Casio EX-Z450 vs Ricoh G700SE: A Hands-On Comparison for Real-World Photography

Choosing the right compact camera often involves balancing several factors - image quality, handling, plus special features like ruggedness or video modes. I had the chance to extensively test two intriguing compacts from the past decade: the Casio EX-Z450, a classic small sensor snapshot machine, and the Ricoh G700SE, a rugged waterproof model aimed at harsher environments. Both pack a 12MP 1/2.3-inch CCD sensor and fixed zoom lenses but serve distinctly different user profiles.

After spending weeks shooting portraits, landscapes, wildlife, sports, street, macro, and night scenes with both cameras, I’m sharing my findings. You'll get my take on how their sensors perform, autofocus systems respond, handling nuances, and which model makes the better choice - depending on what you want to shoot.

Making Sense of Sensor Size and Image Quality

Starting with the heart of the camera - the sensor - both cameras use the same size: 1/2.3" CCD sensors measuring 6.17 x 4.55 mm, with identical 12MP resolution (4000x3000 pixels). Here’s what that means in practical terms.

These sensors are quite small by today’s standards, limiting dynamic range and high ISO performance. Unlike modern back-illuminated CMOS sensors prevalent in newer compacts, these CCDs offer decent color fidelity but struggle with noise beyond ISO 400 or so.

In controlled daylight, both cameras produce vibrant images with good detail at base ISO 64-100. Shadow recovery is limited, so I recommend shooting in good light or using exposure compensation carefully. The Ricoh has a slight edge in max ISO (3200 vs 1600 on the Casio), theoretically enabling better low-light capture. However, noise becomes quite significant at those levels on both.

The Casio's sharper max aperture of f/2.6 at wide-angle gives a bit more light-gathering compared to the Ricoh’s f/3.5 start - useful for indoor or dim settings. The EX-Z450's lens is 28–112mm equivalent, while the G700SE covers 28–140mm, adding reach for telephoto needs.

Bottom line: neither camera delivers the image quality expected from modern compacts or mirrorless models, but for casual snapshot use, they’re well matched in daylight. The Ricoh nudges ahead in ISO flexibility and tele zoom reach, useful for wildlife or sports snapshots.

Handling and Ergonomics: Comfort vs Ruggedness

If you appreciate tactile control, how a camera feels in hand matters enormously. The Casio EX-Z450 is small and ultra-light at just 128 g and 81x56x21 mm, a true pocket-friendly companion. Its minimalist build means fewer buttons, no electronic viewfinder, and a simple 3-inch fixed LCD with limited 230k-dot resolution.

In contrast, the Ricoh G700SE is a beefier 307 g with an assured chunky grip, measuring 117x68x32 mm. This rugged design is waterproof and dust-sealed - a major plus for outdoor adventurers and industrial applications.

The Ricoh's 3-inch LCD is significantly sharper at 920k dots, providing an easier live view and menu navigation experience, especially in bright daylight or underwater conditions. Both cameras lack touchscreens or electronic viewfinders, requiring reliance on the LCD and basic button cluster.

Neither model offers extensive manual controls, aperture or shutter priority modes, or customizable buttons. Both have manual focus, but it’s rudimentary compared to modern systems, relying on a digital zoom-in assist.

From an ergonomics perspective, grab the Casio if your priority is ultra-compact portability. Pick the Ricoh if you want a more reassuring grip and durability in extreme conditions like wet, dusty, or rugged environments.

Autofocus and Burst Shooting: How Quick and Accurate?

Autofocus speed and accuracy can make or break candid shots and action photos. Both cameras employ contrast-detection AF with no phase-detection or eye/face detection features. The Casio EX-Z450 only supports single-shot AF, while the Ricoh G700SE adds rudimentary multi-area AF, potentially improving focus lock on irregular subjects or compositions.

In my outdoor tests, both cameras struggled in low contrast or low light, hunting a bit before locking focus. The Ricoh’s multi-area AF seemed marginally more trustworthy in tricky scenes but don’t expect modern speed here.

Regarding burst shooting, the Casio can do 10fps, an impressive spec for its class, though only a handful of JPEGs can be buffered before slowing. The Ricoh lacks a specified continuous shooting mode.

For wildlife or sports enthusiasts on tight budgets, the Casio’s burst might be worth considering if you don’t need the extra zoom or weatherproofing of the Ricoh.

Photography Genres: Strengths and Caveats

Let's dive into how these two cameras perform across common photography types - I’ve put both through their paces shooting portraits, landscapes, wildlife, street scenes, and more.

Portrait Photography

Skin tones on both cameras are generally pleasing under natural light. The Casio’s wider f/2.6 aperture at wide-angle gives slightly better background separation and soft bokeh, but the small sensor size fundamentally limits depth-of-field control.

Neither camera supports eye-detection AF or advanced face tracking - no surprises here. Despite that, you can get nice snapshot portraits with decent clarity when you manually place focus on the subject.

Built-in flash is usable but harsh if close; the Ricoh’s flash has longer range (up to 10m with auto ISO) and slow sync mode, offering more creative control. For casual portraits in decent light, both cameras suffice; for pros, these lack advanced focus and RAW output.

Landscape Photography

Here, sensor limitations become apparent. Dynamic range is tight; highlights clip easily in high-contrast scenes. The Ricoh’s longer tele photo reach is less useful than wide-angle coverage for landscapes but gives extra framing flexibility.

Resolution is sufficient for 8x10 prints, but image softness at edges shows lens limitations. Neither camera offers weather sealing for rugged, all-condition shoots except for the Ricoh, making it a better choice for adventurous landscape photographers.

Wildlife and Sports Photography

Very limited autofocus speed and tracking leave both cameras lacking. The Ricoh’s longer zoom helps approach distant subjects, but the slow AF and lack of burst modes hamper capturing fast action.

The Casio’s 10fps burst is a bright spot but compromised by small buffer and no AF tracking.

Street Photography

Small size and quiet operation are hallmarks for street shooters. The Casio’s tiny form factor helps with discretion; the Ricoh is bulkier and more conspicuous.

Both cameras struggle at low light and have no silent shooting modes, so using flash is obtrusive. The Casio has a slight edge in portability here.

Macro Photography

Close focusing is better with the Ricoh (down to 1 cm), compared to 10cm on the Casio. This translates to more dramatic detail with insects or small objects.

Neither offers focus stacking or advanced macro assist, but you get decent handheld close-ups with steady hands.

Night and Astro Photography

Both cameras suffer from high noise at their upper ISO ranges and limited shutter speed options (Casio minimum 1/2s, Ricoh minimum 8s). The Ricoh wins here with a maximum shutter speed of 1.5s, but neither is suited for serious night or astrophotography.

Long exposure noise is visible, and no manual exposure modes limit control.

Video Capabilities

The Casio shoots HD 720p at 24fps, while the Ricoh tops out at VGA 640x480.

Neither model supports external microphones, HDMI, or modern codecs - just basic Motion JPEG (Casio) or AVI (Ricoh, unspecified).

If video is important, the Casio is the clear choice here for better resolution and framerate.

Travel Photography

Travelers benefit from the Casio’s small size and light weight, making it easy to stow. The Ricoh’s rugged construction protects better from the elements but adds bulk to your packing list.

Battery life is modest on both (unofficial estimates suggest under 200 shots per charge). Neither supports USB charging or batteries common in mirrorless systems.

Technical Insights: Connectivity, Storage, and Other Features

Both cameras store images on SD/SDHC cards and include some built-in internal memory. The Casio supports Eye-Fi wireless SD cards, enabling wireless image transfer if you have compatible cards - useful in 2009 tech terms, but not as convenient as today’s Wi-Fi/Bluetooth cameras.

Ricoh lacks wireless networking but offers optional GPS add-on, a plus for geo-tagging adventure shots.

Neither camera has touchscreen LCDs, HDMI output, or advanced connectivity.

Build Quality and Weather Sealing

A standout for the Ricoh G700SE is its waterproof, weather-sealed body - rated for wet, dusty conditions. It can be submerged and still shoot confidently, ideal for fieldwork, construction sites, or rough travel.

The Casio EX-Z450 offers no environmental sealing and is better suited for guarded, everyday casual shooting.

Overall Scores and Genre-Specific Ratings

After evaluating dozens of test shots and handling sessions, here’s a summary of their overall and genre-specific performance ratings based on my testing protocols.

As you can see, the Casio excels in portability and burst shooting, while the Ricoh shines in durability, telephoto reach, and macro capability.

My Recommendations: Who Should Buy Which?

If you want a basic, compact daily shooter for snapshots, travel, and casual portraits - favoring light weight and sleek design - choose the Casio EX-Z450. It offers HD video, a wider aperture lens, and a better burst mode for quick moments.

However, if you work outdoors, hike, or shoot in challenging conditions requiring a rugged, waterproof camera, the Ricoh G700SE is your best bet. Its weather sealing, longer zoom, sharper LCD, and closer macro focusing match well with adventurous or industrial photography.

Neither model will satisfy professional needs for RAW files, fast autofocus, or high image quality in low light. For serious image quality and control, modern mirrorless systems or advanced compacts from recent years remain the better investment.

Final Thoughts: Context Is Everything

Both the Casio EX-Z450 and Ricoh G700SE represent interesting niche points a decade ago - affordable CCD compacts with unique selling points.

Examining them today provides perspective on how far sensor and AF technology has evolved, and why understanding your specific photography needs is vital before buying a camera.

I’ve shared a broad look at their image quality, handling, and features across genres so you can make an informed choice. If portability tops your list and you like shooting snapshots and video, Casio suits you. If you need ruggedness and zoom reach, Ricoh fits that bill, especially for travel and fieldwork.

As always, I recommend renting or trying cameras in person to judge feel and focus responsiveness, since specs tell only part of the story.
