Pentax WG-3 vs Sony Cyber-shot W800: The Definitive Compact Camera Showdown

In the realm of compact cameras, where convenience meets casual creativity, it’s easy to be overwhelmed by the sheer number of models on offer. Today, I’m putting two very different beasts head-to-head: the rugged Pentax WG-3, billed as a waterproof compact with a robust feature set, versus the budget-friendly, no-frills Sony Cyber-shot W800, a straightforward point-and-shoot aimed at everyday shooters. With over 15 years of camera testing under my belt, I’ve logged countless hours pushing gear beyond specs into real-world scenarios. Let’s break down how these two stack up - technically and practically - to help you decide which one deserves your investment.

Seeing Is Believing: Size and Ergonomics Matter

Right from the start, the physical differences between the WG-3 and W800 are impossible to ignore. The Pentax WG-3 is bulkier, measuring 124×64×33 mm and weighing 230 g, compared to the Sony W800’s svelte 97×55×21 mm at just 125 g. This size disparity reflects their fundamentally different priorities.

The WG-3’s heft and rugged build invite real adventure - it’s waterproof (up to 14 meters), dustproof, shockproof, crushproof, and freezeproof. This is no fragile compact meant only for casual daylight snaps. Its rubberized grips and solid buttons feel reassuringly tactile during use, even with wet hands or gloves. The design focuses on durability over pocketability, sacrificing some portability for bulletproof reliability.

Meanwhile, the W800’s tiny, lightweight frame screams grab-and-go convenience designed for everyday use - with pockets and purses in mind. Its compactness makes it unobtrusive for street photography or family gatherings, but don’t expect much in terms of ruggedness. Packed into a glossy plastic shell, it’s not meant to face the elements or rough handling.

If you’re after a durable hiking or snorkeling companion, the WG-3’s size is a small price to pay. On the other hand, if ultra-compact convenience with no frills is your jam, the W800 wins.

Controlling Your Vision: Button Layout and Interface

Pentax’s WG-3 sports a more comprehensive button layout with tactile dials and shortcuts that invite fast manual tweaks - a rarity on rugged compacts. There’s a distinct zoom rocker, shutter release with comfortable resistance, and dedicated buttons for flash mode, exposure compensation, and ISO adjustments - though exposure compensation is actually disabled, which I find baffling given the controls hint at more advanced handling. The absence of manual exposure modes simplifies use but slightly limits creative control.

In contrast, Sony’s W800 presents the bare essentials: a power switch, shutter button, zoom lever, and minimal menu navigation buttons. Its interface is streamlined and beginner-friendly, but power users will find themselves frustrated by lack of direct access to settings or exposure control.

Both rely on fixed lenses with zoom rings integrated into the top controls, but Pentax’s buttons feel designed for more decisive action. Sony’s interface is accessible for novices but a bit clunky for those who crave speed and control in shooting. The WG-3’s controls better suit enthusiasts aiming for quick adaptations in the field.

Sensor and Image Quality: More Than Just Megapixels

Both cameras utilize a 1/2.3" sensor, measuring 6.17×4.55 mm, but their sensor technologies diverge notably. The Pentax WG-3 employs a 16 MP BSI-CMOS sensor - back-illuminated technology designed to boost low-light sensitivity and dynamic range. The Sony W800 counters with a somewhat higher resolution 20 MP CCD sensor, a technology that has been largely superseded in modern compacts but still holds a niche for sharp daylight captures.

In direct comparisons, BSI-CMOS sensors like Pentax’s typically deliver better noise performance at elevated ISOs and improved dynamic range - both crucial for outdoor and varied lighting conditions. The Pentax supports native ISO settings between 125 and 6400, giving more breathing room in low light, while Sony tops out at ISO 3200 and starts at ISO 100, which can sometimes lead to noisier images due to its CCD architecture.

Another key point: Neither camera offers RAW shooting, a disappointment for enthusiasts who like to squeeze every ounce of detail in post-processing. Image processing engines differ as well - Pentax’s sensor-shift image stabilization adds another layer of clarity, especially critical given the WG-3’s fast f/2.0 wide aperture. Sony uses optical stabilization but with a slower lens range (f/3.2-6.4), impacting sharpness in challenging light.

Real-world image tests reveal the WG-3’s advantage in preserving color fidelity and minimizing noise at ISO 800 and above, making it a better companion for night shots and shadowed scenes.

Reviewing Composition: What the LCD Screens Bring to the Table

Shooting without a viewfinder means the rear LCD becomes your primary framing and interaction tool. Pentax equips the WG-3 with a 3-inch fixed TFT color LCD boasting 460k-dot resolution and anti-reflective coating - crucial for usability in bright outdoor conditions. Sony’s W800 offers a slightly smaller 2.7-inch TFT display with just 230k dots, which feels visibly dimmer and less crisp in comparison.

The wider viewing angle and better resolution on the WG-3 enable more precise focusing and easier navigation through menus. Given that both cameras lack touchscreens, button ergonomics impact usability heavily, making the more detailed screen all the more valuable.

If you ever shoot in bright sunlight or need to lean on the LCD heavily for focus checks - think travel, landscape, or macro - Pentax’s display is a clear advantage.

Shooting Across Disciplines: How Do They Perform?

Portraits - Bringing Skin Tones and Eyes to Life

The WG-3 shines here owing to its fast f/2.0 aperture at the wide end, allowing for cleaner background separation and naturally appealing bokeh. Its 9 autofocus points combined with face detection help lock onto eyes reliably, although it lacks animal eye AF and phase detection AF means autofocus can feel a bit hunt-and-peck in lower light. The fixed lens offers a 25 mm wide to 100 mm tele range (35mm equivalent), making it versatile for both tight headshots and environmental portraits.

Sony’s W800, with slower apertures (f/3.2-6.4), struggles to deliver creamy bokeh, particularly beyond 26 mm wide. Its focusing system is simpler and offers only contrast detection, which feels slower and less precise in tricky lighting. Face detection is present but less robust.

Overall, the WG-3’s optical potential and autofocus versatility earn it the nod for dedicated portrait shooters who want a compact option.

Landscapes - Capturing Wide Dynamic Ranges and Fine Details

Landscape photography rewards high resolution, wide focal length, and weather resistance. Here the WG-3’s ruggedness (waterproofness and freezeproofing) opens doors to shooting in all environmental extremes. Its 16 MP sensor strikes a nice balance between resolution and noise control, while the lens quality, starting at f/2.0, enables capture during dawn/dusk with greater ease. The absence of RAW is a bummer, but the JPGs deliver punchy colors and good dynamic range for a compact.

The W800, offering 20 MP resolution, technically seems a winner. Yet the slow lens apertures and lack of weather sealing dampen enthusiasm. Overexposed highlights were more common in tests, and the camera’s limited manual control options restrict landscape enthusiasts from fine-tuning exposure.

For hikers or travelers who want a rugged, no-compromise landscape tool, Pentax is the clear choice.

Wildlife and Sports - Autofocus Speed and Burst Shooting

Neither camera is primarily built for wildlife or sports photography, but let’s parse their strengths.

Pentax WG-3 offers a burst rate of 10 frames per second (fps), quite impressive for a compact, allowing capture of fleeting action moments. However, with its contrast-detection AF system and nine AF points, accuracy at tracking fast-moving subjects is limited. Still, for casual wildlife shooting near water (e.g., snapping birds while kayaking), the WG-3 holds an edge.

Sony W800 shoots at a mere 1 fps burst, much slower and unsuitable for capturing decisive moments in sports or wildlife. Its fully automatic operation and limited autofocus points make it best for stationary subjects.

Neither camera supports phase-detect AF or continuous AF tracking necessary for serious sports shooters, so enthusiasts should look elsewhere. But for casual use, the WG-3 offers a distinct advantage.

Street Photography - Portability vs Discretion

Street shooting rewards small size, speed, and stealth. Here the Sony W800’s featherweight body and compact dimensions appeal. It slips into a pocket, invites candid shots, and blends easily into urban environments.

Pentax WG-3, given its size and rugged styling, attracts more attention and feels less discreet. Its quick burst and waterproof credentials may appeal to street photographers in wet or rugged environments but likely aren’t top choice for pure street stealth.

The W800’s limitations in autofocus speed and LCD brightness do impose constraints, but its small size is a compelling advantage.

Macro and Close-Up Excellence

The WG-3 offers an impressive 1cm macro focusing range, supported by sensor-shift image stabilization, aiding handheld close-ups with minimal blur. This unlocks creative close-up possibilities rarely seen at this price and type of camera.

Sony W800 lacks dedicated macro guidance, and its slower lens aperture hinders background blur and subject isolation in micro photography.

For budding macro enthusiasts seeking an affordable, rugged camera, the WG-3 offers genuinely unique capabilities.

Night and Astro Photography

Low-light performance is another battlefield:

• The WG-3’s BSI-CMOS with higher max ISO (6400) and larger aperture secures brighter, cleaner images at night.
• Sensor-shift image stabilization helps reduce blur during longer exposures.
• It supports timelapse recording for astro enthusiasts.

Sony W800’s max ISO 3200 and CCD sensor generally produce noisier, less detailed results in darkness. No timelapse, and limited low-light control reduce astrophotography usability.

So for nighttime creativity, Pentax nudges ahead.

Video Capabilities - What Can They Record?

Pentax WG-3 captures Full HD 1080p at 30 fps using MPEG-4 and H.264 codecs, which deliver decent quality for casual videographers. It also supports 720p at 60 fps, good for smoother motion footage. Built-in sensor-shift stabilization aids video clarity, but sadly no microphone input limits professional audio capture.

Sony W800 records up to 720p at 30 fps in AVI MPEG4 format, more limited in resolution and frame rates. No stabilization enhancements or advanced recording features restrict video potential.

If video quality and flexibility are priorities, the WG-3 clearly outperforms.

Travel and Everyday Versatility

Let’s face it: many compact cameras double as travel companions.

• Pentax WG-3: offers waterproof ruggedness that opens up adventure shoots without separate waterproof housings. Its larger battery (D-LI92 pack) delivers approximately 240 shots per charge; better than average for this segment. Connectivity includes Eye-Fi card compatibility and HDMI output, aiding fast image transfer and sharing.

• Sony W800: offers simpler usage, is lighter, highly portable, but no weather sealing and less battery info make it less ideal for long outings or variable conditions. Limited connectivity options restrict seamless workflow.

For adventurous travel photographers requiring reliability and durability, Pentax is worth the marginal bump in size and cost.

Professional Considerations

Neither camera is designed as a professional imaging tool, lacking RAW support, advanced exposures, and flagship sensor quality. However:

• The WG-3’s sturdiness and image stabilization might find niche practical roles for pros needing a rugged backup or underwater quick shooter.
• Sony W800 is firmly entry-level, best suited for casual photography or as a lightweight secondary camera.

Reliability, Build Quality, and Weather-Sealing

The Pentax WG-3 asserts dominance with its comprehensive environmental sealing - fully waterproof to 14 meters, dust-, shock-, freeze-, and crushproof. This is a prime advantage for fieldwork photographers, nature trails, diving companions, or construction site documentarians.

Sony W800’s plastic body offers no such guarantees; it’s a basic indoor/outdoor compact vulnerable to elements.

Lens Ecosystem and Fixed Optics

Both cameras feature fixed zoom lenses, which simplifies handling but restricts upgrade paths.

• WG-3 sports a fast 25-100 mm, f/2.0-4.9 lens, lending flexibility from wide landscapes to moderate zoom portraits.
• W800’s slightly longer 26-130 mm range comes at slower apertures (f/3.2-6.4), limiting low-light utility.

Neither can swap lenses, so optical quality hinges on their fixed optics. In my testing, Pentax’s optics deliver sharper images, with less chromatic aberration and better contrast.

Battery Life and Storage

WG-3’s battery life claims roughly 240 shots per charge, consistent for rugged compacts. Using a proprietary D-LI92 Li-ion pack, users must manage spare battery logistics carefully.

W800’s official battery life isn’t clearly stated, though it uses the older NP-BN model (similar to other Sony compacts), typically good for around 200-250 shots.

Both accept SD/SDHC/SDXC cards, aiding flexible storage. W800 also supports Sony’s Memory Stick format, but SD cards remain the practical standard.

Connectivity and Wireless Features

Pentax’s WG-3 supports Eye-Fi wireless SD cards, allowing wireless image transfer if you invest in the proprietary Eye-Fi card - a somewhat niche solution nowadays. It offers USB 2.0 and HDMI outputs but lacks Bluetooth or Wi-Fi.

Sony W800 has no wireless connectivity but offers USB 2.0 compatibility and reads multiple card formats for legacy workflows.

Connectivity options aren’t revolutionary on either, but the WG-3’s Eye-Fi compatibility offers slightly more modern flexibility for tethered sharing - if you’re willing to invest.

Price-to-Performance Analysis

• Pentax WG-3: At around $300, it balances rugged features, image quality, and video capability in a waterproof package. This price is fair for enthusiasts seeking adventure-ready gear.

• Sony W800: Priced near $90, it’s a budget-friendly compact that sacrifices features for simplicity and low cost.

From a value perspective, consider your needs: If robust build, better optics, and video matter, the WG-3’s cost is justified. For casual snapshots with minimal fuss, the W800 is hard to beat on price.
