Conclusion: People need inexpensive and adequate digital cameras, and Pentax produced the Optio S1 to meet that need. There’s nothing revolutionary or mind blowing about its technology, but it is easy to use and takes decent to above-average photos, if you’re willing to learn a little and use manual settings where you can.
Pros: Simple, clean design, Easy to use, Built-in editor, filters are great for entry-level shooters
Cons: Noisy above ISO 800, Poor low-light performance
Summary: The Pentax Optio S1 is small, affordable and doesn't skimp on the specs. Picture quality isn't spectacular but those looking for a simple, stylish compact in the sub-£100 price bracket should definitely give it a shot.
Pros: Small, slim design; easy to use; 5x optical zoom; good value.
Cons: Some picture issues; poor video quality; small buttons.
Summary: The Pentax Optio S1 brings together a capable zoom range and user-friendly features inside a tiny body, and in fine lighting conditions it can record noise-free images with good detail and colour. Sadly, image quality is let down by an unpredictable Auto White Balance system and plenty of softness in the corners of the frame.
Pros: Small, competitively priced, stylish next to many of its peers, brisk operation, good exposures
Cons: Unattractive plastic covering, white balance issues, corner softness, prone to flare
Excerpt: The average person shopping for a £100 camera probably just wants three things: a brand they've heard of, a high megapixel rating and a smart design. Pentax's latest budget snapper ticks all those boxes, but it also includes a few features to impress more discerning shoppers. There's optical stabilisation built into the sensor, which allows slower shutter speeds in low light without succumbing to camera shake.
