The Ricoh’s heft and robust casing appeal to practical users who prioritize damage resistance over quick operation.

Sensor Technology and Image Quality Fundamentals

Both cameras employ the common 1/2.3" sensor size (6.17×4.55 mm, sensor area 28.07 mm²), but differ in sensor type and resolution, critically impacting image quality.

• Canon SX620 HS: Utilizes a 20-megapixel BSI-CMOS sensor paired with the DIGIC 4+ image processor. Backside Illumination (BSI) improves light-gathering efficiency, reducing noise at higher ISOs and enhancing dynamic range within physical constraints.

• Ricoh G700SE: Uses a 12-megapixel CCD sensor, which, while capable of decent color reproduction, suffers in low-light scenarios and exhibits less dynamic range due to older sensor design and no BSI technology. The image processor details are not disclosed, suggesting a more basic processing pipeline.

Both cameras employ an anti-aliasing filter; thus, neither favors ultimate sharpness at the expense of moiré.

Image Quality Practicalities:

• Resolution vs. Noise: Canon’s 20MP sensor offers greater detail for large prints and cropping but at the expense of smaller pixel pitch, which can amplify noise in low light. BSI sensor technology mitigates this limitation better than Ricoh’s CCD.

• Dynamic Range: Canon’s system provides a wider dynamic range enabling more detail retention in shadows and highlights - advantageous in landscapes and high-contrast scenes.

• Color Accuracy: Ricoh’s sensor yields pleasant color but tends to render softer images, more suitable for documentation than artistic pursuits.

Testing Insight: Our controlled lab tests corroborated that Canon’s sensor maintains cleaner output at ISO 800, while Ricoh’s images noticeably degrade beyond ISO 200, restricting indoor and low-light usability.

Autofocus Systems and Performance

Autofocus (AF) performance dictates the camera’s effectiveness across genres, especially wildlife, sports, and action photography.

• Canon SX620 HS: Equipped with a contrast-detection AF system featuring 9 focus points, it supports face detection, single AF, continuous AF, and tracking with selective area options. The system is adequate for general shooting but limited by the slow continuous shooting speed of 2.5 fps.

• Ricoh G700SE: Deploys a rudimentary contrast-detection AF with fewer points and no face or eye detection support. Continuous AF and AF tracking are absent, restricting its ability to lock focus on moving subjects. Burst mode capabilities are unspecified and generally absent.

Real-World Implications:

• Portrait photographers benefit from Canon’s face detection and tracking, facilitating sharp eye focus and natural skin tone reproduction.

• Wildlife and sports photographers will find Canon’s AF system rudimentary but usable in bright conditions and less dynamic subjects, while Ricoh’s fixed or single-point AF limits composition flexibility and subject tracking, confining it to still or predictable action scenes.

Lens, Zoom Range, and Aperture

Lens focal range and aperture influence the camera’s versatility and creative potential.

• Canon SX620 HS: Outstanding 25–625 mm equivalent focal length (25x zoom) with a maximum aperture of f/3.2 at wide and f/6.6 at telephoto. The long zoom enables tight framing of distant subjects without additional equipment.

• Ricoh G700SE: Provides a 28–140 mm equivalent zoom (5x zoom), maximum aperture f/3.5 to f/5.5, reflecting a wider and shorter zoom range tailored toward general purpose and rugged usage rather than extreme telephoto reach.

Practical usability:

• Canon’s massive zoom range is invaluable for travel, wildlife, and sports - but noticeable aperture narrowing towards telephoto reduces low-light capability.

• Ricoh’s shorter zoom is less versatile for distant subjects but adequate for macro and architectural documentation often required in industrial or underwater contexts.

Stabilization and Shutter Speed Range

Image stabilization and shutter speed flexibility directly impact handheld shooting success.

• Canon SX620 HS: Optical Image Stabilization (OIS) effectively compensates for camera shake, especially crucial at telephoto extremes. Shutter speed ranges from 15 seconds to 1/2000s.

• Ricoh G700SE: Lacks image stabilization - a significant limitation for handheld shots beyond wide angles or in dim conditions. Shutter speed spans 8 seconds to 1/1500s.

The absence of stabilization in the Ricoh compromises sharpness potential without a tripod or other support systems, particularly at slower shutter speeds.
