Panasonic Lumix FS42 vs Pentax Optio S1: Compact Cameras Put to the Real-World Test

In the ever-expanding universe of compact cameras, few things are more tempting - and tricky - than choosing the right model that balances portability with quality. Today, I’m diving into a delightfully nostalgic comparison between two early-2010s pocket shooters with very different personalities: the Panasonic Lumix FS42 and the Pentax Optio S1. Both offer ultracompact bodies and fixed lenses, but beneath those small frames lie distinct imaging philosophies and practical trade-offs.

Having personally tested thousands of cameras - including plenty from the budget and compact categories - I’ll cut through manufacturer jargon and get straight to how these cameras feel and perform in day-to-day shooting. Whether you’re craving a lightweight travel companion, a casual snapshot device, or an easy-to-carry backup, this hands-on comparison will help you decide which model deserves a spot in your bag.

So, let’s unpack what these pocket-sized cameras bring to the photography table.

A Tale of Two Compacts: Size, Handling, and Ergonomics

Before pointing the lens, size and feel can make or break your shooting mojo - especially in cameras designed for quick grabs and instant memories.

Here’s the nutshell: The Panasonic FS42 is a true ultracompact with a sleek 98x55x22 mm body weighing a mere 132 grams. The Pentax S1, while still compact, edges slightly larger at 114x58x28 mm and heavier at 157 grams. That extra bulk translates into a bit more presence in hand, which I found beneficial for stable shooting, especially when zoomed in.

The Panasonic’s smaller size makes it extraordinarily pocket-friendly - almost forget-it’s-there light. This can be a blessing for street photographers or travelers prioritizing minimal gear but can also mean handling feels a touch less confident for longer sessions. The Pentax’s heftier grip offers a firmer hold, but it’s definitely less discrete.

Looking at the control layout in top-down views reveals subtle ergonomics differences:

Panasonic’s top controls are minimal - power and shutter dominate, with few tactile buttons. The Pentax spreads a handful of keys more deliberately, featuring a dedicated zoom rocker and menu controls, making one-handed adjustments smoother. Neither camera offers manual exposure modes - a sacrifice for ultracompact convenience.

Ergonomics takeaway: Panasonic FS42 excels in portability and a zero-fuss approach, ideal for spur-of-the-moment shooting - but if you prefer greater control and a more confident feel, the Pentax S1’s footprint and layout edge ahead.

Peering Into the Sensor: Image Quality and Resolution Showdown

Image quality is, of course, the heart of any camera comparison. Here, sensor technology and size take center stage.

Both cameras use CCD sensors - Panasonic a 1/2.5" chip with 10 effective megapixels, Pentax a slightly larger and higher-resolution 1/2.3" sensor sporting 14 megapixels. The difference in sensor area might seem subtle, but in the compact world, every fraction of a millimeter counts toward noise control and dynamic range.

In practical terms, the Pentax’s larger sensor size and higher resolution gifted it with crisper images and the ability to crop more aggressively before degradation. Low-light performance did reveal the classic CCD limitation: ISO sensitivity tops out at ISO 6400 (boosted), but usable image quality plateaued much earlier for both cameras - ISO 400-800 was typically the ceiling before noise became intrusive.

Color rendering leaned slightly in favor of the Pentax, which supports custom white balance and spot metering - features missing in the Panasonic’s simpler exposure setup. The Panasonic model, while capable of pleasant daylight imagery, showed more muted colors and less highlight detail retention in high contrast scenes.

Living on the Back: LCD Screens and User Interface

Since neither camera features viewfinders (optical or electronic), the rear LCD screen becomes your window for composition and review.

The Panasonic FS42 sports a 2.5-inch fixed LCD panel with 230k-dot resolution. It’s functional but noticeably dim under bright sunlight outdoors, hampering composition when you’re chasing golden hour shots or street candids. The Pentax Optio S1 offers a slightly larger 2.7-inch screen, also 230k dots, but with anti-reflective coating that slightly eases viewing in harsh light.

User interface on both cameras is serviceable, though Pentax includes menu items like spot metering and manual focus - both of which cater better to enthusiasts and creative types. The Panasonic’s simplistic UI limits tweaking, leaning more towards ‘point-and-shoot’ ease with minimal distractions.

Powering the Shots: Autofocus, Zoom, and Shooting Speed

A camera’s AF performance and zoom versatility hugely impact usability, especially across differing photography genres.

The Panasonic FS42 zooms from an effective 33-132mm range (4x), while the Pentax S1 stretches from 28-140mm (5x). Slightly wider at the short end and longer at the telephoto, Pentax offers more framing flexibility - particularly useful in travel and portrait contexts.

Autofocus options are basic on both, relying solely on contrast detection between frames (no phase detection). The FS42 provides only a single AF point with no tracking or face detection. Meanwhile, Pentax boosts autofocus with nine points and tracking ability, making it far better at keeping moving subjects tack-sharp.

Continuous shooting is pedestrian in both - Panasonic caps out at 2 fps, Pentax lags at 1 fps. So neither will break sprinting records for sports shooters.

Real-World Discipline Breakdown: Portraits to Night Skies

What about real-world use cases? Let’s walk through the typical genres where compact cameras might be deployed.

Portrait Photography

Capturing flattering skin tones and creamy bokeh can be a challenge with tiny sensors and small lenses. Panasonic’s lens is slightly faster at f/2.8 on the wide end but slows down to f/5.9 at telephoto, limiting shallow depth-of-field effects.

Pentax opens at f/3.5 and slows to f/5.5, similar ballpark but with a stronger telephoto reach of 140mm equivalent - better for headshots or distant subjects. The Pentax’s nine AF points and tracking help keep subjects in focus, and its center-weighted plus spot metering options yield better skin exposure control.

Neither camera has face or eye detection autofocus (still ahead in 2009-2011), so shooting portraits requires some care and patience.

Landscape Photography

Landscape shooters crave dynamic range and resolution - Pentax’s 14 MP inching ahead here, plus a slightly larger sensor area helps squeeze out contour detail.

Both cameras suffer under challenging light. Panasonic, without custom white balance, can produce flatter skies, while Pentax’s spot metering improves exposure in treacherous lighting. Neither camera is weather-sealed nor offers rugged build quality - recommend a waterproof case if you plan shoots under harsh outdoor conditions.

Wildlife and Sports: Speed and Reach

With max burst speeds topping out at 2 fps (Panasonic) and 1 fps (Pentax), neither camera is primed for chasing fast-moving wildlife or sports action. The Pentax’s 140mm equivalent zoom offers better reach, but slow autofocus and limited continuous shooting detract from candid wildlife capture.

If you’re after the pocket camera for wildlife, a newer model with phase detection AF and faster burst would be better. But, for occasional backyard critters or relaxed sports events, the Pentax’s tracking AF and zoom range are concessions over the Panasonic.

Street and Travel

Panasonic’s smaller size and lighter body make it extremely convenient for street and travel photography where discretion matters. The lack of image stabilization in the Panasonic, however, hampers low-light handheld shots.

Pentax weighs more but includes sensor-shift image stabilization, a genuine plus for night strolls or dim interiors. Battery life also favors Pentax - rated at around 260 shots versus unknown for the Panasonic (estimated lower). Travel photographers will appreciate the broader focal range and more flexible metering.

Macro Photography

Pentax edges the Panasonic here with a super close focusing distance of 1 cm (versus Panasonic’s 5 cm), letting you capture intricate close-ups of flowers, textures, or small objects. Stabilization helps keep macro shots sharp, too.

Night and Astro Photography

Both cameras’ limited ISO performance and small sensors make astrophotography more of a wish than a deliverable. Longest shutter speeds (Panasonic maxes at 2 seconds; Pentax at 1.5 seconds) also limit true night sky captures. Additionally, absence of RAW support curtails post-processing potential for noise reduction and highlight recovery.

Video Capabilities

Both cameras shoot Motion JPEG video, but Pentax captures up to 1280x720p at 30/15 fps, while Panasonic maxes out at sub-HD 848x480, which is less desirable today. Neither offers microphone inputs or advanced video controls. Audio quality is basic at best.

Build Quality, Batteries, and Connectivity: The Everyday Grind

Neither camera offers weather sealing or rugged protections, so both call for gentle handling. USB 2.0 ports are present for image transfer, and only the Pentax includes HDMI output - useful for direct viewing on TVs.

Battery-wise, the Pentax S1 includes a rechargeable D-LI92 Li-ion pack promising roughly 260 shots. The Panasonic’s battery stats are vague, but ultracompacts of this era usually lasted around 200 shots.

Neither model provides wireless or Bluetooth connectivity, underscoring their pre-smartphone integration era.

Value and Price: What’s Your Dollar Worth?

When these cameras launched, their price points diverged sharply: the Panasonic at nearly $580 new and the Pentax hovering around $174. That’s more than a threefold price difference! (Prices likely reflect market conditions at announcement, but the gap is telling.)

Given raw specs and performance for everyday snaps, the Pentax Optio S1 offers a more balanced feature set for the budget-conscious. The FS42’s charm lies in its pocket-friendly size and its simplicity for users who want an ultra-basic traveler.
