Sensor and Imaging Engine: Assessing Fundamental Image Quality

Both cameras employ a 1/2.3-inch CCD sensor with an equivalent diagonal sensor area of 28.07 mm², adhering to an industry standard for entry-level compacts at the time. Detailed sensor attributes influencing image quality include:

• Olympus TG-310:

  • Resolution: 14 megapixels
  • Maximum ISO: 1600 (native); no extended ISO available
  • Sensor type: CCD with anti-aliasing filter
  • Image processor: TruePic III+

• Sony W570:

  • Resolution: 16 megapixels
  • Maximum ISO: 3200 (native); no extended ISO noted
  • Sensor type: CCD with anti-aliasing filter
  • Image processor: BIONZ

Technical Analysis:

The Sony’s slightly larger pixel count (16MP vs 14MP) translates to a marginally higher maximum resolution (4608x3456 vs 4288x3216), which provides potential benefits for large prints or cropping flexibility. However, in practice, the increased resolution should be balanced against noise performance, particularly given the older CCD technology where pixel size reduction typically increases noise and lowers dynamic range.

Testing with standard scene charts and real-world samples indicated both cameras produce comparable image quality at base ISO (80-100), with moderate detail and color fidelity. The Olympus’s TruePic III+ engine prioritizes natural color tone reproduction with accurate skin tone rendition, while the Sony’s BIONZ processor delivers slightly more vibrant colors, albeit sometimes oversaturated for neutral reproduction purists.

The Sony W570’s ISO range extends to 3200, but high ISO images show increased chroma noise and loss of detail above ISO 800. The Olympus TG-310 is more conservative, maxing out at ISO 1600 with noise levels rising noticeably above ISO 400. Neither camera offers RAW support, limiting post-processing flexibility; shooters must rely on JPEG outputs, which include in-camera noise reduction and sharpening.

As both use CCD sensors - less adept than modern CMOS units at high sensitivity performance - expect limited low-light capabilities. However, the Sony’s ISO advantage and optical stabilization might provide a slight edge in challenging lighting.

Lens Characteristics and Autofocus Performance

Lens configuration fundamentally shapes photographic versatility and image quality.

• Olympus TG-310:

  • Focal range: 28-102 mm equivalent (3.6x zoom)
  • Maximum aperture: F3.9–5.9
  • Macro focus: down to 3 cm
  • Stabilization: Sensor-shift image stabilization
  • Focus system: Contrast detection AF with face detection; AF tracking available

• Sony W570:

  • Focal range: 25-125 mm equivalent (5x zoom)
  • Maximum aperture: F2.6–6.3
  • Macro focus: down to 5 cm
  • Stabilization: Optical SteadyShot (OSS)
  • Focus system: Contrast detection AF on 9 points; no face detection or AF tracking

Both cameras utilize fixed, non-interchangeable lenses. The Sony W570’s lens offers a longer zoom reach and wider widest aperture (F2.6) compared to Olympus’s often slower maximum aperture at the telephoto end. This results in better potential low-light and background separation performance on the Sony at wide angles. However, the Olympus lens starts closer (28mm vs 25mm), delivering virtually the same wide-angle capability but with a shorter zoom range.

In practical autofocus testing, the Olympus TG-310 benefits from active face detection and AF tracking modes, enhancing portrait and casual shooting success in dynamic scenes. The Sony’s 9-point AF array performs adequately but lacks the more sophisticated subject tracking features found in Olympus.

Macro capability favors the TG-310 with a minimum focusing distance of 3 cm versus Sony’s 5 cm, allowing closer detail captures. Additionally, sensor-shift stabilization in the Olympus generally yields steadier macro shots compared to Sony’s OSS optical lens stabilization.
