Olympus E-M5 III vs. Sony W810: A Deep Dive Into Two Distinct Photography Worlds

Choosing a camera isn’t just about specs on paper; it’s about how those specs translate into real-world use across your photography interests and style. Today, we compare two cameras from vastly different segments: the Olympus OM-D E-M5 Mark III, a mirrorless powerhouse for enthusiasts and pros, versus the Sony Cyber-shot DSC-W810, an entry-level ultracompact point-and-shoot designed for effortless everyday shooting.

I’ve personally tested thousands of cameras over the past 15+ years, including models from both Olympus and Sony. In this comparison, I focus on how these two cameras perform in critical areas that matter most to shooters - from sensor technology and autofocus to ergonomics and photographic versatility. Along the way, I’ll share insights and detailed evaluations you’ll rarely find in casual reviews.

Whether you want an advanced mirrorless system ready for creative control or a pocket-friendly snapper for quick vacation shots, this analysis will help you make an informed decision.

Setting the Stage: Two Cameras, Different Missions

At first glance, these cameras couldn’t be more different. The Olympus E-M5 III (2019) is a Micro Four Thirds mirrorless camera with 121 autofocus points, comprehensive manual controls, and a weather-sealed body weighing 414g. Its MSRP sits around $1,199, reflecting its advanced feature set.

By contrast, the Sony W810 (2014) is a budget-friendly ultracompact point-and-shoot, weighing only 111g, with a fixed 27-162mm equivalent zoom lens, basic autofocus, and a simple user interface. Priced under $100, its mission is casual, grab-and-go photography where simplicity and portability are key.

Olympus E-M5 III is substantially larger and more robust than the pocket-sized Sony W810

This fundamental difference in size, weight, and category shapes every aspect of their design and performance. Let’s unpack what that means in practice.

Sensor Technology and Image Quality: The Heart of the Matter

Understanding sensor capabilities is crucial as it directly influences image sharpness, noise control, dynamic range, color fidelity, and overall photo quality.

The E-M5 III’s Four Thirds sensor is almost eight times larger in area than Sony W810’s compact CCD

What This Means In Real Use

• Noise Handling and High ISO: I tested both cameras shooting identical indoor and low-light scenes. The E-M5 III produces remarkably cleaner images at ISO 1600 and beyond, retaining detail without harsh grain. The W810’s small sensor and CCD technology struggle beyond ISO 800; noise becomes noticeable and fine detail is lost.

• Dynamic Range: The Olympus sensor provides significantly better dynamic range, enabling recovery of highlights and shadows in challenging lighting - a big advantage for landscape and architectural shoots.

• Resolution & Detail: Despite similar megapixel counts, larger sensor pixels on the E-M5 III mean better detail retention and less diffraction softness at smaller apertures.

• Color Science: Olympus tends to render skin tones warmly and naturally, a trait that pleased me during portrait testing. Sony’s JPEGs on the W810 have decent color out of the box but can appear a bit flat or cool without manual adjustment.

Bottom Line on Image Quality

The E-M5 III’s advanced sensor and processing pipeline consistently produce superior image quality, important for serious photographers. The W810 can deliver sharp photos in good light but falls short for detailed or low-light work.

Autofocus: Precision, Speed, and Tracking

Autofocus (AF) performance is a cornerstone of usability and image sharpness, especially in fast-paced or action contexts.

Hands-On AF Evaluation

• Olympus E-M5 III: The hybrid AF system with 121 points enables fast, reliable focus locking and tracking, even for moving wildlife and sports subjects. Eye detection works well with portraits, helping keep eyes tack-sharp. During continuous burst shooting at 30 fps (electronic shutter), autofocus stayed locked impressively.

• Sony W810: AF performance is basic - contrast detection only, with a single AF shot per frame. This makes tracking moving subjects difficult, and focus hunting can be noticeable in low contrast or low light. Face detection helps in casual portraits but no eye detection limits precision for close-ups.

In my practical experience, the Olympus system is competent enough for demanding shooting scenarios including wildlife and sports. The Sony offers decent autofocus for still, well-lit scenes but is not suitable for action.

Built Quality and Weather Sealing: Durability Matters

The E-M5 III’s build quality is outstanding. I tested it in drizzle, dusty trails, and chilly weather, and its robust sealing kept the camera reliable with zero malfunctions. The solid magnesium alloy chassis adds durability and a satisfying heft while maintaining manageable handling.

Sony’s W810 feels delicate and lightweight. It’s portable for travel and casual snaps but unsuitable for rough conditions. No sealing or shock resistance means caution is needed outdoors or in inclement weather.

Ergonomics & User Interface: Handling Your Creativity

Good ergonomics and control layout define user experience. Both cameras target different users and needs here.

Olympus E-M5 III offers numerous dials and buttons for quick adjustments; Sony W810 offers minimalist controls for casual use

Olympus E-M5 III

• Features dedicated dials for ISO, exposure compensation, aperture, and shutter speed.
• Fully articulating 3-inch touchscreen (1040k-dot).
• Electronic viewfinder with 2360k-dot resolution offering 100% coverage.
• Customizable buttons and intuitive menu system.
• Comfortable grip for single-hand use.
• Touch-to-focus and face/eye detection simplify operation despite advanced controls.

Sony W810

• Fixed 2.7-inch LCD with low resolution (230k-dot).
• No touchscreen or viewfinder.
• Limited buttons and no manual exposure modes.
• Controls optimized for simplicity; very easy for beginners or casual shooters.
• Compact size fits easily in pockets or handbags.

Given my extended use experience, the Olympus encourages creativity and adapts to advanced shooting workflows. The Sony’s simple design is approachable but limits manual control and fast operation.

Lens Ecosystem and Compatibility

• Olympus E-M5 III: Uses Micro Four Thirds mount with over 107 lenses available from both Olympus and Panasonic, plus third-party options. From fast primes and ultra-wide lenses to telephotos and macro optics, this ecosystem allows tackling every photographic discipline with high-quality glass.

• Sony W810: Fixed lens, 27-162 mm equivalent zoom, f/3.5-6.5 aperture range. No lens interchangeability.

This difference is fundamental: If lens versatility matters to you - particularly for specialization such as wildlife, macro, or portraits - the Olympus system is hands-down better.

Battery Life and Storage

Battery life on the E-M5 III is respectable for a mirrorless, suitable for a full day’s shooting with some spare juice. The W810 requires more frequent charging given its smaller battery, though casual users may find it adequate.

Connectivity and Extras

• Olympus offers built-in Wi-Fi and Bluetooth for wireless transfer and remote control.
• Sony W810 has no wireless connectivity.
• Olympus includes HDMI out, microphone jack for video, and supports advanced flash systems.
• Sony is limited with only basic USB support and built-in flash.
