Both vying for your crowdfunded expedition snaps, these tough compacts hail from prominent camera makers with a legacy of durability and imaging innovation. Yet, when put head-to-head after thorough, hands-on testing, their differences shine through in ways that make one better suited for certain users and styles of photography.

Having spent over a decade testing thousands of cameras across fields, I’ve developed a keen sense for how technical specs translate into real-world performance. In this article, I unpack the nuanced contrasts between the Olympus 6020 and Pentax WG-2 GPS - from sensor and autofocus mechanics to ergonomics and shooting versatility across multiple photographic disciplines. Whether you’re an avid hiker chasing that perfect landscape light, a wildlife shooter needing a quick burst in tough conditions, or simply after a dependable travel companion, I’ll help you understand which of these rivals really earns its keep.

Let’s dive in with a close look at their physical presence.

First Impressions: Size, Handling, and Control Layout

The Olympus 6020 and Pentax WG-2 GPS, though both compact waterproof cameras, approach ergonomics with slightly different philosophies - one more streamlined, the other more robust. Handling is crucial with rugged compacts, as you often shoot under adverse conditions with gloves or damp hands.

Olympus 6020 (left) vs Pentax WG-2 GPS (right) - side-by-side size comparison.

The Olympus 6020 is noticeably smaller and lighter - tipping the scales at just 122 grams and a compact 95 x 62 x 22 mm footprint. Its slim profile sits nicely in one hand, with slightly rounded edges that feel comfortable in a variety of grips. However, the smaller size means fewer physical controls, which simplifies operation but limits manual direct access to settings. It’s a camera that visually whispers “light travel companion” rather than “beast in the wild.”

The Pentax WG-2 GPS, on the other hand, feels like a rugged brick - weighing 198 grams and sized at 122 x 61 x 30 mm. Its more substantial body has aggressively textured rubber grips, designed expressly for durability and sure-hold in slippery environments. Buttons are larger, spaced out, and more tactilely pronounced, catering to swift adjustments mid-action - even with gloves on. This model is a bit chunkier but rewards users who prize solid control and confidence in tough conditions.

Moving to the top panel, where key controls live, the differences persist.

The Olympus 6020 keeps its control scheme minimalist: a simple on/off switch, zoom lever, and shutter button dominate the space, with a small mode dial providing limited shooting options beyond program automatic exposure. The Pentax WG-2 GPS opts for more buttons - including dedicated macro and video recording functions - which enhances on-the-fly versatility. In my tests, I found the Pentax’s approach quicker for changing modes without digging into menus, an important factor in fast-moving scenarios like wildlife or sports.

Both cameras lack electronic viewfinders, so you’ll rely entirely on their rear LCD screens for composing shots - a limitation when shooting in bright sunlight or fast action situations.

Viewing and User Interface: LCD Performance Matters

Compact cameras depend heavily on their rear LCDs, especially without viewfinders. Here, the Pentax significantly outshines the Olympus.

The Pentax WG-2 GPS boasts a larger 3-inch screen with a crisp 460k-dot resolution and anti-reflective coating. This translates into clear, vibrant previews even under harsh sunlight. Live view autofocus performance also benefits from this improved display fidelity and resolution.

Meanwhile, the Olympus 6020 sports a smaller 2.7-inch fixed screen with a modest 230k-dot resolution. The screen can feel dull and less sharp, with a narrower viewing angle that hinders composition outdoors. During field tests on sunny alpine hikes, I often squinted to verify focus or exposure details on the Olympus compared to the much clearer Pentax display.

Neither model supports touchscreen input or an articulating screen, which limits intuitive control and creative shooting angles. In this segment, the Pentax pulls ahead comfortably thanks to its superior size and clarity.

Sensor and Image Quality: Pixels, Noise, and Fidelity

Let’s get to the heart of image creation - the sensor. Both cameras use a tiny 1/2.3-inch sensor, common in compacts, but Olympus and Pentax differ in sensor type and processing approach.

• Olympus 6020: 13MP CCD sensor, TruePic III image processor
• Pentax WG-2 GPS: 16MP BSI-CMOS sensor, image processor unspecified

Sensor Technology and Impact

The Olympus 6020 uses an older CCD sensor. Traditionally, CCD excels in color rendition but struggles with higher ISO noise and dynamic range. The modest TruePic III processor doesn’t fully mitigate these shortcomings.

The Pentax WG-2 GPS embraces a modern back-illuminated CMOS sensor, which inherently improves low-light sensitivity and dynamic range through better photon capture efficiency. This sensor, combined with updated processing, gives Pentax a visible edge in image quality, especially in challenging lighting.

Resolution and ISO Performance

Pentax’s 16MP sensor offers a minor resolution bump over Olympus’s 13MP, which translates into subtly crisper details and better cropping flexibility. However, the practical advantage is more pronounced in higher ISO capabilities:

• Olympus max ISO 1600, base ISO 64
• Pentax max ISO 6400, base ISO 125

In daylight conditions, differences are minimal. But at ISO 800 and above - frequently needed in shaded forests or dawn/dusk shoots - Pentax’s sensor preserves details markedly better with less noise and more natural grain structure.

Raw Support and File Quality

Neither camera supports raw capture - a significant limitation for photographers wanting maximum post-processing latitude. Both rely on JPEG output, which hurts professionals desiring fine-tuned control but is par for the course among rugged compacts.

Autofocus Systems: Speed, Accuracy, and Versatility

Fast, accurate autofocus is essential when you can’t reposition for multiple shots - wildlife, sports, or spontaneous street moments, for example.

• Olympus 6020 offers contrast-detection AF, single AF with some tracking, no face detection
• Pentax WG-2 GPS provides contrast-detection AF with tracking and face detection, plus manual focus support

The Pentax also boasts 9 autofocus points, whereas Olympus does not specify point count - it relies on multi-area AF without face or eye detection technology.

In practical use, the Pentax WG-2 GPS displayed noticeably faster autofocus acquisition, especially in mid-range distances. In shaded or lower contrast scenes, Olympus struggled to lock focus quickly, occasionally hunting - a common drawback of older CCD contrast systems.

Face detection in Pentax proved useful for casual portrait situations - an edge when shooting people on hikes or travel. Olympus’s lack of this feature means more manual framing and timing from the operator.

Build Quality and Weather Sealing

Both cameras are designed to endure moisture, shocks, and temperature extremes, but Pentax ups the ante with crushproof and dustproof ratings.

• Olympus 6020: Waterproof to 10m, shockproof to 1.5m, freezeproof
• Pentax WG-2 GPS: Waterproof to 14m, shockproof to 1.5m, crushproof (100kgf), freezeproof to -10°C, dustproof

In comparative field tests including beach swims, rocky trails, and cold mornings, the Pentax’s tougher sealing and construction instilled greater confidence in harsher environments. The crushproof rating, though not often tested by normal users, could be a lifesaver in extreme situations.

The Olympus offers adequate weather resistance for moderate water sports, hikes, and casual outdoor photography, but heavy-duty adventurers will likely prefer the Pentax’s more resilient shell.

Lens and Optical Performance

Both cameras feature an identical focal length range: 28-140mm equivalent zoom with ~5x optical zoom. Yet, the Pentax starts slightly faster at f/3.5 max aperture versus Olympus’s f/3.9.

In testing, both lenses delivered decent sharpness centrally but softness and chromatic aberrations became noticeable at full zoom and wide apertures - common compromises in compact fixed lenses.

Olympus includes sensor-based image stabilization, which helped moderately with handheld blur in low light. The Pentax surprisingly lacks stabilization, making it more challenging to shoot sharp images in dim conditions without tripod support or boosted ISO.

For macro, both cameras boast a close focusing distance of about 1 cm, enabling impressive close-ups. Pentax’s extra resolution helps detail extraction here.

Burst Rate and Continuous Shooting

Speed matters for wildlife and sports photography, and here Olympus saw an advantage:

• Olympus 6020: up to 5 fps continuous shooting
• Pentax WG-2 GPS: capped at 1 fps continuous shooting

Practically, Olympus’s faster burst allows for better timing and frame selection when photographing erratic subjects. Pentax’s slower rate limits its effectiveness in action sequences and could frustrate users seeking decisive moments in motion.

Video Capabilities

Video is often an overlooked but important feature for rugged cameras capturing dynamic adventures.

• Olympus 6020 records HD at 1280x720 30fps, plus VGA and QVGA options, encoded in H.264
• Pentax WG-2 GPS delivers Full HD 1920x1080 at 30fps plus HD at 60fps and lower resolutions, using MPEG-4 and H.264

Pentax offers better specs with full HD recording and smoother high frame rate options. This grants greater flexibility for slow-motion or high-quality clips from expeditions.

Neither camera has microphone or headphone jacks, limiting audio control. Both lack optical stabilization during video, which leads to noticeable shake unless using a stabilizing rig.

Battery Life and Storage

• Olympus 6020 uses a proprietary Li-50B battery, with unspecified battery life in official specs but generally rated for about 200 shots in real use.
• Pentax WG-2 GPS employs a D-LI92 battery, rated for around 260 shots per charge.

Both cameras use a single SD/SDHC card slot with internal memory fallback. The Pentax additionally supports SDXC cards for expanded capacity, a benefit for longer trips or extensive shooting. Olympus’s lack of explicit SDXC support is a minor limitation in today’s standards.

Connectivity and Extras

Connectivity is sparse on both cameras, reflecting their outdoor focus and era.

• Olympus 6020: no wireless features, basic USB 2.0 and mini HDMI outputs.
• Pentax WG-2 GPS: offers Eye-Fi wireless card support for remote image transfer and built-in GPS geotagging.

The Pentax’s GPS functionality is useful for travel and adventure photographers who want their shots automatically geo-stamped - a huge time saver in mapping journeys and geospatial cataloging.

Neither includes Bluetooth or NFC, and neither supports smartphone remote control or advanced wireless workflows common in modern cameras.
