Olympus OM-D E-M10 vs Panasonic Lumix DMC-ZS30: An In-Depth Camera Comparison from an Expert’s Lens

Choosing between cameras involves nuanced decisions that hinge on your shooting style, requirements, and budget. Having spent over 15 years evaluating hundreds of digital cameras across genres - from studio portraits to wild landscapes - I've developed a framework for assessing how a camera performs beyond just numbers on paper.

Today, we pit two very different but popular models against each other: the Olympus OM-D E-M10 - an entry-level mirrorless camera with Micro Four Thirds flexibility - and the Panasonic Lumix DMC-ZS30 - a compact, superzoom fixed-lens point-and-shoot designed for ultimate portability and reach. Both debuted around the early 2010s but serve distinct photographic niches.

Over many hours of hands-on testing and side-by-side shooting, I’m sharing a comprehensive analysis targeting informed photographers seeking practical clarity. We’ll cover everything from sensor tech and handling to autofocus performance and genre-specific suitability, concluding with tailored recommendations.

First Impressions: Design, Size, and Handling

Before cracking open the spec sheets, I always pick the two cameras up to feel their ergonomics and build quality. Handling profoundly influences how intuitive shooting feels - and I’ve learned this lesson the hard way over thousands of shooting sessions.

Olympus E-M10: Classic Mirrorless Form Factor

The Olympus E-M10 inherits the classic SLR-style body with a robust grip, abundant dials, and a well-organized button layout. Its all-metal construction offers solidity at an entry-level price point. The size is compact but not tiny, striking a nice balance between portability and comfortable single-handed use for extended periods.

Panasonic ZS30: Ultra-Compact Travel Companion

In stark contrast, the Panasonic ZS30 is a pocketable travel zoom, much smaller and lighter than the E-M10. Its plastic body keeps weight down but also means a less premium feel. Controls are simplified - fewer physical buttons and a fixed screen - reflecting its design as a grab-and-go convenience camera.

The image above visually contrasts their physical footprint and user interface. The E-M10’s thicker grip and well-spaced dials lend themselves to precise manual control, which photographers appreciate for creative shooting. Meanwhile, the ZS30’s minimalistic design suits casual shooting scenarios or travelers prioritizing packability.

Sensor Size and Image Quality: The Heart of the Matter

At the core of any camera’s imaging capabilities is the sensor - a gateway for light and detail capture.

Olympus E-M10: Micro Four Thirds Sensor with Good Resolution

Olympus’s E-M10 sports a Four Thirds-sized CMOS sensor measuring 17.3x13 mm, with a resolution of 16 megapixels. This sensor size is larger than typical compact cameras and facilitates better dynamic range, color fidelity, and noise control - all confirmed by standardized tests.

The sensor area of about 225 mm² permits better light gathering than the smaller sensor in the ZS30, allowing for cleaner images, especially in dim conditions.

Detailed metrics from DxOMark rank the E-M10 with a respectable score of 72 overall. It scores well in color depth (22.8 bits) and dynamic range (12.3 EV), showcasing its capability to capture nuanced tonal gradations from shadows to highlights.

Panasonic ZS30: Small 1/2.3" Sensor with High Zoom Versatility

By comparison, the ZS30 has a much smaller 1/2.3" CMOS sensor measuring just 6.17x4.55 mm and packing 18 megapixels. Although its resolution is slightly higher, each pixel is physically smaller, affecting light sensitivity and noise performance.

The tiny sensor area of roughly 28 mm² puts it at a disadvantage in low-light scenarios and limits depth of field control. Detailed lab scores are unavailable, but general consensus places this sensor in the compact class - good for daylight shooting but prone to noise and limited dynamic range under challenging lighting.

This comparative image underscores the size gulf, which directly impacts image quality outcomes you can expect in the real world.

Handling and Interface: Making Photography a Pleasure

The user interface and ergonomics are key during prolonged shoots, especially for professionals or serious enthusiasts.

Olympus E-M10: Intuitive Controls and Versatile Display

The E-M10 features a tilting 3-inch touchscreen LCD with 1,037k dots, allowing for flexible high-angle or low-angle framing. The built-in electronic viewfinder (EVF) with 1,440k dots and 100% coverage offers a bright, clear view for precise composition even in bright sunlight.

Touchscreen focus and menu navigation are responsive. The camera’s array of physical dials for shutter speed and exposure compensation enable creative control without digging through menus.

Panasonic ZS30: Simplified Screen, No EVF

The ZS30 has a 3-inch fixed LCD with slightly lower resolution (~920k dots). It lacks an EVF, which can be a downside in bright outdoor use - the LCD can be hard to see under harsh light. The touchscreen functionality exists but is less integral.

Controls are minimal, suited to point-and-shoot simplicity rather than deliberate manual operation.

Lens Options and Optical Versatility

An often underestimated aspect, lens systems can make or break photographic versatility.

Olympus E-M10: Micro Four Thirds Lens Ecosystem

The E-M10 mounts Micro Four Thirds lenses, one of the most comprehensive and affordable mirrorless lens catalogs available - with over 100 lenses ranging from ultra-wide to super-telephoto, plus excellent macro options.

The 2.1x crop factor compared to full-frame means you get a useful telephoto reach from moderate focal lengths, and wide-angle options remain reasonably wide, making it excellent for diverse shooting styles, from landscapes to portraits.

Panasonic ZS30: Superzoom Fixed Lens

In contrast, the ZS30 sports a fixed 24–480 mm equivalent zoom lens (20x optical zoom) with a variable aperture of f/3.3–6.4. This massive zoom range is terrific for travel and wildlife aficionados wanting reach in a pocket camera without swapping lenses.

However, this comes at a cost: the variable aperture narrows considerably at telephoto lengths, impacting low-light usability and bokeh quality. Macro focus as close as 3 cm is a bonus in this category, though.

The inability to swap lenses limits creative options significantly.

Autofocus Performance: Speed, Accuracy, and Tracking

Autofocus is a critical factor, especially for action, wildlife, and sports photography.

Olympus E-M10: Contrast-Detection with 81 Focus Points

The E-M10 uses a contrast-detection autofocus system with 81 focus points, including face detection and touch AF. While it lacks phase-detection pixels, the system performs robustly in good light, with decent continuous AF for tracking moving subjects.

Eye detection is effective enough for portraits, though not as advanced as newer mirrorless hybrids. AF speed is satisfactory for entry-level mirrorless but not at pro-level burst rates.

Panasonic ZS30: 23-Point Contrast-Detection AF with Tracking

The ZS30 also employs contrast-detection with fewer focus points (23). It boasts face detection but lacks eye AF.

Burst shooting tops out at 10 fps, marginally faster than the E-M10’s 8 fps, which is impressive for a compact. However, AF acquisition slows noticeably in low light.

Neither camera supports advanced phase-detect hybrid AF; thus, neither excels in fast-action autofocus scenarios.
