Olympus E-M10 III vs Panasonic FX700: Two Distinct Cameras for Different Photographer Profiles

Having spent over fifteen years rigorously testing cameras across all photography genres, I often encounter devices that target fundamentally different users yet might appear at first glance as competitors. The Olympus OM-D E-M10 Mark III and the Panasonic Lumix DMC-FX700 are such an intriguing pair. Released seven years apart and belonging to different categories - one a mirrorless interchangeable lens camera with a Micro Four Thirds sensor, the other a compact fixed-lens point-and-shoot - they cater to different photography ambitions and technical expectations.

In this article, I will draw on hands-on experience with both models (and their contemporaries) to provide an in-depth, honest, and practical comparison covering all major photography disciplines, technical nuances, and real-world usability. My goal is to empower you to make an informed decision based on your needs, style, and budget.

A Tale of Two Bodies: Design, Size, and Handling

One of the most obvious differences is the form factor. The Olympus E-M10 III adopts a classic SLR-style mirrorless body design, featuring substantial grip and an intuitive control layout aimed at enthusiasts stepping up from smartphones or compact cameras. In contrast, the Panasonic FX700 is a sleek, pocket-friendly compact designed for casual shooting and travel convenience.

Looking side-by-side, the size and ergonomics contrast sharply:

At approximately 122x84x50mm and weighing 410 grams, the Olympus is nearly double the size and weight of the Panasonic’s 104x56x25mm and 176 grams - a notable consideration if portability is a priority.

From my time testing the E-M10 III, its pronounced grip and well-placed dials lend themselves to confident, tactile control in various shooting conditions. That said, smaller hands might find the Panasonic’s diminutive footprint easier to carry all day without fatigue.

Top-Down: Controls and Interface Insights for Intuitive Shooting

Looking at the top panel reveals a snapshot of their user interaction philosophies:

The Olympus E-M10 III features a mode dial with manual, aperture, shutter, and program modes - plus dedicated buttons for ISO, video recording, and a configurable Fn button. These afford rapid adjustments that professional or enthusiast photographers appreciate.

Meanwhile, the Panasonic FX700 has a simpler layout centered around auto and scene modes, with fewer physical buttons to avoid confusion for casual users. The FX700 lacks dedicated exposure controls like aperture priority or manual exposure, reflecting its design focus on simplicity over customization.

If you thrive on manual control and quick settings access, the Olympus will feel like home - the Panasonic better suits those who prefer point-and-shoot convenience without fiddling.

Sensor Technology: The Heart of Image Quality

No discussion is complete without considering sensor size and capabilities, which profoundly influence image quality, depth of field, and overall visual expression.

Here's a comparative graphic outlining sensor specs:

• Olympus E-M10 III: Four Thirds CMOS sensor at 16MP (17.4 × 13 mm)
• Panasonic FX700: 1/2.3" CMOS sensor at 14MP (6.08 × 4.56 mm)

The sensor on the Olympus is approximately 8 times larger in surface area, a key reason why its images can deliver better dynamic range, lower noise, and more creative control over background blur.

During my landscape shoots, the E-M10 III’s sensor impressively retained highlight and shadow detail thanks to its native dynamic range, crucial for high-contrast scenes. In contrast, the Panasonic’s smaller sensor struggles comparatively under challenging lighting, often yielding images with less tonal nuance and more visible noise above ISO 800.

For portrait work, the Olympus’s sensor allows for better subject-background separation, resulting in more attractive bokeh - a critical factor for skin tone rendition and artistic expression.

LCD and Viewfinder: Framing Your Shot

Both cameras provide 3-inch LCDs, but they differ vastly in resolution and viewing options.

The Olympus offers a 1040k-dot tilting touchscreen, giving flexible angles for shooting from low or high perspectives and responsive touch focusing - a boon for composing creative shots on the fly.

Meanwhile, the Panasonic embeds a fixed LCD at only 230k dots, considerably less sharp and no articulation - limiting some compositional freedoms, especially for awkward angle shooting.

Notably, the Olympus E-M10 III includes a built-in electronic viewfinder (EVF) with a 2360k-dot resolution, allowing photographers to compose in bright sunlight where LCDs can be hard to see. The FX700 lacks a viewfinder entirely, relying solely on rear screen framing.

From my fieldwork, this EVF proves indispensable for portraits, street photography, and wildlife where precision composition is critical under demanding lighting.

Autofocus Performance and Speed in Real Life

Autofocus (AF) is a vital factor across nearly all photography areas. The Olympus gains a substantial advantage here, largely due to its 121-point contrast-detection AF system with face detection and subject tracking.

The Panasonic FX700 employs a more rudimentary contrast-detection AF with fewer focus points and lacks face or eye detection.

In wildlife and sports shooting scenarios, I tested the Olympus continuous AF mode and found it capable of maintaining sharp focus on erratically moving subjects, thanks to its higher burst rate and better AF algorithms. The FX700, while decent for snapshots, struggled to keep pace with action, often hunting or missing focus.

Here is a snapshot of sample images captured with both cameras illustrating autofocus sharpness and burst handling:

Detailed Photography Genre Analysis

Let me break down how each camera fares in specific photography pursuits based on extended hands-on usage:

Portrait Photography

The Olympus E-M10 III’s Four Thirds sensor and fast lenses (available via Micro Four Thirds mount) facilitate creamy bokeh and flattering skin tones. Face detection AF works well, ensuring critical sharpness on the eyes during portraits.

The Panasonic FX700, with its small sensor and variable aperture f/2.2–5.9 lens, produces less separation and struggles in low light, giving flatter-looking portraits.

Landscape Photography

Here, the Olympus’s higher resolution and sensor dynamic range allow for richly detailed landscapes with minimal noise across ISO ranges. Weather sealing is absent on both, so a rain cover is advisable outdoors.

The Panasonic’s compact form favors travel landscapes but compromises image quality and lacks RAW support - limiting post-processing flexibility.
