In-Depth Comparison: Ricoh GXR P10 28-300mm F3.5-5.6 VC vs. Sony Cyber-shot DSC-RX1R II

In the evolving landscape of digital cameras, niche solutions frequently emerge that target fundamentally different types of photographers, despite surface-level similarities such as fixed-lens systems or compact formats. The Ricoh GXR P10 28-300mm and the Sony RX1R II exemplify this divergence. Both cameras eschew interchangeable lenses but diverge substantially in sensor technology, image quality ambitions, autofocus sophistication, and overall operational philosophy. This comprehensive comparison draws from extensive personal field testing and technical measurements to help experienced enthusiasts and professionals understand which system better suits varying photographic demands.

Design and Ergonomics: Compact Versus Retro Svelte

Both cameras adopt fixed-lens solutions, but their physicalities speak to radically different eras and target users.

The Ricoh GXR P10 is a rangefinder-style mirrorless system released in 2010, equipped with a super-telephoto zoom extending from 28mm to 300mm equivalent focal length with a variable F3.5–5.6 aperture. Its compact body measures approximately 114 × 58 × 50 mm and weighs a light 367 grams, emphasizing portability and lightweight construction. The fixed 3-inch LCD with 920k dots provides adequate viewing but lacks touchscreen functionality or an integrated electronic viewfinder.

By contrast, the Sony RX1R II, launched in 2015, is a "large sensor compact" with a classic, understated form factor reminiscent of high-end rangefinder cameras. Its dimensions (113 × 65 × 72 mm) and weight (507 grams) reflect a more robust build incorporating a full-frame sensor and advanced optics. Key ergonomic advantages include a tilting 3-inch screen with 1,229k dots resolution, an integrated high-resolution electronic viewfinder (EVF) with 2,359k dots and 100% coverage, and a refined control layout designed for rapid manual adjustments.

Testing revealed that while the Rosy GXR’s lightweight body ranks high on travel and street portability, it sacrifices grip security and intuitive manual control placement common in the RX1R II. The latter’s more substantial heft and ergonomic refinements cater better to longer handheld sessions, offering balanced handling when coupled with its fast 35mm f/2 prime lens.

Sensor and Image Quality: From Modest 1/2.3-inch to Full-Frame Excellence

A critical divergence lies in sensor architecture and resultant image quality. The Ricoh GXR P10 uses a 1/2.3-inch BSI-CMOS sensor with dimensions approximately 6.17 × 4.55 mm yielding a resolution of 10 megapixels (3648 × 2736 pixels). Though respectable for compact zoom cameras of the era, its sensor size equates to just 28.07 mm², limiting low-light performance and dynamic range.

The Sony RX1R II shocks this comparison by employing a 35.9 × 24 mm full-frame back-illuminated CMOS sensor with 42.4 megapixels (7952 × 5304 pixels). For reference, this sensor is roughly 30 times larger in surface area than the Ricoh’s, enabling vastly superior resolution retention, tonal gradations, and color depth.

Technical measurements from DxOMark affirm Sony’s supremacy: a color depth of 25.8 bits, dynamic range approximating 14 EV stops, and excellent high-ISO performance with native ISO up to 25600 (expandable to 102400). The Ricoh’s sensor lacks official testing but industry benchmarks for similarly sized sensors suggest significantly reduced image latitude and color fidelity.

In real-world conditions, the Sony’s sensor delivers clean, crisp images with rich shadow detail and highlight preservation, even at elevated ISOs. The Ricoh's smaller sensor, paired with a compressed 10 MP resolution, produces noticeably softer, noisier images when ISO exceeds 800.

Lens Performance and Optical Versatility

The Ricoh GXR P10 sports a stabilized zoom lens spanning a remarkable 28–300 mm equivalent range at F3.5–5.6 aperture, offering unmatched telephoto reach in a compact form. The lens utilizes sensor-shift stabilization, which though helpful, is often less effective at extreme focal lengths and slower apertures.

Conversely, the Sony RX1R II incorporates a fixed 35 mm f/2 prime lens renowned for exceptional sharpness and minimal distortion. This lens omits an optical low-pass filter to further enhance resolution. However, it lacks any built-in optical image stabilization.

This dichotomy frames a classic tradeoff: Ricoh prioritizes reach and flexibility at the cost of maximum aperture and resolving power, whereas Sony commits to optical excellence and speed within a moderate focal length.

During extensive use, the Ricoh lens exhibits average sharpness wide open and reasonable corner retention mid to telephoto, though it cannot match the microcontrast and edge acuity of Sony's renowned Zeiss-designed prime. The RX1R II lens excels in delivering high resolution across the frame, achieving excellent bokeh quality thanks to the f/2 aperture and well-controlled aberrations.

Autofocus Systems: Basic Contrast Detection Meets Hybridity

Autofocus implementation shapes how effectively these cameras negotiate a range of subjects, particularly moving ones.

The Ricoh GXR P10 relies solely on contrast-detection AF without face or eye detection. It supports only single-shot AF, lacking continuous AF modes, tracking, or selectable focus points. Consequently, it is best suited for static subjects and slower-paced compositions. The absence of AF area selection severely limits operational flexibility in candid or dynamic scenarios.

The Sony RX1R II employs a hybrid AF system combining phase detection and contrast detection across 25 AF points with multiple area options including selective, multi, center, face detection, and AF tracking. Eye AF is also incorporated for improved portrait accuracy. Although it does not offer continuous AF for video or burst, autofocus speed and precision in stills significantly outperform the Ricoh’s system.

In practical scenarios, the RX1R II focuses swiftly and accurately on static and moderately moving subjects, reliably locking on eyes for portraits - an uncommon advantage in compact full-frame cameras. The Ricoh’s AF struggles in low light and slower to acquire focus at longer focal lengths where telephoto sensitivity becomes critical.

Shooting Performance and Speed: Throughput Considerations

Regarding upper mechanical limits, both cameras offer continuous shooting at up to 5 frames per second, placing them nominally on par. However, buffer depths and autofocus limitations complicate actual throughput.

The Ricoh’s 10 MP files allow longer bursts before buffer saturation; however, the lack of continuous AF and tracking tools severely limits utility in sports or wildlife action. Additionally, shutter speed caps at 1/2000 second restrict freezing very fast motion or wide aperture usage in bright light.

The Sony enables shutter speeds up to 1/4000 second, beneficial for wide apertures in daylight and faster motion capture. It maintains consistent focus tracking within its capabilities during bursts, though buffer limitations come into play quickly on the large RAW files it produces. Electronic shutter options and silent shutter modes are unavailable in either system.

Viewfinders and LCD Interfaces: Critical User Experience Factors

Both cameras rely heavily on their rear LCDs for composition due to fixed lenses.

The Ricoh features a 3-inch fixed LCD with 920k-dot resolution, which is serviceable but somewhat dim and restrictive, lacking touch functionality or tilting articulation. Its optional electronic viewfinder is not integrated and was never a priority for the design.

The Sony’s approach incorporates a tilting 3-inch, 1.2 million-dot LCD combined with a bright, high-resolution EVF offering 100% coverage and 0.74x magnification for critical manual focusing and exposure control. The EVF elevates compositional confidence and visibility in bright outdoor conditions, where LCD glare often hampers usability.

Physically, the Sony’s button layout and dials provide tactile feedback with minimal menu diving, whereas Ricoh’s controls are more minimal and can appear clumsy in action-focused workflows.

Video Capabilities: Basic Versus Semi-Professional Support

Video functionality sharply contrasts between the two. The Ricoh GXR P10 offers only basic HD video at 1280x720 at 30 fps using Motion JPEG compression. No advanced features, no external mic input, and a limited codec severely restrict video quality and workflow integration.

The Sony RX1R II caters to enthusiasts needing more comprehensive video, delivering full HD 1080p at 60fps with better compression schemes (MPEG-4, AVCHD, XAVC-S) and slow-motion 720p at 120fps. Although it lacks 4K, its microphone input port enables improved audio capture, a critical asset for serious video shooters. It does not support headphone output or in-camera image stabilization during video.

Battery Life and Storage: Longevity and Capacity

The Ricoh offers longer battery life, rated at approximately 440 shots per charge, commendable given its low-power sensor and limited display functionality. It stores images on SD/SDHC cards or internal memory (limited capacity).

The Sony RX1R II, with its high-resolution sensor and EVF, sacrifices endurance to about 220 shots per charge. Users must plan accordingly or carry spare batteries, especially for extended sessions. The RX1R II offers support for SD, SDHC, SDXC cards, and proprietary Sony Memory Stick Pro Duo, increasing versatility.

Build Quality and Durability: Weather Resistance and Toughness

Neither camera has official environmental sealing, dust-proofing, or shockproof certifications. Both demand careful handling in adverse weather or rugged environments.

The RX1R II’s robust magnesium alloy body feels more authoritative and durable in hand, whereas the Ricoh leans towards lightness and convenience over ruggedness.

Connectivity and Wireless: Modern Conveniences Versus Legacy

The Ricoh GXR P10 completely lacks wireless connectivity; no Wi-Fi, Bluetooth, or NFC are available. This limits instant image sharing or remote shooting.

Sony’s RX1R II includes built-in Wi-Fi and NFC connectivity, allowing image transfer and smartphone remote control without physical cables. It also supports USB 2.0 and HDMI output.
