Sensor Technology: Size Matters, But So Does Design

At the heart of image quality lies the sensor, and here the cameras diverge radically.

The Ricoh GR II sports an APS-C CMOS sensor sized 23.7 x 15.7mm with a 16-megapixel resolution. While not cutting-edge by today’s standards, this sensor offers a nice balance of detail and noise control for its size and market segment. The GR II’s sensor includes an anti-aliasing filter, which helps reduce moiré but slightly softens fine detail.

The Sony A7 III features a much larger full-frame BSI-CMOS sensor measuring 35.8 x 23.8mm with 24 megapixels. Its backside-illuminated design aids low-light sensitivity and dynamic range. Thanks to its larger sensor area (852 mm² vs 372 mm²), it captures more light per pixel, resulting in superior image clarity, cleaner high-ISO shots, and richer color depth.

In tests, the A7 III outperforms the GR II in:

• Dynamic range (14.7 EV vs 13.7 EV) - allowing better detail recovery in shadows and highlights.
• Color depth (25 vs 23.6 bits) - richer gradations and more subtle tones.
• Low-light ISO (native 100–51200, expandable to 204800 vs 25600 max) - cleaner, more usable high-ISO images.

While the GR II’s sensor holds up well for a compact, it simply cannot match the full-frame power house in dynamic range or noise performance.

Sensor and Image Quality Takeaway:
For portraits, landscapes, and scenarios requiring fine detail or noise resistance, the Sony A7 III dominates. The Ricoh GR II is excellent for daylight and well-lit conditions, particularly street and travel photography where portability is prized.

Autofocus and Performance: Speed vs Simplicity

Autofocus (AF) capabilities are critical in action-oriented photography fields. Here the gap widens.

The Ricoh GR II employs contrast-detection AF with 9 focus points and face detection. It supports single, continuous, and tracking autofocus modes but lacks modern hybrid or phase-detection points. This system is adequate for casual shooting and stationary subjects but can struggle tracking fast-moving subjects - making it less ideal for sports or wildlife.

Sony’s A7 III brings a sophisticated AF system, boasting 693 phase-detection points covering a wide area and 425 contrast-detection points. It supports:

• Real-time Eye AF (also for animals)
• Advanced subject tracking with excellent precision
• Fast AF acquisition (under 0.05 sec)
• 10 frames per second burst shooting with continuous AF/AE

From hands-on experience, the A7 III’s tracking accuracy and speed handle rapid sports sequences, unpredictable wildlife behavior, and low-contrast indoor shooting with aplomb.

The User Interface & LCD Screen: Getting Your Settings Right

The interface can make or break your shooting experience.

Ricoh’s GR II features a fixed 3.0-inch LCD with 1,230k dots but no touchscreen. Menus are straightforward but require button navigation. The fixed screen limits versatility for shooting at high, low, or awkward angles.

Sony’s A7 III sports a 3-inch tilting touchscreen with 922k dots. The touchscreen supports handy touch-to-focus and intuitive menu navigation suited for quick improvisation on shoots. The electronic viewfinder (EVF) in the A7 III is bright, high-resolution (2.36 million dots), with 100% coverage and 0.78x magnification, providing a rich framing experience in bright environments - a feature the GR II lacks unless paired with an optional optical viewfinder.

Lens Systems & Compatibility: Fixed vs Expandable

Lens variety can shape the scope of your photography dramatically.

The Ricoh GR II’s lens is fixed: a sharp 28mm f/2.8 prime lens. Despite the fixed focal length, the lens is optimized for street and landscape - fast enough for many daylight scenarios, with close-focus capability down to 10cm for basic macro shots. The lack of zoom or prime lens interchange is a limitation for broader creative control.

The Sony A7 III, on the other hand, uses the Sony E-mount compatible with over 120 native lenses from Sony and third-party manufacturers like Sigma and Tamron. This extensive ecosystem includes telephoto zooms, ultra-wide angles, macros, primes with f/1.4 apertures, and more - catering to virtually every genre from wildlife to architecture.
