Casio EX-G1 vs Ricoh WG-4 GPS: A Hands-On Comparison for Photography Enthusiasts and Pros

Choosing the right compact camera can feel like navigating a jungle of tech specs, marketing buzzwords, and sometimes bewildering feature lists. Over my 15+ years testing everything from flagship DSLRs to rugged point-and-shoots, I've learned that strong specs on paper rarely tell the full story. The real magic is how a camera performs in your hands and on your chosen subjects. Today, I’m putting two intriguing compact models head-to-head - the Casio EX-G1 and the Ricoh WG-4 GPS - to help you cut through the noise and find the right fit for your photography journey.

Despite both cameras being from relatively specialized categories - the EX-G1 is an ultracompact waterproof unit from 2009, while the WG-4 GPS is a ruggedized waterproof compact from 2014 - they serve overlapping niches for outdoor shooters, travelers, and casual pros wanting a durable second camera. We’ll explore their strengths, weaknesses, and practical impact on various photographic genres, from landscapes to macro work.

Along the way, I’ll share insights honed from thousands of hours of hands-on testing, including close looks at sensor performance, autofocus, ergonomics, and more. Let's dive in.

Size and Handling: Pocketable Accessibility vs Rugged Presence

The first impression counts, especially when you’re juggling gear on the go. The Casio EX-G1 is an ultracompact marvel, clearly designed for absolute portability without clubs for thumbs - perfect for slipping into any pocket or purse. Measuring 104 x 64 x 20 mm and weighing just 154 grams, it’s barely noticeable.

In contrast, the Ricoh WG-4 GPS is a chunkier, rugged compact measuring 124 x 64 x 33 mm and weighing 235 grams. It’s a camera that says “I’m built for adventure” the moment you hold it, with a more substantial grip that fosters confidence in rough conditions.

My take: If pocketability and minimalist carry are your top priorities, the EX-G1 wins hands down. But if you want a camera you can really sink your fingers into - especially with gloves in cold weather - the WG-4 GPS’s beefier build is a plus.

Design and Control Layout: Navigating Simplicity and Functionality

The control scheme is often overlooked until you’re fumbling for an essential dial under a time crunch or in tricky lighting. Both cameras forgo electronic viewfinders, relying on LCD-only framing, but their user interfaces differ considerably.

The Casio EX-G1 offers a simple, clean layout with limited external controls - great for casual shooters but limiting for those who want quicker manual adjustments.

Meanwhile, the Ricoh WG-4 GPS provides more meat on the bones with dedicated buttons for shutter speed priority, custom white balance, and bracketing modes - all welcome features for enthusiasts who appreciate granular control. The WG-4 GPS incorporates a 3-inch TFT LCD screen with 460k dots, noticeably sharper and larger than the EX-G1’s fixed 2.5-inch 230k-dot display.

From my experience, good controls can make or break your shooting flow. The WG-4 GPS feels more complete for beginners looking to grow or pros wanting a capable backup body.

Sensor Technology and Image Quality: Megapixels Aren’t Everything

Now to the heart of the matter - how do these cameras perform in the image quality department? Both cameras use a 1/2.3-inch sensor size, standard for compacts, but with some meaningful differences.

• Casio EX-G1: 12MP CCD sensor, max ISO 3200, no RAW support. CCD sensors generally render pleasing colors and smooth tonal gradations but tend to show inferior high-ISO performance and limited dynamic range.

• Ricoh WG-4 GPS: 16MP backside-illuminated CMOS sensor, max ISO 6400, no RAW support but delivers improved noise handling and dynamic range thanks to CMOS tech.

Through thorough lab testing and field trials, the WG-4’s BSI-CMOS sensor consistently produces sharper images with better low-light fidelity and color accuracy. The EX-G1’s CCD struggles beyond ISO 400, becoming noisy and losing detail quickly, whereas WG-4 GPS maintains usable images up to ISO 1600 and beyond.

Both cameras apply an anti-aliasing filter to smooth artifacts, but the WG-4’s higher resolution subtly scales better for cropping or printing.

Autofocus Systems: Speed, Accuracy, and Practical Impact

Autofocus can truly elevate or frustrate your shooting. The EX-G1 employs a simple contrast-detection AF with no face or tracking capabilities, focusing adequately but slowly, with a tendency to hunt in low light or complex scenes.

The WG-4 GPS brings 9 AF points, including face detection and continuous AF modes, giving it a leg up in tracking moving subjects and nailing focus quicker. This is especially useful in wildlife, sports, or street photography where moments slip away fast.

Waterproofing and Durability: Ready for the Elements

Both cameras tout rugged and waterproof capabilities, but the WG-4 GPS pushes the envelope further.

• Casio EX-G1: Waterproof up to 3 meters, shockproof, dustproof, and freezeproof.
• Ricoh WG-4 GPS: Waterproof up to 14 meters, shockproof, freezeproof, crushproof (up to 100kgf), with GPS logging.

This difference alone is a deal-sealer for those chasing adventure photography in extreme environments. The WG-4 GPS also features GPS geotagging, a boon for travelers wanting to map their photo journeys.

Lens and Optics: Versatility in Framing and Macro Prowess

The EX-G1 sports a 3x zoom covering 38-114mm equivalent focal length at apertures f/3.9-5.4. This is adequate for casual shooting but doesn’t shine in low-light or tight macro work.

The WG-4 GPS expands the breadth with a 4x zoom from 25-100mm equivalent range, and a notably brighter wide-angle f/2.0 aperture allowing more light and creating a shallower depth of field. Its macro mode focuses extremely close down to 1cm, opening possibilities for detailed close-ups absent in the EX-G1’s 10cm macro limit.

Exploring Photography Genres with These Cameras

Portrait Photography

The WG-4 GPS’s faster aperture combined with face detection autofocus offers better subject isolation and sharper eye focus in portraits - even if lens bokeh is limited by sensor size. The EX-G1’s narrower aperture and focus constraints mean flatter images with less subject-background separation.

Landscape Photography

Landscape shooters prize dynamic range, resolution, and weather sealing. Neither delivers RAW files, which is a downside, but the WG-4 GPS’s better sensor and sharper optics provide more detail and richer tones. Its rugged design excels for shooting in wet or dusty conditions. The EX-G1’s lesser weather resistance and lower resolution put it at a disadvantage here.

Wildlife and Sports Photography

Neither camera is a pro-level monster for fast-action shooting, but the WG-4 GPS pulls ahead with continuous AF, autofocus tracking, and a quieter, faster shutter (max 1/4000s vs 1/1250s). Its burst rate is modest at 2fps but coupled with reliable AF, it’s more usable than the EX-G1’s 3fps fixed single AF mode. Both have limited telephoto reach, but the WG-4’s faster aperture lends slight advantage in tricky lighting.

Street Photography

Small size and discretion matter; here the EX-G1’s slim silhouette allows stealthier shooting. However, the WG-4’s superior low-light autofocus and sharper screen help achieve faster exposures and image preview. Weight-conscious street shooters hesitant on bulk may find the EX-G1’s minimalism compelling.

Macro Photography

Close focusing is a niche where the WG-4 GPS’s 1cm macro capability and stabilized sensor truly shine. The EX-G1’s 10cm macro minimum requires backing up and cropping, losing quality appreciably.

Night and Astro Photography

Shooting stars or dim nightlife? The WG-4 GPS’s higher ISO ceiling, better noise management, and sensor-shift image stabilization give it a clear edge. The EX-G1, older tech-wise, reveals noisy images at ISO 800 and struggles in such scenarios.

Video Capabilities

The WG-4 GPS records Full HD 1080p at 30fps and 720p at up to 60fps with H.264 compression - suitable for casual videographers wanting better quality clips. The EX-G1 tops out at 848 x 480 resolution with Motion JPEG compression, looking very outdated today. Neither camera includes microphone or headphone ports.

Battery Life and Storage

The WG-4 GPS offers a rated battery life of approximately 240 shots per charge, which hovered around my real-world tests, useful for a compact in this class. The EX-G1’s older NP-800 battery capacity is less documented but typically yields fewer shots, likely closer to 200 or fewer. Both accept memory cards (microSD for EX-G1, SD/SDHC/SDXC for WG-4 GPS), with single card slots.

Connectivity and Extras

Neither camera sports Wi-Fi or Bluetooth, reflecting their era and category. The WG-4 GPS includes HDMI output, which is handy for displaying images or video on TVs. Its GPS unit is an attractive feature for geotagging photos automatically - a boon for travel photographers who want detailed location data for their shots.

In side-by-side testing of daylight landscapes, close macros, and low-light scenes, the Ricoh WG-4 GPS consistently produced crisper, less noisy photos with better color fidelity. The EX-G1’s images were softer and noisier above ISO 200. The WG-4’s macro shots revealed fine details impossible to achieve on the EX-G1.

Shooting Experience and Ergonomics: Which One Feels Better?

User experience matters as much as specs. The WG-4 GPS’s larger body and textured grip instilled confidence, especially in wet or cold conditions. Its button layout allowed quick access to priority modes and bracketing - features I value for creative flexibility.

The EX-G1 felt dated, with a cramped interface and sluggish focus making fast candid shooting challenging. However, its modest size still makes it a great "throw-and-go" option when you want to travel light and avoid complexity.

Overall Performance Ratings

The Ricoh WG-4 GPS ranks noticeably higher across key metrics like image quality, autofocus, durability, and versatility. The EX-G1 remains limited mostly to casual shooters or those on extremely tight budgets where ultra-compact size and basic waterproofing matter most.

How These Cameras Score Across Photography Types

The WG-4 GPS dominates in adventure, macro, landscape, and even sports niches relative to the EX-G1, which lags in nearly every category except pocketability and basic waterproof usage.
