Nikon Coolpix S31 vs Olympus Stylus 550WP: A Comprehensive Comparison for Photography Enthusiasts

When evaluating compact cameras, especially models targeted toward enthusiasts who appreciate ruggedness and portability, it’s essential to take a hands-on approach that goes beyond specs. I’ve tested hundreds of compact cameras, scrutinizing sensor performance, ergonomics, autofocus, and real-world usability across multiple shooting scenarios. Here, I compare two compact waterproof-sturdy cameras: the Nikon Coolpix S31 and the Olympus Stylus 550WP. Both aim to serve photographers seeking durability, but their design philosophies and capabilities cater to different needs.

This detailed comparison spans portrait, landscape, wildlife, sports, street, macro, night, video, travel, and professional photography. By the end, you’ll understand which camera better aligns with your shooting style and expectations.

First Impressions: Build, Size, and Handling

The Nikon Coolpix S31 and Olympus Stylus 550WP are sold under the premise of “tough cameras” for outdoor use, but their physical designs tell distinct stories:

• Nikon S31: Larger and chunkier (105 x 65 x 42 mm; 185g), with a robust waterproof, dustproof, freezeproof, and shockproof body. The thicker body provides a solid grip, which is helpful for active users or outdoor environments. It features straightforward controls aimed at simplicity, presumably to appeal to families or casual shooters wanting ruggedness without complexity.

• Olympus Stylus 550WP: Smaller and slimmer (94 x 62 x 22 mm; 167g), the camera trades some rugged features for portability and convenience. It’s still weather-sealed but lacks the shockproof or freezeproof certifications of the Nikon. It is less bulky and easier to slip into a pocket or bag.

Handling-wise, the S31 favors durability at the expense of compactness, while Olympus emphasizes ease of carry with fewer rugged assurances. For travel enthusiasts balancing protection with space, this contrast is crucial.

Design and Control Layout: User Interface of Tough Cameras

Both cameras skip traditional viewfinders and offer fixed 2.5-2.7" TFT LCDs with 230k-dot resolution. Without touchscreens or articulated displays, user interaction relies on physical buttons.

• Nikon S31: Button placement is minimalistic but large enough to operate with gloves - ideal for harsher weather. The lack of customizable controls or manual modes keeps operation simple but limits creative flexibility. There’s no exposure compensation or manual focus.

• Olympus 550WP: Slightly more versatile, it provides exposure modes and a self-timer function, embracing a bit more control, though it still lacks manual focus or priority modes. Image stabilization is digital rather than optical but is present. Buttons are compact, fitting the slimmer body but may be harder to use with gloves.

For photographers who want quick, no-fuss point-and-shoot operation, S31’s layout is compelling. For those who appreciate a few more in-camera options, 550WP offers a modest edge.

Sensor and Image Quality: CCD Technology in Compact Cameras

Both models use 1/2.9" (Nikon) and 1/2.3" (Olympus) CCD sensors with a maximum resolution of 10 megapixels.

Key differentiators:

• Olympus 550WP’s sensor is larger (27.72 mm² vs 18.45 mm² on Nikon), which usually translates to better low light performance and greater detail retention.
• Both offer ISO up to 1600 but neither supports RAW, limiting post-processing flexibility.

From my tests in controlled environments:

• Nikon S31’s images have adequate detail under bright lighting but suffer in low light with more noise and less dynamic range.
• Olympus’s slightly larger sensor yields marginally better noise control and slightly improved color accuracy, especially in shadows and highlights.

Neither camera challenges modern standards for image quality but, for casual usage, Olympus edges out Nikon by a small margin. Portraits taken with the Olympus show better skin tone fidelity and more natural colors.

Autofocus and Shooting Speed: Catching the Moment

Neither camera is designed for speed or focus precision expected in professional cameras. They drop advanced AF modules, relying on contrast detection autofocus only.

• Nikon S31 has no face detection or continuous AF features, which can result in hunting focus and struggling in low contrast scenes.
• Olympus 550WP features contrast detection AF with center-weighted metering and spot metering options, allowing a bit more precise lock but no face detection.

Neither supports burst shooting, and their shutter speed range is limited (Nikon: 4–1/2000 sec, Olympus: 4–1/1000 sec).

In real life, for fast-action genres like wildlife or sports, both cameras fall short due to focus sluggishness and lack of frame rates. Street and travel photographers may find Olympus’s marginally faster and more reliable AF better suited for spontaneous moments.

Durability and Environmental Sealing: Ruggedness Verified

This is where these cameras differ the most:

• Nikon Coolpix S31: Waterproof to 10 meters, shockproof from 1.2 meters, freezeproof to -10°C, and dustproof. This rugged package protects the camera from typical outdoor hazards.
• Olympus Stylus 550WP: Waterproof to 3 meters and weather-sealed, but not shockproof or freezeproof.

If your work or hobby takes you to risky environments like hiking, skiing, or beachside settings, the Nikon clearly offers peace of mind with higher durability specifications.

Display, Viewfinder, and Interfaces: What Are You Looking At?

Both cameras lack optical or electronic viewfinders, relying solely on fixed LCDs. The screens offer minimal resolution, with no touch capabilities.

Practically speaking:

• The Nikon’s larger screen (2.7") helps better composition during active shoots.
• Olympus’s smaller 2.5" screen suffices for casual framing but may be harder to see under direct sunlight, a weakness for outdoor use.

Connectivity is basic on both: USB 2.0 only, no Wi-Fi, Bluetooth, or NFC. For photographers nowadays expecting seamless image transfer, both are behind the curve.

Lens and Zoom: Reach and Versatility

Each camera is fitted with a fixed zoom lens:

• Nikon S31: 29–87 mm equivalent (3x zoom), with a 7.3x focal length multiplier.
• Olympus 550WP: 38–114 mm equivalent (3x zoom), aperture range f/3.5–5.0, 5.9x multiplier.

The Olympus’s lens starts at a longer focal length, offering slightly better telephoto reach but missing wider angles useful for landscapes or tight interiors.

Neither lens offers macro focusing beyond typical close focus distances, but Olympus can focus as close as 7cm, better for casual macro shots.

Image stabilization in Olympus is digital only, lacking the effectiveness of optical IS. Nikon provides none.

Video Capabilities: Beyond Still Photography

Video recording is basic on both:

• Nikon S31 records HD 720p at unspecified frame rates.
• Olympus 550WP maxes out at VGA 640x480 resolution at 30fps in Motion JPEG format.

Neither supports modern HD or 4K video standards, lacks microphone inputs, and offers no continuous autofocus during video.

If video is a secondary but important feature in your camera, neither is ideal. For casual clips, Nikon’s HD framing might please you more, but the Olympus’s limited resolution and format mean the videos won’t age well.

Battery Life and Storage: How Long and What Fits?

• Battery life: Nikon S31 claims about 260 shots per charge. Olympus does not specify clearly but likely similar and possibly lower given smaller body.
• Storage: Nikon uses standard SD/SDHC/SDXC cards; Olympus uses now-obsolete xD Picture Card format along with microSD and internal memory.

The Nikon’s SD card compatibility eases workflow and storage expansion, while Olympus’s xD cards are less common and can be a logistical hurdle.
