My review draws on extensive real-world testing, technical rigor, and practical use-case scenarios tailored to photographers ranging from beginners to seasoned professionals.

Let’s explore how these two devices stack up across a broad spectrum of criteria and photographic disciplines.

Physical Design and Ergonomics: Bridging Versatility with Portability

Starting with the form factor, the Panasonic FZ70 adopts a traditional bridge camera silhouette - bulky but ergonomic with a prominently positioned grip and intuitive button layout. The GF1, by contrast, embraces a compact, rangefinder-style mirrorless design, emphasizing portability and discretion.

The FZ70’s dimensions (130 x 97 x 118 mm) and weight (606g) reflect its ambitious 60x zoom lens system. This size demands a more deliberate shooting setup, favoring users who prioritize reach and versatility over pocketability. Meanwhile, the GF1’s compact body (119 x 71 x 36 mm) and lightweight 385g build enable comfortable handheld shooting and easy transport - ideal for street, travel, and candid photography.

Holding the FZ70, one notices the deep grip and solid plastic construction that balances substantial lens mass. The GF1, though diminutive, offers a satisfying tactile experience through its metallic finish and minimalistic controls. However, the absence of a built-in viewfinder in the GF1 means reliance on the rear LCD for composition, which may affect outdoor usability.

Examining the top panel layouts, the FZ70 includes a robust dial for exposure compensation and mode selection, alongside dedicated buttons for ISO and effects - a boon for quick adjustments during active shooting. The GF1 keeps the control scheme minimal, with a mode dial and function button, reflecting its entry-level mirrorless status.

Overall, the choice here boils down to preference: a heavier, feature-rich bridge body versus a compact, modular system camera.

Sensor Technology and Image Quality: The Heart of the Matter

Arguably, the most fundamental difference lies in the sensor architecture - affecting image quality, dynamic range, and low-light performance.

The FZ70 employs a 1/2.3" CMOS sensor measuring 6.17 x 4.55 mm, covering a surface area of approximately 28 mm², and houses 16 megapixels. Conversely, the GF1 integrates a substantially larger Four Thirds sensor of 17.3 x 13 mm, yielding a sensor area close to 225 mm², but with 12 megapixels.

This size advantage for the GF1 is critical. Larger sensors can capture more light, which translates to improved image quality, higher dynamic range, and superior high-ISO performance. The FZ70’s smaller sensor, while capable of capturing decent images in good lighting, exhibits more aggressive noise at elevated ISO settings, affecting clarity especially in shadow detail.

According to DxOMark testing, the GF1 achieves an overall score of 54, with a color depth of 21.2 bits and a dynamic range of 10.3 EVs, outperforming the FZ70, which scores 41 overall, with color depth at 19.4 bits and dynamic range slightly higher at 10.8 EVs, although this is influenced by specific measurement parameters.

Low-light sensitivity is where the GF1 clearly excels: its measured low-light ISO is 513 compared to the FZ70’s 171, confirming the former's stronger performance in noise control and image fidelity in darker environments.

For photographers who prioritize pixel-level detail, the difference in sensor area and resulting image quality is a paramount factor when deciding between these models.

Autofocus Systems: Precision vs. Versatility

The autofocus (AF) system is crucial for capturing sharp images, particularly when shooting fast-moving subjects or working in challenging conditions.

Both cameras employ contrast-detection AF systems but significantly differ in AF area flexibility and speed.

The FZ70 features 23 AF points (specific cross-type points unknown), with face detection and continuous AF tracking capabilities. Its autofocus excels in stationary and moderately dynamic contexts thanks to optimized algorithms, though it struggles in low light and with fast autofocus acquisition compared to modern systems. Notably, it offers no animal eye-detection or phase-detection AF technology.

In contrast, the GF1 also offers 23 contrast-detection AF points but adds the ability for selective focus area selection and performs AF tracking in live view - a critical advantage for videographers and portrait shooters. Additionally, it supports face detection. However, without an electronic viewfinder or phase-detection AF, both cameras exhibit some hunting under dim conditions.

While neither camera is tailored for professional sports or wildlife photography requiring blazing-fast autofocus, the FZ70’s continuous AF and slower servo performance limit its effectiveness for fast action. The GF1’s more manual approach, coupled with manual-focus-friendly lenses, appeals to users emphasizing precision and creative control.

Lens Ecosystem and Optical Versatility

A defining feature separating these models is lens compatibility and ultimate photographic adaptability.

Panasonic Lumix FZ70: Fixed Superzoom Magnification

The FZ70 integrates a fixed 60x optical zoom lens with a focal length equivalent to 20–1200 mm. This immense range caters to photographers seeking ultimate reach without changing lenses, perfect for wildlife, sports, and travel scenarios where compactness must be balanced with telephoto capability.

The lens’ maximum apertures range from f/2.8 at wide-angle to f/5.9 at telephoto, which, while relatively bright at the short end, gradually narrows, potentially impacting low-light telephoto shooting. Macro focusing allows for close work down to 1 cm, a rare feat for superzoom bridge cameras. The optical image stabilization inherently smooths handshakes, improving handheld usability at long focal lengths.

Panasonic Lumix GF1: Interchangeable Four Thirds Lenses

Conversely, the GF1 accepts any lens from the Micro Four Thirds mount - hundreds available from Panasonic, Olympus, and third-party manufacturers. This system supports a broad array of primes, fast zooms, specialized macro lenses, and even high-performance telephoto optics.

While the GF1 body lacks optical image stabilization (OIS), many Micro Four Thirds lenses compensate with built-in stabilization, granting sharp results in versatile scenarios.

Filters, wide apertures (f/1.2–f/2.8), and specific macro or specialty lenses open up expansive creative possibilities unavailable on a fixed-lens bridge camera.

Thus, for photographers valuing modularity and optical quality, the GF1’s ecosystem presents a compelling advantage, albeit at higher cost and complexity - requiring investment in lenses to fully unlock the system’s potential.

User Interface and Rear LCD Screens: Composition and Review Experience

Both the FZ70 and GF1 feature a 3-inch fixed TFT LCD with identical resolution of 460k dots, but their usability diverges based on viewing angles and on-screen menus.

The GF1’s wide-viewing angle LCD employs TFT color technology designed for clearer outdoor visibility, crucial when composing without an electronic viewfinder (EVF). Its touchscreen absence limits intuitive finger-based control, but tactile buttons and dials make up via fast manual adjustments.

The FZ70 includes a lower-resolution 202k-dot electronic viewfinder, serving those who prefer eye-level composition. While not the most detailed EVF on the market, it adds significant value outdoors where LCD glare hinders framing. The rear LCD, although fixed and similar in resolution, shows narrower viewing angles and less brightness, which can frustrate certain shooting scenarios.

Menu systems lean heavily on Panasonic’s Venus Engine usability model - with quick access modes, but the FZ70 has more on-body controls explicitly mapped to common shooting parameters, aiding speed and efficiency in dynamic environments.

For photographers who prioritize precise composition and critical image review, the GF1’s superior LCD visibility outweighs its lack of EVF, whereas the FZ70’s EVF adds flexibility at some cost in screen clarity.
