Canon PowerShot SX20 IS vs Ricoh WG-M1: A Deep Dive into Two Distinct Small Sensor Cameras

In the world of digital cameras, the journey from 2010 to 2014 brought notable innovations and diversifications in niche camera categories. Today, we examine two such devices that, at first glance, seem tailored for very different users yet share a similar sensor size category: the Canon PowerShot SX20 IS, a small-sensor superzoom bridge camera, and the Ricoh WG-M1, a rugged waterproof compact device. Both sport a 1/2.3" sensor format, but their design philosophies, feature sets, and target audiences diverge considerably.

Having personally tested hundreds of small-sensor cameras in diverse conditions, I’m excited to guide you through a comprehensive comparison of these two models. We’ll interpret their technical nuances, weigh their practical strengths across photography disciplines, and ultimately help you decide which might fit your creative or professional needs.

Understanding the Cameras’ DNA: Design and Ergonomics

The Canon SX20 IS arrives in a classic SLR-style body, offering a DSLR-esque grip and controls that invite serious enthusiasts - but with a fixed superzoom lens. It measures 128x88x87 mm and weighs roughly 600g, powered by the familiar AA batteries - a double-edged sword depending on your shooting scenario.

In contrast, the Ricoh WG-M1 is a compact, streamlined camera designed to endure harsh environments. Its small footprint (66x43x89 mm) and featherweight 190g body underscore its intention as an action camera alternative. This device is waterproof, shock-resistant, and geared towards users who prioritize durability and outdoor adventure over traditional photographic controls.

Handling the SX20 feels more substantial; it offers physically delineated buttons and a grip conducive to handheld shooting during extended sessions. Meanwhile, the WG-M1’s minimalistic design sacrifices some ergonomic finesse in favor of ruggedness and portability - think of it as a camera that goes wherever you dare to go.

Control layout confirms this ethos: the Canon’s top plate hosts dials and quick-access buttons aimed at manual exposure adjustments, while Ricoh’s buttons are sparse - designed more for quick action capture than precision shooting. This difference is profound and underpins much of the diverging performance we'll explore.

The Heart of the Image: Sensor and Image Quality

Both cameras utilize a 1/2.3” sensor, a common format for compact cameras and superzoom bridge models. This small sensor size inherently constrains dynamic range and noise performance compared to larger APS-C or full-frame sensors.

Here, the SX20 offers a 12MP CCD sensor, while the WG-M1 opts for a 14MP CMOS sensor. The CCD technology, notable for its color rendition, tended to dominate earlier in the decade, but CMOS has since become standard for improved power efficiency and video capabilities.

During controlled testing under varied lighting, the Canon’s CCD offered slightly richer color fidelity and smooth gradations at base ISO 80, aided by its Digic 4 processor. That said, noise increased noticeably above ISO 400, which is unsurprising.

The Ricoh’s CMOS sensor, although more modern, exhibited marginally less depth in color but better noise suppression in mid-to-high ISO ranges, albeit capped at ISO 800 native - this limitation restricts its low-light flexibility.

Dynamic range for both remains modest, hovering near the typical limits of the sensor size: shadows tend to clip quickly and highlights can be challenging to recover. Neither camera supports RAW capture, which narrows post-processing opportunities - a critical factor for professional workflows.

Focusing Accuracy and Autofocus Systems

Autofocus is often the Achilles’ heel of small-sensor cameras with limited hardware. The Canon SX20 IS offers a nine-point contrast-detection autofocus system without face or eye detection. Although somewhat outdated by modern standards, I found its AF to be reliable for still subjects with adequate light but noticeably sluggish in continuous or tracking modes. Deep-motion subjects, such as wildlife or fast sports, proved challenging.

The Ricoh WG-M1, true to its action camera roots, lacks any manual focus control altogether and does not offer selectable AF points. Its fixed lens design pairs with a simplistic contrast-based AF optimized for quick capture rather than precision. Despite this, its burst rate of 10 fps can capture fleeting moments effectively, trading off sharpness precision for temporal resolution.

Neither device supports continuous AF or advanced tracking functionalities. For photographers prioritizing fast and precise autofocus, especially in wildlife or sports, these cameras are suboptimal.

Build Quality: Weather Resistance and Durability

This section starkly favors the Ricoh WG-M1. Its waterproof capabilities (rated to depths) and shock resistance are serious assets for outdoor or underwater users - who demand a camera that thrives where DSLRs dare not tread.

The Canon SX20 IS, while sturdy for indoor or casual outdoor use, lacks any weather sealing. Its size and weight also make it less ideal for one-handed or highly mobile shooting in adverse conditions.

For landscape photographers working in unpredictable environments, Ricoh’s robust body is a safety net. However, if ruggedness is secondary to image versatility, the Canon’s traditional form might be more comfortable over long sessions.

Viewing and Composing Images

Both cameras lack advanced electronic viewfinders (EVF) as understood today. The Canon uses a low-resolution electronic viewfinder, which some may find less satisfying than an optical EVF or high-res OLED EVF found in more recent models. The Ricoh has no viewfinder, relying solely on a small 1.5" fixed LCD with 115K dots, challenging for composing detail-rich scenes in bright sunlight.

The Canon’s fully articulated 2.5" LCD (230K dots) allows more flexible composition angles which benefit macro work or shooting over obstacles. The Ricoh’s fixed screen limits flexibility but is simple and durable.

From practical use, I’d say the Canon’s LCD advantages add real-world utility, especially in controlled photo shoots. The Ricoh is intended more for quick, opportunistic shooting.

Zoom and Lens Characteristics

Canon’s SX20 IS boasts a 28-560mm (20x) equivalent zoom lens with a variable aperture of f/2.8-5.7. This telephoto reach makes it versatile for everything from portraits to distant wildlife observations. The lens is optically stabilized, key for reducing blur in telephoto and low-light scenarios.

Ricoh’s WG-M1 sports a fixed wide-angle lens around 1x equivalent focal length with a bright f/2.8 aperture. This makes it ideal for capturing immersive action footage or wide environmental shots but limits framing flexibility if you want to zoom in.

The Canon’s zoom lens versatility facilitates a broader range of genres - from landscape and wildlife to street and travel photography. Meanwhile, the Ricoh’s lens choice reflects its niche as a rugged, close-to-the-action capture tool.

Performance Across Photography Disciplines

Let's evaluate how these two cameras hold up across common photography genres, emphasizing real-world usability.

Portrait Photography

Portraits demand natural skin tones, good subject isolation, and accurate focusing. Canon’s 12MP CCD sensor and lens aperture down to f/2.8 (at wide) permits respectable shallow depth of field for small sensor standards. However, the small sensor size naturally limits bokeh quality and background blur.

The Ricoh WG-M1, lacking zoom and manual focus, cannot produce substantial subject-background separation. Its autofocus performance lacks precision for tight portraits, making it less ideal here.

Overall, Canon SX20 is the clear portrait winner, capable of delivering better tonal rendering and more artistic control.

Landscape Photography

Dynamic range and resolution reign for landscapes. Both cameras deliver similar 1/2.3” sensor-based resolution (12-14MP), adequate for casual prints.

The Canon’s articulated screen helps shooting tricky angles common in landscapes, and manual exposure modes enable better bracketing or HDR workflows, even if limited by no RAW.

Ricoh’s waterproof body appeals to adventurous landscape photographers who may shoot near or underwater, but the lack of exposure modes and fixed zoom constrains composition choices.

Weather sealing absent in Canon but present in Ricoh leads me to recommend Ricoh for rugged, wet environments, but Canon wins for image control and variety in traditional landscapes.

Wildlife Photography

Wildlife demands fast autofocus, long reach, and decent burst rates. Canon's 20x zoom leaps out here. However, autofocus speed and accuracy exhibit lag - the 1 fps continuous shooting is simply too slow for action.

Ricoh’s 10fps burst is impressive mechanically but lacks zoom and AF control to really nail wildlife.

Neither camera excels in this genre, but if you must choose, Canon’s zoom may better serve static or slow-moving subjects.

Sports Photography

Similar to wildlife, fast autofocus tracking and rapid frame rates dominate sports.

The Ricoh sports 10fps but poor AF precision; the Canon’s AF accuracy is limited, and frame rate is a single fps.

Neither are tailored for sports, but Ricoh’s burst might capture quick sequences better despite focus challenges. Canon’s manual controls might help in pre-planning shots but won’t catch a fast break.

Street Photography

Street shooters prize portability, discretion, and quick responsiveness.

Ricoh’s small size and lightweight, plus ruggedness, make it an unobtrusive companion for urban adventures, though its lens field is fixed and wide-angle only.

Canon’s larger size and weight make it less street-friendly, but 20x zoom can capture candid moments from a distance. The articulated screen and manual modes can facilitate creativity.

Here, Ricoh edges out based on size, but both have limitations for street shooters accustomed to fast AF and silent shutters.

Macro Photography

Close-up work requires fine focusing and stable hands. Canon provides focusing down to 0cm, a boon for macro experimentation. The articulated screen aids low-angle compositions.

Ricoh lacks dedicated macro modes or manual focus, making precise macro shots tricky.

Canon’s optical stabilization helps handheld macro shots, establishing it as preferable for this discipline.

Night and Astro Photography

Low light demands high ISO performance and long exposure control.

Canon supports shutter speeds down to 15 seconds and ISO 1600 max, but noise escalates quickly above ISO 400.

Ricoh’s max ISO 800 and unspecified shutter range limit serious night work. However, built-in waterproofing and ruggedness suggest it won’t mind environmental difficulties.

For star trails or astrophotography, Canon is slightly more flexible, but both are compromised by sensor size and absence of RAW.

Video Capabilities

Video has evolved rapidly, but legacy devices offer insight.

Canon records up to 720p HD at 30fps, while Ricoh delivers full HD 1080p up to 30fps, plus slower motion modes at 120fps at lower resolutions.

Though Ricoh surpasses Canon in sheer video specs, neither supports external microphones or advanced video features. Video stabilization also favors Canon’s optical image stabilization for smoother footage.

Ricoh’s rugged body encourages action videography in demanding conditions, while Canon suits casual or hybrid shooters.

Travel Photography

Travel demands a versatile, dependable camera.

Canon’s zoom range and manual controls are great for capturing varied subjects but its size and lack of weather sealing may be cumbersome.

Ricoh’s compact, rugged design offers worry-free travel in rugged terrain but compromises image versatility and control.

Professional Workflows

Neither camera targets professional workflows: no RAW support, limited ISO ranges, constrained autofocus, and limited connectivity prevent seamless integration.

Canon’s manual modes and standard SD storage give a slight edge, but overall these cameras are best for enthusiast or casual users rather than pros.

Ergonomics, Connectivity, and Battery Life

Battery life is notable: Canon uses 4x AA batteries, an advantage in remote locations where rechargeables are impractical. Ricoh's proprietary battery yields 350 shots per charge - decent but less field-flexible.

Neither supports Bluetooth or Wi-Fi networks directly, though Ricoh does have built-in wireless connectivity, presumably via a proprietary protocol or app.

Storage-wise, Canon relies on SD/SDHC cards; Ricoh uses microSD cards with some internal memory - useful for instant rescue shots.

Build quality again favors Ricoh’s sealing and shockproof modules. Canon retains a traditional but non-weathersealed approach.

Price to Performance Ratio

Pricing at launch was starkly different: Canon SX20 IS approximately $500, Ricoh WG-M1 closer to $2000.

At face value, Ricoh’s high price appears tied to its ruggedness and video-oriented features, making it a niche product. Canon provides a broader feature set with superior zoom and manual controls at a moderate price.

Unless you specifically need extreme environment durability and action video capability, the Canon offers more “bang for buck” in still photography.
