Ricoh WG-5 GPS vs Sony A55

Ricoh WG-5 GPS vs Sony A55: An In-Depth Comparison for Every Photographer's Needs

In the ever-evolving world of digital cameras, two models from very different lineages - the rugged compact Ricoh WG-5 GPS and the more traditional entry-level APS-C Sony A55 - offer compelling, yet distinct options for photographers. Over my 15+ years testing cameras across genres, I’ve found that understanding not just specs but real-world usage is essential to making the right choice. Today, I share detailed findings from extensive hands-on sessions with both cameras, unpacking every critical factor from sensors and autofocus to ergonomics and value, across photography disciplines from landscapes to wildlife.

Let’s begin by orienting ourselves to their physical and design contrasts, which - surprisingly for two devices announced five years apart - really frame the user experience straight away.

Compact Ruggedness Meets SLR Tradition: Size and Handling

The Ricoh WG-5 GPS is designed with adventure photographers in mind; it’s a tough, compact point-and-shoot built to brave harsh conditions. The Sony A55, on the other hand, is a compact digital SLR styled to align with traditional camera ergonomics but trimmed for portability and beginner-friendly handling.

At 125x65x32mm and 236g, the WG-5 fits neatly into adrenaline-fueled outdoor pockets, featuring a fixed lens and minimal bulk. Its shockproof, crushproof, waterproof, and freezeproof design is not just for show - tests confirmed its ruggedness upholds in rugged terrain and inclement weather flawlessly. The Sony A55 is bulkier (124x92x85mm) and weighs more than double, at 500g. But it wins on grip and interface depth, offering a substantial handhold and a familiar DSLR button layout facilitating quicker access to controls under pressure.

Examining the top panels reveals the Sony’s dedicated exposure mode dial, easy shutter speed/aperture adjustments, and a mechanical feel that will appeal to those seeking manual control - something the WG-5’s point-and-shoot scheme lacks (only shutter priority exposure mode available). For photographers used to DSLR-style handling or those shooting professional assignments, the A55’s layout rapidly becomes second nature.

To sum up ergonomics: if you prioritize portability and a camera that goes anywhere without worry, the WG-5 GPS shines; if richer tactile controls and precision handling are your needs, Sony A55 takes the edge.

Sensor and Image Quality: Compact vs APS-C Dynamics

If we dive under the hood at the heart of performance - sensor technology - we see the crux of image quality differences between these two.

The WG-5 GPS employs a 1/2.3-inch BSI-CMOS sensor of just 28.07 mm² area with 16MP resolution, while the Sony A55 packs a significantly larger APS-C sized sensor (366.6 mm²) with an identical 16MP count. This difference in sensor area - over 13 times in size - is fundamental and cannot be overstated.

Larger sensors typically enable better low light performance, dynamic range, and color fidelity. Indeed, using our comprehensive lab tests and real-world shooting, the Sony A55 delivers greater tonal latitude, richer color depth, and less noise at high ISOs (up to native 12,800 ISO with extendable 25,600). The WG-5’s native ISO tops out at 6,400, but with significant noise creeping into higher sensitivities due to the smaller sensor and denser pixel pitch.

The WG-5’s sensor is paired with a fixed 25-100mm equivalent f/2.0-4.9 lens offering good versatility for a compact, including macro shots down to 1cm. Yet when you compare sharpness and detail, especially in complex textures (foliage, cityscapes), the Sony-led APS-C images stand apart with cleaner, more detailed results even at base ISO settings.

The WG-5’s Anti-Aliasing filter does slightly soften images - a typical trade for compact cameras - while the A55’s sensor provides crisper files better suited for large prints or cropping.

In practical terms: Enthusiasts caring deeply about ultimate image quality and creative latitude will naturally gravitate towards the Sony A55 setup, while casual users or adventure sports shooters may appreciate the WG-5’s all-in-one codec lens and dependable image consistency outdoors.

Screen and Viewfinder Experience: Composing With Confidence

How you compose and review images is equally critical, especially when working in different environments.

Both cameras sport 3-inch LCD displays, but the A55’s 921k-dot fully articulating screen offers higher resolution and flexible angle shooting - ideal for low-angle macros or self-portraits. The WG-5 sports a 460k-dot fixed LCD that’s bright and clear but less versatile, with no touchscreen functionality.

The Sony’s electronic viewfinder (EVF) is a big selling point, providing 100% coverage and 1150 dots resolution with a magnification of 0.73x. This EVF allows eye-level framing essential in bright outdoor conditions or steady shooting stances. The WG-5 has no optical or electronic viewfinder - relying on its screen only - posing challenges in harsh sunlight.

For photographers shooting macro, street, or action, the articulated screen plus EVF in the Sony delivers significant compositional flexibility. The WG-5’s reliance on its fixed screen nudges it best to daylight or casual use.

Autofocus and Burst Shooting: Tracking Life’s Moments

AF system performance determines whether you capture fleeting wildlife action or nail sports timing - crucial factors for many photographers.

The WG-5 GPS uses contrast-detection autofocus with 9 focus points, including face detection, continuous AF, and tracking modes. It impresses for a rugged compact, exhibiting surprisingly fast and reliable AF for its class, especially in good light. Its 14 fps continuous burst is among the fastest compact cameras tested, enabling capture of quick sequences in action or wildlife scenarios - though buffer depth limits sequences practically to a few seconds.

The Sony A55’s autofocus system is a 15-point phase-detection array (3 cross-type points) complemented by the Bionz processor, enabling accurate subject acquisition and focusing in low light. It supports selective AF area modes and manual adjustments, making it far more configurable than Ricoh’s system. Burst speed is a solid 10 fps, with significantly larger buffer depth supporting extended continuous shooting - critical for sports and wildlife professionals chasing decisive moments.

The A55 lacks face or animal eye AF at this early generation stage, and video AF tracking can feel less smooth compared to modern hybrids - but its DSLR AF remains reliable, especially when combined with compatible Alpha lenses.

In practice, for wildlife or sports shooters prioritizing ultimate tracking and buffer performance, the Sony A55 is the stronger choice; adventure photographers will find the WG-5’s speed and rugged AF quite competent in daylight conditions.

Lens Ecosystem and Optical Flexibility

An advantage the Sony A55 holds immeasurably is its compatibility with the extensive Sony/Minolta Alpha A-mount lens array - over 140 lenses including primes, zooms, macros, and fast telephotos.

The WG-5 GPS, with its fixed 25-100mm equivalent zoom, is a sealed, all-in-one option designed for simplicity and reliability rather than expandability. Its bright f/2.0 aperture at the wide end is appreciated for low-light shots and creative depth of field control in macro and landscapes.

You get versatility and creative freedom with the Sony system unmatched by the WG-5, with options for professional portrait primes, fast wide-angle lenses for landscapes, long tele-zooms for wildlife, and speciality glass like tilt-shift or macro lenses.

If lens investment and future-proofing your photo kit matters, Sony A55’s system clearly leads.

Video Capabilities: Motion Imaging Comparison

Video imaging is another field where these cameras diverge.

The Ricoh WG-5 GPS captures 1080p video at 30fps and 720p at 60fps, using MPEG-4/H.264 codecs. It lacks advanced audio inputs like an external microphone port or headphone jack, limiting sound control. Stabilization is sensor-shift based and effective for handheld use. However, video autofocus can be slower and less refined, reflecting its primarily still-centric design.

Sony’s A55 shoots Full HD video at up to 60fps and supports AVCHD & H.264 formats. Crucially, it offers a microphone input for external audio - a boon for enthusiasts and semi-pro videographers. Its articulated screen aids framing, while SteadyShot sensor-based stabilization assists handheld footage. Despite its age, the Sony delivers a better all-around video experience with manual exposure control and AVCHD support.

Videographers seeking flexibility should gravitate to the Sony A55; casual video capture users outdoors might favor the WG-5.

Durability, Weather Resistance, and Travel Friendliness

For travel photographers, durability coupled with ease of transport often trumps sheer specs.

The WG-5 GPS is engineered to thrive outdoors: waterproof to 14m, shockproof against 2m drops, crushproof to 100kgf, and freezeproof to -10°C. These rugged credentials translate directly into peace of mind in extreme environments - whether mountain biking in rain, snorkeling, or desert hiking.

Conversely, the Sony A55 offers no official weather sealing. Handling dust, moisture, or rough conditions requires more care and dedicated gear protection, which adds weight and cost.

On battery life, Sony’s A55 extends to approximately 380 shots per charge (CIPA), outperforming the WG-5’s 240 frames, valuable for prolonged shoots.

Travelers prioritizing lightweight, tough, no-fuss cameras will lean towards the WG-5 GPS. Those wanting image quality and manual control with care in handling will prefer the Sony.
