Panasonic GH2 vs Panasonic ZS30: An In-Depth Comparison for Photography Enthusiasts

Choosing the right camera is often less about pixel counts or specs on paper and more about matching the tool to your real-world needs and style. Sitting on opposite ends of Panasonic’s lineup, the Lumix GH2 and the Lumix ZS30 (aka TZ40) cater to very different photographers. The GH2 is a sturdy Micro Four Thirds mirrorless system camera, while the ZS30 is a compact travel-friendly superzoom. I’ve spent extensive time with both to give you a hands-on, honest comparison that highlights where each shines and where it stumbles - so you can decide which is the better fit.

From the Outside In: Build, Handling, and Controls

Ergonomics can make or break a camera’s usability, especially during long shoots. The GH2, with its SLR-style body, is significantly larger and heavier (442g vs. 198g for the ZS30), but this mass isn’t wasted. It provides heft and excellent balance with interchangeable lenses. The GH2’s grip is deep, and the button layout is classic Panasonic - functional without fuss. The fully articulating 3-inch LCD and an electronic viewfinder (EVF) round out a versatile handling experience for stills and video.

Contrast that with the ZS30, which is deliberately compact for travelers and street shooters prioritizing portability over full manual control. It lacks a viewfinder and relies solely on a fixed 3-inch touchscreen. Its buttons are small and squished, a typical compromise for pocketability. While it’s lighter on your shoulders for full-day travel, the slimmer body sacrifices some control agility.

Control-wise, the GH2 offers more dedicated dials for exposure compensation, shooting modes, and custom functions - clubs for your thumbs, if you will. The ZS30 packs exposure controls but prioritizes menu-driven adjustments and touchscreen input. For photographers who like to tweak settings on the fly, the GH2 is more immediately user-friendly.

Sensor & Image Quality: The Core Differences

Arguably the most defining difference is sensor size and resulting image quality:

With a sensor area almost 8x larger than the ZS30’s tiny 1/2.3-inch chip, the GH2 is miles ahead in image quality potential. Larger sensors capture more light and detail, which translates to better dynamic range and lower noise - especially critical for landscapes and portraits. Panasonic's Four Thirds sensor here ensures you get clean JPEGs and flexible RAW files.

The ZS30’s modest-sized sensor is closer to what you'd find in your average compact. It's fine for casual snapshots in good light, but struggles in low light or high-contrast scenes.

I put both through rigorous tests under varied lighting - indoor portraits, outdoor landscapes in harsh sun, and twilight street shoots. The GH2 consistently delivered richer colors, smoother gradations, and retained shadows and highlights better. Noise levels at ISO 1600 and above were notably higher on the ZS30, limiting its use in dim settings.

Autofocus & Speed: Keeping Up with the Action

For action photographers - whether wildlife, sports, or street - the autofocus system and burst speeds are key.

GH2 autofocus:

• 23 focus points with contrast detection
• Face detection enabled
• AF modes: Single, Continuous, Tracking, Selective, Live View AF
• Continuous shooting rate: 3 fps

ZS30 autofocus:

• 23 focus points, contrast detection
• AF modes include Center, Multi-area, Touch AF
• Continuous shooting rate: 10 fps (but limited buffer and slower write speed)

While the ZS30 boasts a higher burst speed on paper (10fps), the buffer depth is shallow, and image processing slows you down after a handful of shots. The GH2’s 3fps might sound sluggish, but it’s more sustained and coupled with sharper autofocus tracking. The GH2’s face detection and tracking remember subjects better under varied light and motion, which is essential for portrait and wildlife shooters.

Neither camera employs phase detection or advanced eye/animal eye AF, so very fast-moving subjects can occasionally frustrate.

Lens Systems & Flexibility: The GH2’s Big Advantage

A camera body is only as good as the lenses it can support. Here’s a crucial distinction:

• GH2: Micro Four Thirds mount. Over 100 lenses available from Panasonic, Olympus, and third parties - from ultra wide to super telephoto and dedicated macro.
• ZS30: Fixed 24-480mm equivalent zoom lens (F3.3-6.4 aperture).

The GH2 lets you customize your setup for nearly every photography genre. Need a bright f/1.7 portrait prime? Available. Want a weather-resistant telephoto for wildlife? Plenty on offer. Macro? You got it.

The ZS30 zoom lens range is impressively versatile, especially for travel and casual shooting, but aperture limitations (up to f/6.4 at tele end) restrict low light performance and bokeh quality. Sharpness also suffers compared to prime or high-end zoom lenses on the GH2.

Display & Viewfinder Experience

Both have 3-inch LCDs, but the GH2’s is fully articulating with 460k resolution and touchscreen, while the ZS30’s is fixed with a sharper 920k touchscreen.

The GH2’s EVF is another pivotal UX win, letting you frame in bright sunlight and compose steadily - vital for serious shooting.

The ZS30’s lack of a viewfinder means you might struggle with glare outdoors. The higher-resolution screen is crisp but can’t replace eye-level stability.

Battery Life & Storage

Practical considerations like battery life can sway your decision.

• GH2: Approx. 330 shots per charge
• ZS30: About 260 shots per charge

While both use proprietary lithium-ion packs, the GH2’s marginal advantage may matter on longer outings.

Each camera has one SD card slot, but the GH2 supports SDXC cards with faster write speeds, crucial for RAW and video.

Video Functionality: More Film Buffs Get Happy with the GH2

Panasonic’s GH series is renowned for video, and the GH2 is no exception.

Features:

• Full HD 1080p recording at 24/30/60fps in AVCHD and Motion JPEG
• External mic input (important)
• Fully articulating screen aids self-recording / Vlogging
• Manual exposure controls during video

The ZS30 shoots 1080p at 60fps too but lacks a mic input and only offers fixed lens convenience. Its optical stabilization helps smooth video, but image quality and control are inferior.

Usage Across Photography Genres

Let’s break down how these cameras really perform across the board:

Portrait Photography

The GH2’s larger sensor excels at smooth skin tones and shallow depth of field for flattering bokeh. Face detection AF helps keep eyes sharp. The ZS30 struggles here - you get busy backgrounds and noisier images, especially indoors.

Landscape Photography

Dynamic range and resolution matter. GH2 dominates with 11.3 EV dynamic range and 16 MP sensor. Weather sealing is absent on both but the GH2 can withstand more lens choices for rugged shooting.

Wildlife Photography

The GH2 paired with tele lenses is better for tracking animals. Its AF tracking is more dependable, and 3fps burst is usable. ZS30’s 20× zoom is handy for casual wildlife but image quality degrades at max zoom.

Sports Photography

Neither camera is a pro sports shooter (no pro-level FPS or phase AF). The GH2’s shooting modes are more suited for timed bursts in moderate lighting. The ZS30’s 10fps burst is shallow buffer-limited.

Street Photography

The ZS30 wins in portability and discretion. Its compact size and silent operation are a plus. GH2 is bulkier, less stealthy.

Macro Photography

GH2 with dedicated macro lenses offers superior focusing precision and magnification. ZS30’s macro mode (3cm minimum) is decent but image quality less crisp.

Night and Astro Photography

GH2’s low noise at high ISO gives it the edge for starry shots and long exposures. The ZS30’s tiny sensor produces noisy results past ISO 800.

Video

GH2 is a much stronger video platform for creators needing manual control, external audio, and versatility.

Travel Photography

ZS30 excels with its zoom lens, compact size, and built-in GPS tagging. GH2 needs a kit lens or zoom and more space - but delivers better image quality.

Professional Workflows

GH2’s RAW support, AVCHD video, and external mic input make it suitable as a secondary professional tool. ZS30 is purely consumer-level.
