The E-M10’s sensor delivers roughly 33% higher resolution and improved dynamic range and color depth compared to the GF2. Specifically, the extra stop-plus headroom in dynamic range manifests in better highlight retention and shadow detail, critical for landscape and high-contrast portrait work. The higher ISO ceiling of the E-M10 extends usability into more challenging low-light environments, producing cleaner images with less noise at elevated sensitivities.

In practical tests, the E-M10 produced richer tonality gradients and greater subject separation in natural light portraits. The GF2’s images tend to show a slight softness attributable to lower resolution and sensor noise starting to dominate above ISO 1600.

Display and Viewfinder Experience: Framing Precision and Usability

High-resolution electronic viewfinders and articulating LCDs enhance compositional accuracy and operational comfort.

• Olympus E-M10: Equipped with a 1.44 million-dot OLED electronic viewfinder offering 100% coverage and 0.58x magnification, this EVF is a significant advantage over the GF2. Coupled with a fully tilting 3” touchscreen LCD at 1.04 million dots, it enables precise framing handheld and from unconventional angles or low perspectives.

• Panasonic GF2: Lacks any viewfinder; the photographer must rely wholly on the 3” fixed basic touchscreen LCD at 460,000 dots. This hurts accuracy in bright sunlight and reduces framing flexibility. The screen’s lack of tilt capability limits shooting versatility, especially for macro or low-angle perspectives.

Testing confirms the E-M10’s interface allows faster and more confident subject tracking, framing, and menu navigation. The GF2’s screen limitations impair operation under dynamic scenarios or high-contrast conditions.

Autofocus System: Speed, Accuracy, and Tracking Capability

Autofocus defines a camera’s ability to capture sharp images, especially with moving subjects or in varying light.

Both cameras use contrast-detection autofocus, which typically results in slower acquisition than phase-detect systems. However, the Olympus E-M10’s 81 focus points allow finer focus area selection, better tracking precision, and responsiveness than the GF2’s 23 points.

In real-world trials, the E-M10 consistently acquires focus faster and tracks subjects more reliably. Its touch-to-focus interface on the LCD enhances usability in live view and video modes. The GF2, while capable under static conditions, struggles with moving subjects and low-contrast scenes due to fewer AF points and slower AF algorithms.

Notably, neither provides animal eye-detection AF, which limits effectiveness for wildlife applications, but face detection is accurate on both for portraits and event photography.

Burst Shooting and Shutter Performance: Capturing the Decisive Moment

Sequential shooting capabilities are vital for sports, wildlife, and fast-action photography.

The E-M10’s max 8 fps burst shooting outpaces the GF2’s modest 3 fps, enabling improved moment capture during sports or wildlife sequences. This rate, combined with reliable autofocus tracking, benefits event and action photographers.

Neither model features electronic shutter options or silent shooting, which limits silent capture capabilities but simplifies exposure control and flash sync compatibility.

Image Stabilization: Sensors That Hold Steady

In-body image stabilization (IBIS) is crucial for handheld shooting, particularly at slower shutter speeds and with non-stabilized lenses.

• The Olympus E-M10 features 3-axis sensor-based stabilization, rated to compensate for roughly 3 stops of camera shake. This effectively extends handheld low-light usability and improves video stability without reliance on lens stabilization.

• The Panasonic GF2 lacks in-body stabilization, requiring lenses with optical stabilization for shake compensation. This reduces system-wide versatility and can cause limitations in low-light and telephoto shooting.

Practical testing confirmed the Olympus’s IBIS delivers noticeable benefits in stabilizing handheld shots at shutter speeds as low as 1/15 sec, especially for macro and low-light handheld scenarios. The GF2 shows more motion blur unless combined with optically stabilized lenses, which adds cost and bulk.

Flash and Low-Light Performance: Illumination Options and ISO Handling

Each camera incorporates an internal pop-up flash and supports external flash units.

The flash guide numbers are similar, though the Olympus’s faster max sync speed offers greater flexibility in fill-flash and high-speed sync shooting scenarios. The E-M10’s superior noise handling at elevated ISOs makes it more reliable for night and event photography.

Video Capabilities: Resolution, Frame Rates, and Usability

Video functionality has become a core consideration for hybrid photographers.

• The Panasonic GF2 supports Full HD 1080p recording at 60fps, enabling smooth motion capture and slow-motion interpolation, as well as multiple lower resolutions and frame rates. It encodes in AVCHD and Motion JPEG formats.

• The Olympus E-M10 records Full HD 1080p, but limited to 30fps. Video encoding is via H.264 and Motion JPEG. The E-M10’s in-body stabilization aids handheld video smoothness despite lacking advanced video features such as headphone/mic jacks.

Neither camera offers 4K or high-bitrate video codecs. The GF2’s higher frame rate options appeal more to videographers seeking smoother motion, though limited by no external audio input options.

Battery Life and Storage: Power and Capacity

• Olympus E-M10 uses the BLS-5 battery rated for approximately 320 shots per charge under CIPA testing standards.

• Panasonic GF2 offers a slightly lower battery life of around 300 shots per charge.

Both rely on a single SD, SDHC, or SDXC card slot. For extended usage scenarios such as travel or professional shoots, the E-M10 provides marginally longer operation, but neither model is exceptional in battery endurance by modern standards.

Lens Ecosystem Compatibility: Creative Flexibility

The shared Micro Four Thirds mount environment provides access to an extensive array of over 100 lenses from multiple manufacturers, including Olympus, Panasonic, Sigma, and others.

• The Panasonic GF2 benefits from the full breadth of modern stabilized lenses, which mitigate its lack of IBIS.
