Nikon Coolpix S810c vs Olympus SP-620 UZ: An Expert’s Deep Dive Into Small Sensor Superzoom Compacts

When diving into the world of superzoom compact cameras, it’s easy to get dazzled by flashy zoom ranges and megapixel counts. But as someone who’s tested and handled thousands of cameras over 15 years, I caution you not to get seduced by specs alone. Real-world usability, image quality, ergonomics, and value for money count - a lot.

Today we’re putting two superzoom compacts head-to-head, both wielding small 1/2.3” sensors but each with its own quirks and charms: the Nikon Coolpix S810c (hereafter Nikon S810c) and the Olympus SP-620 UZ.

This isn’t your run-of-the-mill spec race. Rather, I’ll peel back layers of technical details, hands-on ergonomics, and real-world test results across photography genres and use cases. Whether you’re a weekend traveler, casual portraitist, or plan to zoom in on wildlife from your backyard, I’ll help you figure out which camera suits your style and budget best.

Let’s get cracking.

Size and Handling: The Feel Factor You Can’t Ignore

The first thing you notice when comparing these two cameras side-by-side is their physical presence.

The Nikon S810c is a svelte, pocket-friendly compact, weighing a mere 216 grams and sporting trim dimensions of 113x64x28 mm. In contrast, the Olympus SP-620 UZ is almost twice as heavy at 435 grams and chunkier at 110x74x74 mm - more of a mini bridge camera than a pure compact.

This size difference isn’t just about heft - it impacts pockets (and nerve) on travel days. The Nikon’s slim design makes it nearly invisible when tossed in a jacket pocket, while the Olympus demands a dedicated pouch or thoughtful backpack organization.

Ergonomics-wise, the Nikon embraces minimalism: no viewfinder, a curved grip that fits average hands decently, and a sizeable (but fixed) 3.7-inch touchscreen. Conversely, the Olympus relies purely on physical buttons and a smaller, lower-resolution 3-inch LCD.

While neither offers the clubs-for-thumbs deep grip of a DSLR, the Olympus’s bulk provides a more stable feel when zoomed out, especially useful with its enormous 21x telephoto reach.

If you prize ultra-portability and a modern touchscreen interface, the Nikon S810c has your back. If zoom superpowers and a more substantial grip comfort you (and you don’t mind the bulk), the Olympus SP-620 UZ takes this round.

Design Language and Controls Up Close

Moving beyond mere size, controls can make or break the shooting experience. Quick access to modes, exposure options, and zoom matter most when you’re chasing elusive moments.

At the top, the Nikon S810c sports modern, minimal controls, focusing on touchscreen-based navigation with just a few physical buttons and a zoom rocker. Its rear-mounted touch interface is responsive and intuitive but demands finger precision - it lacks tactile buttons for exposure compensation or mode dials, potentially slowing down seasoned shooters wanting quick adjustments.

The Olympus leans into traditional control layouts - physical buttons for flash, scene modes, and zoom - with more tactile feedback. It’s not fancy, but for users who hate fumbling with touchscreens, this is a plus.

Neither camera offers manual exposure control modes like aperture or shutter priority, reflecting their point-and-shoot market niches. However, both provide face detection AF and tracking, with Nikon supporting continuous autofocus in video unlike the Olympus.

So if you’re used to touchscreen swiping and know your way around smartphone-style interfaces, Nikon’s layout will delight you. If you prefer physical buttons and preset modes at your fingertips, Olympus’s approach remains dependable.

Sensor Technology & Image Quality: The Heart of the Matter

Here’s where many cameras with 1/2.3" sensors struggle - the sensor may be small, but image quality expectations can’t shrink accordingly. Both models pack a 16-megapixel resolution on identically sized sensors measuring roughly 6.17x4.55 mm.

Nikon’s S810c embraces a backside-illuminated CMOS sensor, which theoretically offers better low-light sensitivity and dynamic range than older CCD counterparts. Olympus SP-620 UZ, meanwhile, uses an older CCD sensor, with technology dating back several years.

In my controlled lab tests and outdoor shoots, this difference mattered. The Nikon delivered sharper images with better detail preservation in shadows and midtones, while the Olympus images appeared softer with slightly muted colors.

Low-light shooting is a notorious challenge for small sensors. Nikon’s CMOS sensor held its ground better up to ISO 800, exhibiting more usable detail and lower noise than Olympus, which showed grain and color artifacts creeping in beyond ISO 400.

Both cameras max out at ISO 3200, but you’ll rarely want to go beyond ISO 800 on the Olympus without sacrificing image quality.

Lens and Zoom: How Far Can You Reach?

Superzoom cameras are all about versatility in focal length - from wide-angle landscapes to super-telephoto wildlife shots.

• Nikon S810c: 25-300mm equivalent (12x zoom), max aperture f/3.3-6.3
• Olympus SP-620 UZ: 25-525mm equivalent (21x zoom), max aperture f/3.1-5.8

The Olympus’s 21x zoom advantage is impressive on paper, doubling Nikon’s reach. In practice, that telephoto length lets you frame distant subjects - birds, sports action, or city details - without cropping later. However, all superzoom lenses at extreme telephoto ranges tend to soften images and suffer from chromatic aberration, especially on small sensor compacts.

The Nikon lens shows a slight edge in sharpness and reduced distortion at wide and mid-range zooms thanks to more modern optics, plus optical image stabilization helps keep shots steady.

The Olympus features sensor-shift stabilization, which is generally good, but its lens has more noticeable softness at the farthest zoom, especially in less-than-ideal light.

For everyday shooters wanting a balance of wide and telephoto, Nikon’s zoom is adequate and sharper. For wildlife or extreme telephoto enthusiasts on a budget, Olympus’s zoom is tempting but expect some tradeoffs in image crispness and focus accuracy.

Autofocus and Shooting Performance: Capturing the Moment

Autofocus systems often reveal the real shooting potential - when you need focus to lock fast and track subjects accurately.

The Nikon S810c employs contrast-detection AF with nine focus points and face detection, delivering continuous AF during video as well. I found its autofocus to be snappy in good light and reliably accurate tracking on moving subjects.

Olympus’s SP-620 UZ uses contrast detection but with unknown focus points (no cross points) and no continuous AF during video. It struggles more in challenging light and on fast-moving subjects. In burst shooting, Olympus did not publish continuous shooting specs, while Nikon offers 8 fps - respectable for this class.

For wildlife or sports, Nikon’s better autofocus system and faster burst speeds give it a tangible edge for capturing decisive action.

Display and User Interface: How You See Your Shot Matters

Neither model sports a viewfinder, relying solely on LCDs for composing. This can be annoying in bright sunlight.

The Nikon’s 3.7-inch touchscreen boasts 1229k-dot resolution, big and bright enough for most daylight situations. Touch autofocus and menu navigation are fluid, making it friendlier for novices or those who prefer minimal button jabbing.

The Olympus has an older 3-inch TFT LCD with a meager 230k-dot resolution, which feels dim and pixelated by today’s standards. Without touchscreen support, you navigate menus with buttons, slower but perhaps preferred by traditional camera users.

If you often shoot outdoors or want quick settings changes, Nikon’s bright touchscreen display is the clear winner here.

Battery Life and Storage: Staying Powered and Ready

Nikon includes a proprietary battery pack (EN-EL23) delivering around 270 shots on a charge - a modest number typical for compact cameras with power-hungry touchscreens and Wi-Fi.

The Olympus uses four AA batteries (user-supplied), which is great for travel when recharging isn’t an option. You can carry spares easily, and alkaline or NiMH rechargeables work fine. Olympus did not specify battery life in shot count, but generally, it tends to be longer than proprietary packs for casual shooting.

Both cameras accept SD cards (microSD in Nikon’s case), so storage compatibility isn’t a concern.

For globetrotters without access to electricity, Olympus’s AA system offers peace of mind and flexibility. Nikon’s proprietary battery encourages charging and uninterrupted shooting when you’re home or at powered stops.

Connectivity and Extra Features: Staying Linked and Creative

The Nikon S810c offers built-in Wi-Fi and GPS, simplifying photo sharing and location tagging - fits the social media-driven user profile.

Olympus SP-620 UZ includes Eye-Fi compatibility (wireless SD cards), but no built-in Wi-Fi or GPS. This older model reflects a pre-Wi-Fi era approach.

Neither has microphone ports or headphone jacks for serious video work, and both top out at Full HD video, with Nikon offering 1080p at 30fps and Olympus limited to 720p.

The Nikon’s touchscreen facilitates quick white balance adjustments and some creative filters, while Olympus limits you to preset scene modes.

If staying connected and geotagging photos on the fly is important, Nikon is the natural choice.

Real-World Shooting Across Genres: Strengths and Shortcomings

Let me break down how both cameras perform across popular photography disciplines and use cases based on extensive testing:

Portrait Photography

• Nikon: Good skin tone rendition with the CMOS sensor; gentle bokeh at 25mm and short portraits works, aided by face detection AF and touch focus.
• Olympus: Decent color but flatter skin tones, with harsher contrast. Macro mode lets you get close (1cm), but no precise focus confirmation.

Neither offers manual exposure or aperture control for creative portrait lighting; Nikon’s cleaner images make it preferable here.

Landscape Photography

• Nikon: Better dynamic range and detail retention give more life to landscapes; fixed LCD limits composition in bright sun.
• Olympus: Slightly wider zoom at 25mm, but softer images and lower resolution screen hamper framing. No weather sealing on either.

Landscape shooters won’t be fully satisfied with image quality, but Nikon ekes ahead.
