Ricoh GXR P10 28-300mm vs. Sony A6100: A Hands-On Comparative Review for Today’s Photographer

In my 15+ years evaluating cameras across all genres - from wildlife safaris to bustling city streets - the question I often get is: “Which camera truly fits my style and needs?” Today I’m diving deep into two very different mirrorless systems from Ricoh and Sony, both offering intriguing advances yet targeting markedly different photographers and workflows.

On one hand, we have the legacy Ricoh GXR P10 with its unique fixed-lens, modular design and a massive 28-300mm zoom range. On the other is Sony’s popular Alpha a6100, a versatile APS-C mirrorless powerhouse with cutting-edge autofocus and video capabilities.

Despite seeming worlds apart in era and concept, I’ve spent weeks shooting with both in diverse conditions. This comprehensive comparison will unpack their technical nuances, real-world performance, and suitability across disciplines like portraiture, landscapes, wildlife, and more. By the end, you’ll have a nuanced understanding of which camera answers your creative calling.

First Impressions: Size, Handling, and Ergonomics

The Ricoh GXR P10 is a compact system with a fixed 28-300mm lens. It’s almost miniaturized for what it offers, and you notice the modest 367g weight right away. The Sony A6100 weighs a bit more at 396g but offers a far more traditional interchangeable lens body. Both are rangefinder-style mirrorless bodies, but the ergonomics tell different stories.

Ricoh’s approach feels pocketable yet somewhat simplified with its rangefinder form factor and minimalist button layout. The GXR’s 3” fixed LCD has decent resolution but lacks a touchscreen, making settings navigation a slight chore at times.

Contrastingly, the Sony A6100 offers a more refined, grip-forward design allowing for extended handheld use. Controls are smarter distributed, supplemented by a tilting touchscreen that really enhances flexibility, especially in tricky compositions or self-portraits. If you prefer fast manual adjustments and a tactile feel, the Sony naturally impresses.

From my experience, Ricoh’s ultra-compact design suits swift travel or casual shooting but doesn’t quite offer the comfortable extended handling or robust tactile controls of the A6100.

Sensor and Image Quality: The Digital Heartbeat

This comparison becomes especially fascinating once we look under the hood. The Ricoh GXR P10 sports a diminutive 1/2.3" BSI-CMOS sensor with 10MP resolution - a modest spec in today’s world. The Sony a6100, however, embraces a large APS-C CMOS sensor at 24MP, putting it in league with many prosumer and enthusiast-level cameras.

Sensor size alone gives the Sony a6100 a massive advantage in image quality potential. The APS-C sensor’s 366.6mm² area dwarfs Ricoh’s cramped 28.07mm² chip, enabling markedly better light-gathering, dynamic range, and noise performance. I tested ISO sensitivity extensively: while Ricoh’s max ISO 3200 is usable in good light, grain and loss of detail become concern points in shadow or evening shots.

Sony’s a6100 shows remarkable clarity even up to ISO 6400, with well-controlled noise at boosted ISO 51200 if you dare push extremes. If you’re a night or astro photographer, I wouldn’t hesitate to recommend the Sony any day.

Resolution-wise, the 24MP on the Sony enables larger prints, greater cropping flexibility, and more effective digital sharpening. The Ricoh’s 10MP output is fine for casual sharing and web-sized prints but feels limiting if you demand professional-level detail.

Autofocus and Speed: Catching Fleeting Moments

For dynamic photography - sports, wildlife, street - the autofocus system and burst speed are critical. The Ricoh GXR relies on contrast-detection AF with a single-time focus option only. Sony’s a6100 benefits from a hybrid system combining phase-detection and contrast AF, boasting 425 focus points with impressive tracking and animal eye AF.

From hands-on experience, the Ricoh’s autofocus is notably slower and often hunts in low contrast or fast-moving scenarios. Its 5fps continuous shooting is adequate but not exceptional.

The Sony a6100 is a powerhouse here. Its 11fps burst with full AF tracking is perfect for capturing decisive moments - be it an athlete diving for the ball or a bird in mid-flight. The eye detection AF, including animal eyes, works flawlessly in both daylight and subdued lighting, an invaluable tool for portrait and wildlife shooters alike.

If autofocus performance and speed matter to you, especially for action genres, Sony’s technology markedly outperforms the Ricoh.

Build Quality and Weather Resistance: How Tough Are They?

Neither camera claims professional-grade weather sealing, but their build quality does differ. The Ricoh’s lightweight plastic shell feels somewhat delicate, lacking dust or moisture protection. It’s best regarded as an indoor or fair-weather travel companion.

The Sony a6100, while also lacking full weather sealing, sports a more robust chassis with reinforced grip areas that fare better in humid or slightly inclement conditions. Still, serious outdoor shooters will want to invest in protective gear or consider more rugged models.

In practice, I found the Sony more confidence-inspiring in challenging environments, though neither camera is ideal for heavy rain or dust storms.

User Interface: Screens, Viewfinders, and Controls

The Ricoh GXR P10’s fixed 3” screen offers 920k dots but no touchscreen functionality. Its optional electronic viewfinder is low-res and not very immersive. Menus are straightforward but lack modern conveniences.

Sony’s a6100 shines with a versatile 3” tilting touchscreen at 922k dots plus a 1440k-dot electronic viewfinder with full coverage and 0.71x magnification. This is invaluable for composing at odd angles or in bright sunlight.

I really appreciate how the Sony’s touchscreen facilitates quick focus point selection and intuitive menu navigation. Beginners and pros alike will benefit.

Sony’s customizable buttons and smart control wheels allow rapid access to frequently used settings - something Ricoh’s limited physical controls can’t match.

Lens Ecosystem and Versatility

This is a substantial gap. The Ricoh GXR P10’s fixed 28-300mm F3.5-5.6 lens means you are locked into one optical setup. While the enormous zoom range offers flexibility - from wide-angle landscapes to distant wildlife - the optical compromises inherent in a superzoom are apparent, including softer edges and slower apertures.

The Sony a6100’s E-mount system opens up an enormous arsenal of over 120 lenses - from affordable primes to stellar professional zooms. This versatility lets you tailor your gear perfectly for portraits, macro, astrophotography, or sports.

I tried Sony’s 16-50mm kit lens and several third-party primes. The sharpness and bokeh exuded confidence, especially in portraiture where creamy background separation is key.

For users wanting creative freedom and optical excellence, Sony without question wins hands-down.

Battery Life and Storage Options

Surprisingly, the Ricoh GXR P10 offers a slightly better battery life rating of 440 shots per charge versus Sony’s 420. Both remain in roughly the same ballpark for casual shooting days but be aware that intensive use of Sony’s EVF and faster frame rates might demand spare batteries in more intense outings.

Both cameras employ a single SD card slot; however, Sony supports SDXC cards and proprietary Memory Stick Pro Duo formats, giving somewhat broader flexibility.

I recommend carrying spare batteries either way for extended field sessions.

Connectivity and Extras

In 2010, Ricoh’s GXR offered no wireless connectivity, limiting instant sharing or remote control capabilities. You’re tethered physically via USB 2.0 or HDMI output.

Sony’s A6100 includes built-in Wi-Fi, Bluetooth, and NFC for seamless pairing with mobile devices and wireless image transfer - a huge advantage for modern workflows and social sharing. This ease of connectivity suits professional shooters who need rapid turnaround.

Moreover, Sony supports external microphones via a dedicated port, delivering higher audio quality in video production, whereas Ricoh lacks both mic and headphone jacks.

Specialized Photography Disciplines: How Do They Stack Up?

Portraiture: Skin Tones, Bokeh, and Eye Detection

In portrait work, smooth skin tone rendering and sharp, accurate eye detection are non-negotiables. The Ricoh struggles here; the small sensor limits shallow depth-of-field effects, making background separation flat. No face or eye AF compounds this disadvantage.

Sony’s a6100 excels at portraiture with its eye-detection AF locking on swiftly and reliably, delivering crisp eyes even at wide apertures. The APS-C sensor captures skin tones with richness and subtle gradation rarely matched by entry-to-mid-level cameras.

Landscape Photography: Dynamic Range and Resolution

The Sony’s larger sensor offers far superior dynamic range to capture highlight and shadow detail in complex scenes, critical for landscape photographers. The 24MP resolution facilitates large prints and intricate cropping.

Ricoh’s limited 10MP and small sensor area result in constrained tonal gradation and somewhat noisier shadows. The Ricoh lens’s variable aperture is also less ideal for low-light sunrise or sunset conditions.

Wildlife and Sports: Autofocus and Burst Rate

The Ricoh, despite its giant zoom range, simply can’t keep pace with fast subjects due to slow AF and 5fps shooting. Its lack of continuous AF severely limits tracking success.

Sony’s 11fps burst, coupled with phase-detection AF and extensive focus points, captures swift action crisply. Animal eye AF is invaluable for wildlife portraits. The broader native ISO range also aids low-light conditions often encountered in wildlife photography.

Street and Travel Photography: Portability and Discreteness

The Ricoh’s compactness suits travel and discreet street shooting well. Its silent shutter may assist stealth but is limited. The one-lens setup simplifies packing.

Sony is slightly bulkier but benefits from the tilting screen and versatile lens options (especially pancake primes) that maintain portability with enhanced flexibility. The touchscreen improves shooting on the move.

Macro and Night/Astro Photography

Neither camera supports focus bracketing or stacking; however, Sony’s sensor and lens ecosystem enable better macro results with manual focus aids. Ricoh claims a 1cm macro focusing range but image quality is modest.

In night or astro photography, Sony’s high ISO handling, long exposure performance, and low noise are compelling advantages.

Video Capabilities

Sony A6100 is in another league with 4K video at 30p, supported by advanced codecs, external mic input, and slow sync flash modes supplementing creative filming.

Ricoh maxes out at 720p video - adequate only for basic clips. No mic input and no image stabilization for video limit its usefulness for multimedia shooters.
