When considering advanced mirrorless and large-sensor superzoom cameras, the Ricoh GXR P10 28-300mm F3.5-5.6 VC and the Sony Cyber-shot DSC-RX10 stand out as intriguing options for different reasons. Though announced four years apart, these cameras appeal to serious enthusiasts and professionals seeking versatile zoom reach and solid imaging performance without the complexity of interchangeable lenses. I’ve extensively tested both in varied shooting scenarios across portrait, landscape, wildlife, and beyond to give you an authoritative, hands-on comparison that clarifies which may suit your needs.

First Impressions and Ergonomics: Handling Matters

At first glance, the Ricoh GXR P10 is notably compact and lightweight at just 367 grams and dimensions of 114 x 58 x 50 mm, embodying a sleek, rangefinder-style mirrorless form factor. Conversely, the Sony RX10 opts for a more substantial, SLR-like body tailored for robust handling - weighing 813 grams with a chunkier 129 x 88 x 102 mm build. This size difference immediately signals contrasting design priorities: portability vs. grip and control.

The RX10 impresses with a top plate featuring dedicated dials for exposure, shutter speed, and aperture, catering to photographers who value quick manual adjustments on the fly. The Ricoh, while simpler, offers essential controls but with fewer physical dials, requiring more menu interaction. I found the RX10 ergonomics ideal for long shoots where tactile control reduces the need to look away from the viewfinder–a big win in fast-paced environments like sports or wildlife.

If you prize pocketability and quick grab-and-go usability, Ricoh’s GXR P10 feels nimble and discreet. However, for extended sessions and precision adjustments, the RX10’s comfortable heft and button layout provide a more professional experience.

Sensor Technology and Image Quality: Size and Resolution Speak Volumes

A camera’s sensor directly influences image detail, noise performance, and dynamic range. The Ricoh GXR P10 operates with a 1/2.3” BSI-CMOS sensor sized 6.17 x 4.55 mm (28.07 mm²) at 10 megapixels. Its sensor size is fairly small, reflective of compact fixed-lens cameras but limiting in image quality potential, especially in low light.

The Sony RX10 boasts a much larger 1” BSI-CMOS sensor, measuring 13.2 x 8.8 mm (116.16 mm²) at 20 megapixels - over four times the surface area of Ricoh’s. This is a critical advantage since a larger sensor gathers more light, yielding better color depth, dynamic range, and lower noise at higher ISO.

In technical tests and real-world shooting, the RX10 delivers noticeably cleaner images at ISO 800 and beyond, preserving details and producing richer colors. The Ricoh performs adequately at base ISO800 and lower but exhibits noise intrusion and softer detail as ISO climbs to 1600 and 3200, which is its max native ISO. Highlight retention and shadow recovery are also superior on the RX10, capturing a broader tonal range in high-contrast scenes like landscapes or backlit portraits.

Color depth measured via DxO benchmarks (while Ricoh lacks official scores) clearly places the RX10 well ahead, with a rating of 22.9 bits versus typical small-sensor performance. This difference shapes the image quality gap, making RX10 images more suitable for large prints and professional use.

Autofocus and Shooting Performance: Speed, Accuracy, and Tracking

Autofocus (AF) is crucial, especially when hunting wildlife, sports, or moment-driven street photography. The Ricoh GXR uses a contrast-detection AF system with single AF mode only, no continuous or tracking capabilities, and no face or eye detection. Focus speed is noticeably slower, requiring patience in low light or with moving subjects, which I found limiting in fast-action scenarios.

The Sony RX10 integrates a more advanced contrast-detection AF with 25 focus points across center and multi-area modes, including face detection. Continuous AF shooting at 10 fps makes it significantly more capable for capturing fast-moving subjects and dynamic scenes. While not boasting phase detection, Sony’s Bionz X processor helps optimize AF responsiveness.

In practice, RX10’s AF tracked subjects with gratifying precision, handling wildlife movements or sports players better. Ricoh’s slower focusing is manageable for casual or landscape shooting but frustratingly sluggish where speed counts.

Lens and Zoom Capabilities: Reach, Brightness, and Versatility

Both cameras feature fixed zoom lenses, but their ranges and apertures differ notably:

• Ricoh GXR P10: 28–300mm equivalent focal length with variable aperture F3.5–5.6
• Sony RX10: 24–200mm equivalent with a constant bright aperture of F2.8

The Ricoh’s impressive 10.7x zoom gives versatility reaching into telephoto territory ideal for distant wildlife or detail shots, but the maximum aperture narrows considerably at longer focal lengths, reducing light intake and depth of field control.

Sony offers a slightly shorter zoom range (8.3x), yet its constant F2.8 aperture affords superior low-light performance and creamy bokeh throughout the zoom. This results in better subject separation and noise management in dim conditions while shooting portraits or events.

Stabilization-wise, Ricoh relies on sensor-shift image stabilization (IS), effective mainly for handheld long exposures but less impactful for video. Sony’s lens-based Optical SteadyShot IS is highly efficient, noticeably reducing handshake blur and enhancing video smoothness.

Display and Viewfinder: Composition and Usability

Display and viewfinder design impact your ability to compose accurately across lighting conditions:

Ricoh GXR P10 offers a fixed 3-inch LCD with modest 920k-dot resolution, sufficient for casual framing but less crisp. Its lack of a built-in electronic viewfinder (EVF) means relying on the rear screen, limiting usability in bright sun or steady hold.

The Sony RX10 excels here with a higher-resolution 3-inch tilting WhiteMagic LCD displaying 1.29 million dots, providing excellent clarity and flexible angles for creative compositions. It also includes a high-res EVF with 0.7x magnification and 100% coverage, a critical advantage for eye-level shooting, especially in sunlight or fast-moving scenarios.

In my field tests, the RX10’s EVF greatly improved accurate framing and made manual focus easier, whereas the Ricoh’s absence of an EVF was inconvenient outdoors or for detailed focusing tasks.

Video Features: Capabilities and Limitations

For enthusiasts dabbling in video or hybrid use, these cameras differ substantially:

• Ricoh GXR P10 records up to 720p at 30fps in Motion JPEG format - adequate for casual clips but lacking in quality or frame rate options.
• Sony RX10 supports full HD 1080p recording at 60fps, 60i, and 24fps in efficient MPEG-4 and AVCHD formats, providing smooth motion and greater cinematic flexibility.

Sony also includes microphone and headphone jacks, enabling improved audio input/output control - a significant plus for serious videographers. Ricoh has no external audio ports and limited video format support; its video function feels more like a convenient add-on.

Image stabilization on the RX10 translates into steadier video hand-held footage, a crucial advantage for run-and-gun shooting.

Build Quality and Environmental Resistance

Neither camera is fully weather-sealed or freezeproof, but the Sony RX10 features some robust environmental sealing against moisture and dust, designed to endure harsher shooting conditions. Ricoh’s GXR P10, while solidly built, lacks any dedicated weather resistance, making it less suitable for inclement weather or heavy outdoor use.

Battery Life and Storage

Battery life is comparable:

• Ricoh GXR P10 rated for about 440 shots per charge
• Sony RX10 for approximately 420 shots per charge

In practical use, both deliver dependable stamina for a day of shooting, but the RX10’s larger battery and power management offer a slight edge. Storage-wise, both share support for SD card formats, but Sony adds compatibility with Memory Sticks Pro Duo formats, offering more flexibility.
