Both cameras lack any weather sealing, dust, or shock resistance, limiting their use in rugged outdoor settings. Their plastic construction is standard for the entry-level compact class, with the Nikon’s larger body affording a sturdier feel. Neither model is designed with professional-grade reliability in mind, which impacts use in prolonged professional workflows requiring resilience.

Sensor and Image Quality: Evaluating the Heart of the Camera

Both cameras employ a 1/2.3-inch sensor measuring 6.17 x 4.55 mm with a sensor area of 28.07 mm². This small sensor size constrains dynamic range and noise control capabilities, common in compact cameras.

• Nikon Coolpix S9100: Utilizes a 12 MP backside-illuminated (BSI) CMOS sensor. BSI architecture enhances light gathering efficiency, granting the S9100 an advantage in low-light sensitivity compared to traditional frontlit sensors.

• Sony DSC-W730: Employs a 16 MP CCD sensor, a technology with older architecture, generally less efficient in noise control and dynamic range but often yielding slightly sharper detail rendition due to different image processing pipelines.

Resolution and Detail Reproduction

In controlled testing, the Sony’s 16 MP resolution translates to theoretically higher resolving power, evident when viewing JPEGs at 100% crop, provided good lighting. However, the Nikon’s BSI CMOS sensor delivers cleaner images with less luminance noise at higher ISOs, which is crucial for shooting in ambient or indoor lighting without a tripod.

High ISO & Noise Performance

Both cameras have a maximum ISO of 3200 native, but the practical usability of these settings diverges. The Nikon’s sensor and the Expeed C2 processor yield cleaner images at ISO 800 and 1600, with less chroma noise and better detail retention, whereas the Sony’s CCD sensor produces noticeably grainier images beyond ISO 400, making higher ISOs less usable in practice.

Color Rendition and White Balance

Custom white balance is supported on both, aiding color fidelity in mixed lighting. Nikon employs a color science that renders natural, balanced skin tones and faithfully reproduces foliage greens - important for portraiture and landscapes. Sony’s color rendition tends to be slightly oversaturated, appealing for vibrant scenes but sometimes compromising natural realism.

Lens and Zoom Capability: Versatility Versus Reach

The Nikon’s 18× zoom lens stands out decisively, ranging from wide-angle 25mm to a super-telephoto 450mm equivalent, which facilitates capturing subjects that are distant or require extreme framing flexibility - valuable for wildlife or sports shooters on a budget.

Conversely, the Sony’s 9× zoom (25-224 mm equivalent) offers moderate telephoto reach, suitable for everyday walks or casual portraiture but limited for action or wildlife.

The Nikon’s wider aperture at the tele end (f/5.9 vs. Sony’s f/6.3) allows marginally better light intake when zoomed in, though both telephoto apertures are narrow for optimal background separation or bokeh.

Focusing as close as 4 cm on the Nikon compared with 5 cm on the Sony places the Nikon slightly ahead in macro photography potential, where focusing precision and proximity reveal fine detail. Sturdier sensor-shift stabilization in the Nikon is also advantageous at long focal lengths to mitigate handshake compared to Sony’s optical system.

Autofocus and Shutter Performance: Speed and Accuracy under Pressure

Autofocus System

• Nikon S9100: Uses a 9-point contrast-detection autofocus system, supports face detection, and offers AF tracking to follow moving subjects. Manual focus is available, a rarity in this class.

• Sony W730: Also employs contrast-detection AF with unspecified focus points, face detection included, but lacks manual focus capability and has slower AF performance due to older hardware.

Tests show the Nikon’s autofocus acquires and locks more swiftly and accurately than the Sony, particularly in lower light and continuous AF tracking of moving subjects. The Nikon’s enhanced AF tracking capability benefits sports or wildlife photography scenarios where subjects are unpredictable.

Shutter Speed and Burst Modes

Nikon S9100 supports a shutter range of 4 to 1/2000 seconds and can sustain a continuous shooting speed of 10 frames per second (fps), which is exceptional for entry-level compacts. This enables more chances to capture fast action sequences.

Sony W730 offers slower shutter options from 2 to 1/1600 seconds and a modest single shot per second continuous mode, insufficient for capturing rapid sequences cleanly.

This combination decisively tips the scale to Nikon for action, wildlife, or sports photographers needing responsive capture.

Screen and Viewfinder Experience: Composing and Reviewing Images

Neither camera includes a dedicated viewfinder, requiring reliance on the rear LCD for framing. The Nikon’s 3-inch 921k dot TFT with anti-reflection coating provides excellent clarity and color accuracy, improving framing precision under sunny outdoor conditions.

The Sony’s 2.7-inch 230k dot LCD touchscreen is less detailed and more reflective, potentially complicating composition outdoors. The touchscreen’s responsiveness is adequate but not ideal for fast operation, compounded by a smaller screen size.

From a practical usability standpoint, the Nikon’s screen greatly improves situational awareness and image review, critical for street and travel photography where quick verification is beneficial.

Video Capabilities: Moving Images and Multimedia Functionality

The Nikon S9100 supports Full HD 1080p recording at 30 fps, a notable advantage over the Sony’s maximum 720p HD resolution. Nikon’s sensor-shift stabilization during video recording reduces shake, producing steadier footage without auxiliary gear.

The Sony’s optical stabilization helps but the lower resolution diminishes output quality. Neither camera offers external microphone or headphone connectivity, limiting audio control, which is standard at this price point.

Hence, for users focusing on casual video recording, the Nikon provides higher-quality moving images, better stabilization, and more flexible post-production options.

Battery Life and Storage: Practical Photography Concerns
