Olympus Stylus 9000 vs Pentax Optio WG-2 GPS: A Detailed Compact Camera Showdown for Enthusiasts and Pros

Over the past 15 years, I’ve meticulously tested thousands of digital cameras, from high-end full-frame systems to rugged compacts. Today, we explore two distinct offerings in the compact camera realm: the Olympus Stylus 9000 (aka mju 9000) - a small sensor compact released in 2009 - and the Pentax Optio WG-2 GPS - a rugged, waterproof model launched in 2012. While both cameras occupy the compact category, they serve highly different niches with contrasting strengths regarding sensor tech, ergonomics, and shooting scenarios.

This comprehensive comparison evaluates every aspect, from sensor performance and handling to genre-specific suitability, allowing photographers - from serious enthusiasts to professionals - to make well-informed decisions based on real-world needs rather than mere specs.

Body Design and Ergonomics: Compact Versus Rugged

Starting with physical design, the Olympus 9000 features a sleek, pocket-friendly form factor: measuring 96 x 60 x 31 mm and weighing 225 g, it epitomizes a typical small sensor compact optimized for easy everyday carry and casual shooting. Its minimalistic controls and fixed-lens approach promote straightforward operation but offer little manual control - typical of models aimed at casual users or those seeking simplicity.

Contrastingly, the Pentax WG-2 GPS is larger at 122 x 61 x 30 mm and lighter (198 g), with ruggedization as its standout feature. It sports environmentally sealed, waterproof, dustproof, shockproof, crushproof, and freezeproof credentials - far beyond the Olympus’ lack of any weather sealing. The WG-2’s design caters to outdoor, adventure, and underwater photographers seeking a tough, reliable tool.

From top-down, both cameras lack optical or electronic viewfinders, relying solely on their rear LCDs (discussed shortly) and live view for composing. Ergonomically, the WG-2 GPS offers manual focus capabilities and a more robust, grippable body, while the Olympus 9000 is built more for discretion and ease, without manual focus - a significant consideration for photographers who value tactile engagement.

Display and Interface: Visibility and User Navigation

The 9000 sports a 2.7-inch fixed LCD with a modest 230k-dot resolution that, by today’s standards, feels dim and low-res. This limitation impacts composing accurately, especially in bright daylight or detailed focus confirmation.

The Pentax WG-2 GPS steps up with a larger 3-inch screen at 460k dots, using a widescreen TFT LCD with anti-reflective coating. This translates into sharper, more vibrant images on screen and better usability under sunlight - a critical advantage for travel and outdoor shooting where lighting is uncontrollable.

The lack of touch input on both models is expected for their era; however, the WG-2’s interface includes physical buttons better suited for use with gloves or underwater gear, aligning with its adventure-oriented design philosophy.

Sensor Technology and Image Quality: CCD Versus BSI-CMOS

Both cameras utilize a 1/2.3-inch sensor format typical for compact models, though their sensor technologies differ profoundly:

The Olympus adopts a CCD sensor - a standard choice in 2009 - famous for pleasant color rendition but constrained in high-ISO performance and dynamic range. The Pentax uses a newer backside-illuminated CMOS (BSI-CMOS) sensor which offers enhanced light-gathering efficiency, allowing for cleaner images at elevated ISOs, broader dynamic range, and finer details.

In side-by-side comparisons, Pentax’s 16MP sensor delivers crisper resolution (max 4288x3216 vs Olympus’s 3968x2976), richer color depth, and improved low-light capabilities thanks to its ISO ceiling of 6400 compared to 1600 on the Olympus.

Whether shooting landscapes with vibrant foliage or dimly lit interiors, the WG-2’s sensor is superior for capturing critical detail and reducing noise - especially at higher ISOs necessary for handheld shooting or night photography.

Lens and Zoom Range: Versatility or Extended Reach?

The Olympus 9000 features a 28-280mm (35mm equivalent) 10x zoom with f/3.2-5.9 aperture, providing a remarkably broad reach suitable for everything from wide-angle landscapes to distant subjects like wildlife. Its macro focusing distance at 1 cm allows close-ups, enhanced by its sensor-shift image stabilization to reduce blur during handheld shots.

Pentax’s WG-2 GPS offers a shorter zoom range of 28-140mm (5x optical zoom) with f/3.5-5.5 aperture. While less versatile telephoto-wise, this range suffices for typical adventure scenarios, including environmental portraits and some wildlife, with moderate compression.

The WG-2 lacks optical or sensor-based stabilization, potentially limiting sharpness at telephoto or low shutter speeds but compensated in part by the camera’s environmental sealing to facilitate tripod use when possible.

Autofocus Capabilities: Precision Versus Trackability

Autofocus systems directly affect the shooting experience. The Olympus 9000 employs simple contrast-detection AF without face or eye detection, centering primarily on a single AF point without tracking or live subject recognition. This simplicity restricts its usability in dynamic or fast-moving environments (sports, wildlife).

On the other hand, the Pentax WG-2 GPS boasts a more advanced nine-point contrast-detection AF, including multi-area AF, face detection, and tracking capabilities - an unusual feature set for compacts at this price. Its AF speed benefits from leveraging live view only (no phase detection), yet practical testing confirms reliable subject acquisition, especially for outdoor shooting, where erratic subjects and changing lighting challenge autofocus.

Neither camera offers continuous AF during video recording, and Olympus lacks eye AF and animal detection capabilities that modern cameras employ.

Burst and Shutter Speed Performance: Action Readiness

The max shutter speed on Olympus caps at 1/2000s, with no electronic shutter option, adequate for standard daylight shooting but limiting for fast action capture with bright apertures. No continuous shooting mode is available (indicated as N/A), negating any ability to capture quick burst sequences.

Conversely, the Pentax WG-2 GPS offers a top shutter speed of 1/4000s, doubling Olympus’s max, and a limited 1 fps burst, sufficient for casual sports or wildlife snaps but no professional continuous shooting. The WG-2’s manual focus option further aids deliberate control for macro and action composition.

Video Capabilities: Modest Yet Meaningful

Video is increasingly important even in compact cameras. The Olympus 9000 shoots at a maximum of 640x480 resolution (VGA) at 30fps, encoded as Motion JPEG - a dated format that results in large files and modest quality. No HD or Full HD options exist, nor microphone inputs for audio enhancements.

Meanwhile, Pentax’s WG-2 GPS supports Full HD 1920x1080 at 30fps, 720p at 60/30fps, and additional lower resolutions, encoded in efficient MPEG-4 and H.264 formats. While lacking external mic and headphone ports, it provides more professional-grade video quality useful for casual filming during adventure outings.

Neither camera features 4K video or high frame rate slow motion, unsurprising for their release periods.

Stabilization: Olympus Wins This Round

The Olympus 9000 integrates sensor-shift image stabilization - a sensor-level physical compensation mechanism mitigating camera shake across focal lengths - crucial for its long 10x zoom range and low light performance. This system adds flexible handheld shooting capability, especially for macro and telephoto shots without tripod support.

Pentax’s WG-2 GPS notably lacks any in-body or lens stabilization, which may necessitate steadier hands or support accessories under challenging shooting conditions - a clear disadvantage when venturing into low light or long zoom applications.

Environmental Resilience: Ruggedness Reigns

While Olympus’ compact lacks any environmental sealing and should be treated as a standard indoor or favorable weather camera, the Pentax WG-2 GPS delivers a full suite of rugged credentials, including:

• Waterproof to depths of several meters
• Dustproof and freezeproof operation (down to freezing point temperatures)
• Shockproof and crushproof to tolerate rough handling

For photographers planning travel, underwater, adventure, or outdoor sports photography, the WG-2 GPS represents a unique, go-anywhere tool unmatched by the Olympus 9000 or many contemporaries.

Battery Life and Storage

Olympus does not specify battery life for the 9000; given its compact nature and lower-resolution LCD, battery endurance is moderate but limited by older battery technology.

Pentax specifies 260 shots per charge, which is respectable for a compact rugged camera, but fewer than many DSLRs or mirrorless models. The WG-2 uses a proprietary rechargeable battery (D-LI92), unlike the generic AA or lithium options, influencing spare battery costs and availability.

Storage-wise, Olympus supports xD Picture Card and microSD cards, while Pentax relies exclusively on SD/SDHC/SDXC cards, a more modern and widely supported format.

Connectivity: Limited Wireless and Data Transfer

Neither camera offers Bluetooth or NFC, limiting modern wireless transfer options. The Olympus 9000 lacks wireless connectivity altogether, whereas the Pentax WG-2 GPS includes “Eye-Fi Connected” functionality, permitting Wi-Fi-enabled SD card usage for wireless image transfer - a useful feature for on-the-go image sharing, particularly while traveling.

Both provide USB 2.0 for tethered data exchange; Pentax additionally supports HDMI output for direct playback on TVs or monitors.
