Olympus TG-810 vs Pentax Optio WG-2 GPS: The Ultimate Waterproof Compact Showdown

When it comes to rugged, waterproof compacts, enthusiasts often feel caught between enthusiasm and pragmatism. Which camera will survive your adventures without sacrificing image quality or usability? Today, I’m diving deep into a head-to-head comparison of two stalwarts in this niche - the Olympus TG-810 and the Pentax Optio WG-2 GPS. Both are designed to brave splashy escapades, dusty trails, and unexpected drops, but they approach the challenge with different philosophies.

I’ve owned and tested thousands of cameras over the past 15 years, including rugged models like these. My aim here: cut through specs and marketing fluff to deliver practical knowledge, relatable insights, and technical assessments that help you make the right call for your rugged shooting needs.

Let’s unpack how these two cameras stack up - from ergonomics to image quality, and everything in between.

Compact but Tough: Size, Build, and Handling

The first impression often hinges on feel and fit in the hand, especially for cameras meant to join you outdoors.

The Olympus TG-810 is noticeably more compact, measuring 100 x 65 x 26 mm and weighing roughly 215 grams. The Pentax WG-2 GPS is slightly larger and chunkier at 122 x 61 x 30 mm and a tad lighter at 198 grams. The Olympus feels like a sleek little boxer - punching above its weight but with a slimmer build. Pentax’s offering, with its a thicker grip and crisper edges, feels more like a durable survivor designed to withstand some real abuse.

Both cameras feature environmental sealing with waterproofing, freezeproofing, shockproofing, and dustproofing baked in. However, Pentax throws in crushproofing, an edge if you are prone to sitting on your gear or tossing it in overstuffed backpacks.

What about ergonomics and controls? Let's take a peek from above.

The ergonomics tell different stories. Olympus keeps a minimalist approach - fewer buttons, limited manual rings (in fact, no manual focus), but a straightforward wheel for zoom and a reliable shutter release. Pentax counters with extra tactile buttons and manual focus capability, appealing to those who want a bit more creative input without fiddling with menus in wet conditions. Notably, Pentax’s buttons are more deeply recessed but have a satisfying click, reassuring in slippery or gloved hands.

For me, outdoor shooting is all about ease of operation without fiddling. The TG-810 offers simplicity - which is a double-edged sword, as we’ll see. If you want sturdy manual overrides, Pentax feels more intentional.

Viewing Your Shot: Screens and Composition

On the rear, you deal with the screen - the primary way to compose and review.

Both cameras feature a fixed 3-inch LCD, which is quite standard for compacts of this era. The Olympus TG-810 scores higher on resolution with 920k dots compared to Pentax’s 460k dots. This difference is tangible: Olympus’ display renders a sharper, more detailed preview, which is welcome when shooting outdoors under bright sunlight, though glare is still a challenge.

Pentax uses a widescreen TFT with anti-reflective coating, which helps somewhat against reflections, but the lower resolution can frustrate when checking fine focus or image details.

Neither camera offers an electronic viewfinder, so if you prefer composing with your eye to the screen, you'll need to adapt or consider alternative models.

The lack of touchscreen on both may feel dated today but reflects their 2011-2012 heritage; was my first thought until recalling how impractical touchscreens can be with wet fingers or gloves.

Overall, Olympus edges out slightly in display usability due to higher resolution, making it better suited for composition and review in variable lighting.

Unlocking the Sensor: Image Quality Basics

At the heart of any camera is the sensor - the gatekeeper of image quality.

Both cameras pack a classic 1/2.3-inch sensor, a typical size for compact cameras of this era, with roughly the same physical dimensions (6.17 x 4.55 mm). However, they differ in sensor technologies and megapixels.

• Olympus TG-810: Uses a 14-megapixel CCD sensor with an anti-aliasing filter.
• Pentax WG-2 GPS: Upgrades to a 16-megapixel BSI-CMOS sensor with anti-aliasing filter.

Here, Pentax holds a theoretical advantage with a CMOS sensor, which traditionally offers better noise performance, especially at higher ISO levels, due to backside illumination (BSI) technology. Olympus relies on CCD, which often has excellent color rendition but can falter in low-light.

Testing confirms this: the Pentax yields cleaner high-ISO images - usable even at ISO 6400, which is the max native ISO on the WG-2 GPS. Olympus tops out at ISO 1600 native, with noticeable noise creeping in beyond ISO 400.

Both have a maximum resolution of 4288 x 3216 pixels, which is plenty for prints, but the Pentax slightly edges out on detail retention at base ISO thanks to the sensor design.

For those wondering, neither camera offers RAW support, limiting post-processing flexibility - a crucial factor for professionals or enthusiasts wanting to extract maximum image quality.

Crystal Clear or Soft Focus? Autofocus and Focus Precision

Next, let’s examine autofocus (AF) systems - key for quick or unpredictable shooting, especially outdoors.

Olympus TG-810 leans on contrast-detection AF with face detection and some degree of tracking (though the number of focus points isn’t officially disclosed). Pentax WG-2 GPS packs 9 AF points with contrast detection and face detection too, but offers manual focusing, a rarity in rugged compacts, giving better control for creative close-ups or macro shots.

A quick field test comparing AF speed and reliability finds that Pentax’s AF feels snappier and more precise, especially in good light. Olympus occasionally hunts in dimmer environments and macro, presumably limited by its older CCD and simpler focus system.

That brings us to macro capabilities: Olympus starts focusing from 3 cm while Pentax reaches a very respectable 1 cm - meaning you can get truly close-up details with the WG-2 GPS.

One drawback: Olympus does offer sensor-shift image stabilization (IS), enhancing handheld shots in low light or close range. Pentax surprisingly lacks built-in stabilization, which may lead to more blur under shaky or low-light conditions.

Let’s Shoot: Lens, Zoom, and Aperture Versatility

Both cameras feature fixed lenses with a 28-140mm equivalent zoom range - a 5x optical zoom, ideal for versatile outdoor framing.

Pentax’s lens typically has a slightly faster max aperture: F3.5-5.5 versus Olympus' F3.9-5.9. This gives Pentax a slight edge in gathering light at the wide end.

Neither camera has interchangeable lenses, which is typical for waterproof compacts, so optical quality and versatility come down to the built-in glass.

In practice, both lenses produce decent sharpness across the zoom range, although Pentax edges ahead with crisper images, especially at the telephoto end, likely due to newer optics and sensor combo.

Still Images and Color Science: What Do the Files Look Like?

Looking at sample images side-by-side reveals some telling differences:

• Olympus TG-810: Colors tend to be warm and slightly saturated, pleasing for snapshots but occasionally oversaturated for skin tones. Dynamic range feels limited, with shadows losing detail quickly in high contrast scenes.
• Pentax WG-2 GPS: Produces more neutral colors with better exposure latitude, which suits landscape or outdoor scenes requiring detail preservation. Skin tones are more natural.

Both cameras struggle with noise and softness above ISO 800, meaning you should try to shoot in good lighting.

Interestingly, Olympus’s image stabilization helps handheld shots be sharper in less light, but Pentax’s superior macro focusing and lens speed pull ahead in close-up scenes.

Shooting Video: How Do They Capture Motion?

For those who dabble in video, neither model is a powerhouse, but Pentax pulls ahead here.

• Olympus TG-810: Records HD video at 1280 x 720 px at 30 fps.
• Pentax WG-2 GPS: Offers Full HD 1080p at 30fps and 720p at 60fps, giving smoother slow-motion options.

Neither supports external microphones or headphones, so audio quality remains basic and typically captures ambient noise.

Both lack advanced video stabilization and manual video controls, so consider them as secondary video options rather than dedicated movie cameras.

Battery Life, Storage, and Connectivity – The Long Haul

For field and adventure photographers, battery life and storage flexibility can make or break the experience.

• Olympus TG-810: Rated for about 220 shots per charge with a proprietary LI-50B battery.
• Pentax WG-2 GPS: Slightly better at 260 shots per charge using the D-LI92 battery.

Neither is stellar by today’s DSLR or mirrorless standards but reasonable for compact waterproof cameras. Investing in spare batteries is a good idea.

Storage-wise, both take standard SD/SDHC/SDXC cards and have single slots. Pentax offers additional internal memory, a handy fallback if your card fails.

Wireless connectivity is similar; both support Eye-Fi cards for Wi-Fi transfer (a bit dated now), but no Bluetooth or NFC.

Environmental Durability: How Rugged Are They Really?

Here’s where they earn their keep. Both cameras are aimed squarely at rugged use, but with slightly different tolerances.

Pentax clearly wins on crushproofing, making it more suitable for construction sites or rugged terrains where your camera might get squished.

The built-in GPS on both is a boon for geo-tagging, perfect for travel or documenting precise locations.
