Despite their similarities in form factor and market positioning, subtle differences in their sensor systems, optics, ergonomics, and feature sets reveal distinctive strengths and compromises that can influence user experience and image output.

Drawing from my extensive firsthand testing encompassing sensor analysis, autofocus evaluation, and real-world shooting across multiple photography genres, this article presents an authoritative, exhaustive comparison of these two compact shooters. It is designed to guide enthusiasts and professionals alike - whether upgrading from smartphone photography or hunting for a secondary travel companion - toward a smart purchase choice rooted in detailed knowledge and practical insight.

First Impressions and Physical Ergonomics: Fit in Your Hand and Pocket

Starting with the tactile feel and handling, both the Nikon S3100 and Sony W510 fall firmly into the ultracompact category. They share nearly identical display sizes (2.7 inches) and feature fixed-lens designs that prioritize portability.

• Nikon S3100: Measuring approximately 94x58x18 mm and weighing just 118 grams (battery included), the S3100 boasts slimness and a flat profile, which allows it to slip comfortably into pockets yet remains stable during handheld operation. The body utilizes a modestly textured finish that enhances grip without detracting from its sleekness.

• Sony W510: Slightly shorter and wider at 96x54x20 mm, the W510 weighs a nearly identical 119 grams. Its distinctly rounded edges and slightly more rounded profile provide a different ergonomic feel - favoring those who prefer a softer grip contour, though the extra thickness may be noticeable in particularly tight pockets.

In practical daily use, both cameras remain eminently portable, with neither significantly outshining the other. However, the Nikon’s flatter chassis may appeal more to users prioritizing shove-in-and-go convenience, whereas the Sony’s balanced contour supports steadier handling for slightly longer shooting sessions.

Design, Control Layout, and User Interface: Intuitive Operation in a Simple Package

A camera's control scheme and interface design significantly influence how quickly users can adapt and maintain shooting flow - a consideration where subtle differences can matter.

• Nikon S3100: The top view reveals an ergonomically placed shutter button with a textured zoom rocker surrounding it, facilitating intuitive thumb operation. Controls are minimal, supporting a clean face without overwhelming buttons. On the rear, the absence of a system dial or manual exposure buttons signals its focus on simplicity.

• Sony W510: Sony opted for a comparably minimalistic approach but integrates a slightly more protruding zoom toggle and a well-sized shutter release button. The rear houses a straightforward four-way controller with a central "play" button, streamlining navigation but limiting direct access to advanced functions.

While neither camera supports manual exposure or aperture/shutter priority modes, their menus are streamlined and accessible. The Nikon’s Expeed C2 processor contributes to a responsive live view, whereas Sony’s BIONZ engine delivers similarly snappy operation.

Users transitioning from smartphones or first-time digital camera buyers will appreciate the modest learning curve both cameras offer. Slight ergonomic preferences will vary individually, but overall, both are commendably optimized for entry-level users.

Sensor Technology and Image Quality: Insights from the CCD Battlefield

One of the most critical technical factors is sensor performance, which underpins image quality, dynamic range, noise characteristics, and output resolution.

1/2.3-inch CCD sensors, ubiquitous in compact cameras of this era, serve as the imaging heart for both models, yet with notable differences:

The Nikon edges out slightly with a higher megapixel count (14MP vs 12MP), which on paper translates to increased detail capture potential, especially relevant for prints or cropping flexibility. However, higher pixel density on a small sensor can exacerbate noise, so pixel pitch and noise suppression strategies come into play.

Testing under both studio and natural lighting conditions revealed the Nikon S3100 manages sharper images with somewhat richer colors but shows marginally more susceptibility to noise at ISO 800 and above. Conversely, Sony W510 benefits from sensor-shift image stabilization, allowing for steadier shots that mildly mitigate noise by enabling slower shutter speeds. The Sony’s images demonstrate slightly smoother gradations, with diminished noise patterns in low light despite the lower resolution.

Neither camera supports RAW capture, limiting post-processing latitude - common in this class but a notable constraint for advanced users.

For applications emphasizing maximum resolution and detail (landscape cropping, casual portraiture), the Nikon’s sensor is advantageous. For shutter speed flexibility and handheld low-light scenarios, the Sony’s stabilization lends a real-world benefit.

LCD Screen and Viewfinder: Visual Composition and Feedback

Both cameras omit electronic viewfinders, directing composition through their LCD screens exclusively - a common compromise in ultracompacts given size constraints.

• Nikon S3100: Features a 2.7-inch TFT LCD with a resolution of 230,000 dots. The screen, while modest by modern standards, offers acceptable brightness and contrast in normal indoor lighting but struggles visibly under strong sunlight without shading.

• Sony W510: Matches the screen size and resolution but uses a "Clear Photo LCD" technology, designed to enhance clarity and color vibrancy. In practice, this yields marginally better readability outdoors and slightly richer interface colors.

Neither screen offers touchscreen input, and both favor simplicity over configurability. The lack of any electronic or optical viewfinder can hinder composition precision in bright environments but aligns with the size and price constraints.

For users who habitually shoot outdoors or require precise framing, the Sony’s screen holds a slight edge. However, for indoor and casual handheld shooting, both suffice for framing and image review.

Lens and Optical Performance: Aperture, Zoom Range, and Macro Capabilities

A fixed lens system defines these cameras, with focal lengths offering versatility for everyday subjects.

The Nikon offers a slightly longer telephoto reach, useful for capturing more distant subjects, but with narrower aperture at the long end which affects low-light ability and depth of field control.

In contrast, the Sony begins at a brighter f/2.8 aperture on the wide end, which supports better background separation and indoor shooting without flash - valuable for portraits and ambient-light scenarios. Its shorter telephoto maximum sacrifices some reach but maintains better maximum aperture, favorable for general-purpose use.

The Sony’s 4 cm macro focusing excels compared to Nikon’s 10 cm minimum focusing distance, enabling more intimate close-ups with richer detail - great for macro enthusiasts or creative close-range shooting.

Presence of sensor-shift image stabilization on the Sony is a critical advantage when shooting telephoto or macro handheld; the Nikon lacks this entirely, relying more on flash or high ISO.

Autofocus and Shooting Speed: Rapid Response Versus Steady Precision

Autofocus (AF) systems and shooting speed underpin usability, especially for capturing fleeting moments or moving subjects.

Both cameras employ contrast-detection AF systems common for ultracompacts, with 9 focus points providing moderate coverage. However, the Nikon’s inclusion of face detection and basic tracking differentiates it by improving reliability for portrait and family snapshots.

Neither camera supports continuous autofocus, limiting action photography capabilities. Burst shooting is similarly slow (1 fps), relegating both cameras to casual stills rather than sports or wildlife fast action.

For applications reliant on accurate face-based AF such as portraits or social events, Nikon's advantage is apparent. Sony’s system, while competent, may require more manual patience to lock focus.

Flash and Low Light Performance: Versatility When Light is Scarce

Both models include built-in flash units differing slightly in range and modes:

• Nikon S3100: Flash range up to 4.5 meters with Auto, On, Off, and Red-Eye Reduction modes, offering useful fill flash capabilities for portraits and indoor use.

• Sony W510: Lower flash range at 2.3 meters but incorporates Slow Sync flash mode, enhancing low-light ambient capture by slowing shutter speed while illuminating the subject - valuable for natural-looking images in dim conditions.

In testing, Nikon’s longer flash reach provides more flexibility in larger rooms or moderate daylight fill, while Sony’s Slow Sync flash offers controlled background exposure for atmospherics but with reduced effective illumination distance.

Video Capabilities: HD Quality and Usability for Casual Filmmakers

Video functionality often distinguishes entry compacts for hybrid shooters who want both still capture and video recording.

The Nikon offers superior HD video resolution (720p), a significant advantage in an era when HD video was an emergent standard among compact cameras. This makes it a better choice for users seeking casual yet watchable video clips.

Sony records at VGA (640 x 480), which by 2011 standards felt dated and limits practical use for video-centric projects. The lack of microphone inputs and advanced exposure controls on both models reflects their simple consumer orientation.

Image stabilization during video on Sony makes handheld footage slightly less jittery despite lower resolution, but overall, Nikon’s higher definition output has greater long-term value.

Battery Life and Storage Options: Practical Considerations for Day-to-Day Use

• Nikon S3100: Uses the proprietary EN-EL19 battery pack; rated for approximately 220 shots per charge under CIPA testing standards - modest but typical for the class.

• Sony W510: Utilizes NP-BN1 battery, with manufacturer details less clear but generally comparable endurance.

Both models accept SD/SDHC/SDXC cards, with Sony also compatible with Memory Stick variants, expanding media card options. Neither camera supports dual card slots or external battery grips, reinforcing their casual design.

Photographers anticipating longer shooting sessions, trips, or events should consider spare batteries, as these ultracompacts do not boast extensive endurance.

Build Quality and Environmental Sealing: Durability in Various Conditions

Neither camera offers environmental sealing, weather resistance, or shock-proof certification. This is standard for ultracompacts in this price range but means users must handle with care outdoors, in damp conditions, or in rugged scenarios.

The Nikon and Sony bodies are well-assembled and robust for daily handling, but expect plastic construction without magnesium alloy components found in higher-tier cameras.
