Ricoh WG-30 vs Sony SLT-A57: A Comprehensive Camera Comparison for Every Photographer

Choosing a camera often hinges not just on specs, but on how the device performs in the hands of a photographer across real-world scenarios. Having tested thousands of cameras over the past 15 years - from rugged compacts to high-end DSLRs - I’m diving deep into two very different photographic tools: the Ricoh WG-30, a rugged waterproof compact, and the Sony SLT-A57, an entry-level DSLR-class hybrid from the earlier DSLM/SLT generation.

These cameras target distinct user needs and shooting styles, but both remain relevant players depending on your priorities. In this detailed comparison, I’ll cover their technical strengths, practical usability, and suitability across photography genres to help you decide which fits your creative ambitions - and budget.

Let’s start by examining their physical characteristics and design philosophies.

First Impressions: Size, Build Quality, and Ergonomics

Out of the gate, the difference is stark. The Ricoh WG-30 is a compact, heavily weatherproofed point-and-shoot designed for active, adventurous scenarios. At 123 x 62 x 30 mm and weighing just 192 grams, it’s highly portable and easy to stash in pockets or small bags. Its rubberized chassis allows you to shoot underwater, withstand shocks, and endure freezing temps. I tested this camera during a rainstorm and on rough terrain with zero worries about water or grit damage - ideal for rugged outdoor use.

By contrast, the Sony A57 measures a much bulkier 132 x 98 x 81 mm and weighs 618 grams. It has a sturdy but plastic-heavy DSLR-style body with no special environmental sealing. The grip is comfortable but the size makes it less pocketable - more of a dedicated photography tool. It’s built for manual control and extended shooting sessions, not casual or extreme environments.

This size and durability trade-off influences how you might use each camera daily.

Design and Control Layout: Intuitive Usability for Different Users

The Sony A57 features the classic DSLR layout: multiple dials for shutter speed, aperture, and exposure compensation, along with customizable buttons. Its fully articulated 3-inch screen (921k dots) is paired with a bright electronic viewfinder (EVF), useful for precise framing outdoors. The EVF’s 100% coverage and 0.7x magnification offer an experience close to an optical viewfinder, which I appreciated during bright daylight shooting.

The Ricoh WG-30’s controls are minimal by comparison - small buttons and modes focused on waterproof and shockproof reliability. Its 2.7-inch fixed LCD screen (230k dots) is readable but creaky in bright light. There’s no EVF or touchscreen.

For photographers who like direct manual exposure tweaking and rely on an EVF, the A57 is the clear winner. I found myself fumbling a little on the Ricoh during fast action shot settings, while the Sony felt familiar and tactile.

Sensor Technology & Image Quality: Size Matters

This comparison hinges fundamentally on sensor size and technology. The Ricoh has a small 1/2.3-inch CMOS sensor (6.17 x 4.55 mm) at 16 megapixels, common in compact cameras. This sensor size limits dynamic range, low-light performance, and depth-of-field control.

The Sony packs a much larger APS-C sized CMOS sensor (23.5 x 15.6 mm) also at 16MP but with significantly better photon-collecting ability. This sensor yields:

• Superior image quality with less noise at high ISO.
• Much greater dynamic range for shadows and highlights.
• Enhanced background blur capabilities.

DxOMark testing (available for Sony A57 but not Ricoh WG-30) reports color depth of 23.4 bits, dynamic range of 13 EV stops, and usable ISO up to 785 - a solid performance for an entry-level DSLR.

I conducted side-by-side shooting of landscape and portrait scenes in low light. The Sony files retained impressive detail and color fidelity at ISO 800, while the Ricoh images showed noticeable grain and reduced sharpness. For web use, Ricoh suffices, but for prints or professional work, the Sony’s sensor shines.

LCD & Viewfinder: Framing Your Shot

Aside from sensor differences, the Sony’s 3-inch articulating Xtra Fine TFT LCD with TruBlack technology delivers bright, crisp live view - essential for accurate focusing and composition, especially at awkward angles.

The Ricoh’s smaller, low-resolution fixed screen is serviceable but lacks fine detail, which I found a limitation when reviewing focus and exposure quickly during field testing.

No optical or electronic viewfinder on the Ricoh means reliance solely on the LCD, which can be problematic in bright daylight or fast-paced shooting.

For users who value precise framing and comfort during prolonged shoots, the Sony’s superior viewfinder and screen setup offer a better experience.

Autofocus Performance and Speed: Catching the Moment

The Sony is equipped with a hybrid autofocus system (phase detection + contrast detection) featuring 15 AF points, including 3 cross-type sensors. This system enables fast, accurate autofocus and effective subject tracking, a plus for wildlife, sports, and general action photography.

The Ricoh’s contrast-detection system is limited to 9 AF points without phase detection, meaning autofocus can be slower and less reliable in low contrast or fast-moving subjects.

In my hands-on testing, the Sony A57 easily tracked moving models with precision, especially in continuous autofocus mode at 12 fps burst rate, while the Ricoh stumbled during action sequences with a 1 fps continuous rate.

Lens Ecosystem: Fixed Convenience vs Interchangeable Flexibility

The Ricoh WG-30 sports a fixed 28-140mm equivalent zoom lens (5x optical zoom, f/3.5-5.5), designed to provide versatile framing in a waterproof package. The trade-off is limited optical flexibility but total portability and ruggedness.

Sony’s A57 accepts any lens with the Sony/Minolta Alpha mount, opening a massive realm of choice: standard primes, telephoto zooms, macros, and specialty optics. I tested the A57 with a Sony 70-300mm zoom and a 50mm f/1.8 prime, both delivering excellent sharpness and versatility unmatched by the Ricoh.

Photographers craving adaptability and growth in their kit will appreciate Sony’s broad lens range. Meanwhile, the Ricoh’s fixed lens and compact nature suit those valuing convenience and resilience over optical swappability.

Battery Life and Storage: Endurance in the Field

The Sony A57’s NP-FM500H battery offers approximately 550 shots per charge based on CIPA standards, which matches my field experiences. This supports extensive shooting sessions without frequent recharging.

Ricoh WG-30’s smaller battery claims around 300 shots, suitable given its compact design and simpler electronics, yet fewer frames on a charge.

Both cameras use a single SD card slot; the Sony also supports Memory Stick formats, offering extra flexibility.

If battery longevity matters on long trips or professional shoots, Sony provides a noticeable advantage.

Connectivity: Sharing and Workflow Integration

Connectivity is basic on both models. Ricoh WG-30 omits Wi-Fi or Bluetooth, limiting easy photo transfer. It does offer HDMI out for direct playback on TVs.

Sony A57 features Eye-Fi card support (wireless-enabled SD cards) to facilitate image transfers more conveniently, along with HDMI and USB 2.0. No native Wi-Fi or Bluetooth, reflecting its 2012 release date.

For photographers relying on wireless workflows, neither camera is ideal by modern standards, but Sony’s Eye-Fi compatibility provides a partial solution.

Video Capabilities: Basic Recording to Creative Potential

Both cameras record Full HD video, but the Sony offers superior frame rate options and formats:

• Sony records up to 1080p at 60fps in AVCHD or MPEG-4, enabling smoother motion capture.
• Ricoh records at 1080p 30fps with simple H.264 compression.

Sony also includes a microphone jack for improved audio capture, while Ricoh lacks any external audio input.

In practical terms, if video is part of your workflow, the Sony offers greater flexibility and quality.

Weather Sealing and Rugged Features: Ready for Rough Environments

The Ricoh WG-30 is dustproof, shockproof (2m drops), crushproof (100 kgf), freezeproof (-10°C), and waterproof (up to 10m), classifying it as an adventure-ready camera. I took it kayaking and hiking with no issues.

Sony A57 lacks environmental sealing, meaning cautious use in harsh conditions is required.

If you shoot outdoors under tough weather conditions, the Ricoh is the obvious choice.
