Olympus E-330 vs Pentax WG-1 GPS: A Hands-On Comparison of Two Distinct Cameras for Distinct Needs

Choosing a camera is a journey packed with tradeoffs and decisions, especially when you pit two very different beasts side by side like the Olympus E-330 DSLR and the rugged Pentax WG-1 GPS compact. I’ve spent a solid chunk of my career testing both entry-level and advanced cameras, and while these two models were launched in different eras and target completely different users, comparing them provides great insight into how varied photography needs can be - and how your choice today reflects that.

In this detailed comparison, I’ll take you through the full spectrum - covering technical specs, practical photography scenarios, user ergonomics, and value for money. Whether you’re a serious enthusiast deciding on stepping into DSLRs or a go-anywhere adventure shooter seeking durability over complexity, this article will help you understand what each camera brings to the table.

First Impressions: Size, Feel, and Handling

Before diving into specs, the first thing you notice - and keep noticing - is how different these cameras are physically. The Olympus E-330 weighs 616g and sports a mid-size DSLR body typical of the mid-2000s. The Pentax WG-1 GPS is a petite, lightweight compact weighing only 167g with fully ruggedized bodywork.

You can see the Olympus E-330’s DSLR bulk compared to the Pentax WG-1 GPS’s ultra-compact, splash-proof design.

Ergonomics and Grip: The E-330 offers a solid grip that fits well in the hand, with physical dials and buttons for quick adjustments - very useful when shooting manually. I’ve always appreciated Olympus's approach to button layout; though somewhat dated now, it was pretty user-friendly back in 2006.

In contrast, the WG-1 GPS is all about portability and toughness. It slips easily into a pocket or strap-mounted pouch and feels like a champ in challenging environments. However, the tradeoff is smaller controls that might feel fiddly for anyone with large hands or while wearing gloves.

Under the Hood: Sensor and Image Quality Comparison

At the heart of any camera’s image quality are its sensor characteristics. The Olympus E-330 houses a 4/3 CMOS sensor measuring 17.3 x 13 mm with a resolution of 7 megapixels. This was quite respectable back in 2006 for an entry-level DSLR. The Pentax WG-1 GPS, released in 2011, has a much smaller 1/2.3" CCD sensor sized 6.17 x 4.55 mm but compensates with a higher resolution of 14 megapixels.

Note the significant sensor size difference, with Olympus’s sensor area about 8x larger.

In practical terms:

• Olympus E-330: Larger sensor means better light gathering ability, reduced noise, and overall superior image quality especially in low light. The 4/3 size sensor remained a sweet spot for good dynamic range and moderate depth-of-field control. The native ISO maxes out at 400, boost to 1600, limiting noise performance but still decent for the era.

• Pentax WG-1 GPS: Smaller sensor but higher pixel count means more detail in good light but significantly more noise in low light. ISO capability is much broader (up to 6400), but don’t expect stellar results at the top end. Its strength lies in daylight shooting, where its zoom lens and sensor can deliver punchy, sharp results.

In my controlled lab tests, the E-330 excels with smoother gradations and less chroma noise at ISO 400 compared to the WG-1 GPS’s noisier 800 ISO images.

LCD Screen and Viewfinder: Composing Your Shot

The Olympus packs a 2.5” tilting LCD with 215K dots - respectable for its time and useful when shooting at tricky angles. The WG-1 GPS features a 2.7” fixed TFT LCD with slightly higher 230K dots and an anti-reflective coating, making it easier to use in bright sunlight.

The Olympus's tilting screen gives compositional flexibility; the WG-1 GPS’s fixed screen is bright and glare-resistant.

One big difference: The E-330 sports an optical pentamirror viewfinder offering approx. 95% coverage with 0.47x magnification, giving traditional DSLR framing accuracy and stability under bright conditions. The WG-1 GPS replaces this with no viewfinder at all, relying solely on its LCD.

Being a seasoned DSLR user, I find the optical viewfinder invaluable for prolonged shooting and precise framing, especially in direct sunlight or fast action. The WG-1 GPS’s LCD-only approach suits its casual, field-ready ethos but can be limiting during quick moves or bright conditions.

Autofocus Performance and Shooting Dynamics

Autofocus (AF) can make or break your experience, especially for moving subjects and spontaneous moments. The Olympus E-330 uses a contrast of phase detection AF with 3 selectable focus points, supporting AF-C (continuous) and AF-S (single) modes.

By comparison, the Pentax WG-1 GPS uses contrast-detection AF with 9 focus points and claims some AF tracking functionality, but no continuous AF; it’s generally slower and less reliable in tricky light or fast action.

From my field tests:

• The E-330's autofocus is quick and accurate for indoor portraits and landscapes but less suited for sports or wildlife where subject tracking is important. The 3-point system combined with its reasonable burst rate (3 fps) means you can capture some action but with limitations.

• The WG-1 GPS autofocus is much slower due to its small sensor and simpler processor, focusing best in bright daylight. Its burst rate is sluggish at 1 fps, making it ill-suited for fast-paced photography.

Neither camera offers face detection or eye AF - a feature we now consider standard for portrait work - but considering their release dates, this is not surprising.

Exploring Photography Genres

Here’s where we dig into how each camera fares in different photographic disciplines. I’ve tried both cameras extensively in real-world conditions reflecting the reality of everyday photography.

Portrait Photography

Portraits demand skin tone accuracy, depth-of-field control, and eye detection for best results. The Olympus E-330’s larger Four Thirds sensor and ability to use interchangeable lenses (the E-330 supports the Micro Four Thirds mount with some adapters, but originally Olympus's proprietary four-thirds lenses) give you flexibility to achieve attractive bokeh and better background separation.

The Pentax WG-1 GPS, with its fixed 28-140mm equivalent lens and smaller sensor, struggles with shallow depth of field. Your portraits will be more snapshot-like, with more background in focus, which might be okay for casual prints.

Neither camera supports face or eye detection autofocus, so manual composition and focus confirmation are necessary.

Landscape Photography

Landscape photography benefits from high resolution, dynamic range, and often weather sealing.

• The E-330’s 7MP is modest by today’s standards but offers respectable color depth and a larger sensor area. Its body is not weather sealed, so shooting in inclement weather requires care.

• The WG-1’s smaller sensor is less capable in dynamic range and struggles with noise in darker areas. However, the camera’s environmental sealing, waterproof rating, dustproofing, shockproofing, and freezeproofing give it an edge in rugged situations where rain or dirt is a factor.

While the Olympus is capable of producing cleaner, more detailed landscape images, the WG-1 GPS shines as a tough companion on hikes, misty shorelines, and snowy treks.

Wildlife Photography

Wildlife demands good telephoto reach, fast continuous shooting, and reliable autofocus tracking.

• Olympus E-330: The lens mount allows you to fit telephotos (with a 2.1x crop factor), but the standard 7MP resolution limits cropping flexibility. The burst rate of 3fps is modest, allowing for limited action sequences. The 3-point AF system is not ideal for smoothly tracking rapid wildlife movement.

• Pentax WG-1 GPS: Its 28-140mm (5x zoom) lens extends reach nicely for general wildlife, but the camera’s 1 fps burst rate and slower AF undermine capturing fast-moving subjects.

In practice, neither camera excels for serious wildlife, but Olympus offers more potential with interchangeable lenses and better AF.

Sports Photography

Sports mirror wildlife’s speed and precision demands, with extra emphasis on low light.

The Olympus E-330 can handle indoor sports moderately due to aperture priority and manual exposure modes. Its maximum shutter speed of 1/4000s and ISO 400 native (boost 1600) settings give decent flexibility.

The WG-1 GPS is much less capable here, lacking advanced exposure modes and offering max shutter speed of 1/1500s only.

Street Photography

Street shooters prize portability, discretion, and quick responsiveness.

• WG-1 GPS’s compact size and robust body make it unobtrusive and ready for spontaneous shots even in wet urban conditions.

• Olympus E-330 is bulkier and draws more attention but gives higher image quality and manual controls for creative street portraits and night shots.

Macro and Close-Up Work

Macro shooting requires close focusing distance and fine AF precision.

The Pentax WG-1 GPS excels here with a macro capability down to 1cm, making it great for flower or insect close-ups without extra accessories.

The Olympus E-330 lacks a dedicated macro feature, relying on compatible macro lenses. While more versatile, it requires investment in lenses and skill.

Night and Astrophotography

Low light is where sensor size and ISO performance count most:

• The E-330’s ISO ceiling is 400 native and 1600 boosted - modest by today’s standards - and its noise control is limited.

• The WG-1 supports ISO up to 6400 but suffers heavy noise at higher settings due to smaller sensor.

Neither camera is ideal for astrophotography - long exposures and manual controls can be cumbersome for beginners on these models.

Video Capabilities

Video is lightweight on both:

• Olympus E-330: No video recording capabilities.

• Pentax WG-1 GPS: Can shoot 720p HD video at 30fps using Motion JPEG codec, not suitable for professional video but fine for quick clips.

Travel and Adventure: Versatility and Durability

If traveling light, the WG-1 GPS’s ruggedness, waterproofing and slim profile make it a no-brainer for outdoor enthusiasts. Its built-in GPS is handy for geographical tagging - great when documenting trips.

The Olympus E-330 offers classic DSLR versatility with superior image quality but demands more gear and careful handling.

Battery life on the WG-1 GPS is reasonably good at 260 shots per charge; the E-330’s battery life figures are undocumented here, but expect around 350-400 shots given its DSLR type and era.

Professional Use and Workflow Integration

Here’s where the Olympus shines:

• Supports RAW files allowing extensive post-processing, critical for professionals and advanced enthusiasts.

• Offers manual focus, shutter speed, aperture control, exposure compensation, and lens versatility.

• Supports Compact Flash and xD cards, enabling flexible storage.

The Pentax WG-1 GPS shoots only JPEGs, severely limiting professional workflow applicability. Its fixed lens and simplified controls confirm it’s aimed at casual users.

Build Quality and Weather Resistance

If your photography involves rough conditions, the WG-1 GPS’s environmental sealing is outstanding - rated to withstand water, dust, shock, crush, and freeze conditions.

The Olympus E-330 lacks weather sealing, so it demands more care in adverse environments.

Connectivity and Storage

The Olympus E-330 offers USB 1.0 connectivity - very slow by today’s standards and no wireless features.

The WG-1 GPS upgrades to USB 2.0, has HDMI output for viewing, and supports Eye-Fi wireless card for image transfer, a plus in field use.

Price and Value Assessment

At launch, the Olympus E-330 was priced near $1100, commanding its place as a serious amateur DSLR.
