Choosing the right camera is always a blend of art and science - involving sensor technology, handling comfort, intended use case, and budget. Today, we’re pitting two intriguing yet different systems against each other: the Casio EX-ZR800, a compact superzoom released in 2013, and Ricoh GXR A16 24-85mm, an advanced mirrorless camera from 2012 with a modular sensor-lens array. Through extensive hands-on testing across varied photography disciplines, I’ll draw out the practical differences, strengths, and drawbacks of these two cameras. We’ll uncover who each one serves best, backed by technical scrutiny and real-world shooting experience.

Understanding the Cameras at a Glance: Compact Versus Mirrorless

Before diving deep into specs and image quality, it's essential to position these cameras in their respective categories.

The Casio EX-ZR800 is a compact, small-sensor superzoom aimed at travelers and casual shooters who desire massive zoom range (25-450mm equivalent) in a pocketable body. Its 1/2.3" sensor is typical for compact cameras, delivering modest image quality suited for web sharing and snapshots.

Conversely, the Ricoh GXR A16 24-85mm operates in the advanced mirrorless realm, sporting an APS-C sensor (the same size as many DSLRs) and a fixed zoom lens on its module. The modular design means you cannot swap the zoom for other lenses without changing the sensor block, limiting system flexibility but offering better image quality than typical compact cameras.

At first glance, the size and weight differential is evident - Casio’s EX-ZR800 is compact and lightweight (108x60x31 mm, 222g), while Ricoh’s GXR is bulkier and heavier (114x75x93 mm, 550g). This affects not just portability but handling comfort and stability, which we will explore later.

Sensor Technology and Image Quality: Size Matters, But So Does Processing

Sensor size is the most substantial factor differentiating these cameras.

The Casio EX-ZR800 uses a 16MP CMOS sensor with a tiny 1/2.3" (6.17x4.55mm) sensor area (approx 28.07 mm²). These are found in many superzoom compacts and prioritize zoom reach and portability over ultimate image quality. Smaller sensors have smaller photosites, often resulting in more noise at higher ISOs and limited dynamic range.

Meanwhile, the Ricoh GXR A16 module boasts a much larger APS-C sensor (370.52 mm²) with the same 16MP resolution. Larger sensor area equates to bigger photosites capable of capturing more light, yielding better low-light performance, higher dynamic range, and more detailed images even at equivalent resolution.

Real-world Image Quality

In practical use, here’s what this means:

• Dynamic Range: The Ricoh's APS-C sensor handles high-contrast scenes far better, preserving highlight and shadow detail with more natural gradations. In landscapes with bright skies and shaded foregrounds, the GXR captures balanced exposures, whereas the Casio’s smaller sensor shows clipped highlights or muddy shadows.

• Noise Performance: Both cameras cap at ISO 3200 native, but the Ricoh produces notably cleaner images above ISO 800. The Casio’s images get blotchy and lose texture quickly after ISO 400, limiting its use in dim environments.

• Resolution and Sharpness: Although both share a 16MP count, Ricoh’s larger sensor permits cleaner, more detailed files without aggressive noise reduction. The Casio's compact lens and smaller sensor pairing deliver noticeably softer results at longer focal lengths, especially zoomed-in landscapes or portraits where fine detail is prized.

• Colour Depth: Both models include anti-alias filters, which slightly soften images to prevent moiré, although Ricoh’s more advanced Smooth Imaging Engine IV helps retain colour fidelity and subtle tonal transitions, beneficial for skin tones in portraiture.

Handling and Ergonomics: Comfort is King in Extended Use

Despite Ricoh GXR’s larger footprint and weight, it compensates with a solid grip and thoughtfully placed controls reminiscent of rangefinder cameras. Dedicated exposure compensation dials, physical manual focus rings on the lens, and a responsive shutter button facilitate deft control over exposure parameters.

The Casio EX-ZR800 prioritizes simplicity and pocketability, featuring a minimalist control layout and a fixed 3-inch LCD without touchscreen support. Button layout is somewhat cramped due to its compact frame, and its grip can feel a little insubstantial during extended shoots or at longer zoom settings.

Viewing Experience: LCD and Viewfinder Insights

Neither camera includes a built-in optical or standard electronic viewfinder, but Ricoh offers an optional electronic viewfinder accessory. The Casio entirely lacks any EVF option, relying on its rear screen alone.

Both have fixed 3-inch LCDs around 920x920 resolution. The Casio’s Super Clear TFT color LCD gives vibrant on-location previews but can be challenging to view in bright sunlight due to reflective properties.

Ricoh’s TFT LCD performs slightly better outdoors, thanks to subtle anti-reflective coatings and a well-calibrated color profile, aiding accurate framing and exposure assessment. The absence of a native EVF on Ricoh feels like a limiting factor for serious shooters used to composing via viewfinder, but the modular accessory partially compensates.

Autofocus Systems: Precision vs. Speed

Neither camera includes advanced phase-detection autofocus systems typical of modern mirrorless models, but their contrast-detection AF implementations differ.

The Casio EX-ZR800 employs contrast detection with face detection and center-weighted AF. However, autofocus area options are fairly limited, and AF can feel sluggish - especially in low light or long zoom conditions, with hunting occasionally noticeable. It lacks continuous AF during video and burst modes.

In comparison, the Ricoh GXR A16 offers contrast detection with multi-area AF, face detection, and manual focus assistance via focus peaking. It supports both single and continuous AF modes, which is advantageous for tracking moving subjects, though it isn’t specialized for fast sports or wildlife photography.

For static scenes, Ricoh’s AF is more precise and quicker to lock focus, albeit neither camera shines in demanding AF scenarios given their age and sensor tech focus.

Zoom Range and Lens Performance: Superzoom vs. Moderate Flexibility

The Casio EX-ZR800 boasts an extremely impressive 25-450mm (18x) zoom range with a maximum aperture of f/3.5-5.9. This lets you cover wide to super-telephoto framing without changing lenses - very handy for travel and casual shooting but comes with optical compromises. Lens sharpness noticeably declines at full telephoto, and aperture narrowing reduces low-light ability.

Ricoh’s GXR A16 module has a more modest zoom 24-85mm (3.5x) lens with f/3.5-5.5 aperture. While less ambitious in reach, the lens optic quality is noticeably better with excellent edge-to-edge sharpness and less distortion. The modular system does not allow switching lenses within the same body, which limits flexibility but keeps image quality high for the supplied modules.

Burst Shooting and Low Light Performance

Both cameras offer 3 frames per second continuous shooting - a relatively modest speed today, suitable for occasional action but not optimized for sports or wildlife professionals.

Low light performance stacks in favor of the Ricoh GXR's larger sensor and more refined image processing, which allows usable images at ISO 1600 and above. The Casio’s sensor and lens combo produces heavy noise above ISO 400, forcing wider apertures or slower shutter speeds that introduce blur or camera shake even with its in-body sensor-shift stabilization.

Specialized Areas of Use

Portrait Photography: Rendering Skin and Bokeh

The Ricoh GXR’s APS-C sensor naturally creates more pleasing bokeh thanks to shallower depth of field at equivalent focal lengths. Its lens delivers clean, natural skin tones and rendering that benefits from the richer color depth of the larger sensor.

Casio’s smaller sensor and lens design emphasize greater depth of field, making background separation more difficult. Skin tones are decent but can look flat with the camera’s more aggressive in-camera sharpening and noise reduction.
