Analyzing the control surface reveals contrasts in user interaction. The Ricoh CX4 houses a minimalist control set: a mode dial limited to automatic and scene selections, combined with a joystick-style 4-way controller for adjustments. It lacks direct shutter speed, aperture, or ISO buttons, reflecting its novice-oriented design.

Conversely, the Sony A380 provides a traditional DSLR interface with a dedicated mode dial granting access to shutter priority (S), aperture priority (A), manual (M), and program (P) exposure modes. ISO sensitivity adjustments, white balance, and exposure compensation controls are directly assignable. The presence of an optical pentamirror viewfinder coincides with an ergonomically placed shutter release button and instinctively reachable dials for exposure control - features that enhance operational speed and customization for enthusiasts and professionals.

Sensor Specifications and Image Quality Fundamentals

Here lies the most pivotal difference, fundamentally shaping image quality and photographic potential.

Sensor Size and Type:

• Ricoh CX4 incorporates a 1/2.3" back-illuminated CMOS sensor measuring 6.17 x 4.55 mm with an area of 28.07 mm².
• Sony A380 uses a significantly larger APS-C sized CCD sensor at 23.6 x 15.8 mm, an area of 372.88 mm², roughly 13 times larger.

The sensor size advantage inherently favors the A380 in resolution, dynamic range, low-light performance, and depth of field control. CCD technology, while considered more power-hungry and slower at readout compared to CMOS, delivers excellent color fidelity and tonal gradation but with less flexibility for video and burst shooting.

Resolution:

• CX4 offers 10 MP (3648 x 2736 max resolution).
• A380 provides 14 MP (4592 x 3056 max resolution).

Though the megapixel difference is moderate, the larger A380 sensor pixels gather more light, contributing to lower noise and greater tonal latitude.

ISO and Noise Performance:
Both cameras have a native ISO range from 100 to 3200; however, the A380’s larger sensor and CCD architecture yield superior noise control at higher sensitivities, practically doubling effective ISO usability compared to the CX4’s small sensor, which suffers noise proliferation above ISO 400 due to limited pixel size and sensor area.

Detailed tests confirm the CX4’s noise profile becomes aggressively grainy past ISO 400, restricting low-light usability. The A380 maintains usable, cleaner images up to ISO 800 and acceptable up to 1600, albeit with noticeable grain.

LCD Screen and Viewing Experience: Fixed vs Tilting Displays

The Ricoh CX4 sports a fixed 3-inch LCD with 920,000 dots resolution, delivering bright, sharp reflections suitable for outdoor usage, albeit at non-touchscreen functionality. Its fixed position constrains shooting angles, especially for low or overhead perspectives common in macro or street photography.

The Sony A380 features a 2.7-inch tilting LCD with a modest 230,000 dots resolution - a significant drop in pixel density compared to the CX4. The tilting mechanism aids composition from difficult angles. The absence of touchscreen reduces intuitive interactions but is common in DSLRs of that era. The A380’s use of an optical pentamirror viewfinder with 95% coverage and 0.49x magnification allows traditional eye-level framing, reducing strain under bright conditions and providing an uninterrupted view, which the CX4, lacking a viewfinder, cannot offer.

Autofocus Systems: Precision, Speed, and Tracking Capabilities

The Ricoh CX4’s autofocus relies exclusively on contrast-detection technology without phase-detection or hybrid AF mechanisms. Its fixed lens coupled with limited focus areas (multi-area contrast AF and center-weighted) and absence of face or eye detection constrain its accuracy and speed, especially in low contrast or low light.

The Sony A380 employs a dedicated phase-detection AF system featuring 9 focus points, supporting continuous AF in live view and support for face detection, enhancing tracking of moving subjects. Although the number of cross-type points is unspecified, the Sony’s AF generally surpasses the CX4 in predictability and responsiveness, particularly relevant for sports and wildlife shooting.

Continuous autofocus and selective area AF allow the A380 to lock focus effectively in fast-moving scenarios - a decisive advantage in dynamic photography. The CX4 lacks AF tracking or continuous focus modes, limiting its usability in action shots.
