Sensor and Image Quality: Resolving Power, Color, and Noise Handling

Image quality starts with the sensor - its size, resolution, and technology dictate detail capture, dynamic range, and noise performance.

Sensor Technologies and Resolution

Both cameras employ a 1/2.3" CCD sensor, a common small sensor standard in compact cameras, but with notable differences:

• Panasonic TS25: 16-megapixel resolution (4608 x 3456 pixels), max ISO 6400.
• Pentax W80: 12-megapixel resolution (4000 x 3000 pixels), max ISO 6400.

The TS25's higher megapixel count theoretically offers greater detail but can be sensitive to noise due to pixel density. The W80’s fewer pixels mean larger individual photodiodes, generally better for light gathering and image quality at higher ISOs.

Color Depth, Dynamic Range, and Noise

Though neither camera has been DxOMark tested, practical testing revealed the TS25 produces more vibrant colors with Panasonic’s known processing style, especially in daylight. The W80 displays slightly muted but natural colors with less oversaturation.

Dynamic range is limited on both, typical of compact CCD sensors, with highlight clipping visible under high contrast scenes. Shadow detail preservation is average, better at ISO 100–200.

Regarding noise performance, both cameras struggle beyond ISO 400 due to small sensor size but:

• The W80’s sensor yields cleaner images at ISO 400-800.
• The TS25 introduces heavier noise and softness past ISO 400 but offers optical image stabilization which aids in lower ISO captures and slower shutter speeds.

Lens Quality and Aperture

• Panasonic's 25-100 mm equivalent lens has a max aperture of f/3.9–5.7.
• Pentax offers 28-140 mm equivalent with a slightly faster max aperture of f/3.5–5.5.

The W80's lens offers a broader zoom range with a closer macro focusing distance of 1 cm versus 5 cm for the TS25, enabling more detailed close-up shots.

LCD and Viewfinder: Usability and User Interface

Both lack electronic or optical viewfinders, relying on rear LCD screens for composition.

• Panasonic TS25 sports a 2.7-inch TFT LCD with 230k dots.
• Pentax W80 has a 2.5-inch fixed LCD with the same resolution.

The TS25’s slightly larger screen provides more comfortable framing and reviewing images. Both screens fare well in daylight with decent brightness but are limited by low resolution and narrow viewing angles typical for their era and price.

Neither camera has touchscreen capabilities, so navigation relies on physical buttons - which are responsive but basic.

Autofocus, Exposure, and Performance: Speed and Accuracy

The cameras diverge noticeably here despite similar class positioning.

Autofocus Systems

• Panasonic TS25: Contrast-detection system with 23 focus points and face detection.
• Pentax W80: Contrast-detection with 9 points, no face detection.

In testing, the TS25 autofocus locked quicker and more consistently on faces and subjects in daylight and moderate indoor lighting. The W80 occasionally hunted but performed adequately for casual shooting.

Continuous AF is only possible on the TS25, though limited performance means neither camera excels for moving subjects.

Shutter Speeds and Burst Rates

• Shutter range TS25: 8–1/1300 sec.
• Shutter range W80: 4–1/1500 sec.

Neither offers manual exposure control, aperture, or shutter priority modes, limiting creative flexibility.

Continuous shooting:

• TS25 records 1 fps (frames per second).
• W80 limited to single-frame capture only.

For sport or wildlife photographers needing fast action capture, both are underpowered and best suited for static or slow-moving subjects.
