Panasonic GH5 II vs Panasonic G2: A Thorough Comparison for Today’s Photographer

Choosing the right camera can be overwhelming - especially when deciding between models from the same manufacturer but separated by more than a decade of technological leaps. Here, I’ve taken an in-depth look at the Panasonic Lumix DC-GH5 II, released in 2021, and the Panasonic Lumix DMC-G2 from 2010. Despite sharing the Micro Four Thirds mount, these cameras target very different users and photography needs.

Drawing on my extensive hands-on experience testing hundreds of mirrorless cameras across genres, I’ll guide you through a direct, no-nonsense comparison. You’ll learn how these two stack against each other in real-world use, technical merits, and value - empowering you to choose wisely whether you want solid entry-level flexibility or a pro-caliber workhorse.

Getting Started: A Physical and Ergonomics Overview

The GH5 II and G2 look similar at first glance - they’re both SLR-style Micro Four Thirds mirrorless cameras with fully articulated 3-inch screens. But that’s where the close resemblance ends.

Size & Weight: The GH5 II feels substantial at 727g but remains comfortable for long shoots, boasting robust metal construction and weather resistance. The G2, considerably lighter at 428g, is more compact and portable, friendly for travel or casual use. This size weight difference reflects the GH5 II’s professional-oriented build versus the G2’s beginner-friendly design.

Ergonomics & Handling: I appreciate the GH5 II’s large, well-placed grip and thoughtfully arranged controls that allow quick access without diving into menus. The G2’s grip is noticeably smaller and less molded for hand comfort, while the button layout is simpler but less intuitive for fast action. For photographers who frequently adjust settings on the fly, the GH5 II clearly has an edge.

Design Differences Up Close: Control Layout and User Interface

Let’s dive deeper into how the two cameras place their key controls and whether their interfaces feel modern.

The GH5 II sports dedicated dials for ISO, shutter speed, exposure compensation, and mode - all tactile and easy to reach. It also includes customizable buttons, enabling you to tailor the camera workflow. This level of control reflects a pro-oriented design philosophy.

The G2, being 11 years older, offers fewer physical controls - mode dial, exposure compensation, and basic function buttons, but lacks quick ISO or shutter speed dials. The touchscreen is present on both but the GH5 II’s is more responsive and versatile, supporting advanced menus and touch focus.

For photographers who value direct, swift control in dynamic situations - think events or wildlife - the GH5 II’s interface is far superior. Casual shooters will still find the G2’s setup user-friendly for learning basics.

Sensor and Image Quality: A Quantum Leap in Resolution and Performance

Sensor technology drives the heart of image quality. The GH5 II has a 20MP 4/3” CMOS sensor without an optical low-pass (anti-aliasing) filter, while the G2 features a 12MP 4/3” sensor with an AA filter.

Resolution & Detail: The GH5 II’s 20 megapixels translate into higher native resolution (5184x3888 pixels vs. the G2’s 4000x3000), providing more freedom for cropping without significant quality loss. The absence of an AA filter on the GH5 II results in crisper detail and reduced softness.

Dynamic Range: According to DxOMark’s tests, the GH5 II scores an impressive 13.1 EV dynamic range versus the G2’s 10.3 EV. This broader latitude captures more nuanced shadows and highlights, vital for landscapes or high-contrast scenes.

Color Depth: The GH5 II’s color depth is 23.7 bits compared to 21.2 bits on the G2, allowing richer tone gradations and smoother color transitions.

Low Light & ISO: The GH5 II effectively doubles the G2’s high ISO usability, with better noise control up to ISO 25600 compared to ISO 6400. I’ve personally shot in dim interiors and evening street scenes where the GH5 II’s improved noise performance yields cleaner, more usable images.

In summary, the GH5 II’s sensor benefits from a decade of Panasonic’s incremental improvements - resulting in better resolution, dynamic range, and low-light sensitivity. The G2 remains capable if you don’t need ultra-high resolution or shoot aggressively in low light.

Display and Viewfinder: Clarity and Flexibility Matter

Both cameras have fully articulated 3-inch LCDs, but image resolution and viewing experience vary widely.

• Screen Resolution: GH5 II packs 1.84 million dots, offering sharp, bright previews with excellent detail - great for precise focusing and composition. The G2’s 460k dot panel is comparatively grainy and dim, making it harder to check fine detail or exposure outdoors.

• Viewfinder: The GH5 II’s 3.68 million-dot electronic viewfinder (EVF) provides eye-level clarity with 0.76x magnification and 100% coverage. The G2’s EVF is much simpler with 1.44 million dots and a smaller 0.55x magnification. For me, the GH5 II’s EVF is a joy to use in bright sunlight or for manual focusing.

• Touchscreen and UI: Both have touch-enabled screens. The GH5 II supports touch shutter, AF point selection, and menu navigation. The G2’s touchscreen handles basic focus and shutter release but is less responsive.

The GH5 II’s display and EVF combination make composing, reviewing, and adjusting shots easier and more precise across all lighting conditions.

Autofocus Systems: Speed, Accuracy, and AI Enhancements

The GH5 II excels with a 225-point contrast-detection AF system combined with advanced algorithms including eye and animal detection. The G2 relies solely on contrast-detection with an unspecified number of focus points.

In practice, the GH5 II’s autofocus feels responsive and reliable even in low contrast or fast-moving subjects - ideal for wildlife or sports. Its eye detection works well to lock focus precisely on human or animal eyes, enhancing portrait sharpness. The G2’s AF is slower and less confident, especially in challenging conditions or action sequences.

Shutter and Burst Performance: Capturing the Moment

Shutter Range:

• GH5 II: Mechanical shutter speeds from 60s to 1/8000s; silent electronic shutter up to 1/16000s.
• G2: Mechanical shutter speeds from 60s to 1/4000s; no electronic shutter.

Continuous Shooting:

• GH5 II: Up to 12 fps with autofocus tracking.
• G2: Up to 3 fps, much slower.

For sports, wildlife, or fast-moving subjects, the GH5 II offers a significantly improved shooting experience, helping you capture decisive moments crisply and reliably.

Lens Ecosystem and Compatibility: A Shared Advantage

Both cameras use the Micro Four Thirds mount with virtually identical lens compatibility. The system offers a broad range of native lenses - over 100 Panasonic and Olympus options - including primes and zooms for portraits, landscapes, macro, and telephoto needs.

This shared mount provides flexibility to invest in quality optics, from affordable primes to pro-grade telephotos. The GH5 II gains an advantage from autofocus speed improvements that better utilize modern lenses’ capabilities.

Build Quality and Environmental Resistance: Toughness Versus Portability

The GH5 II is a weather-sealed, magnesium alloy body that resists dust and splashes, essential for demanding fieldwork in landscapes, wildlife, and event photography.

The G2 lacks environmental sealing and features a plastic build, which is lighter but less robust and less suited for tough conditions.

If you plan to shoot outdoors in variable environments, the GH5 II will be noticeably more reliable under adverse weather.

Battery Life and Storage: Ready for Extended Use

• Battery: The GH5 II uses the DMW-BLK22 battery rated for approximately 400 shots per charge; the G2’s battery is smaller at 360 shots. While similar, I found the GH5 II’s efficient power management and USB charging add convenience in the field.

• Storage: GH5 II supports dual UHS-II SD cards; the G2 has a single SD slot with UHS-I support only. Dual slots provide flexibility for backups or extended shooting sessions.

For travel or professional shoots, the GH5 II’s enhanced storage and power features add peace of mind.
