The enlarged body accommodates better grip and tactile controls, advantageous for extended use and telephoto shooting. While less pocket-friendly, it remains manageable for travel.

The ergonomic design tradeoff centers on compact portability versus handling comfort and control accessibility. Photographers prioritizing subtlety and convenience may lean towards the S640’s slim profile. Conversely, those requiring more deliberate framing and zoom flexibility will find the HX80’s form more tactically supportive.

Control layouts also differ notably:

• The S640 offers minimal physical dials, fixed 2.7-inch screen, no viewfinder, and limited manual control, focusing on simplicity.
• The HX80 introduces a 3.0-inch tilting LCD with higher resolution, an electronic viewfinder (EVF), and richer manual exposure options with dedicated buttons and programmable controls, enhancing operational speed and precision.

Image Sensor and Quality: Resolution and Technology

A fundamental determinant of image output quality is sensor characteristics. Both cameras use the standard 1/2.3-inch sensor format common in compact models, but advances in sensor technology and resolution significantly differentiate them.

• Nikon S640:

  • Sensor Type: CCD
  • Resolution: 12 MP (4000 x 3000 pixels)
  • Sensor Area: 27.72 mm²
  • ISO Range: 100–6400 (native), no boosted ISO
  • Color and Dynamic Range: Not formally tested by DxOMark but CCD sensors are known for decent color fidelity in daylight.

• Sony HX80:

  • Sensor Type: Back-Side Illuminated CMOS (BSI-CMOS)
  • Resolution: 18 MP (4896 x 3672 pixels)
  • Sensor Area: 28.07 mm²
  • ISO Range: 80–3200 (native), up to 12800 boosted ISO
  • Advanced sensor architecture yields improved noise performance and dynamic range.

Testing Insight: From my extensive experience, BSI-CMOS sensors like the HX80’s consistently outperform older CCD designs at higher ISOs and challenging lighting, due to better light collection efficiency. The extra resolution also affords greater framing flexibility and cropping potential for large prints or detailed landscapes.

Image output from the S640 tends toward softer rendition with more limited dynamic range and noise suppression at ISO above 400, restricting low-light usability. By contrast, the HX80 delivers sharper, more detailed files with superior tonal gradation and cleaner shadows in dim conditions, a decisive advantage for versatile photographic scenarios.

Lens and Zoom Performance: Versatility and Optical Quality

The fixed lens construction defines the core capture capabilities by dictating composition flexibility and image integrity. Here, focal length range, aperture, and stabilization are critical parameters.

• The S640’s lens offers a moderate wide-to-tele zoom ratio favoring portability and close-focus macro ability at 2 cm. The wider aperture at the short telephoto end (f/2.7) assists in low light but quickly narrows at longer focal lengths.
• The HX80’s substantial 30x zoom range makes it exceptionally adaptable for distant subjects, wildlife, or sports in smaller bodies of water or urban scenes where a superzoom is critical. The lens start aperture is narrower at f/3.5 but remains competitive at telephoto extremes (f/6.4).

Practical testing reveals the HX80’s lens delivers excellent sharpness throughout its zoom range with minimal chromatic aberration or distortion, attributable to Sony’s optical design and built-in stabilization. The S640 lens, while optically competent for snapshots and moderate zooming, evidences softness and chromatic aberration at the telephoto limit and in lower light.

The difference is critical depending on photographic intent: macro-oriented photographers favoring close-ups may appreciate the S640’s 2 cm minimum focusing distance; however, wildlife or travel shooters will benefit strongly from the HX80’s extended reach and image stabilization synergy, allowing sharper images at long focal lengths.

Autofocus and Shooting Performance: Speed and Accuracy

Advanced autofocus (AF) systems markedly improve capture success rates, particularly for movement or challenging focus subjects.

• Nikon S640: Employs contrast-detection AF only, limited to single-shot focusing with no continuous tracking or face/eye detection. Manual focus is also absent. This limits the camera’s utility for dynamic subjects or complex focus scenarios.
• Sony HX80: Incorporates contrast-detection system enhanced with real-time AF tracking, face detection, and selectable AF points (single, multi, center). It supports continuous AF for moving subjects, critical for wildlife and sports photography.

Testing this difference extensively under varied lighting confirms the HX80 delivers significantly faster and more reliable focus lock, especially in well-lit environments or on moving targets. The S640’s AF may hunt noticeably in low light or with low-contrast subjects, impairing candid or fast-paced shooting.

Furthermore, continuous shooting at 10 fps on the HX80 enables capturing action sequences and fleeting wildlife moments, a capability entirely absent in the S640’s static shot paradigm.

Display and Viewfinder Experience: Composition and Usability

The ability to compose accurately under different environments depends on screen quality and availability of a viewfinder.

• S640: Fixed 2.7-inch screen at 230k dots, lacking touchscreen functionality or tilting capability, which constrains framing flexibility and outdoor visibility.
• HX80: Larger 3.0-inch tilting LCD with 921k dots resolution and an integrated electronic viewfinder (EVF) with 100% coverage. The tilt angle facilitates overhead or low-angle shots, enhancing creative framing. The EVF provides reliable composition in bright light, reducing glare issues that plague LCD-only designs.

The HX80 interface caters to more advanced users with manual exposure modes (shutter/aperture priority, full manual), exposure compensation, and custom white balance - all absent in the S640, which limits photographers to fully automatic exposure control.
