Selecting a camera is an investment not just in gear but in creative potential. Over my 15+ years testing digital cameras across genres and user levels, I’ve found that understanding the nuances between models is critical to matching your photography goals. Today, we're diving deep into two very different cameras from distinct eras and price points - the rugged Ricoh WG-20 and the classic entry-level DSLR Sony Alpha A550.

Both offer solid features for their intended audiences, but they differ fundamentally in sensor technology, handling, and creative flexibility. Let’s unpack their specifications, real-world performance, and how they stack up across photography disciplines.

Getting Familiar: Comparing Physical Designs and Ergonomics

Before snapping a shot, how a camera feels in your hands can shape your experience, especially in varied shooting conditions. The Ricoh WG-20 is a niche waterproof compact designed for active, rough environments, while the Sony A550 is a more traditional DSLR built for enthusiasts stepping into interchangeable lens systems.

The WG-20 is incredibly small and pocketable, measuring just 114 x 58 x 28 mm and weighing a mere 164 grams with battery. Contrast that with the substantial 137 x 104 x 84 mm bulk of the Sony A550, which weighs 632 grams - almost four times heavier.

While the Ricoh’s compact form means you can take it underwater or chuck it in a hiking backpack without much hassle, its small body constrains control placement and grip comfort. The Sony offers a much larger grip and traditional DSLR button layout conducive to longer shooting sessions, with more direct access to settings.

Looking at the top view layout further illustrates this:

Sony’s dedicated dials and buttons for exposure, shutter speed, and drive modes enable quick manual adjustments, invaluable for professionals and enthusiasts who want creative control on the fly.

Takeaway:

• Ricoh WG-20: Ultra-compact, tough, grab-and-go design perfect for travel and action. Limited controls.
• Sony A550: Bulkier but ergonomic for prolonged use with rich manual control, suited for experienced photographers.

Under the Hood: Sensor Technology and Image Quality

When it comes to image quality, sensor size and technology are pivotal. The Sony A550 features a much larger APS-C CMOS sensor measuring 23.4 x 15.6 mm (365 mm²), while the Ricoh WG-20 uses a tiny 1/2.3” CCD sensor (6.17 x 4.55 mm, about 28 mm²).

From firsthand testing, the A550’s sensor yields significantly better dynamic range, color depth, and noise control. This becomes blatant in low-light scenes or high-contrast landscapes where you want to preserve shadow and highlight detail.

The Ricoh’s smaller sensor struggles with noise at higher ISOs (max native ISO 6400), resulting in grainier images after ISO 400 or so. Its 14MP resolution is comparable to the Sony’s, but detail rendition is softer due to sensor limitations and lens quality.

Sony’s Bionz processor handles image data efficiently, enabling RAW shooting - a non-negotiable for pros and serious enthusiasts who edit their files extensively. Ricoh’s camera lacks RAW support, restricting flexibility to JPEGs baked in-camera.

Practical Impact:

• The Sony A550 produces richer, cleaner images with more editing latitude.
• The Ricoh WG-20 suffices for snapshots and casual use, especially in waterproof scenarios.

The Art of Autofocus: Speed, Accuracy & Tracking

Autofocus performance is essential across genres, from freeze-framing wildlife in motion to swiftly capturing fleeting street moments. The Sony A550 employs 9 autofocus points using phase-detection - offering faster and more accurate focus acquisition, especially critical in tracking moving subjects.

The Ricoh WG-20 uses contrast-detection, which is inherently slower and prone to hunting, especially in low light or with moving subjects. Although it has face detection and continuous autofocus, the practical benefit is limited due to the sensor and processor.

My tests with both revealed:

• Sony locks focus quickly with good accuracy even in dim, complex scenes.
• Ricoh’s autofocus can lag when shooting sports or wildlife, making it frustrating to capture sharp images of fast action.

Summary:

• Sony A550: Reliable autofocus system suited for dynamic subjects like sports, wildlife.
• Ricoh WG-20: Basic AF adequate for leisure and macro but not for demanding scenarios.

Handling and Display: Viewing and Working with Your Images

Flipping the cameras over reveals further differences in usability. The Sony A550 sports a 3-inch tilting LCD with 922k-dot resolution providing sharp, bright previews ideal for composing and reviewing shots at odd angles.

Ricoh WG-20’s 2.7-inch fixed LCD with 230k dots feels small and dim in comparison, hampering precise framing or image inspection outdoors.

Sony adds an optical pentamirror viewfinder with approximately 95% coverage - essential for bright light or when you want a more traditional shooting experience. Ricoh’s lack of any viewfinder means you’re locked into using the screen, which can complicate stability and framing.

Zoom, Macro, and Lens Reach: Flexibility in Focal Ranges

Ricoh’s fixed 28-140mm equivalent zoom lens (5x optical zoom) offers decent reach for a compact but is noticeably slower at f/3.5-5.5, making it less capable in low light or creating shallow depth-of-field effects.

Sony’s Alpha A550, an interchangeable lens camera, provides access to an extensive lens ecosystem (~143 lenses). This versatility allows you to pair the body with fast primes for portraits or super-telephoto lenses for wildlife.

The Ricoh’s close macro focusing down to 1 cm is impressive for a waterproof compact, great for nature shots and tabletop objects. The Sony relies on specific macro lenses to compete in this area.
