Panasonic FP3 vs. Panasonic GH4: A Deep Dive into Two Eras of Photography Innovation

When comparing cameras from two quite distinct generations and product categories, it’s tempting to get lost in specs alone. But if you - like me - care most about real-world use, image quality, system versatility, and how these cameras serve different photographic ambitions, then the Panasonic Lumix DMC-FP3 and the Lumix DMC-GH4 represent a fascinating study in contrasts. These are cameras designed for radically different photographers, yet both carry the Panasonic name and a unique heritage.

After extensive hands-on testing and comparison across disciplines, shooting conditions, and practical workflows, I’ll walk you through the core distinctions, the practical trade-offs, and who really wins in each aspect of performance and usability. Whether you’re a casual snapshot enthusiast curious about ultracompact portability, or a pro-level shooter requiring serious power under the hood, this breakdown has plenty of insights.

A Tale of Two Cameras: Context and Design Philosophy

The Panasonic FP3, introduced in early 2010, falls comfortably into the ultracompact category. It’s a pocket-friendly fixed-lens camera with a simple interface - aimed squarely at casual photographers wanting grab-and-go convenience. The GH4, on the other hand, launched four years later and is a professional-grade Micro Four Thirds mirrorless camera. It’s geared toward serious enthusiasts and pros with demanding photo and video workflows.

Let’s start with a visual and size context. Look at the stark difference in physical proportions.

The FP3’s dimensions (99 x 59 x 19 mm) and lightweight 155g body make it nearly invisibly portable in a jacket pocket. The GH4 (133 x 93 x 84 mm, 560g) commands a solid grip and presence, resembling a small DSLR. One is about discreetness and simplicity, the other about control, durability, and handling.

This fundamental design divergence sets the stage for everything else - from controls to image quality to lens options.

Layout and Controls: Minimalist Simplicity vs. Professional Ergonomics

Moving from size to user interface, it’s immediately obvious the GH4 is made to be handled intensively.

The FP3’s top plate is sparsely populated, reflecting its limited manual override capability - no manual exposure modes or shutter/aperture priority. You get a fixed zoom lens, and autofocus is contrast-detection only, with limited focus points. The touchscreen is small and not the most responsive, further underscoring its casual use case. There is no viewfinder, and the screen resolution is modest at just 230k dots.

Conversely, the GH4 features a richly appointed control layout: multiple dials for ISO, exposure compensation, shutter speed, and aperture. Its fully articulated OLED touchscreen (1036k dots) complements a crisp, bright electronic viewfinder with 100% coverage and a 0.67x magnification. This setup encourages precise framing and dedicated shooting techniques - critical for professionals working under variable lighting and motion conditions.

This difference is not just cosmetic. It reflects two philosophies:

• FP3: Point-and-shoot simplicity with a fixed lens and limited manual input.
• GH4: A professional tool offering fine-grain control and substantial customization.

Sensor Size and Image Quality: From Compact Snapshots to True Mirrorless Detail

Arguably, the sensor is the beating heart of a camera - and here the chasm widens significantly.

The FP3 sports a 1/2.3" CCD sensor measuring 6.08 x 4.56 mm with 14MP resolution, targeting snapshots. The GH4 houses a larger Four Thirds CMOS sensor (17.3 x 13 mm) with 16MP resolution - widely respected for its balance of image quality, size, and video abilities.

From my lab testing and shooting experience, this translates to:

• Dynamic Range: The GH4’s sensor produces significantly wider dynamic range (approx. 12.8 stops DxO mark) than the FP3’s modest sensor, which struggles to retain details in shadows and highlights under high contrast.

• Low Light Performance: The GH4 offers high usable ISO sensitivity up to 25600 native (ISO 200–25600 range) with less noise and better color retention than the FP3’s maximum 6400 ISO native rating, which unfortunately comes with noise and detail degradation at higher settings.

• Color Depth and Tonality: The CMOS sensor’s handling of color gradations and subtle hues edges out the FP3’s CCD sensor, at least in all but the brightest, well-lit daylight scenes.

In plain terms: the FP3 will do well in bright outdoor conditions but won’t cut it for demanding portraits, landscapes with shadow detail, or low light shooting. The GH4 produces technically superior images that respond elegantly to post-processing.

The Display and Viewfinder: Composing with Confidence

Let’s revisit the user experience with framing and reviewing images.

The FP3’s fixed 3" LCD screen at 230k resolution is only adequate on bright days and less forgiving in detail or menu navigation. The GH4’s 3" fully articulating OLED touchscreen, however, reveals fine details, vibrant colors, and smooth menu transitions. It becomes a creative asset for complex angles (macro shooting, low or high perspective), video monitoring, and reviewing images critically before leaving a location.

The big no-show on the FP3 is any kind of viewfinder. This means shooting inevitably requires looking at the LCD screen - more challenging in sunlight and less stable than eye-level framing.

The GH4 offers both a bright electronic viewfinder (EVF) and the high-res articulating screen, adding flexibility critical for precise manual focus efforts and fast action shooting.

Autofocus Systems: Tracking and Accuracy for Fast Paced Versus Casual Snapping

A thorough autofocus evaluation shines a spotlight on performance differences beyond sheer sensor size.

• The FP3 uses contrast-detection AF only, boasting 9 focus points but no face or eye tracking. It performs decently in good light but quickly slows down and hunts in dim or complex scenes, with no continuous autofocus or tracking once locked.

• The GH4 embeds contrast-detection autofocus with 49 points, but intelligently aggregates face detection, eye detection, and continuous AF modes, enabling smooth tracking for video and stills alike. During wildlife and sports shooting tests, its AF reliability and speed outmatched the FP3 considerably.

This means the FP3 is acceptable for still-life or casual street shooting where speed isn’t critical. The GH4 excels anywhere you need precision - portraits with accurate eye focus, runners on a track, bird-in-flight sequences, or video focus pulls.

Lens Ecosystem: Fixed Convenience Versus Expansive Creative Freedom

One of the biggest practical considerations between these two Panasonic models is their approach to optics.

• The FP3 is fixed lens only with a 35–140mm (35mm equivalent) zoom range at modest apertures (f/3.5–5.9). It’s convenient but compromises in low-light and creative depth-of-field control. Macro shooting is limited to 10 cm focusing distance, restricting fine close-up work.

• The GH4 benefits from the extensive Micro Four Thirds mount lens system - over 100 lenses, including fast primes, high quality zooms, macro, and specialty optics - offering immense creative flexibility. You can mount lenses with apertures as wide as f/1.2, or use telephoto superzooms for wildlife, or dedicated macro glass with focus stacking.

In my testing, the lens versatility of the GH4 was transformative, enabling photographers to match gear to genre perfectly. From landscapes requiring edge-to-edge sharpness to portraits with creamy bokeh, this system is a major asset over the FP3 platform.

Build Quality and Durability: Everyday Casual Versus Professional Weather Sealing

Here, the GH4 demonstrates its professional credentials with a rugged chassis and weather sealing (dust and splash resistant), suited for demanding environments. It’s noticeably heavier and feels rock solid in the hand under prolonged use.

The FP3’s plastic body and absence of sealing make it more vulnerable to knocks and weather. Given its ultracompact target, it’s best suited to casual indoor and fair weather shooting scenarios.

Burst Rates and Shutter Speed: Who Wins the Action Game?

Action photographers prioritize high frame rates and fast shutter capabilities.

• FP3 limits shutters between 1/60s and 1/1600s, with a slow burst up to 5 fps, and no continuous AF burst mode.

• GH4 extends shutter speeds from 1/60s to 1/8000s and achieves 12 fps continuous shooting with AF tracking.

These facts render the FP3 unsuitable for fast sports or wildlife sequences. For anyone interested in capturing fleeting moments, the GH4 is a far more capable machine. Coupled with the superior AF and larger buffer for raw files, the GH4 lets you harvest critical moments with confidence.

Video Capabilities: Casual Clips Versus Pro-Grade Filmmaking

The FP3 records basic HD video (1280 x 720 @ 30fps) in Motion JPEG format, adequate for occasional clips but limited in detail, bitrate, and professional utility.

The GH4 gained industry praise upon release for introducing 4K video recording (up to DCI 4K 24p), multiple frame rates up to 60 fps in HD, full manual exposure during video, and a microphone/headphone port for audio monitoring - features nearly unheard of in consumer cameras at the time.

This makes the GH4 a powerful hybrid device serving both pro videographers and multimedia content creators. In practical terms, the GH4 handles everything from documentary work to time-lapse, while the FP3 remains a casual video snapshotter.

Battery Life and Storage: Longevity and Workflow Considerations

Battery life is critical in fieldwork.

• GH4 impresses with approximately 500 shots per charge using the DMW-BLF19 battery, plus storage on SD/SDHC/SDXC cards with large capacities and fast write speeds - important when shooting raw bursts or 4K video.

• The FP3’s battery life figures are undocumented, but ultracompacts from this era generally last for fewer shots per charge and rely on smaller internal or proprietary batteries with limited capacity.

If you plan long shoots or travel, the GH4’s endurance and professional-grade batteries are a significant advantage.

Connectivity and Extras: Modern Conveniences and Workflow Integration

Built-in wireless connectivity is present only on the GH4, simplifying image transfer and remote control. The FP3 lacks any form of wireless communication and HDMI output, impeding modern workflow integration.

The GH4’s USB 2.0, HDMI, microphone and headphone jacks expand its utility.

Image Samples Comparison: Seeing is Believing

While technical specs tell much of the story, evaluating sample images seals understanding. Here’s a gallery featuring stills captured by both cameras under various conditions:
