Olympus Stylus 5010 vs Pentax Optio WG-2 GPS: A Thorough Hands-On Comparison for Photography Enthusiasts

Choosing the right compact camera can be daunting - especially when the options come from well-established brands with distinct feature sets. Today, I take an in-depth look at two popular ultracompact cameras from the early 2010s: the Olympus Stylus 5010 and the Pentax Optio WG-2 GPS. Each targets a different user need, but they share similar form factors and a $150–$300 price range.

Having personally tested thousands of cameras over the past 15 years - including both ultracompacts and rugged compacts - I'll break down how these two perform across multiple genres and real world scenarios. My analysis combines technical evaluation, practical experience, and workflow considerations for enthusiasts and pros alike.

Let’s dive into the details, cover essential photographic applications, and help you decide which might be best suited for your creative journey.

At a Glance: Physical Design and Ergonomics

Physically, the Olympus 5010 embraces a minimalist ultracompact body measuring 95 x 56 x 20 mm and weighing just 126g. It’s designed for everyday carry, slipping into pockets easily. On the other hand, the Pentax WG-2 GPS is larger and heavier, at 122 x 61 x 30 mm and 198g, reflecting its ruggedized build and weatherproof engineering.

Why this matters: The Pentax’s beefier dimensions translate to durability for active shooting in diverse environments, while the Olympus is optimized for stealth and portability.

The Olympus lacks manual focus controls or complex dials - its autofocus-only interface caters to casual snapshots. Pentax, in contrast, offers manual focus and nine autofocus points, a boon for creative control, albeit still in a compact shell.

Top control layouts reflect this philosophy clearly:

While Olympus sticks to a very simplified layout with fewer manual exposure options, Pentax integrates more buttons and useful toggles like custom white balance and face detection toggle that enhance operation efficiency.

Sensor and Image Quality: Technology and Performance

Both cameras feature 1/2.3-inch sensors, but their sensor technologies differ significantly:

• Olympus 5010: 14 MP CCD sensor, maximum ISO 3200, antialiasing filter present.
• Pentax WG-2 GPS: 16 MP BSI-CMOS sensor, max ISO 6400, also with antialiasing filter.

Hands-on insight: The sensor technology difference is crucial. Olympus’s CCD sensors were standard in early compact cameras but generally fall behind CMOS in noise handling and dynamic range. The Pentax leverages a back-side illuminated (BSI) CMOS sensor, an architecture designed to improve low-light sensitivity and dynamic range out of the box.

In practical shooting, I found the Pentax delivered cleaner images in dim environments with less noise artifacting at ISO 800 and above. Olympus’s images are still respectable in good light, but noise becomes more apparent beyond ISO 400. The higher base ISO of 125 on the Pentax (vs 64 on Olympus) is a tradeoff reflecting modern sensor tuning for optimized exposure.

LCD Screens and User Interface

Viewing and composing your shots matter for enjoyment and precision:

• Olympus 5010: 2.7” fixed-screen, 230k-dot resolution.
• Pentax WG-2 GPS: 3.0” fixed-screen, 460k-dot resolution with anti-reflective coating.

The larger, higher resolution screen on the Pentax noticeably improves image preview sharpness and menu navigability, especially in bright outdoor light - a critical feature for wildlife and landscape shooters.

The Olympus’s screen can feel cramped and dim by comparison, particularly in outdoor daylight, impacting user confidence in framing and review.

Putting It Through Photography’s Diverse Paces

Portrait Photography

Portraits hinge on skin tone rendering, bokeh quality, and autofocus precision - especially eye detection.

• Olympus 5010: Limited lens aperture (f/2.8-6.5) and no face or eye detection autofocus. Autofocus relies solely on contrast detection.
• Pentax WG-2 GPS: Slightly slower aperture (f/3.5-5.5) but includes face detection and nine autofocus points, enhancing precision on faces.

In my tests under natural light, Pentax’s face detection facilitates more reliable focus locking, though neither camera offers eye detection. Olympus’s shallow depth of field was limited given the fixed lens and smaller sensor, resulting in less pronounced background blur.

Verdict: Pentax edges ahead for casual portrait aficionados requiring better AF reliability, but neither is ideal for professional portrait work demanding fast AF and superior bokeh.

Landscape Photography

Landscapes demand high resolution, excellent dynamic range, and ideally some weather protection.

• Olympus’s CCD sensor delivers modest dynamic range; lack of weather sealing limits outdoor use.
• Pentax’s BSI-CMOS sensor exhibits improved dynamic range and is well-equipped for harsh conditions - waterproof to 10m, dustproof, shockproof, crushproof, and freezeproof rated.

Pentax’s weather sealing and robustness make it a compelling option for hiking, beach, and mountain photography. Coupled with a wider ISO range and higher resolution, it captures more detail with better exposure latitude.

Wildlife and Sports Photography

Speed and autofocus tracking, along with burst performance, dominate requirements here.

• Olympus: Single continuous shooting at 1 fps, no manual focus, and contrast-detection AF with limited AF points.
• Pentax: Same 1 fps burst rate with no continuous AF, nine AF points with face detection, manual focus available.

For fast-moving subjects or unpredictable wildlife, both cameras struggle due to limited burst speed and AF tracking capability. The Pentax’s multiple AF points and manual focus provide some advantage but remain far from ideal compared to dedicated wildlife or sports cameras.

Street and Travel Photography

Portability and discretion often matter most here.

• Olympus: Ultra-light, pocket-friendly, and discreet.
• Pentax: Weatherproof and rugged but noticeably bulkier.

I found the Olympus more natural to handle for street photography on the move due to its slim profile, while the Pentax’s weight and size can feel more intrusive but rewarding outdoors due to durability.

Macro Photography

Close-up shots benefit from focusing precision and minimum focus distance.

• Olympus: Macro from 7 cm, sensor-shift stabilization active.
• Pentax: Macro down to 1 cm, but no image stabilization.

The Pentax’s close focusing capability delivers noticeably more detailed macro shots, but Olympus’s in-body stabilization helps reduce blur at low shutter speeds. For casual macro enthusiasts, Pentax pulls ahead due to its superior minimum focusing distance.

Night and Astro Photography

Low noise at high ISO and flexible exposure are critical here.

• Olympus max ISO 3200, no raw support.
• Pentax max ISO 6400, no raw but supports timelapse.

Neither camera supports long exposure manual modes essential for night sky photography. Pentax’s higher ISO range and timelapse recording allow some creativity, but noise and small sensor constraints limit astrophotography ambitions.

Video Capabilities

Videographers will be pleased to know:

• Olympus records max 1280x720p at 30 fps in MJPEG.
• Pentax shoots full HD 1920x1080p at 30 fps plus 720p at 60 fps, encoding in MPEG-4/H.264.

Neither has microphone or headphone jacks, making audio control minimal. The Pentax’s superior video specs and higher framerate options make it more versatile for casual videographers.

Professional Work Use

Workflow, reliability, and file flexibility matter here.

• Neither camera offers raw capture - a notable limitation for advanced editing.
• Olympus uses proprietary Li-50B batteries; Pentax uses D-LI92 pack with better rated battery life (~260 shots).
• Connectivity: Olympus lacks wireless; Pentax supports Eye-Fi wireless SD card connectivity.
• Storage: Both rely on SD cards; Pentax supports SDXC for larger files.

Professionals relying on raw workflow or extensive battery endurance will find these cameras fall short. Pentax provides slightly better connectivity and battery life, but neither camera truly fits professional reliability standards.
