Casio EX-H20G vs. Ricoh WG-6: A Hands-On Comparison for the Practical Photographer

When selecting a compact camera, enthusiasts and professionals alike seek a device that balances performance, versatility, and reliability without unnecessary bulk or complexity. After personally testing a broad spectrum of cameras over the years - including thousands of compact models like these - I’m excited to share an in-depth comparison between two compelling entries: the Casio EX-H20G (2010) and the Ricoh WG-6 (2018). While both share a compact form factor and fixed lens design, their differing priorities - the EX-H20G as a travel-focused zoom compact and the WG-6 as a rugged waterproof option - provide distinct advantages and trade-offs.

Whether you’re deciding on your next travel companion, a versatile all-rounder, or a field-ready adventure camera, this detailed review draws on rigorous hands-on testing and real-world shooting to help you choose wisely. Let’s dive in.

A Tale of Two Compact Cameras: Understanding Their DNA

Before we dig into the nitty-gritty performance details, examining the physical design and ergonomics offers a foundation.

The Casio EX-H20G debuted in 2010 as a bridge between pocket-friendly and feature-rich compact cameras - featuring a powerful 10x optical zoom (24-240mm equivalent). By contrast, the Ricoh WG-6 is a rugged specialist released eight years later, with a 5x optical zoom (28-140mm equivalent), designed to survive harsh environments while delivering solid imaging performance.

Size and Handling: Which Fits Your Grip?

As illustrated above, the EX-H20G measures 103 x 68 x 29 mm and weighs a mere 216 grams, making it lighter and slightly smaller than the WG-6’s 118 x 66 x 33 mm body at 246 grams. The WG-6’s thicker, beefier build reflects its ruggedness, incorporating seals and protective materials.

In real use, the EX-H20G feels pleasantly pocketable and better suited for extended handheld shooting due to its lighter weight and more familiar slim profile. The WG-6, while heavier, offers reassuring grip security with rubberized surfaces – great for slick or cold conditions where handling can be tricky.

Ergonomics Tip: If you prioritize portability and travel convenience, the EX-H20G edges ahead. But for fieldwork, rugged adventures, or water sports, the WG-6’s design ensures peace of mind and durability.

Design and Controls: Everyday Usability Under the Microscope

Moving from size to interface, the top-panel control layout directly influences how swiftly and intuitively you can adjust settings.

The EX-H20G has a straightforward button array and mode dial, reflecting an older, more traditional camera interface. Its shutter, zoom rocker, and quick-access buttons respond reliably but lack the refinement of newer designs. The rear panel includes a 3-inch fixed LCD (no touchscreen), which sufficed for its time but is limited in resolution (461k dots).

The WG-6’s top layout is a bit more modern yet minimalist, focusing on ruggedness over flashy controls. It keeps simplicity at heart: reasonably large buttons spaced to prevent accidental presses while wearing gloves. The 3-inch rear LCD (1040k dots) is notably sharper, aiding in manual focusing accuracy and framing in bright outdoor conditions.

Interface Insight: The WG-6’s screen and controls reflect a thoughtful balance between durability and usability. The EX-H20G may feel dated now but still offers a familiar user experience for those used to early 2010s compacts.

Sensor & Image Quality: Old vs. New Generation Technology

Sensor technology forms the heart of image quality, and here, the cameras differ in fundamental ways:

• Casio EX-H20G: 1/2.3" CCD sensor, 14 MP resolution, ISO 64-3200, anti-aliasing filter enabled
• Ricoh WG-6: 1/2.3" BSI-CMOS sensor, 20 MP resolution, ISO 125-6400, also with anti-aliasing filter

While both cameras use the same physical sensor size (approx. 6.17 x 4.55 mm), the WG-6 benefits from newer backside-illuminated CMOS technology, which captures more light effectively than the older CCD sensor on the EX-H20G. This results in cleaner images, better dynamic range, and improved low-light performance.

Real-World Sensor Testing: Capturing an outdoor landscape at ISO 800 with the EX-H20G reveals more noise and less highlight retention when compared side-by-side with the WG-6 under the same conditions. The WG-6’s 20MP sensor also enables higher resolution images (5184x3888 pixels vs. 4320x3240 pixels on the EX-H20G), beneficial for large prints or extensive cropping.

Practical Tip: If you prioritize detailed, crisp images in diverse lighting, the WG-6’s sensor advances are substantial. The EX-H20G still produces acceptable images in good light but struggles as ISO climbs.

LCD Screen and User Interface

Back-screen usability is often overlooked but critical for framing and reviewing shots outdoors.

From my testing under direct sunlight, the WG-6’s 1040k-dot screen outperforms the EX-H20G’s 461k-dot display in clarity and brightness, making it far easier to check focus and composition on the spot. Neither camera features a viewfinder or touchscreen, which can slow operation for some users.

Although the WG-6’s screen is fixed, its higher resolution and brightness compensate, especially for on-the-go shooting in challenging conditions such as underwater or snowy environments.

User Experience Insight: For photographers who primarily compose on the rear screen in variable light, the WG-6 delivers a clearer, more confidence-inspiring interface.

Autofocus and Focusing Versatility

Autofocus speed and accuracy are vital for capturing sharp images, especially in dynamic situations.

• EX-H20G: Focus system based on contrast detection only, single AF mode, no face or animal eye detection, no continuous or tracking AF
• WG-6: Contrast-detection AF with face detection, 9 focus points, continuous AF, and AF tracking

In my field tests shooting moving subjects such as kids and pets, the WG-6’s autofocus system reliably locked on subjects and tracked motion better, reducing frustrating missed shots. The Casio’s AF struggled, exhibiting lag and hunting when lighting was less than ideal or subjects started to move unpredictably.

This limitation on the EX-H20G constrains its usefulness for wildlife, sports, or street photography where quick focusing and subject tracking matter.

Pro Tip: If your work involves any motion capture or interactive photography, the WG-6’s autofocus capabilities provide a meaningful advantage.

Lens and Optical Performance

Both cameras have fixed zoom lenses but differ in focal ranges and apertures:

• EX-H20G: 24-240mm equivalent (10x zoom), F3.2 - 5.7 aperture
• WG-6: 28-140mm equivalent (5x zoom), F3.5 - 5.5 aperture

The EX-H20G’s much longer zoom range is impressive, providing great versatility from wide-angle landscapes and group shots to distant wildlife or architectural details. However, increased zoom compromises aperture size and, ultimately, light gathering.

The WG-6’s shorter zoom is more modest but still provides ample framing options for travel, underwater, and macro photography.

Regarding macro capabilities, the WG-6’s ability to focus as close as 1cm versus the EX-H20G’s 7cm minimum brings it into serious consideration for macro lovers or detail-oriented shooters.

Lens Observation: If zoom reach is your priority, EX-H20G reigns supreme, but for close-up precision and flexibility, WG-6’s lens shines.

Image Stabilization - Keeping Shots Sharp

Image stabilization prevents blur during handheld shooting, especially at long zooms or slow shutter speeds.

• EX-H20G: Sensor-shift (optical) stabilization
• WG-6: Digital stabilization

While sensor-shift is generally preferable to digital stabilization due to less degradation in image quality, in this comparison, the WG-6’s digital approach is effective enough largely because its shorter zoom range demands less extreme stabilization.

In low-light situations, EX-H20G’s form of stabilization delivered sharper handheld shots but with caveats: slower autofocus and manual focus required some patience. WG-6’s stabilization aids video and high ISO shots, though slight softness could sometimes creep in with aggressive digital compensation.

Real-Use Note: For photographers regularly shooting zoomed or in dim conditions without a tripod, EX-H20G’s stabilization may prevent obvious blur better, but WG-6 remains practical for most casual to mid-level shooting scenarios.

Weather Sealing and Ruggedness: Built for Adventures?

This is an area that clearly differentiates these two cameras.

• EX-H20G: No weather sealing, nor any shockproofing, freezeproofing, or dustproofing
• WG-6: Fully waterproof (down to 15 meters), shockproof (2m drops), crushproof (100kgf), dustproof, and freezeproof (-10°C)

For an outdoors photographer (hiker, diver, climber), the WG-6 excels by design. I've personally taken it underwater and through rugged terrain without protective housing - results were consistently reliable with no failures or moisture ingress.

The EX-H20G, by contrast, is a more delicate tool. Keep it dry and clean, and it serves well - but plan carefully if conditions get rough or wet.

Battery Life and Storage

WG-6 includes a modest 340-shot battery rating, rechargeable lithium-ion battery pack, and internal storage plus SD card slot for convenient backup.

EX-H20G uses the NP-90 rechargeable battery with unspecified official battery life but generally less endurance given older power management.

In practice, the WG-6’s battery is more dependable for day-long shoots, and having internal storage adds convenience should you run short on SD card capacity.

For storage, both support SD, SDHC, and SDXC cards, but the WG-6 supports FlashAir wireless SD cards for limited wireless connectivity - a small bonus in the field.

Video Capabilities: Casual Clips or Serious Filmmaking?

• EX-H20G: 720p HD video @ 30fps, H.264
• WG-6: 4K UHD 3840 x 2160 video @ 30fps, MPEG-4 / H.264

Video performance clearly favors the WG-6 here, which offers 4K footage suitable even for casual vlogging or detailed video documentation. I tested the 4K mode outdoors, and while stabilization isn’t perfect, the image quality is respectable for a compact.

The Casio’s 720p video feels dated and restricts creative flexibility. No microphone or headphone ports on either camera limits audio quality and monitoring.

Video Suggestion: If video is part of your workflow, WG-6 dramatically outperforms the EX-H20G.

Genre-by-Genre Performance Overview

Let’s break down real-world suitability by photographic type, referencing my experience and measured outcomes:

• Portraits: WG-6’s face detection autofocus and higher resolution sensor offer better skin tone accuracy and sharper eye detail. EX-H20G’s long zoom helps with candid portraits from a distance but lacks AF sophistication.
• Landscape: Both cameras suffice, but WG-6’s wider dynamic range and weather sealing make it safer and more versatile outdoors.
• Wildlife: EX-H20G’s 10x zoom wins for framing distant subjects, but slow AF undermines catching action. WG-6’s 5x zoom limits reach, but faster AF partially offsets this.
• Sports: Neither camera is ideal, but WG-6’s continuous AF and faster shutter ceiling (1/4000s) edge ahead.
• Street: EX-H20G’s lighter size and zoom versatility weigh in but slow AF and no face detection are drawbacks compared to WG-6’s AF benefits.
• Macro: WG-6 excels with 1cm minimum focus and better stabilization.
• Night/Astro: WG-6’s higher max ISO and better sensor beat EX-H20G in low-light shooting.
• Video: WG-6 clearly better with 4K support.
• Travel: EX-H20G is pocketable; WG-6 offers robustness.
• Pro Work: Neither camera replaces professional DSLRs or mirrorless, but WG-6’s ruggedness and connectivity tools improve workflow reliability.
