Sensor Architecture and Image Quality Fundamentals

Sensor technology remains the cornerstone of image quality potential, encompassing resolution, size, and sensor type. A rigorous evaluation of these factors under controlled lighting and standardized ISO settings was conducted.

• Sensor Size and Type
  The P80 features a 1/2.3" CCD sensor (6.17x4.55mm, 28.07 mm²), while the HX5 employs a slightly smaller 1/2.4" BSI-CMOS sensor (6.104x4.578mm, 27.94 mm²). While the difference in physical sensor area is marginal, the underlying sensor technology affects photon efficiency and noise characteristics.
  
  The CCD in the P80 is typical of cameras from its era - imparting relatively low noise at base ISO but increasing susceptibility to read noise and lower dynamic range at higher sensitivity settings. Sony’s BSI-CMOS sensor in the HX5 leverages backside illumination to enhance low-light performance and dynamic range, which translates into cleaner high ISO images and improved color fidelity in shadow areas.

• Resolution and Native ISO
  The P80 sported 12MP resolution (4000x3000 max) with a native ISO range of 64–6400, whereas the HX5 offers 10MP (3456x2592 max) at ISO 125–3200. In practice, the slight resolution advantage of the P80 does not compensate for its higher noise in elevated ISO levels, whereas the HX5’s sensor trades a small amount of resolution for superior noise control and richer tonal gradation.

Optics and Zoom Performance across Use Cases

Lens characteristics heavily influence compositional flexibility and image aesthetics. Zoom range, aperture breadth, and focal length multiplier together provide a comprehensive lens performance profile.

• Focal Length and Aperture Range
  The P80’s 28-110 mm equivalent (4x zoom) with variable max aperture f/2.6–5.8 provides a modest telephoto reach suitable for everyday framing but limited in wildlife or sports contexts. The HX5, by contrast, offers an expansive 25-250 mm equivalent (10x zoom) with f/3.5–5.5 aperture, facilitating more diverse compositions from wide landscapes to distant subjects.

• Macro Focus Capability
  Close-up shooting reveals the HX5’s superior macro capacity with a 5 cm minimum focusing distance versus the P80’s 10 cm. This advantage, combined with the HX5’s optical image stabilization (OIS), permits sharper hand-held close-ups - a critical feature for macro or product photography. The P80’s lack of stabilization imposes shutter speed constraints and elevates the risk of blur in these scenarios.

Autofocus Systems: Speed and Accuracy Under Pressure

Autofocus (AF) performance is paramount in fast-paced photography such as wildlife and sports. Both cameras utilize contrast-detection AF systems with 9 focus points, but operational differences are consequential.

• AF Modes and Face Detection
  Neither model supports advanced AF refinements such as face or eye detection, limiting their efficacy for portrait applications demanding precise facial focusing. The HX5 offers center-weighted AF as standard and supports multi-area AF to improve subject acquisition, whereas the P80’s AF is more rudimentary without multi-area or select AF area controls.

• AF Speed and Continuous Shooting
  The P80’s single AF system and slower shutter speed range (4s to 1/1000s) hamper its effectiveness in dynamic environments. Continuous shooting maxes out at 3 fps, insufficient for tracking fast action. The HX5 significantly improves on this, delivering 10 fps bursts and a max shutter speed of 1/1600s, coupled with faster AF acquisition - benefiting sports and wildlife photographers.

Image Stabilization and Exposure Control

Stabilization and exposure versatility directly influence image sharpness and creative control.
