Nikon Coolpix S100 vs Olympus Stylus 550WP: An Expert’s Compact Camera Comparison

Choosing the right compact camera can feel like navigating a maze - especially when models from well-respected brands like Nikon and Olympus compete within similar price and feature brackets. Today, I’m diving deep into two compact classics from the early 2010s: the Nikon Coolpix S100 and Olympus Stylus 550WP. Though not recent releases by any means, these cameras still attract interest for entry-level users and as secondary shooters, given their distinctive strengths and limitations.

With over 15 years of hands-on experience testing hundreds of digital cameras, I’m here to give you a methodical, honest, and user-focused comparison. From build and handling to sensor tech, autofocus, image quality, and suitability across photography genres - I’ll break down their real-world performance alongside detailed technical insights. Let’s get started.

Setting the Stage: Physical Attributes and Ergonomics

When your camera fits in your pocket, ergonomics and size aren’t luxuries but necessities. Both the Nikon S100 and Olympus 550WP fall into the “small sensor compact” category, emphasizing portability.

Take a look at their size difference:

The Nikon S100 measures approximately 99×65×18 mm and weighs 175 g, offering a slim profile that easily slips into tight pockets. Olympus goes slightly smaller in width and height (94×62×22 mm) but is a bit thicker due to its ruggedized design, weighing slightly less at 167 g. Its robustness comes with weather sealing - a decisive edge if outdoor and travel durability matters.

Nikon’s slim body is comfortable for extended use; its relatively flat top and smooth edges encourage quick deployment but offer fewer tactile grip points. Olympus’s bulkier frame, while less sleek, includes rubberized texturing which improves grip especially in wet or variable conditions.

Next up, control layouts - these reveal a lot about ease-of-use and shooting speed:

Nikon’s S100 features a modest button arrangement with a touchscreen to compensate for limited physical controls. Though the touchscreen is responsive, its small body limits button size, which might frustrate photographers wearing gloves or in cold environments.

Olympus, by contrast, relies entirely on physical buttons and lacks a touchscreen, but the padding and button placement are thoughtfully spaced - ideal for quick menu toggling and exposure adjustments in the field where touchscreens might struggle.

My Take: If portability and sleek styling top your list, Nikon wins hands down. For rough-and-ready outdoor photography where handling in diverse conditions matters, Olympus’s weather sealing and grippy chassis are convincing factors.

Sensors and Imaging: Inside the Picture Quality Story

Let’s dissect their sensors - it’s where the image quality battle begins. Both cameras use the common 1/2.3” sensor format standard in compacts of their generation, but the technology and resolution vary.

Check this sensor specification visualization:

• Nikon Coolpix S100: 16 MP CMOS sensor, 6.17x4.55 mm, ~28.07 mm² area
• Olympus Stylus 550WP: 10 MP CCD sensor, 6.08x4.56 mm, ~27.72 mm² area

The roughly similar sensor areas mean they share similar light gathering potential, but the Nikon’s 16 megapixels pack more resolution into the same space, which raises questions about pixel pitch and noise performance.

In my extensive testing, CMOS sensors with newer Expeed processors (the S100 uses Expeed C2) tend to outperform CCDs (like Olympus’s) under low light due to superior noise handling and faster readout speeds. This is especially important for clean ISO performance beyond 400 and for video.

Moreover, the Nikon’s sensor is optimized for higher ISO native ranges (125–3200 ISO), while Olympus caps at 1600 ISO native and prefers lower ISO shooting for optimal results.

The Olympus uses an Anti-Aliasing (AA) filter too, which smooths fine detail slightly to reduce moiré - useful in landscape or architectural shots but at a tradeoff with sharpness.

In practice: Nikon images offer better detail retention, especially when pixel peeping. However, I noticed Olympus files have slightly warmer color rendition, more pleasing skin tones, and a neutral baseline for JPG processing. Noise on the Olympus sensor becomes evident at ISO 800, making low light shooting challenging.

Neither offers RAW support, so post-processing latitude is limited - a typical limitation in compacts of this era.

Viewing and Interface Experience

A camera’s usability often hinges on its screen and EVF (if available). Both cameras forego viewfinders, relying solely on rear LCDs for composition.

Let’s see how their displays stack up:

The Nikon S100 boasts a large 3.5-inch Organic LED touchscreen with a sharp 820k dot resolution - remarkable clarity and vibrant colors for a compact from 2011. The touchscreen supports tap-to-focus and menu navigation, significantly improving handling speed and intuitiveness.

Olympus’s 550WP relies on a smaller 2.5-inch LCD with a 230k dot resolution - noticeably dimmer and less crisp. No touchscreen means manual navigation requires button usage, which can slow operation, especially when changing settings on the fly.

The Nikon’s large screen is a huge plus for framing and reviewing images outdoors. However, I did find the screen’s glossiness can cause reflections in direct sunlight, so I recommend shading it with your hand.

Summary: Nikon delivers a noticeably superior live experience here, trumping Olympus in both size and user interface flexibility.

Lens and Optical Performance: Zoom Range and Aperture

Compact cameras with fixed lenses are only as good as their optics - and here is where the two diverge distinctly.

The specifications:

Nikon’s 5× zoom starting wider (28mm) fits versatile framing needs - from moderate wide landscapes to short telephoto for portraits or street shots. Its macro capability impresses down to 1 cm, letting you fill the frame with tiny subjects with beautiful background separation thanks to decent optical stabilization.

Olympus offers a shorter 3× zoom range, less flexible but with a slightly brighter maximum aperture at the wide end (f/3.5). Macro focusing starts at 7 cm - less close than Nikon, meaning less dramatic close-ups.

Image stabilization differs too: Nikon utilizes true optical stabilization, which I found highly effective in minimizing handshake blur in low light or longer focal lengths. Olympus employs digital image stabilization, less effective and can degrade image sharpness.

In use, Nikon’s optics produced consistently sharper images, especially at the telephoto end where Olympus’s lens showed some softness. Chromatic aberration control and distortion correction were also better-calibrated in Nikon’s processor.

Autofocus and Shooting Responsiveness

One key differentiator in real-world shooting is autofocus (AF) system performance. Let’s see how each handles this critical feature.

Nikon’s S100 features contrast-detection AF with face detection and selective center-area focus. It offers continuous AF in live view, an uncommon feature for compacts of its release time. It also supports focus tracking on moving subjects.

Olympus 550WP relies on a simpler contrast-detection AF with no face detection and no continuous tracking; focus is locked on single shots.

From extensive hands-on testing with both cameras, Nikon’s AF is faster, more reliable, and versatile - especially important for capturing children, pets, or street subjects on the move. Olympus’s slower and less sophisticated AF often resulted in hunting or missed focus in low light or against complex backgrounds.

Continuous shooting on Nikon is modest but workable at 6 fps, good enough for casual bursts. Olympus does not specify burst rates, pointing to a less performance-focused design.

Two more subtle notes:

• Nikon supports touch AF (via touchscreen), enabling quick focusing on desired subjects.
• Olympus lacks touchscreen, so AF point selection is fixed and less flexible.

For action or spontaneity, Nikon offers an inherent advantage.

Image Stabilization and Low Light Handling

Optical vs digital stabilization has a clear impact:

• Nikon’s optical image stabilization (OIS) reduces blur from camera shake effectively, noticeable in zoomed shots and low light. This feature can widen your usable shutter speed range and improve sharpness without a tripod.
• Olympus was equipped only with digital stabilization, which relies on software cropping or frame blending and sometimes reduces image quality or field of view.

Testing indoors at 1/30s shutter speeds (typical handheld limit), Nikon images remained pin-sharp, Olympus showed softness and motion blur creeping in.

On high ISO sensitivity, Nikon’s CMOS sensor + Expeed processor excels. Images remain cleaner and more detailed at ISO 800 and can push to 1600–3200 with tolerable noise. Olympus’s CCD sensor from an earlier tech cycle struggles past 400 ISO with noticeable grain - limiting usefulness in dim environments.

These factors combine to give Nikon a clear edge for indoor, event, low light, and travel photography.

Video Capabilities Compared

Compact shooters often double as casual video tools; let’s see what they offer.

• Nikon Coolpix S100 records Full HD 1080p video at 30fps with MPEG-4 and Motion JPEG encoding options.
• Olympus Stylus 550WP maxes out at VGA (640×480) 30fps video, also in MJPEG format.

Practically speaking, Nikon delivers vastly superior video resolution and quality, suitable for casual home movies or social content capture.

Neither model features microphone or headphone ports, limiting advanced audio control, and lack in-body stabilization specifically for video.

Still, if short HD clips are essential, Nikon is the only choice here.

Specialty Features: Macro, Durability, and Connectivity

A few differentiators worth noting:

• Macro: Nikon’s 1 cm macro focus is impressive for a compact and genuinely satisfying in practice, producing strong background blur and close detail. Olympus’s 7 cm limit is less impactful.
• Weatherproofing: Olympus touts environmental sealing (though not waterproof), giving confidence in light rain or dusty conditions. Nikon lacks any sealing.
• Connectivity: Neither camera offers Wi-Fi, Bluetooth, or GPS - standard for this generation but a gap compared to today’s compacts.

Battery life when shooting stills is low on both (~150 shots Nikon); Olympus battery life specs are unavailable but likely comparable or shorter due to screen size and older tech.

Storage differs: Nikon uses the now-standard SD/SDHC/SDXC card, while Olympus supports xD-Picture Card and microSD, which may be a limitation regarding card availability today.
