Despite sharing the same MFT lens mount, the two cameras serve very different target users and eras of innovation.

Drawing from our extensive experience testing over thousands of cameras, we’ll examine these cameras across all major photographic disciplines, technical specs, and everyday shooting scenarios. Our goal is to empower you with clear, expert insight that helps you find your ideal creative companion.

At a Glance: Olympus E-M1 II and Panasonic G2 Specs in Side-By-Side

Handling and Build: A Tale of Two Designs

Starting with how each camera feels when held and operated: the Olympus E-M1 II follows Olympus’ trend toward a robust, weather-sealed, DSLR-styled body designed for professional use. Its magnesium alloy frame and thoughtfully placed grip offers excellent stability especially with longer lenses. The camera’s 574g weight balances portability and solid presence - important if you rely on confidence in rough environments.

In contrast, the Panasonic G2 is distinctly lighter and more compact (428g). Designed as a gentle entry point into mirrorless photography, its plastic construction and modest size help beginners get started without intimidation. The button layout is straightforward but lacks the tactile refinement and instant-access controls of the E-M1 II.

Ergonomically, the Olympus has more customizable buttons and dials for swift parameter changes. The G2 relies mostly on menus and touch control, which, while intuitive for novices, may frustrate users needing fast manual control under pressure.

Sensor and Image Quality: Crunching the Numbers with DXOMark Scores

The heart of image quality is the sensor, coupled with image processing engines:

• Olympus E-M1 II: 20 megapixels, no anti-aliasing filter for sharper images, paired with the TruePic VIII processor.
• Panasonic G2: 12 megapixels with an AA filter, powered by the older Venus Engine HD II.

DXOMark scores reveal a substantial quality advantage for Olympus:

The Olympus sensor’s higher resolution and cleaner signal at high ISO (with rating over ISO 1300) allow it to hold detail in shadows and deliver richer, more nuanced colors. Panasonic falls short in low-light scenarios, showing higher noise at ISO above 800.

Screen and Viewfinder: Your Window into the Scene

Both cameras sport fully articulating 3-inch monitors, but their usability differs:

• Olympus E-M1 II screen: 1.04 million dots with touchscreen functionality delivers sharp framing and intuitive focus selection. The bright display holds up well in daylight.
• Panasonic G2 screen: 460K dots, still with touch, but noticeably less sharp and contrasty, making it harder to confirm fine focus outdoors.

Electronic viewfinders (EVFs) are also a contrast point:

• Olympus offers a high-res 2.36 million-dot EVF with 100% coverage and 0.74x magnification. This means clearer, more immersive framing - valuable in bright light and fast action.
• Panasonic’s EVF is lower resolution (1.44 million dots) and smaller magnification (0.55x), offering a less detailed preview.

Practically, these factors translate to the Olympus giving you greater confidence in composition and focus, especially in challenging lighting and action scenarios.

Autofocus and Shooting Performance: Fast and Reliable vs Adequate

Autofocus System

• Olympus E-M1 II uses a blend of 121-point hybrid autofocus incorporating phase-detect and contrast-detect AF, enabling quick, accurate tracking and face/eye detection. This system works well with moving subjects in wildlife and sports environments.
• Panasonic G2 relies purely on contrast-detection AF with fewer focus points and no PDAF, resulting in slower lock-on and less reliable tracking for fast-moving targets.

Continuous Shooting

• Olympus’s staggering 60 fps full-resolution burst with electronic shutter (mechanical at 15 fps) is ideal for capturing fleeting moments in action and wildlife photography.
• Panasonic limits you to a mere 3 fps burst speed - fine for casual shooting but frustrating when timing is crucial.

The Olympus also features advanced focus bracketing and focus stacking options, providing versatility for macro and landscape photographers who demand precision.

Versatility Across Photography Genres

Let's explore real-world suitability of each camera for various photography types.

Portraiture

Olympus’s higher resolution, superior dynamic range, and 5-axis image stabilization combined with fast, accurate eye-detection autofocus enable clean, beautifully detailed portraits with smooth skin tones and creamy background bokeh - though the smaller MFT sensor means background blur is subtler than APS-C or full-frame.

Panasonic G2, with lower resolution and older AF, produces decent portraits but may fall short for professional work demanding refined detail and consistent focus on eyes.

Landscape

Here, the Olympus again shines because of:

• Higher dynamic range for capturing shadow and highlight detail across vast scenes
• Weather sealing that lets you shoot in unpredictable outdoor environments
• Robust focus bracketing for extended depth-of-field images

The Panasonic G2’s lower dynamic range and lack of sealing limits outdoor reliability but remains capable for casual landscapes.

Wildlife and Sports

Quick autofocus, high burst rates, and rugged build make the Olympus a clear choice. Its continuous 15 fps mechanical shutter speed and 60 fps electronic shooting excel at freezing movement - complemented by excellent lens compatibility, especially for telephoto optics.

Panasonic’s slower focus and low burst rate limit usability in fast-action sports or wildlife, better suited for posed or slower subjects.

Street Photography

Panasonic’s smaller, lighter body offers discreet handling better suited for unobtrusive street shooting. Though not as fast as Olympus, the G2’s touch screen and articulated LCD allow creative shooting angles.

Olympus is bigger and more aggressive in design, but still manageable. Its superior high-ISO performance helps when shooting in available light on city streets after dark.

Macro Photography

Olympus supports focus stacking and bracketing. Its sensor-shift image stabilization allows sharper handheld macro shots - crucial given close focusing distances. Panasonic G2 lacks these features, requiring more manual patience.

Night and Astrophotography

The Olympus outperforms Panasonic in high ISO noise control and dynamic range - both critical when shooting stars or nightscapes. It also supports long exposures and timelapse recording built-in, while the Panasonic does not.

Video Capabilities

Olympus recorded 4K UHD (up to 4096x2160 @ 24p) with clean H.264 codec, mic and headphone input for monitoring audio during shoots - a boon for serious videographers.

Panasonic G2 maxes out at 720p HD, with older AVCHD Lite codec. It has a mic input but lacks headphone jack or 4K support, limiting professional video use.

Lens Ecosystem and Compatibility

Both cameras share the Micro Four Thirds mount with an enviable catalog of over 100 lens options from Olympus, Panasonic, and third-party brands.

• The Olympus E-M1 II benefits from Olympus’s PRO series lenses, designed for durability and optical excellence, plus Panasonic’s excellent lenses for versatility.
• Panasonic G2 supports the same lineup but with older firmware may not exploit newer lens autofocus capabilities fully.

If you’re starting or expanding your lens collection, both platforms provide paths to creative growth.
