• 12 megapixels
• ISO range: 64–6400 (native)
• Includes anti-aliasing filter
• No RAW support

The S1H’s full-frame sensor is substantially larger than the W80’s tiny compact sensor. This translates directly into superior image quality, especially in low-light and high-contrast situations. In my testing, the S1H’s color depth and dynamic range were outstanding - critical for professionals requiring subtle gradations in skin tones or landscapes with challenging lighting. The wider ISO range also means you can push the camera’s sensitivity without excessive grain, ideal for night and astro photography.

The smaller sensor of the W80 inherently limits image quality. Noise becomes substantially visible above ISO 400, and dynamic range is constrained. While fine for casual daylight shooting and travel souvenirs, it won't deliver the rich tonality or flexibility desired by enthusiasts or professionals.

Autofocus Systems: Precision and Speed

Let’s talk autofocus (AF) - vital for capturing sharp images in unpredictable real-world conditions.

Panasonic S1H

• No AF bracketing or stacking

The S1H uses a sophisticated contrast-based system that, while not incorporating phase-detection points, performs very well thanks to intelligent AF algorithms tuned for video and stills. Eye detection is a boon for portrait photographers ensuring precise focusing on eyes without hunting. The camera’s face-detection is limited to humans; it lacks animal eye detection that competitors sometimes include.

In contrast, the W80’s autofocus is basic and slow by today’s standards. It’s optimized for stationary subjects in well-lit environments. The lack of continuous autofocus and face detection severely restricts its utility for fast-moving subjects like sports or wildlife.

Image Stabilization: Holding Steady When It Counts

The Panasonic S1H features 5-axis sensor-based image stabilization. I found this highly effective, providing 4–5 stops of stabilization, which allows shooting at slower shutter speeds hand-held with sharp results - a massive advantage in macro, landscape, and night photography.

The Pentax W80 has no image stabilization mechanism. Combined with its small sensor, this means blurred shots can crop up easily in low light or at long zoom settings unless a tripod or very steady hand is used.
