Sensor specifications: 1/2.3” sensor (Canon) vs APS-C sensor (Ricoh) with drastically different image quality implications

Sensor Technology and Image Quality Comparison

The heart of any camera is its sensor, and here is where these two diverge fundamentally:

What the Numbers Mean in Practice

The Ricoh’s APS-C sensor is over 13 times larger in area than Canon’s 1/2.3-inch sensor. This directly translates into superior image quality: higher detail resolution per pixel area, lower noise at higher ISO values, and wider dynamic range for retaining shadows and highlights.

While the Canon boasts a higher megapixel count on a much smaller sensor, this often results in more noise, less tonal richness, and difficulty in low light conditions. The Canon excels in daylight or well-lit situations but shows limitations beyond ISO 800 to 1600. The Ricoh’s larger sensor means cleaner, more professional-grade images, especially noticeable in portrait and landscape photography.

Shooting Experience: Autofocus, Control, and Viewfinder

Autofocus System

• Canon SX70 HS uses contrast-detection autofocus with 9 focus points (including face detection and tracking), supporting single, continuous, and tracking modes for moving subjects, plus manual focus.
• Ricoh GXR Mount A12 relies similarly on contrast-detection AF but lacks face/eye detection and tracking features. It has selective AF area options but no continuous tracking autofocus.

In real-world testing, the Canon SX70 HS provides a more responsive and reliable autofocus for moving subjects, wildlife, and sports scenarios thanks to its specialized algorithms and dedicated AF points.

Controls and Operation

Canon’s dedicated dials for exposure compensation and convenient mode dial simplify on-the-fly adjustments. The fully articulated screen helps for unusual angles or video work.

Ricoh offers a cleaner, simplified interface, better suited for deliberate, composed photography rather than fast-action or run-and-gun approaches.
