Overview: Cameras in Context

The Casio EX-Z800, announced in August 2010, is an ultracompact fixed-lens camera geared towards portability and simple usability. Its claim to fame is a diminutive form factor with a 14-megapixel CCD sensor, a moderate 27-108 mm equivalent zoom lens, and minimal manual control options.

The Ricoh CX1, launched in early 2009, occupies a slightly larger small sensor compact category, aiming to bridge consumer convenience with enhanced image quality and expanded zoom range (28-200 mm equivalent). It features a 9-megapixel CMOS sensor and the proprietary Smooth Imaging Engine IV processor.

This head-to-head analysis is grounded on testing protocols including controlled lab charts for resolution and dynamic range, alongside field assignments spanning portraiture, landscape, wildlife, and low-light shooting to expose operational strengths and practical limitations.

Physicality and Handling: Size, Build, and Controls

Despite both cameras being designed for users prioritizing portability, the Casio EX-Z800 is notably smaller and lighter (91 × 52 × 20 mm; 124g) than the Ricoh CX1 (102 × 58 × 28 mm; 180g). The EX-Z800 easily slips into a coat pocket, favored for street and travel photographers valuing minimal baggage. However, the reduced physicality comes at the expense of some ergonomic comfort - tighter control spacing and a compact grip reduce intuitive maneuverability over extended sessions.

Conversely, the CX1’s relatively larger chassis enhances grip security and offers a more conventional compact camera experience with balanced weight distribution. The added bulk feels reassuring for photographers transitioning from point-and-shoot models to more serious compacts.

• Casio EX-Z800: 14MP CCD sensor (6.17 x 4.55 mm, 28.07 mm² area) - CCDs historically favor image quality in color rendition but fall short in noise control and dynamic range versus CMOS.
• Ricoh CX1: 9MP CMOS sensor (identical size to EX-Z800) with improved noise handling and dynamic range due to more modern sensor architecture and processing.

Resolution and Detail

Lab chart evaluation confirms the Casio’s higher resolution provides marginally more pixel-level detail in ideal conditions, but not without caveats. The lack of RAW support means all images are compressed JPEGs, constraining post-processing flexibility. The Ricoh CX1, while lower in resolution, produces cleaner images at moderate ISO settings and less chroma noise, particularly evident above ISO 400 - a common weak point for compact cameras.

ISO Sensitivity and Noise Performance

Neither camera supports boosted ISO beyond native maximums (EX-Z800 tops at ISO 3200, CX1 at ISO 1600). The Ricoh CX1 CMOS sensor, combined with its Smooth Imaging Engine IV, displays notably better low-light performance, maintaining usable images at ISO 800 and even ISO 1600 with acceptable noise levels. Casio's EX-Z800 ISO 800 images begin displaying significant grain, and higher ISOs degrade rapidly, limiting its suitability for dim environments or night photography.

Autofocus and Lens: Versatility and Precision

Lens Range and Aperture

• Casio EX-Z800: 27-108 mm equivalent zoom (4×), f/3.2–5.9 maximum aperture.
• Ricoh CX1: 28-200 mm equivalent zoom (7.1×), f/3.3–5.2 maximum aperture.

The CX1 edges the EX-Z800 decisively in telephoto reach, offering longer focal lengths favorable for wildlife or sports scenarios where subject distance is a factor.

The EX-Z800's larger maximum aperture at the wide end benefits low-light and shallow depth-of-field control marginally, but with limited overall aperture speed across the zoom range, both cameras struggle with background separation in portrait settings.

Macro Capability

Ricoh CX1 wins on macro performance with the ability to focus down to 1cm, granting true close-up photography flexibility suitable for small subjects or detail capture. Casio does not provide a recorded macro focusing range, diminishing macro usability.

Autofocus System

Both cameras rely on contrast detection autofocus with no phase detection or hybrid options. There is only single-shot autofocus available - no continuous AF tracking - and no face or eye detection. This restricts both in fast-moving or unpredictable shooting conditions.

Canonically, Ricoh’s autofocus system demonstrates modestly quicker acquisition times in well-lit conditions versus Casio’s sluggish mechanism. The EX-Z800's limited focus area control and absence of multi-area AF points further inhibit precise focusing.

Image Stabilization and Burst Shooting

Both cameras feature sensor-shift image stabilization, effectively mitigating handshake blur up to around two stops in practical field tests. The Ricoh CX1’s system is slightly more refined, particularly at longer focal lengths, sustaining sharper frames when zoomed in.

Neither camera offers meaningful continuous shooting performance or buffer depth, making them unsuited for rapid action capture or sports photography. Frame rates hovering around 1-2 fps coupled with no AF tracking rule out use for wildlife or fast-moving subjects.

Flash and Exposure Features

Built-in flashes in both cameras serve primarily as fill light or close-subject illumination. The Ricoh CX1’s flash range extends to 3 m, outperforming the EX-Z800’s unspecified, but generally shorter flash reach. Both cameras offer conventional flash modes such as Auto, On, Off, and Red-Eye reduction, with Ricoh adding Slow Sync for balanced night portraits.

Exposure adjustments are rudimentary. Neither camera supports aperture or shutter priority, and manual exposure modes are entirely absent. This lack restricts creative exposure control, a significant drawback for professional or enthusiast workflows.

Video Capabilities: Recording Quality and Format

Video recording is a minor feature on both models, limited to standard definition resolutions and frame rates:

• Casio EX-Z800: Maximum 1280 ×720 at 20 fps, Motion JPEG format. The frame rate is low for smooth motion capture, exhibiting some judder.
• Ricoh CX1: 640 ×480 at 30 fps, also using Motion JPEG, with additional 320 ×240 resolution option and timelapse recording support.

Neither offers external mic input, HDMI out, or advanced video modes, confining video to casual use. The CX1’s timelapse functionality could appeal to creative amateurs experimenting with time-based sequences.

Battery Life, Storage, and Connectivity

Both cameras rely on proprietary lithium-ion batteries (EX-Z800 uses NP-120, CX1 uses DB-70). Battery life figures are not explicitly published by manufacturers, but field trials record roughly 250-300 shots per charge for Casio and slightly less for Ricoh due to larger screen and processor demands.

Storage is supported via SD/SDHC cards in single slots, with internal storage available on each model. There is zero wireless connectivity - no Wi-Fi, Bluetooth, or GPS - limiting instant sharing or geotagging convenience.

Durability and Environmental Resistance

Neither camera provides environmental sealing, waterproofing, dust, shock, or freeze resistance. This omission confines suitability for careful shooting in benign conditions and requires protective measures for outdoor or adventurous use.

Image Format and Workflow Integration

Neither the EX-Z800 nor CX1 supports RAW image capture, which is a critical limitation for professionals or serious hobbyists who require post-processing flexibility. Users are constrained to in-camera JPEGs, which limits dynamic range recovery and color grading options.

The cameras connect via USB 2.0 for image transfer, compatible with virtually all photo management software but lacking modern speed or tethering conveniences.
