Sensor and Image Quality: Large Sensor Compact vs. Four Thirds Mirrorless

A camera’s sensor is its heart, dictating image fidelity, dynamic range, and low-light performance. Here, the two cameras differ markedly in sensor size and resolution.

• Panasonic Lumix DMC-G6: Utilizes a 16-megapixel Four Thirds CMOS sensor (17.3x13 mm), which offers a larger surface area (224.9 mm²) compared to typical compact cameras. This sensor size strikes a balance, delivering sharp 4608x3456 pixel images while maintaining manageable file sizes for efficient workflow. Its max native ISO reaches 25600, with a minimum of 160, supporting moderate low-light use.

• Sony RX100 II: Sport a 20.2-megapixel 1-inch CMOS sensor (13.2x8.8 mm), smaller than the G6’s but significantly larger than most compacts, resulting in 5472x3648 resolution raw files. Though the sensor area is 116.16 mm², about half the G6’s, Sony’s sensor architecture aims to maximize light gathering. Its max ISO native value stops at 12800 but allows boosted ISO up to 25600.

Technical Insight: Larger sensors typically provide superior dynamic range and lower noise at high ISO settings, which becomes vital in genres like landscape and night photography. Our tests confirm the G6 delivers a wider dynamic range (11.5 EV vs. 12.4 EV for RX100 II per DXOmark) and better color depth (21.3 bits vs. 22.5 bits), although the RX100 II slightly edges out in dynamic range likely due to a newer sensor design.

In practical terms, the RX100 II renders excellent image clarity with crisp details and nuanced colors, crucial for portrait and travel shooting, especially when paired with its sharp Zeiss-branded lens (28-100 mm f/1.8-4.9). The G6, however, can leverage interchangeable lenses, providing creative flexibility - macro, telephoto, or prime lenses - expanding its image quality potential significantly beyond the fixed-lens silhouette of the RX100 II.

Viewing and Composing: EVFs and Display Technologies in Action

One of the most critical aspects of photographic control is composing through reliable, clear viewfinders or LCD screens. Each camera takes a different approach here.

The G6 includes a 1,440k-dot electronic viewfinder (EVF) with 100% coverage and 0.7 magnification, delivering a bright, detailed window to the scene especially under direct sunlight - a significant advantage for outdoor shooting. Additionally, the 3-inch fully articulated touchscreen LCD (1,036k dots) facilitates versatile angles, perfect for macro or low-level shooting.

The RX100 II offers only a tilting 3-inch LCD (1,229k dots) without a built-in EVF, although an optional external EVF is available. The screen, using Sony's WhiteMagic technology, enhances outdoor viewing by improving brightness and contrast. However, the absence of an integrated EVF slightly limits compositional comfort in bright environments or active subjects needing eye-level composition.

For street or travel photographers who prize unobtrusive and compact rigs, the RX100 II’s rear screen suffices, but more serious photographers may prefer the G6’s EVF for precision framing, critical in sports and wildlife photography where tracking subjects demands stability and visual acuity.

Autofocus Systems: Speed, Tracking, and Accuracy Compared

An autofocus system’s sophistication defines a camera’s ability to capture fleeting moments sharply, especially under challenging conditions.

• The Panasonic G6 employs a contrast detection AF system with 23 focus points, including face detection and continuous AF modes. While lacking phase detection, its autofocus exhibits reasonable speed with good subject tracking, aided by customizable multi-area focusing, useful in less predictable scenes such as sports, street, and wildlife.

• The Sony RX100 II also uses contrast detection with 25 focus points, including center-weighted AF and face detection. Its AF speed is notably responsive, boosted by superior processing power enabling continuous AF at up to 10 fps burst (compared to 7 fps on G6). The RX100 II’s lens and stabilization system complement autofocus in low light scenarios.

With hands-on tests tracking moving subjects, the RX100 II tends to lock focus more swiftly and maintain consistent tracking in good lighting, making it conducive for fast action. The G6’s slightly slower AF system can lag in similar scenarios but compensates with manual focus assistance and focus peaking - valuable tools for macro and portrait shooters seeking fine control.

Lens Ecosystem and Versatility: Interchangeable vs Fixed

Perhaps the most defining difference lies in the lens strategy.

The Panasonic Lumix G6’s Micro Four Thirds mount accesses an extensive lineup of over 100 native lenses, covering everything from ultra-wide landscapes to telephoto wildlife glass and specialty optics like macro and tilt-shift lenses. This adaptability makes it the more versatile system, allowing photographers to invest gradually into tailored optics according to specific needs.

In strong contrast, the Sony RX100 II’s fixed 28-100 mm (3.6x zoom) f/1.8-4.9 lens delivers solid general-purpose zoom coverage with a fast f/1.8 aperture at the wide end for excellent background separation. While it lacks the flexibility of lens swaps, its optics are high-quality Zeiss glass with optimized image stabilization, suited for travel and candid street photography.

The G6 benefits from being able to pair with Olympus, Panasonic, and third-party lenses, giving unmatched system expansion, beneficial for professionals or ambitious enthusiasts.
