Panasonic Lumix DMC-S2 vs Pentax Optio H90: A Hands-On Comparison of Two Compact 1/2.3” Sensor Cameras

In the crowded world of compact cameras, especially those armed with modest-sized 1/2.3" sensors, choices often boil down to nuanced differences rather than headline-grabbing specs. Today, I’m delving deeply into two contenders from the early 2010s aimed at casual shooters and enthusiasts hoping for a blend of simplicity, decent image quality, and pocket portability: the Panasonic Lumix DMC-S2 and the Pentax Optio H90. Both share a similar category but approach imaging with different emphases.

Over many hours testing and direct comparisons, I’ve evaluated these cameras through the lens of photographic disciplines and real-world use - providing an honest, pragmatic assessment that can help you decide which camera might fit your own shooting style and budget.

Size, Ergonomics & Handling: The Interface That Stays With You

Before reaching for specs, the first impression you get from a camera is how it feels in your hands and pockets. Handling can hugely impact your shooting comfort, especially for a camera not meant to be a burden but your go-to grab-and-shoot companion.

Here, the Panasonic S2 measures a slight 98 x 57 x 21 mm and weighs a featherlight 112g (battery included). The Pentax H90 is visibly chunkier at 101 x 65 x 28 mm, tipping the scales to 153g. The difference isn’t just about numbers - the S2’s slimmer, lighter design makes it notably pocket-friendlier and less fatiguing for spontaneous shooting during travel or street photography.

The Pentax H90, on the other hand, feels more substantial and solidly built in hand - though not by a huge margin. The added heft translates to a more confident grip but sacrifices some stealth and compactness.

Both cameras lack an electronic viewfinder, relying strictly on LCD composition, which I admit limits options in bright conditions but is typical of this class.

Controls & Layout: Less Is More?

Examining the top plate closely, Panasonic’s control layout is intuitive but bare-bones with minimal dedicated dials or buttons - typical for the S2’s fixed-lens compact ethos. The absence of manual exposure modes or shutter-priority limits creative control but keeps operation straightforward for novices.

The Pentax H90 incorporates slightly more tactile controls, including manual focus and face detection toggles, reflecting Pentax’s attempt to appeal to users demanding a bit more versatility in focusing options.

Notably, the H90 includes a sensor-shift image stabilization system - a technical edge over the S2’s optical stabilization but more on this later.

Sensor Technology and Image Quality: Can 1/2.3” Deliver?

The heart of any camera’s image quality is its sensor, so I dedicated significant bench and field testing time to measure their real photographic impacts.

Both cameras utilize CCD sensors of the same tiny 1/2.3” size, around 6.1 x 4.5 mm, but with slightly diverging resolutions:

• Panasonic S2 offers 14 megapixels (4320 x 3240 max)
• Pentax H90 offers 12 megapixels (4000 x 3000 max)

On paper, the S2’s higher pixel count suggests finer detail capture. However, higher megapixel density on such a small sensor can compromise noise performance and dynamic range if not carefully managed.

Color Depth & Noise Performance
In real-world tests, both cameras produce respectable color reproduction considering their sensor limitations. The S2’s colors appear slightly more vibrant but sometimes oversaturated, leaning toward punchy contrast. The H90, thanks to Pentax’s Prime processor, delivers more neutral, faithful skin tones and less color shift under fluorescent lighting.

When pushing ISO sensitivity beyond 800 (native max 6400 on both), noise becomes pronounced on both models. However, I noticed the H90’s noise appears more luminance-based and less colorful grainy - probably due to its sensor-shift stabilization allowing lower ISOs and steadier shots.

Dynamic Range and Low-Light
Sadly, both struggle with dynamic range - the kind of tonal range between shadows and highlights is very limited, so shooting high-contrast outdoor scenes requires care or post-processing fixes. Neither supports RAW capture, which restricts post-shoot adjustments - a major downside for enthusiasts.

Macro and Close Focus
The Panasonic edges ahead with a 5cm macro minimum focusing distance versus the H90’s 10cm - meaning tighter close-ups and enhanced detail capture in macro scenarios.

Autofocus Systems and Shooting Speeds: For Action or Stillness?

Autofocus can make or break moments, particularly in dynamic scenes like wildlife or sports. Neither camera ventures into advanced AF territory, but the differences are worth noting.

Panasonic S2 AF Highlights

• 23 focus points (contrast detection)
• Face detection AF included
• Single AF only; no continuous, no tracking

Pentax H90 AF Highlights

• 9 focus points (contrast detection)
• AF tracking available (albeit rudimentary)
• Manual focus option (Pentax wins here)
• Face detection absent

In controlled tests tracking moving subjects, neither excelled for fast-moving action. The Panasonic’s face detection helps portraiture but is fairly basic. The Pentax’s AF tracking, albeit limited, showed some promise in continuous focus over slower-moving subjects.

Regarding burst shooting, the S2 clocks a modest 2 fps, while the H90 maxes out at 1 fps - neither suitable for serious sports or wildlife bursts but adequate for casual photography.

Build Quality and Weather Sealing: Ready for Rough Use?

Neither model claims environmental sealing, dustproofing, or waterproofing - a limitation for outdoor enthusiasts. The S2’s minimalist plastic construction feels less rugged, while the H90’s slightly bulkier shell hints at better durability but remains no substitute for a weather-sealed mirrorless or DSLR.

If your photography regularly takes you outdoors in inclement weather, neither choice scores well here.

LCD Screens & Playback Experience: Keeping Your Eye on the Shot

Both cameras sport identical 2.7-inch TFT LCDs with 230k-dot resolution and fixed positioning. This modest screen quality is typical for their era but frustrating under bright daylight due to glare and low brightness.

The interface usability is straightforward on both, with logical menus and no touchscreen capability. Pentax’s interface feels slightly more responsive, likely aided by its Prime processor.

Neither has an EVF, limiting framing options in direct sunlight. For serious framing, shooting at dawn/dusk or in shaded conditions works best.

Lens Specifications & Optical Performance: Versatility vs Aperture

The Panasonic’s fixed zoom lens covers 28–112 mm (4× zoom) with an aperture of f/3.1–6.5 - relatively slow at the telephoto end, which combined with the small sensor, limits background blur and depth of field control.

Pentax’s 28–140 mm (5× zoom) lens extends reach noticeably farther, stopping down slightly slower at f/3.5–5.9, a minor but meaningful bonus for travel and landscape telephoto framing.

Neither offers interchangeable lenses, so optical performance is locked-in. The Pentax lens exhibits mild barrel distortion at wide angles but tightens up past 50 mm. Panasonic optics are sharp centrally but soften noticeably at edges and tele-end. Both excel at typical everyday shooting distances.

Video Capabilities: Not Designed for Cinematography

For those hoping to shoot video, both cameras max out at 720p HD (1280×720) at 30 fps, encoded in Motion JPEG - a format that’s space-hungry compared to modern codecs.

Neither has microphone or headphone ports for audio monitoring, nor do they support 4K or advanced video features such as stabilization in video mode (beyond image stabilization for still frames).

If video is a high priority, these models fall short compared to contemporary compacts or mirrorless hybrids.

Battery Life, Storage & Connectivity: Staying Powered and Connected

The Panasonic S2 offers approximately 280 shots per charge - a modest endurance that’s typical but calls for spares during extended outings. The Pentax H90’s battery life is less clearly specified but tends to be similar; its use of D-LI68 batteries implies a slightly bulkier power source.

Both employ a single SD/SDHC card slot - with the Panasonic also supporting SDXC formats, offering future-proofing for larger cards.

Connectivity is limited. The Pentax H90’s unique feature is Eye-Fi card compatibility, providing rudimentary wireless transfer via an SD card. The Panasonic lacks any wireless or Bluetooth options entirely. Neither offers GPS or HDMI out.
