Nikon Coolpix P330 vs Pentax Optio WG-2 GPS: The Compact Camera Face-Off for Enthusiasts and Pros

In the ever-evolving arena of compact cameras, two intriguing contenders come into focus: the Nikon Coolpix P330, a compact designed to impress with its image quality and manual controls, and the Pentax Optio WG-2 GPS, a robust waterproof warrior ready to get down and dirty with Mother Nature. Both cameras emerged around the early 2010s and are targeted at very different user needs - yet many photography enthusiasts find themselves eyeballing both for their next step beyond smartphones or as a durable travel companion.

After clocking in hours of hands-on testing across varied photo scenarios - from crisp landscapes to challenging low light, and even a splash or two in natural water - the findings revealed a rich tapestry of strengths and compromises unique to each model. Dive in as we unpack this head-to-head comparison, laying out image quality, usability, versatility, and value to help you decide which one suits your creative ambitions best.

Size, Handling, and Ergonomics: Compact Versus Cunningly Rugged

Let’s talk feel - that tactile sensation when you hold a camera, which often sets the tone for shooting enjoyment and precision. The Nikon P330 is a classic compact with refined styling and a manageable footprint, whereas the Pentax WG-2 GPS is engineered more like a small tank, boasting rugged defense against the elements.

Weighing in at nearly identical heft - 200 grams for the P330 and 198 grams for the WG-2 GPS - there’s little to separate them on the scale. But the physical dimensions tell a different story: Nikon’s 103 x 58 x 32 mm body is slightly slimmer and shorter than the Pentax’s 122 x 61 x 30 mm frame. The WG-2 feels chunkier in hand, bolstered by thick rubberized grips and sealed buttons designed to endure dust, shocks, and water immersion up to 12 meters.

In my experience, the P330’s more traditional ergonomics favor street and portrait photographers who appreciate a discreet camera that slips into pockets and balances well during extended handheld shooting. Pentax’s robustness, meanwhile, offers peace of mind for adventure seekers shooting on hikes, underwater, or dusty landscapes, where dropping your camera isn’t a catastrophic disaster.

Both lack an electronic viewfinder, relying instead on 3-inch LCDs - more on those screens shortly.

Understanding the Control Layout: Simplicity Meets Expedition-Ready

Form meets function in the button configurations and top-panel design, critical for intuitive operation - especially when you’re knee-deep in a shoot.

Nikon’s P330 is a classic enthusiast compact, sporting a clean layout: a straightforward mode dial including aperture- and shutter-priority modes, exposure compensation, and a dedicated command dial on the back. This arrangement invites seasoned users to nudge settings with minimal menu diving, a genuine blessing when fast reflexes are needed.

In contrast, Pentax’s WG-2 GPS has a more utilitarian control setup, emphasizing waterproof sealing at the expense of tactile refinement. Its buttons are large and somewhat resistant to press - a necessary evil given its toughened façade. Exposure modes are fewer, primarily automatic or scene-based, with limited manual override options. The tradeoff is clear: simplicity and protection over granular control.

If you prize manual photography control and speedy adjustments, the Nikon shines here. For rugged terrain shooters who want quick auto modes without fuss, the Pentax feels more natural.

Sensor Size and Image Quality: Bigger Isn’t Always Better, But It Helps

Now we get to the crux: image quality. Sensor size, resolution, and processing are king when it comes to crisp photos with good dynamic range and pleasant noise characteristics.

Nikon’s P330 rocks a 1/1.7-inch BSI-CMOS sensor measuring 7.44 x 5.58 mm (41.52 mm²), with a modest 12-megapixel resolution. Pentax’s WG-2 GPS carries a smaller 1/2.3-inch BSI-CMOS sensor at 6.17 x 4.55 mm (28.07 mm²), with a higher 16-megapixel count. At first glance, Pentax’s greater resolution sounds appealing, but sensor physics tells a story of trade-offs: smaller sensor area means smaller individual pixels, generally leading to higher noise at elevated ISOs and reduced dynamic range.

This aligns with my practical testing and DxOMark results - which, interestingly, only assessed the P330 with an overall score of 54. Nikon’s sensor boasts stronger color depth (21-bit vs unknown for Pentax), dynamic range (~11.7 EV), and better low-light ISO performance. While the WG-2 GPS supplies no tested DxOMark data, real-world photos show more visible noise and less detail retention in shadow and highlight areas compared to the P330.

Pentax’s sensor does enable respectable resolution and fine detail in bright conditions, but struggles more visibly when lighting deteriorates.

Screen and Interface: Visual Comfort and Usability

Both cameras share similar LCD screen sizes, but their quality and user-friendliness diverge sharply.

Nikon’s P330 sports a 3-inch, 921k-dot TFT-LCD with decent brightness and contrast for framing and reviewing shots in varied lighting. Unfortunately, it’s a fixed screen without touch capability, so menu navigation relies purely on physical buttons, which can slow down workflow somewhat.

Pentax’s WG-2 GPS has a 3-inch 460k-dot widescreen TFT LCD featuring an anti-reflective coating - a smart choice for shooting in direct sunlight during outdoor adventures. The lower resolution means images don’t look as sharp on the screen, but the anti-glare treatment improves usability in bright environments.

Neither model uses touchscreens, an omission at this price point reflecting their era and priorities. Both could benefit from tilting or articulating rear screens, especially for low or overhead shooting angles - another reminder that these are essentially point-and-shoot compacts, not mirrorless era trailblazers.

Zoom Lenses, Aperture, and Focusing: The Eye’s Extension

Lens quality and autofocus performance are critical, especially for genres such as wildlife and macro photography.

On paper, the Nikon’s lens covers 24-120mm equivalent (a 5x zoom) with a relatively bright aperture range of f/1.8 to f/5.6, which is quite fast for a compact camera. The wide f/1.8 aperture at the short end makes it a winner for low-light scenarios and offers improved depth of field control, letting you achieve more pleasing background bokeh, especially in portraits. Nikon’s contrast-detection AF system includes face detection but lacks continuous AF during video and burst shooting.

The Pentax WG-2 GPS’s 28-140mm lens (5x zoom) has an aperture range of f/3.5 to f/5.5, less bright and thus more limited in low-light capability. However, Pentax scores on macro with a close focus distance of 1 cm, letting you get seriously close-up, while Nikon is limited to 3 cm - which makes a difference if you shoot flowers or textures often. On focusing, Pentax has nine autofocus points, including multi-area and single AF modes, and face detection. However, it lacks continuous AF options.

In practice, Nikon’s faster lens means punchier images in dim environments and a smoother out-of-focus area, complementing its sensor strengths. Pentax’s macro reach is remarkable for a rugged compact, though the slower lens hampers some creative flex.

Burst, Shutter, and Speed: Catching the Moment

If you’re chasing action - wildlife, sports, or street moments - burst rate and shutter responsiveness matter.

Nikon P330 features a commendable 10 fps continuous shooting at full resolution, with shutter speeds ranging from 1/60 to 1/4000 second, giving you flexibility in freezing action or experimenting with motion blur. The camera supports shutter and aperture priority and manual exposure modes, allowing creative control over depth and motion effects.

Conversely, Pentax WG-2 GPS offers a much slower 1 fps continuous shooting rate and shutter speeds from 4 seconds up to 1/4000 sec, but no aperture or shutter priority control - only automatic selections based on scene modes. This severely limits sports or fast action capabilities. However, it gains a timelapse recording function not found on the P330, which could attract landscape timelapse enthusiasts.

If your work demands fast bursts and manual control, Nikon pulls ahead.

Weatherproofing and Durability: When the Going Gets Tough

Pentax triumphs with an impressive suite of environmental protections. Its camera body is waterproof to 12 meters, dustproof, shockproof, crushproof, and even freezeproof. For underwater hiking, snorkeling, or extreme outdoor adventures, this reliability is invaluable. Nikon P330, however, has no weather sealing - meaning a rainstorm or accidental dunk risks immediate damage.

This is where ergonomics and protection intersect palpably in Pentax’s favor. Its sealed buttons and sturdy build make it ideal for rough-and-tumble use, offered at a notably lower price tag as well.

Video Capabilities: Which Camera Moves Better?

Both cameras support Full HD video at 1080p, but with different frame rate options and flexibility.

Nikon’s P330 records 1920x1080 video at up to 60 fps, delivering smoother motion capture, and also shoots 720p at 30 or 25 fps. Video is encoded in MPEG-4/H.264 formats. Unfortunately, it lacks microphone and headphone jacks and optical image stabilization, making it less ideal for serious video work.

Pentax WG-2 GPS shoots 1080p at 30 fps max, with additional 720p at 60 fps to 30 fps options, and also records timelapse video. Pentax wins on video stabilization here, offering no dedicated image stabilization system - which might produce shakier handheld footage.

Neither camera is a video powerhouse, but Nikon’s higher frame rate options give it a slight edge for smooth, casual shooting.

Battery Life and Storage: How Long and Where?

The Nikon P330 uses an EN-EL12 battery rated for approximately 200 shots per charge, while the Pentax WG-2 GPS’s D-LI92 battery extends slightly to around 260 shots. Both cameras take SD/SDHC/SDXC cards for storage.

In field tests, battery life for both shows limits for full-day shooting without extras, but the Pentax’s slight edge and ruggedness encourage carrying at least one spare for longer outdoor adventures.

On connectivity, both cameras fall short - no built-in Wi-Fi or Bluetooth, although Pentax supports Eye-Fi card-based wireless transfers, a somewhat outdated solution.

Price and Value Proposition: What Does Your Dollar Buy?

With an MSRP around $500 at launch for the Nikon P330 and roughly $300 for the Pentax WG-2 GPS, price tags highlight their market positioning: Nikon pitches to enthusiasts who want compact sophistication; Pentax targets rugged adventurers who need durability over refinement.

For photography enthusiasts on a budget seeking image quality, manual controls, and low-light ability, the P330 justifies its premium. If your priority is a camera that withstands rough conditions with macro capabilities and GPS tagging, at an affordable price, Pentax is compelling.
