Panasonic FP2 vs Pentax S1: A Deep-Dive Comparison of Ultracompact and Small Sensor Compact Cameras

Choosing between two compact cameras, especially models like the Panasonic Lumix DMC-FP2 and the Pentax Optio S1, can be surprisingly nuanced. Both hail from reputable brands - Panasonic’s FP2 launched in early 2010 as a super-sleek ultracompact, while Pentax’s S1 arrived a year later as a slightly bulkier small sensor compact camera. At first glance, their specs might appear close, but spending hours testing and dissecting these two cameras reveals important distinctions that will shape how they perform in real-world photography scenarios.

Drawing on my extensive hands-on experience testing thousands of cameras, I’ll unpack the strengths and weaknesses of each - with a close eye on sensor tech, lens characteristics, autofocus, ergonomics, and overall user experience. This article offers a comprehensive comparison, grounded in practical use across photography genres, to assist enthusiasts and professionals in making an informed purchase based on their specific needs.

First Impressions: Size, Build, and Ergonomics

Starting with the fundamental question - how do these cameras feel in your hands, and what does their form factor say about usability and portability?

The Panasonic FP2 lives up to its ultracompact category. Its physical dimensions are an impressively slim 99 x 59 x 19 mm, weighing a mere 151 grams, making it exceptionally pocket-friendly. By contrast, the Pentax S1 tips the scales at slightly heftier 157 grams and measures 114 x 58 x 28 mm, reflecting its small sensor compact classification with a bulkier design. This difference might seem trivial on paper, but in daily use, the Panasonic’s sleek profile helps it disappear in your pocket during travel or casual street photography.

Examining the top control layouts reinforces their design philosophies. The FP2 opts for minimalistic controls with fewer physical buttons and a simple top plate - perfect for quick snaps but limiting manual intervention. The S1 offers a bit more tactile variability with slightly larger buttons and a traditional compact camera top layout, offering marginally better ergonomics for users who like physical feedback and quick adjustments.

Neither camera offers an electronic viewfinder, defaulting instead to fixed 2.7-inch LCD screens with identical 230k-dot resolution - a specification that feels dated under bright sunlight. The Pentax’s use of a TFT LCD with anti-reflective coating slightly edges out the FP2 in usability when shooting outdoors.

Ergonomic take: If ultra-portability is your top priority - say, for casual travel or street photography - the Panasonic FP2’s sleek profile wins. For users who appreciate a slightly larger, sturdier grip and more substantial controls, the Pentax S1 is preferable.

Sensor Technology and Image Quality: The Heart of the Matter

Both cameras feature 1/2.3-inch CCD sensors with around 14-megapixel resolution, a typical size and pixel density for compact cameras of this era. Sensor dimensions are remarkably close: 6.08 x 4.56 mm for the FP2 and 6.17 x 4.55 mm for the S1, with sensor areas differing by less than 1 mm².

CCD sensors, while excellent in delivering vibrant color and clean images at base ISOs in controlled light, have known limitations in high-ISO performance and dynamic range compared to more modern CMOS sensors. Both cameras max out at ISO 6400 (boosted) with a native low of ISO 80. However, neither raw file support nor extensive exposure controls are available, limiting post-capture editing flexibility for professionals.

Image quality highlights:

• Resolution and detail: Both can deliver respectable 14MP images, but the Pentax S1’s slightly larger sensor area can produce marginally crisper details. However, the difference in real-world sharpness is subtle.

• Noise and ISO performance: Both perform well up to ISO 400, but noise becomes very noticeable by ISO 800 and progressively worsens at higher settings. Given the lack of advanced noise reduction or raw capture, both are best confined to lower ISOs.

• Color and dynamic range: The CCD sensor’s color depth offers pleasant skin tones, especially for daylight portraits. Dynamic range is restricted to about 9 stops, typical for 1/2.3" CCDs – sufficient for casual shooting but less so for challenging landscape conditions.

Ultimately, neither camera challenges more modern compacts with larger CMOS sensors, but they deliver respectable JPEGs within their operational scopes.

Lens and Optical Performance: Zoom, Macro, and Stabilization

A camera’s fixed lens often defines its ultimate versatility. The Zoom range, aperture speed, and macro focusing distance can dramatically shape creative possibilities.

• Panasonic FP2: 35-140mm equivalent zoom (4×), max aperture f/3.5–5.9
• Pentax S1: Wider 28-140mm equivalent zoom (5×), slightly faster aperture f/3.5–5.5

The Pentax’s broader wide angle (28mm vs 35mm equivalent) is advantageous for landscapes and confined spaces - invaluable for travel or street photographers needing a wider field without stepping back.

Macro capabilities are where the Pentax S1 notably shines. Its minimum macro focus of just 1 cm from the front element sharply outperforms the FP2’s 10 cm minimum focusing distance, enabling true close-up shots with excellent detail - perfect for macro enthusiasts or those capturing fine textures.

Both cameras include optical image stabilization, but the implementation differs:

• The FP2 uses Optical stabilization, likely lens-shift based.
• The S1 features Sensor-shift stabilization.

In practice, sensor-shift systems (as seen in the S1) tend to be more effective across focal lengths and for video, offering steadier results when zoomed in or shooting handheld in low light, which aligns with my hands-on test observations.

This control over motion blur is especially important when combined with their slower lenses and modest maximum apertures, as it helps mitigate handshake in dimmer conditions.

Autofocus and Shooting Speeds: Capturing the Decisive Moment

AF systems largely determine how well cameras can capture sharp images, especially with moving subjects. Both cameras rely on contrast-detection AF with 9 focus points - standard fare for compact cameras in this category.

From testing, the Panasonic FP2’s AF felt nimbler, with a respectable 5 frames per second (fps) burst shooting speed. That’s quick enough for casual action or fleeting street scenes, although its single-shot AF means continuous AF tracking is absent. The FP2 also supports a live view AF mode, which is user-friendly.

The Pentax S1, in comparison, limits continuous shooting to just 1 fps, which curtails sports or wildlife utility significantly. Furthermore, its autofocus felt a touch slower to lock, particularly in low-light, although it boasts AF tracking capability, which is somewhat unusual for ultra-compact cameras of the time but undermined by its slow frame rate.

Neither camera supports sophisticated face or eye detection autofocus - something that’s understandable given their sensor and processing constraints but a disadvantage for portrait photographers seeking sharp critical focus on eyes.

Display and User Interface: Managing Your Shots and Playback

Each model sports a 2.7-inch LCD with 230k dot resolution - not in today’s league but functional. The Pentax S1’s anti-reflective TFT coating aids visibility in sunlight, a small yet significant advantage.

Neither model includes touchscreens or articulated displays, limiting flexibility in composing shots - something to keep in mind if you prefer shooting from odd angles.

Menus on both cameras are simplistic. The FP2’s interface is straightforward but minimalist, matching its ultracompact ethos. Meanwhile, the S1 provides a bit more by way of manual focus support, offering a physical ring control despite lacking full manual exposure - a rare feature worth noting given the compact size.

Video Capabilities: Basic Budgets for Casual Motion Shooters

Both cameras offer video in HD 720p resolution at 30 fps, encoded in Motion JPEG - a somewhat dated format that produces large files with limited compression efficiency.

• FP2: 1280 x 720 at 30fps
• S1: 1280 x 720 at 30 and 15 fps options, plus an HDMI output port, which the FP2 lacks.

Neither camera offers external microphone input or headphone monitoring, which restricts audio quality customization. Video stabilization is only sensor-shift on the S1, which yields steadier handheld footage.

For casual video clips - family moments or street scenarios - either camera suffices, but professional or semi-pro videographers will find both deficient in features and codec performance.

Durability and Battery Life: Will It Last?

Neither model includes rugged features like weather sealing or shockproofing, so users should treat them as delicate electronics rather than adventure-ready tools.

Battery life is officially specified only for the Pentax S1 at around 260 shots per charge using its proprietary D-LI92 battery pack. The FP2 lacks published battery life data, but anecdotal experience suggests a shorter endurance due to its smaller physical size - something important if you’re on a day trip without charging options.

Connectivity and Storage: Basics Without Wireless

Both cameras support SD/SDHC/SDXC cards, a useful feature given the increasing prevalence of large-capacity media at the time.

Connectivity is minimal:

• The FP2 offers USB 2.0 only.
• The S1 adds HDMI output for video playback.

Neither provides Wi-Fi, Bluetooth, NFC, or GPS - reflecting their generational context but a limitation for modern travel or geo-tagging needs.

Real-World Photography Test Gallery

To truly understand each camera’s mettle, I conducted exhaustive side-by-side shooting across diverse genres: portraits, landscapes, street, macro, and low-light scenarios.

Key observations:

• Portraits: Both deliver pleasing skin tones under daylight. However, the lack of face detection and eye autofocus means careful manual framing and focusing are required to get sharp eyes. The Pentax’s wider lens aids in environmental portraits, while the Panasonic’s faster burst can help capture fleeting expressions.

• Landscapes: The Pentax’s slightly wider 28mm equivalent lens and marginally better color rendering produce more compelling landscapes, but both show limited dynamic range. Cloudy or high-contrast scenes demand cautious exposure.

• Street: The Panasonic FP2’s slim form factor and fast responsiveness make it a stealthy street shooter. The Pentax’s bulkier design and slower autofocus means missed moments, though its superior macro lets it capture intriguing close-up street details.

• Macro: The Pentax S1’s min 1 cm focusing distance is a standout, capturing fine textures from flowers to small objects with precision unmatched by the FP2.

• Night/Astro: High ISO noise in both cameras is prohibitive for astrophotography. Neither entered my shortlist for night work beyond flash use.
