto, macro, and fast-aperture primes.
• The G2’s 2.1x crop factor (typical of Micro Four Thirds) and GH1’s 1.9x focal length multiplier (slightly confusing as given in specs, but effectively same mount and sensor crop) mean lenses render equivalently on either body.

Choosing either camera opens many creative possibilities, so lens availability should not constrain your decision. However, newer lenses may communicate better with the G2 due to firmware updates and updated autofocus algorithms.

Battery Life and Storage

Battery life differences are minor. The G2’s slightly improved stamina lets you stay on location longer before swapping batteries. Both cameras accept widely available SD cards, but the G2 adds SDXC support, allowing larger modern cards.

Video Capabilities: Which Camera Wins?

Video performance was a key selling point for Panasonic’s Lumix GH line, often attracting hybrid shooters.

Key takeaway:
The GH1 significantly outperforms the G2 for video recording, offering full 1080p HD at up to 60 fps compared to the G2’s 720p limit at 30 fps. It uses the more professional AVCHD codec, yielding higher quality footage.

For aspiring videographers, the GH1 is clearly the superior choice, especially for capturing smooth, detailed Full HD video with manual focusing and audio inputs.
