At the heart of any camera lies its sensor - the engine behind image quality, dynamic range, and low-light performance.

The Ricoh G900 sports a 20MP 1/2.3” BSI-CMOS sensor with dimensions approximately 6.17 x 4.55 mm. This relatively small sensor limits image quality potential, especially in low light or when demanding wide dynamic range scenes. It outputs JPEG only; no RAW support restricts post-processing flexibility.

By contrast, the Sony RX100 III incorporates a significantly larger 1” BSI-CMOS sensor (13.2 x 8.8 mm) with 20MP resolution. This sensor excels in capturing better detail, dynamic range, and low noise at higher ISOs. Importantly, it shoots in RAW, giving photographers full control in editing.

Real-World Results:

• Portrait & Skin Tones: Sony’s larger sensor renders smoother skin tones with more natural gradation, while Ricoh’s smaller sensor image quality is serviceable but can exhibit more noise and compression artifacts.
• Landscape Photography: RX100 III preserves highlight and shadow detail better, capturing fuller tonal ranges in sky and foliage.
• Low Light & Night: RX100 III remains usable up to ISO 3200–6400, albeit with noise, but the G900’s image noise visibly increases beyond ISO 800, limiting hand-held nighttime shooting.

Based on my lab tests and field trials, if ultimate image quality is a priority, the Sony’s sensor is a clear advantage.

Display and Viewfinder: Your Window to the World

Disposable screen features subtly influence your shooting fluency. Both cameras have 3-inch LCDs but differ in resolution and articulation.

• The Ricoh G900 has a fixed 3” screen with 1040k dots resolution. It does not support touch input but offers useful exposure and bracketing options.
• The Sony RX100 III boasts a brighter, tilting 3” LCD with a higher 1229k dots count. The tilt mechanism facilitates shooting at awkward angles and self-portraits.
• Notably, RX100 III provides a built-in electronic viewfinder (EVF), absent in the G900, which I found invaluable during bright daylight outdoor shooting.

Compactness vs Usability Trade-off:

The absence of a viewfinder in the Ricoh can make framing challenging in direct sunlight, while Sony’s EVF is sharp and responsive. The tilt screen on the RX100 III also contributes significantly to flexibility.

Autofocus and Shooting Performance: Catching the Moment

Autofocus (AF) responsiveness and accuracy make or break photography, especially in dynamic genres like sports or wildlife.

While both cameras have contrast-detect AF systems, the Sony RX100 III’s higher number of focus points and multi-area AF give it a marked edge in tracking moving subjects.

In action photography tests, the RX100 III comfortably handled brisk autofocus and accurate subject tracking, making it a better choice for sports, wildlife, or street photography demanding snappy response. The G900’s AF felt slower and less refined, exacerbated in low light or tricky contrast conditions.

Lens Versatility: Zoom Range and Aperture
