Nikon Coolpix S810c vs Olympus OM-D E-M5 II: A Deep Dive Into Compact Convenience and Mirrorless Versatility

Choosing a camera today means weighing many factors - sensor quality, autofocus speed, physical handling, and even how it fits your photographic lifestyle. With both Nikon's Coolpix S810c and Olympus' OM-D E-M5 II standing prominently in very different segments, I wanted to bring my 15+ years of hands-on camera testing experience to compare these two. Although they sit at distinct ends of the spectrum - a compact superzoom fixed-lens shooter versus a sophisticated interchangeable-lens mirrorless system - understanding their real-world performance nuances helps clarify who they are really made for.

In this comprehensive comparison, I tested both extensively across multiple photographic disciplines, dissected their technical specs, evaluated ergonomics, and considered value. Whether you’re a casual snapshooter or a seasoned pro hunting for a versatile workhorse, this article will guide you through.

Making Size Matter: Physical Design and Handling

Anyone who spends hours behind a camera knows that form and feel are not superficial things - they affect how instinctively you shoot and how long you can comfortably hold the gear.

The Nikon S810c is a pocketable compact, with dimensions of 113 x 64 x 28 mm and a featherlight 216 grams. Its fixed lens, with a modest aperture of f/3.3-6.3, sits behind a 1/2.3" sensor, so you’re getting an ultra-portable everyday camera with an impressive 12x zoom range (25-300 mm equivalent).

In contrast, the Olympus OM-D E-M5 II is genuinely a different beast. Measuring 124 x 85 x 45 mm and weighing in at 469 grams, it sports a classic SLR-style mirrorless body with a Micro Four Thirds mount. This camera is designed for enthusiasts who want the flexibility of changeable lenses, full manual control, and ruggedness - you get weather-sealing and a robust magnesium alloy shell.

During side-by-side grips, the Nikon feels more toy-like but excellent for grab-and-go or travel without bulking your bag. The OM-D’s sizeable grip and pronounced dials give far better physical control, especially when paired with larger lenses. For long photo walks or professional assignments, I found the Olympus far more comfortable, especially given the articulating screen and viewfinder.

If you value pocketability and minimal fuss, Nikon’s S810c wins hands-down. For those wanting a true photographic tool for diverse shooting, the Olympus reigns.

Control at Your Fingertips: Layout and Interface

Operating a camera intuitively can make the difference between a missed moment and a decisive shot. Both these cameras also represent different ergonomic philosophies.

The Nikon S810c employs a minimalistic control scheme. Its touchscreen interface fills the gaps where physical buttons are scarce. This can be a boon for beginners or smartphone natives who prefer tapping quickly. However, the lack of traditional aperture or shutter priority modes means some creative exposure control is impossible.

Olympus has a distinct advantage here. The OM-D E-M5 II features a top LCD panel, an electronic viewfinder, and a rich array of physical dials for shutter speed, exposure compensation, and more. The menus are structured but deep, suiting enthusiasts who want immediate access to settings without diving into touch menus in unpredictable situations.

In my real-world use, shooting street or sports with the Olympus felt more confident - turn a dial, check the EVF, lock focus with precision, all without taking eyes off the scene. The Nikon, though touchscreen responsive, sometimes felt limiting when rapid adjustments were needed.

For users who prize quick tactile control or shoot in dynamic environments, the Olympus is superior. Meanwhile, casual users or vloggers who enjoy touch gestures will appreciate the Nikon’s straightforward interface.

Peering Into The Heart: Sensor Size and Image Quality

Sensor size is one of the most fundamental determinants of image quality. The Nikon S810c uses a diminutive 1/2.3” BSI-CMOS sensor with 16 megapixels. Although advances in compact sensor technology have improved noise control and dynamic range since the S810c’s 2014 launch, it’s still inherently limited in capturing fine detail and performing well under low light.

The Olympus E-M5 II leverages a much larger Four Thirds MOS sensor measuring 17.3 x 13 mm, also with 16 megapixels but vastly superior in terms of color depth, dynamic range, and high ISO performance.

My tests underscored this gap: images from the Olympus consistently retained detail in highlights and shadows with less noise beyond ISO 800. The Nikon started showing chroma noise and lacked the tonal gradation needed for professional landscape work. Additionally, Olympus’ sensor supports raw capture, giving greater flexibility in post-processing – an essential for serious photographers.

The Nikon’s fixed lens and sensor combination excel for quick snapshots, travel photography, and casual daylight shooting but falters in demanding scenarios such as low-light events or wide dynamic range landscapes.

Viewing Your World: Screens and Viewfinders

Neither camera is sidelined when it comes to composing your shots, but again, they cater to different preferences.

The Nikon’s large 3.7” touchscreen with 1229k dots provides bright viewing and simple menu navigation. However, there is no electronic or optical viewfinder, which can make composing in bright sunlight frustrating.

The Olympus sports a vibrant 3" fully articulating touchscreen and an excellent electronic viewfinder with 2.36 million dots of resolution and 100% coverage. This combination offers immense flexibility - shoot close to the ground, over crowds, or selfie-style; track moving subjects more confidently with the EVF.

During outdoor shoots, I relied heavily on Olympus’ EVF for accuracy, especially under harsh sunlight, where LCD glare hampered the Nikon. If you prefer shooting candid moments or sports, the EVF is indispensable.

For casual or indoor use, Nikon’s large, detailed screen will suffice. For more varied shooting environments, Olympus’ dual viewing options are a notable advantage.

Shooting Scenarios: Sample Works from Both Cameras

Real-world shooting tells us more than specs ever can. Here’s a side-by-side gallery highlighting differences in image rendering, zoom reach, and color science.

• Portraits: Olympus’ 5-axis stabilization and option to mount fast primes deliver exceptional creamy bokeh and accurate skin tones. Nikon’s smaller sensor can struggle with natural background blur and fine hair details.
• Landscape: Olympus’ greater dynamic range and higher resolution retain textures in foliage and sky gradients. Nikon images appear flatter with some detail loss in shadows.
• Wildlife: Olympus’ faster AF, especially with telephoto lenses, excels for birds in flight. Nikon’s 12x zoom helps get closer but autofocus hunting reduces keeper rates.
• Sports: Olympus’ 10 fps burst and sophisticated AF tracking make freezing action viable. Nikon’s 8 fps is functional but focus limitations impact sharpness.
• Street: Nikon’s compact size aids in discretion; Olympus is bulkier but offers faster response and adaptability.

The samples clearly reveal the Olympus as a higher performer across most scenarios owing to superior optics and sensor technology.

Autofocus: The Eyes of Performance

Good autofocus (AF) can make or break certain genres like wildlife, sports, or street photography. Both cameras employ contrast-detection with face detection, but their implementations diverge dramatically.

The Nikon S810c has 9 AF points with contrast detect and face detection, adequate for everyday shooting but prone to occasional hunting in low light or fast motion scenes.

The Olympus OM-D E-M5 II, by contrast, boasts 81 focus points and advanced contrast detect with predictive tracking. Its AF system is impressively responsive in live view and EVF modes, supporting continuous (AF-C) and selective-area tracking. It also boasts focus bracketing and stacking useful for macro and landscape photography.

In my experiences photographing running children and energetic pets, Olympus’ AF reliability and speed resulted in higher keeper percentages, while Nikon often missed focus or lagged behind fast subjects.

Durability and Environmental Resistance

Weather sealing is an overlooked but vital feature for those who shoot outdoors regularly. Olympus engineered the E-M5 II with splash and dust resistance built into its rugged magnesium body – perfect for unpredictable environments including light rain or dusty trails.

The Nikon S810c is not weather-sealed, which limits its reliability in poor weather or rough handling despite a lightweight design.

If you anticipate shooting in challenging climates or want a camera that can handle the rigors of professional work, Olympus has the clear edge.

Lens Ecosystem and Flexibility

One of the main differences between a fixed-lens camera and an interchangeable lens system is the ability to evolve your gear alongside your skills and needs.

Nikon S810c comes with a built-in 25-300mm equivalent lens but that’s it. It’s not designed for lens changes or upgrades.

Olympus supports the extensive Micro Four Thirds system with over 100 lenses available - from fast primes for portraits, macro lenses for intricate detail, to super-telephoto zooms for wildlife and sports. The system continues to receive updates, ensuring long-term usefulness.

For photographers who want creative freedom, the Olympus wins hands-down. Nikon appeals to those who value simplicity above all else.

Battery Life and Storage

Battery longevity affects how much you can shoot without recharging - especially important for travel and events.

The Nikon S810c uses a compact EN-EL23 battery providing roughly 270 shots per charge, fairly standard for compacts of its class.

Olympus’ BLN-1 battery delivers about 310 shots, improved with Eco modes and optional battery grips.

Both cameras use SD cards, but Olympus supports the faster SDXC format needed for high-speed continuous shooting and video.

Video Performance and Connectivity

Videographers will notice key differences. Nikon supports 1080p at 30fps with stereo audio, but lacks microphone input, limiting audio control.

Olympus can record full HD at up to 60fps in various codecs, and has a microphone jack for improved sound recording. Its 5-axis stabilization particularly benefits handheld video.

Both support Wi-Fi for image transfer and remote control, but neither have Bluetooth or NFC.

For casual video, Nikon is serviceable; for semi-pro streamlined video, Olympus offers more compelling features.

Pricing and Who Each Camera is For

At $350, the Nikon Coolpix S810c is positioned as an inexpensive travel point-and-shoot. It’s great for casual users, social media enthusiasts, or those seeking a straightforward camera with a long zoom in a pocketable format.

The Olympus E-M5 II, priced around $700 (body only), appeals to photography enthusiasts and pros looking for a lightweight yet capable mirrorless body with excellent image quality and professional-grade features. It even holds value for nature photographers who prize weather resistance and high-performance autofocus.
