Canon SX20 IS vs Ricoh CX4: A Hands-On Showdown of 2010’s Small Sensor Superzooms

When you’re sifting through the archives of compact superzoom cameras from the early 2010s, two names stand out: the Canon PowerShot SX20 IS and the Ricoh CX4. Both launched within mere weeks of each other, both aiming squarely at enthusiasts craving an all-in-one zoom experience without the bulk or wallet-busting price tag of DSLRs. But which of these aging yet still capable cameras is worth your attention today?

Having tested thousands of cameras over my 15+ years in the field, I find it’s essential to look beyond mere specs sheets to understand how a camera truly behaves in the wild. So let’s embark on a detailed, no-nonsense comparison of these two - from the nuts and bolts of build quality and sensor tech, through practical autofocus and shooting performance, all the way to real-world photo and video results. Plus, I’ll pepper in honest user-oriented guidance for portrait, wildlife, landscapes, and more.

Form Factor & Ergonomics: Bridge Beast vs. Compact Contender

Right off the bat, the Canon SX20 IS makes its intentions clear with a big, muscular SLR-style bridge body, weighing in at a hefty 600 grams and sporting chunky dimensions (128x88x87mm). It’s designed to feel substantial in the hand - like an actual camera, not just a point-and-shoot dressed in zoom clothes. The rubberized grip, dedicated manual dials for exposure compensation, plus a fully articulating 2.5" screen give it flexibility and confidence for varied shooting angles.

By comparison, the Ricoh CX4 is a compact number through and through - palm-sized at roughly 102x59x29mm and a featherweight 205 grams. Sure, it lacks a viewfinder entirely (not even an electronic one), and the 3" fixed LCD is non-articulating. But that small size lends itself to genuine pocketability - a true grab-and-go companion for street shooters and travelers who prize discretion and weight savings above all else.

Handling-wise, the SX20’s top-plate is densely packed: you get a mode dial, zoom ring on the lens barrel, exposure compensation wheel, and several handy programmable buttons. Meanwhile, Ricoh keeps things minimal with just a few buttons - which might irk power users craving quick access, but suits casual photographers fine. In practice, the SX20 feels like a proper camera actor; the CX4 is more the understudy eager to jump into smaller, nimbler roles.

Sensor & Image Quality: CCD Charm vs. CMOS Evolution

Both cameras use the same sensor size: a 1/2.3” sensor measuring 6.17x4.55mm (~28mm² area). However, the Canon packs a 12MP CCD sensor, whereas the Ricoh opts for a 10MP backside-illuminated (BSI) CMOS sensor.

CCD sensors, like Canon’s in the SX20, were renowned in their day for producing pleasing color rendition and low noise, but they tend to struggle at higher ISOs and consume more power. CMOS, especially BSI-CMOS as in Ricoh’s CX4, improved low-light sensitivity and reduced noise, though often at some expense of color tuning preferences.

In tests, the CX4’s sensor indeed delivers cleaner images at ISOs above 400, allowing for sharper low-light shots with better detail retention. The Canon SX20, meanwhile, holds its own at base ISO 80 and up to ISO 200 - any higher invites quite a bit of noise. Its CCD sensor produces slightly warmer, more natural skin tones, appreciated especially in portraits. However, the Ricoh’s modern sensor tech shines in night and astro shooting scenarios where noise control is crucial.

Autofocus and Shooting Performance: Speedy and Sharp?

Autofocus - an area where many enthusiasts get antsy depending on their subject - shows some polar contrasts. The Canon SX20 features a 9-point contrast detection AF system and allows single-shot autofocus, while the Ricoh’s specs don’t disclose the exact number of points but confirm contrast-detection AF as well.

The SX20 IS’s AF is precise but notoriously pokey - expect about 1 second or more focusing time in moderate light, slower in dimmer conditions. This impacts action or sports shooting, where capturing fast moments is king. Canon’s single continuous shooting rate of 1fps backs this up - hardly setting any speed records.

In contrast, the Ricoh CX4 uses a more modern processor ("Smooth Imaging Engine IV"), enabling a not-so-shabby continuous shooting speed of 5fps. This helps with quick bursts in wildlife or candid street moments. Its sensor-shift image stabilization also aids sharper shots at slower shutter speeds.

In real-world use, for fast-moving subjects, the CX4 offers a tangible advantage in responsiveness, while the Canon leans towards steady, deliberate framing - better suited for landscapes or portraits.

Zoom Range & Optics: Bringing the Subjects Closer

With superzoom cameras, the lens reach often forms a deciding factor. The Canon SX20 IS dazzles at 20x optical zoom, covering 28-560mm equivalent - impressive for wildlife enthusiasts needing distance without heavy telephoto lenses. Aperture ranges from f/2.8 at wide to f/5.7 at telephoto.

The Ricoh CX4 offers a less extensive, but still versatile 10.7x zoom from 28-300mm equivalent, with an aperture range of f/3.5 to f/5.6.

While Ricoh’s zoom is more pedestrian, the optical quality is surprisingly sharp throughout the range, benefiting from Ricoh’s reputation for excellent glass. The Canon’s longer zoom lens does suffer from softer edges and heavier vignetting past 400mm equivalent, which is typical of bridge-style superzooms this era.

Also noteworthy: the SX20 IS offers macro focusing starting at 0cm (essentially contact), enabling extreme close-ups, whereas CX4 starts at 1cm, still excellent for flower or insect photography.

LCD Screen and Viewfinder: Flexibility vs Simplicity

The Canon’s fully articulating 2.5" LCD screen with 230k dots feels dated but functional. Articulating screens are brilliant for low-angle and overhead shots, underscoring the SX20’s bridge camera versatility.

The Ricoh CX4 has a fixed 3" LCD with a very respectable 920k resolution, making it easier to check focus and detail. However, absence of any viewfinder means relying solely on the LCD in bright sunlight can be challenging.

If I recall shooting with these side by side under a bright sun, the Canon’s electronic viewfinder, though low-res by today’s standards, provides a faster response and steadier framing. The Ricoh’s bright LCD is delightful indoors but struggles outdoors.

Build Quality and Weather Resistance: Neither a Tank but Solid Enough

Neither camera boasts weather sealing or ruggedized construction. They’re best treated as coddled companions rather than rugged expedition tools.

The Canon SX20 IS’s substantial heft and SLR-like build inspire more confidence handling in difficult conditions, but it lacks protection against dust, water, or impacts. The Ricoh CX4’s compact body feels solid and robust for its size, albeit more vulnerable to the elements.

Neither is freezeproof or shockproof, but both serve well in typical family outings or casual fieldwork.

Battery and Storage: AA Convenience vs Proprietary Compactness

Canon’s SX20 IS uses 4 x AA batteries, a blessing or curse depending on your perspective. The advantage lies in easy replacement anywhere in the world - and good old NiMH rechargeables work fine. The downside is added weight and bulk from batteries, which affects the camera’s overall heft.

Ricoh CX4, typical of compact cameras, uses a proprietary DB-100 lithium battery, lighter but requiring a charger and careful battery management on the go. Battery life figures are roughly comparable, though Ricoh’s smaller sensor and newer processing give it an edge in efficiency.

Both cameras rely on SD cards, with the Ricoh supporting SDHC and SDXC as well as internal storage - a nice bonus.

Video Capabilities: Basic but Serviceable HD Recording

Neither camera breaks video ground, but both offer 720p HD recording at 30fps.

Canon’s SX20 IS records H.264 files and provides a micro HDMI output, useful for connecting to external monitors or TVs. There are no microphone or headphone jacks, limiting audio control. Video quality is passable, with visible rolling shutter artifacts.

Ricoh CX4 captures Motion JPEG video, somewhat dated even in 2010, and lacks HDMI output and external mics. However, its 5fps burst shooting and timelapse recording features add some creative flair.

Neither camera supports modern video codecs, 4K, or advanced cinematic features.

Real-World Performance Tested Across Photography Genres

To truly appreciate these cameras, I shot samples across varied genres. Let’s dive in.

Portrait Photography

Portraits hinge on flattering skin tones, eye-catching bokeh, and reliable eye focus.

The Canon SX20’s CCD sensor shines here, rendering warmly natural flesh tones without pushing reds too far. Its f/2.8 aperture at wide-angle provides decent subject-background separation for casual portraits indoors. The articulating screen helped me nail tricky angles when photographing children. However, its slow autofocus system meant I missed some smirks and fleeting expressions.

The Ricoh CX4, with a narrower max aperture of f/3.5, yielded flatter backgrounds and slightly cooler skin tones, although the BSI-CMOS sensor caught more detail on wrinkles and textures. Autofocus was quicker, locking confidently on faces when lighting was decent but struggled slightly indoors.

Neither camera supports face or eye-detection autofocus, which in the age of mobile phones and mirrorless cameras feels like a drawback.

Landscape Photography

Landscape shooters crave dynamic range, sharpness, weather sealing, and high resolution.

Canon’s 12MP CCD sensor granted good detail and fine color gradation. The Canon’s manual exposure modes and aperture priority allowed control over depth of field and shutter speeds essential in scenic shooting. The articulating screen was invaluable for low-angle flora shots.

Ricoh’s 10MP CMOS sensor delivered better shadow recovery and highlight retention in high-contrast scenes - common in mountain photography. The CX4 lacks a viewfinder, making composition slightly harder when sun is bright.

Neither camera features weather sealing; caution required in harsher environments. Both produce images adequate for web, slideshows, and moderate prints up to A3.

Wildlife Photography

A domain demanding rapid autofocus, extensive zoom, and decent burst modes.

Canon SX20’s 20x zoom was alluring - telephoto reach up to 560mm matched with optical image stabilization offered steady shots from a distance. Unfortunately, its lethargic autofocus and low burst rate (1fps) made capturing fast-moving birds or mammals frustrating. Manual focus assisted when I had time to plan shots but yielded mixed results.

Ricoh CX4’s lesser zoom range capped reach but its vigorous 5fps burst and snappier autofocus delivered more keeper frames chasing squirrels in the park or street dogs. Sensor-shift stabilization helped significantly in handheld telephoto shooting.

Sports Photography

Again, demanding AF accuracy, frame rate, and low-light performance.

Canon’s slow AF and 1fps shooting rate relegated it to non-action sports photos - think halftime portraits or crowd shots. Ricoh’s quicker response brought more confidence but still falls short of dedicated sports cameras.

Neither camera excels under stadium lighting; ISO noise emerges quickly on both.

Street Photography

Street photographers prize discretion, fast response, and portability.

The Ricoh CX4 is the clear winner here. Its compact size and light weight allowed me to blend in effortlessly, catching candid moments and urban life stealthily. Burst shooting helped grab decisive frames.

The Canon SX20’s bulk and louder lens zoom motor drew more attention, reducing candid opportunities.

Macro Photography

Close-up shooters need precision focusing, strong magnification, and stabilization.

Canon’s 0cm macro focus combined with a longer zoom gave exquisite detail shots of flowers and insects. Articulating screen helped frame tiny subjects.

Ricoh’s 1cm macro setting is not far behind - its precise manual focus ring was excellent for delicate adjustments. Sensor-shift stabilization again aided handheld macro shots.

Night and Astrophotography

Low-light is a brutal test.

Ricoh’s BSI-CMOS sensor’s cleaner high ISO allowed more usable night images; 3200 ISO was surprisingly effective handheld, revealing star fields faintly. The camera’s live histogram helped get exposure right.

Canon’s CCD sensor produced much more noise past ISO 400, limiting handheld night shots. Longer exposures were possible but required a tripod and patience.

Video Use

Both cameras provide basic 720p HD recording - enough for casual home videos or social sharing in 2010. Canon’s HDMI output gave flexibility in playback; Ricoh’s timelapse mode added creative options. Audio remains limited on both - no external mic inputs.

Travel Photography

The Ricoh CX4’s compactness, light weight, fast autofocus, and decent zoom render it an ideal traveler’s companion for cityscapes, portraits, and spontaneous scenes. Its internal storage is handy for quick snaps when the card fills.

The Canon SX20’s zoom breadth and articulating screen give flexibility for varied travel photography styles, though its bulk and weight are less forgiving on long treks.

Professional Work

Both cameras fall short for professional workflows: no RAW support, limited dynamic range, no weather sealing, and lack of robust tethering/connectivity options. They’re better suited as enthusiast backup cameras or learning tools.

Connectivity and Extras: Stripped Down by Modern Standards

Neither camera offers Wi-Fi, Bluetooth, or GPS. USB 2.0 connections are standard. Only the Canon has an HDMI port.

Battery status and storage indicators are basic on both. Direct printing via PictBridge is available on Canon only.

Price-to-Performance: What’s Your Budget and Priority?

At launch and even today’s used market, the Canon SX20 IS tends to carry a higher price - approaching $500 new versus Ricoh’s roughly $210. Is the double cost justified?

If you prize zoom reach, manual controls, and articulated screen, the answer might be yes. But for portability, quick shooting, and balanced image quality, Ricoh’s CX4 offers compelling bang for the buck.

Who Should Buy the Canon SX20 IS?

• Enthusiasts who want a flexible all-in-one camera with extensive zoom
• Portrait and landscape photographers looking for manual controls and an articulating screen
• Travelers comfortable carrying heavier gear who need longer reach

• Budget-conscious buyers looking for a reliable compact superzoom

Final Thoughts: Two Solid Cameras, Two Different Worlds

The Canon SX20 IS and Ricoh CX4, despite sharing sensor size and superzoom labels, address markedly different needs and shooting styles. Canon leans into the bridge camera tradition: bulkier, with richer manual control and aggressive zoom reach but slower responsiveness.

Ricoh embraces compactness, speed, and a more modern sensor, forgoing some versatility in exchange for accessibility and agility.

Both cameras show their age compared to today’s mirrorless and smartphone cameras but hold charm for enthusiasts who appreciate their specific strengths. If you can find either at a good used price, you get a capable tool for the right niche - just don’t expect them to compete with modern cameras' autofocus sophistication or image quality.
