Olympus E-P1 vs Panasonic GH2: An Expert’s Real-World Battle of Two Micro Four Thirds Pioneers

When I look back at the evolution of mirrorless cameras, the Olympus PEN E-P1 and Panasonic Lumix GH2 stand out as significant milestones in the Micro Four Thirds (MFT) lineage. Both arrived in the early days of mirrorless technology and excited enthusiasts with compact form factors, interchangeable lenses, and solid imaging capabilities. But beyond the nostalgia, these cameras still resonate today for photographers considering vintage yet capable gear, or those seeking a foundation in MFT systems.

Having rigorously tested both across portrait sessions, landscape outings, wildlife chases, street expeditions, and even some video storytelling, I’m eager to share the nuanced differences that impacted my shooting experience. Whether you’re a budget-conscious beginner or a pro seeking a reliable backup, this detailed head-to-head will guide you to an informed choice grounded in hands-on insights and technical know-how.

Getting Comfortable: Size, Handling, and Design Philosophy

I first held the Olympus E-P1 and Panasonic GH2 side-by-side to immediately sense how their approaches to ergonomics and form factor set them apart.

The Olympus E-P1 is a rangefinder-style mirrorless with notably compact, boxy dimensions (121 x 70 x 36 mm) and a reassuringly light 355-gram body that fits effortlessly in the palm or a small bag. This design emphasizes portability and casual shooting, reminiscent of classic film PEN cameras but in a digital shell. It offers a minimalistic grip and straightforward handling, but that also means less tactile control space for quick adjustments.

In contrast, the Panasonic GH2 sports an SLR-style body (124 x 90 x 76 mm) and heavier heft at 442 grams, delivering a more substantial grip and an array of physical controls that cater to intensive photographic workflows. The deeper grip and textured body made longer shooting sessions more comfortable for me, especially when paired with telephoto or heavier zoom lenses. The button placements and dials, although abundant, felt intuitive after a bit of familiarization.

Looking from above, the GH2’s top plate reveals dedicated exposure compensation, ISO, and drive mode dials, granting quick one-handed access during dynamic shoots - a feature the E-P1 lacks. The Olympus relies on more menu navigation and less physical customization, which may frustrate experienced photographers preferring speed and hotkey access.

Practical takeaway: If you prioritize lightweight travel and street discreteness, the E-P1 excels. But for ergonomic comfort and manual control ease - critical in demanding situations like wildlife or sports - the GH2 wins hands down.

Peering into the Core: Sensor Technology and Image Quality

Image quality starts with the sensor and image processor, and here we see key differences that influence real-world shooting outcomes.

Both cameras utilize Four Thirds-sized CMOS sensors measuring 17.3 by 13 mm, sharing the same 2.1x crop factor. However, the E-P1’s 12-megapixel sensor (TruePic V processor) contrasts with the GH2’s more advanced 16-megapixel chip paired with Panasonic’s Venus Engine FHD processor.

In tests under controlled lighting, the GH2’s higher resolution manifests in crisper details - example: rock textures in landscapes and fine patterns in clothing. The increased pixel count, combined with superior noise processing, allows the GH2 to maintain better clarity at ISO 800 and above. The E-P1 shows grainier results beyond ISO 400, limiting its versatility in low-light scenarios.

Dynamic range also differs meaningfully. DxO Mark scores validate this difference: 10.4 EV for the E-P1 and a healthier 11.3 EV for the GH2, translating to better highlight retention and shadow detail on the latter. When shooting sunrise or sunset landscapes, the GH2 enabled me to recover more information in RAW files without unsightly clipping or boosted noise.

Color depth measures reveal the E-P1 slightly edges the GH2, with 21.4 bits versus 21.2 bits respectively. Olympus’s color science tends toward a warmer, filmic feel - ideal for skin tones and portraits. Panasonic’s result is more neutral and flexible for stylized edits.

Expert insight: While the GH2 delivers technically superior image sharpness, dynamic range, and higher native ISO ceiling (ISO 12800 vs. 6400), the E-P1 remains a charismatic shooter for portraits and street photography due to its mellow color rendition.

Peeking Behind the Lens: Autofocus System and Speed

Among the most consequential features for capturing fleeting moments is autofocus (AF) performance. Here I noticed the most tangible difference in everyday usability.

The Olympus E-P1 uses a contrast-detection AF system with 11 focus points and face detection. It performs adequately in well-lit, static scenes but struggles under low light or with moving subjects. Continuous AF works but lacks fluidity and tracking reliability. I found myself manually focusing more often to avoid hunting delays during portrait or wildlife shoots.

The Panasonic GH2 also relies on contrast-based AF but benefits from 23 focus points and advanced AF tracking capabilities inherited from the GH1 predecessor. Face detection and continuous AF tracking on the GH2 prove more responsive and maintain lock better during movement. While it is not the fastest autofocus system available today, it was noticeably superior to the E-P1 in action scenarios like sports or pets.

The continuous frame rate sits evenly at 3 fps on both, but the GH2 handles buffer limits better with faster SDXC-compatible storage formats.

Practical shooting tip: For static subjects in good light, the Olympus suffices. But if you frequently photograph fast-moving subjects - wildlife, sports, kids - the GH2’s autofocus reliability and expanded AF grid significantly improve your keeper rate.

Viewing and Composing: Displays and Viewfinders Compared

Since framing accurately affects creative vision, monitoring tools matter greatly. Here, the difference between the E-P1’s and GH2’s view technologies is stark.

The Olympus E-P1 features a fixed 3-inch 230k-dot HyperCrystal LCD with anti-reflective coating. It’s bright enough for daylight use but feels low resolution by today’s standard. Lack of a tilting or articulating screen limits framing versatility, especially in awkward or high-angle compositions.

Conversely, the Panasonic GH2 sports a 3-inch fully articulating LCD screen with an impressive 460k-dot resolution and touchscreen functionality. This flexibility enabled me to compose confidently from unique angles - ground level street photography, overhead crowd shots, or selfies - without contorting my posture.

Adding to compositional ease, the GH2 offers a high-resolution electronic viewfinder with 100% coverage and 0.71x magnification. This feature is particularly valuable in bright outdoor conditions where LCD glare hampers usability. The Olympus E-P1 lacks any viewfinder, requiring reliance entirely on its rear display.

Use case advisory: If you often shoot outdoors in bright light, or from creative angles, the GH2’s articulating screen and EVF provide a significant ergonomic advantage compared to the more minimalist E-P1.

Lens and System Compatibility: The Micro Four Thirds Ecosystem

Both cameras share the Micro Four Thirds mount, granting access to the same broad lens lineup of over 100 native lenses from various manufacturers. This extensive lens ecosystem covers everything from fast primes to super-telephoto zooms, macro lenses, and even specialty glass.

Because of their lens mount compatibility, your choice does not restrict optics selection, but lifestyle and shooting style considerations may influence lens pairing.

I found the E-P1, with its smaller body, pairs best with compact primes or pancake zooms, enhancing portability and street shooting fluency. The GH2 can comfortably accommodate larger telephoto zooms, making it more appropriate for wildlife, sports, and macro close-ups demanding enhanced reach or magnification.

Specialized Photography Discipline Testing

After extensive fieldwork, I want to share how each camera fares across common photography genres, reflecting my usage and typical prosumer expectations.

Portrait Photography: Skin Tones and Bokeh Charm

The Olympus E-P1’s color rendering and pleasant warm hues make portraits feel inviting and natural without aggressive processing. The 12MP sensor resolution allows softly detailed images that emphasize skin texture without harsh clarity. Coupled with fast Micro Four Thirds lenses, bokeh is smooth and beautiful despite the smaller sensor.

The GH2 ups resolution and sharpness, allowing tighter crops on eyes and facial details, beneficial for editorial work. It also supports advanced AF tracking, which excels in capturing candid expressions. The electronic viewfinder helps nail focus on eyes accurately.

For discerning portrait photographers, the GH2 is a more versatile tool, but the E-P1’s rendering still charms for lifestyle and casual studio use.

Landscape Photography: Dynamic Range and Resolution

In expansive views with complex lighting, the GH2’s greater dynamic range pays dividends. For example, when shooting dawn-lit mountains or shadow-rich cityscapes, the GH2 maintains highlight detail better and produces finely resolved details at 16MP.

The E-P1 performs respectably but increased noise beyond ISO 400 limits its nighttime or dim-moment performance. Its lower resolution means less ability to crop or print larger. Neither camera offers weather sealing, so care is needed shooting in adverse conditions.

Wildlife and Sports: Autofocus and Burst Rate

The GH2’s 23-point AF system with continuous tracking and robust buffer aids in capturing decisive moments of animals or athletes. The 3 fps burst is average but practical for its generation.

The E-P1’s AF lags in moving subjects, and its 3 fps frame rate combined with smaller buffer length challenged capturing action sequences. I only recommend Olympus for static wildlife or slow sports.

Street Photography: Discretion and Quickness

The low weight and rangefinder styling of the E-P1 make it superbly discreet for candid street work. Its minimalist controls blend seamlessly into urban environments.

The GH2’s bulk and loud shutter add visibility but better controls improve responsiveness once you master the layout. The articulating screen allows curious angles without attracting attention.
