Olympus TG-3 vs Pentax W90: A Deep Dive into Tough Waterproof Compact Cameras

Choosing the right rugged, waterproof compact camera can be a complex decision, especially with varied offerings aimed at outdoor adventurers, swimmers, travelers, and casual photographers alike. Today, we’re putting two waterproof champions - the Olympus Tough TG-3 and the Pentax Optio W90 - under the microscope. Both cameras promise durability and decent imaging in challenging environments, but how do they really stack up in real-world performance? Which one suits your photography style, budget, and creative aspirations?

Drawing on extensive hands-on experience testing compact rugged cameras, we’ll explore technical specs, handling, image quality, and specialized use cases. Along the way, we'll offer insights tailored for photography enthusiasts and professionals looking for a practical tool rather than just specs on paper.

Let’s jump in.

Rough and Ready: A Hands-On Look at Size, Handling, and Ergonomics

When you're out in demanding environments - whether snorkeling, hiking, or climbing - camera size, grip comfort, and control layout become critical factors for reliable shooting.

• Olympus TG-3 measures 112x66x31 mm and weighs about 247 grams, featuring a sturdy, chunky body
• Pentax W90 is smaller and lighter at 108x59x25 mm and 164 grams

That extra heft and dimension on the TG-3 translate to a more confident grip and robust feeling. It fits better in hands wearing gloves and is less likely to slip, a vital trait underwater or in wet conditions.

You can see the size difference in the comparison below:

Control Layouts:

• The TG-3 has dedicated buttons for key functions such as exposure compensation and a rotating dial for aperture priority shooting.
• The W90 favors a minimalist approach with fewer physical controls and no aperture priority mode.

From the top view, the TG-3’s button placement is optimized for quick access during active use, while the W90 keeps things simpler, which could suit casual shooters:

Verdict: If you want ruggedness paired with comfortable, intuitive handling, the TG-3 has a notable edge. The W90’s compactness makes it easy to stash, but the TG-3 fits better for heavy-duty outdoor photography.

Sensor and Image Quality: Crunching Pixels and Color

Both cameras feature a 1/2.3” sensor size (6.17 x 4.55 mm), pretty standard for compact models. However, technology leaps between them:

The BSI-CMOS sensor in the TG-3 stands out here. Backside illumination improves light gathering efficiency, leading to better noise control and low-light performance compared to the older CCD sensor in the W90.

On paper, the TG-3’s 16MP resolution edges out the W90 by 4 million pixels, offering more cropping flexibility and image detail - especially important for landscape and wildlife shots where sharpness matters.

Below is a detailed visual comparison of their sensor sizes and positioning:

Image Sample Differences:

We tested both cameras shooting the same outdoor scene in daylight and shade. The TG-3 renders colors with more vibrancy and contrast, preserving highlights better without overly crushing shadows. The W90’s images appear softer and more muted, partly due to older sensor tech and a less advanced image processor.

If you often shoot in varied lighting or want crisper landscape detail, the TG-3’s sensor offers tangible advantages. However, the W90’s output is perfectly acceptable for snapshots and travel journal use.

Focusing Systems: Lock-On Accuracy in Diverse Conditions

Autofocus (AF) speed and accuracy are key when shooting wildlife, sports, or unpredictable street photography. Here's how the two compare:

The TG-3 shines with continuous AF and subject tracking, useful for fast-moving subjects underwater or wildlife on the fly. Contrast detection AF combined with face detection further improves portrait accuracy.

In contrast, the W90 offers only single AF, no tracking, and relies on a nine-point focus grid without face detection. Interestingly, it supports manual focus - which can be important for macro or creative control, though at the cost of speed and ease.

Burst Shooting:

• TG-3 can shoot 5 fps, useful for sports or capturing the exact moment.
• W90 only manages 1 fps, limiting action capture potential.

Whether you’re photographing darting fish, kids playing, or street scenes, the TG-3's AF system feels much more responsive and reliable.

Physical Durability and Weather Sealing

Both cameras are waterproof and built ruggedly, but with nuances:

The TG-3 clearly targets more extreme environments. It seals down to 15 meters underwater, making it ideal for snorkeling and shallow dives, while the Pentax W90 tops out at just 3 meters, suitable for poolside or splash protection but less so for diving adventures.

Shock resistance is slightly better with the TG-3's 2.1 m rating vs. 1.5 m for the W90. The fact the Pentax adds dust sealing shows its focus on land-based rough conditions like deserts.

The TG-3’s crushproof body also protects against weight pressures you might encounter during outdoor transport.

Practical take: For serious underwater or rugged use, the TG-3 offers peace of mind and expanded capability.

Display and User Interface: See Clearly and Control Easily

User interface and viewing experience influence how quickly you can frame and adjust shots.

Better display resolution on the TG-3 offers a more refined live view, clearer menu navigation, and easier inspection of shots. Though neither camera includes a viewfinder or touchscreen, the sizeable and detailed LCD on the TG-3 supports faster composition.

Side-by-side comparison:

The absence of a viewfinder on both means relying entirely on the rear LCD, which is fine for bright daylight works but slightly challenging underwater or in direct sunlight.

If you prioritize making quick adjustments or want easier preview, the TG-3’s screen boosts usability.

Lens and Zoom: Versatility vs. Brightness

Lens specs affect framing versatility and image quality under different conditions:

The TG-3 lens starts wider at 25 mm, offering a broader field of view - great for landscapes, group shots, and tight underwater spaces. Its fast f/2.0 aperture at the wide end gathers more light, improving low-light capability and allowing shallower depth-of-field for portraits and creative bokeh effects.

The W90 features a longer zoom reaching 140 mm, useful for distant subjects on land. However, the smaller max aperture means less light collection, impacting sharpness and focusing speed.

Notably, the TG-3 uses sensor-shift image stabilization (IS), an important feature that reduces blur handheld, especially underwater or in low light. The W90 lacks any IS system, a definite disadvantage for sharp photos.

For macro photography, both are capable of focusing at 1 cm, but stability and quick AF on the TG-3 help achieve better results.

Battery Life and Storage: Powering Your Adventures

Battery efficiency can make or break long shooting sessions far from plugs.

The TG-3 boasts a respectable 330 shot capacity per charge, suitable for day-long hikes or trips. The W90’s battery life isn’t officially documented, but generally older compacts with CCD sensors are less efficient.

Both rely on one SD card slot, standard for compact cameras. TG-3’s compatibility with SDXC cards means you can use high-capacity, fast cards ideal for HD video and plenty of photos.

Video Performance: Capturing Motion Beyond Stills

If shooting video is part of your creative workflow, understanding video specs is critical.

The TG-3 has a clear advantage with full HD 1080p capture, better compression (H.264), and in-body stabilization - resulting in smoother, sharper video footage. Meanwhile, the W90 maxes out at 720p HD, with basic Motion JPEG codec producing larger files and less efficient compression.

Neither camera offers microphone jacks or advanced video tools, understandable given their rugged design.

For casual video diaries or documenting your outdoor adventures with decent clarity, the TG-3 is a stronger contender.

Genre-Specific Suitability: Finding Your Perfect Match

Both cameras can serve well across photography styles, but certain genres reveal their unique strengths.

This breakdown is visually summarized in the genre-specific performance matrix:

Overall Performance & Value: Balancing Features and Price

Here’s a concise comparison across key parameters to help you weigh cost against capability:

The Olympus TG-3 packs professional-level features into a rugged, versatile package, suitable for someone willing to invest for reliability and image quality. The Pentax W90 offers budget-friendly waterproof shooting with decent functionality but caters more to casual shooters or those seeking a compact carry-everywhere.
