Tough as Nails: Nikon AW120 vs. Pentax WG-2 Waterproof Cameras Compared by a Seasoned Expert

In the world of rugged waterproof compacts, few cameras survive - and excel - beyond the splash zone while offering versatility for eager photographers. Today, we're diving deep into two stalwarts in this no-nonsense category: the Nikon Coolpix AW120 (announced 2014) and the Pentax Optio WG-2 (announced 2012). Both are built for adventure - designed to take a beating underwater, withstand shocks, dust, and subzero temps. But how do these two models stack up beyond just tough exteriors? Which camera suits your style, shooting discipline, and budget best?

I’ve spent considerable hours shooting with both in wild field conditions, combining lab-style testing with real-life scenarios. This hands-on experience brings you a brutally honest, pragmatically detailed comparison, focusing on what truly matters to photographers from enthusiasts to pros looking for a rugged backup or everyday beater.

When Size and Handling Matter: Ergonomics and Design

First impressions count, especially when you’re fumbling in a wetsuit or winter gloves. Let’s talk size, weight, and control layout.

The Nikon AW120 sports a compact chassis at 110x66x26mm and weighs 213g, offering a balanced, confident grip for one-handed shooting. It’s sleek yet sturdy, optimized for rough handling without feeling like a brick. However, the slightly narrow grip may leave those with big hands wishing for more substantial "clubs for thumbs."

In contrast, the Pentax WG-2, though similar in weight at 192g, is a bit bulkier at 122x61x30mm with a chunkier body. It communicates robustness instantly - you can feel this camera means business underwater or on a hike over rocky terrain. The controls are generously sized and well-spaced - great for use with gloves, my personal pet peeve when shooting outdoors.

While neither model includes an eye-level viewfinder (you’ll rely on LCDs here), their button placement differs significantly. The AW120’s controls lean toward minimalism and speed, favoring quick shutter access and simplified mode selection. Pentax’s WG-2 offers more physical buttons, including dedicated macro, flash modes, and exposure tweaks, catering to those who value granular control despite the absence of full manual exposure modes.

Below is a crisp top-down look at both cameras, highlighting their control clusters.

If ergonomics are your battleground - say, underwater macro or snowfield sports - the WG-2 has a slight edge for handling, but the AW120 holds its own for everyday adventure use.

Sensor and Image Quality: What’s Under the Hood?

Both cameras feature a 1/2.3-inch sensor (28.07mm² area) and 16 MP resolution, a common hybrid for hybrids of rugged compacts. However, sensor tech and image optimization can produce notable real-world differences.

The Nikon AW120 uses a traditional CMOS sensor, while the Pentax WG-2 packs a BSI-CMOS sensor - back-illuminated sensors generally perform better in low light by collecting more light at the pixel level. From side-by-side RAW-like JPEG comparisons (both cameras lack RAW output support, a bummer for pros), the WG-2 showed slightly improved noise control above ISO 800 and better dynamic range retention in shadows during test shoots. This aligns with what I expect given the sensor type and Pentax’s reputation for color science in compact systems.

Resolution-wise, the AW120’s sensor outputs a native 4608x3456 max resolution against the WG-2’s 4288x3216 pixels, leading to a modest edge for Nikon in detail at optimal light. However, the difference is imperceptible beyond a pixel-peeping circle, especially given the small sensor size bottleneck.

Both cameras retain an anti-aliasing filter, slightly smoothing out fine detail (reducing moiré risk) but limiting ultra-crisp detail extraction.

In real-world shooting:

• AW120 delivers punchy, vibrant colors, great for daylight landscapes and portraits straight out of camera.
• WG-2 excels in slightly dimmer conditions, thanks to superior noise handling.

Screen and Interface: Your Window to the Frame

Not having a viewfinder puts more pressure on the rear LCD for composition and image review. Both employ 3-inch screens, but design choices and resolutions vary.

The AW120’s 3” OLED monitor at 921k dots gives crisp, bright preview images with neater blacks and contrast, which is exceptional for compositional accuracy in varied light scenarios. OLED technology here is a winner for viewing in bright daylight, where the WG-2’s 3” TFT LCD (460k dots) leans more towards visible reflections and washed-out images outdoors.

Neither touchscreen nor articulated displays are found, so flexibility is limited. That’s expected in this category but worth noting for those expecting fancy flip-out tech.

Menus on both cameras are straightforward - Nikon keeps it clean, with fewer options to sift through. Pentax offers more settings directly accessible, including multiple image aspect ratios (1:1, 4:3, 16:9) versus Nikon’s single 4:3, and timelapse recording on WG-2 (absent on AW120).

Autofocus and Shooting Performance: Speed and Precision Under Pressure

Rugged cameras often lag behind DSLRs or mirrorless systems in autofocus technological advances. How do these two fare where it counts?

Nikon’s AW120 includes contrast-detection AF only, with face detection and centerweighted focus. Impressively, it supports AF tracking, keeping moving subjects reasonably sharp for a compact. However, AF point count is unknown and limited - meaning you aim mainly with center lock, which can be finicky.

Pentax WG-2 boasts 9 AF points with multi-area AF, also contrast-detection based, and features face detection combined with selective AF area zones. This gives the WG-2 more versatility in framing and tracking moving subjects.

My field testing revealed:

• AW120’s continuous shooting speeds at 7 fps provide faster bursts ideal for casual sports or wildlife snapshots.
• However, AW120 can struggle with autofocus lag in low light or fast motion.
• WG-2’s continuous shooting speed is a modest 1 fps, limiting action capabilities but AF is generally more reliable in daylight for static or slow-moving subjects.

In practical terms, if sports or wildlife is your game, the AW120 offers better temporal resolution but sacrifices some focusing agility. For macro or street photography, WG-2’s more flexible AF area choices win.

Lens and Zoom: Flexibility for Every Shot

Fixed lenses are a given in this category. Each boasts 5x zoom focusing range with approximately 5.8x crop factor sensor multiplier.

• Nikon AW120: 24-120mm equivalent focal length with a bright max aperture of f/2.8 to f/4.9
• Pentax WG-2: 28-140mm equivalent, max aperture f/3.5 to f/5.5

The Nikon’s slightly wider angle allows more environmental context in tight spaces or wider landscapes. The wider max aperture at the short end also assists lower light and offers better background blur for portraits and macro.

Pentax provides more telephoto reach but narrower aperture, meaning you’ll need more light to handhold longer lenses steady without blur. However, WG-2 has a fabulous 1cm macro focus range, matching Nikon’s, which in practice produces stunning closeups with decent bokeh and detail.

Image stabilization differs too: AW120 has optical image stabilization, essential for telephoto and low light shooting, whereas WG-2 lacks in-camera stabilization, relying on lens and sensor design for steady shots.

Durability and Environmental Sealing: How Tough Are They Really?

Both cameras promise impressive ruggedness, but with some distinctions worth considering:

Both models survive dust, mud, drops, and extreme temps - basically a rugged photographer’s dream. The WG-2 adds crushproof sealing, making it slightly more durable under pressure or accidental sit-downs with a heavy pack. The AW120 extends waterproofing to 18 meters - four meters deeper than the WG-2 - an excellent bonus for serious snorkelers or casual divers.

Both cameras have built-in flashes with similar ranges (~5.2m), but WG-2 offers more variety in flash modes including soft and red-eye correction - useful for tricky lighting scenarios.

Video Capabilities: Beyond Still Life

While not the primary focus of rugged compacts, video recording is often a valuable built-in feature nowadays.

• Nikon AW120 records Full HD 1080p at 30fps, using efficient MPEG-4 and H.264 encoding.

• It offers basic in-camera stabilization and quick startup, great for capturing action sports or travel snippets.

• No microphone or headphone ports, so expect basic sound quality.

• Pentax WG-2 also shoots 1080p at 30fps, but interestingly supports multiple lower resolutions including 720p 60fps - allowing smoother motion capture for things like diving or biking.

• WG-2 supports timelapse recording, a nice creative bonus.

• Like Nikon, no external audio connections are available.

Overall video quality favors Nikon slightly for sharper imagery and reliable stabilization, but Pentax’s versatility in frame rates is appealing for videographers on the go.

Battery Life and Storage: Practical Considerations

Plenty of cameras overpromise battery life. Here, real-life endurance varies.

The AW120’s slightly better battery life means an extra half day shooting in the field before swapping batteries. Pentax’s internal storage provides insurance if your card fills or malfunctions, though the capacity is modest and should be viewed as a last resort.

Both cameras use the ubiquitous SD card format, making media swaps simple wherever you go.

Connectivity and Additional Features: Staying Linked

WiFi is a standard expectation at this price point:

• Nikon AW120 offers built-in WiFi and GPS, allowing direct image sharing and geotagging - crucial for travel photographers documenting locations on the fly.
• Pentax WG-2 lacks GPS but provides Eye-Fi compatibility (wireless SD cards), which is less convenient and slower than direct WiFi.

No NFC or Bluetooth in either camera, but HDMI output present for easy external viewing.
