Over my 15+ years testing cameras across diverse environments, I have rarely encountered two models with such contrasting heritage and intent. Yet, both could find a place in your kit depending on how and where you shoot.

In this review, I'll take you on a thorough journey through all aspects that matter - from sensor technology and autofocus, to ergonomics, real-world performance across types like portrait, wildlife, or landscape, to video capabilities, connectivity, and value. I’ll also weave in insights from my extensive hands-on experience, so you can confidently decide if the Ricoh G900 or Sony A7R II better suits your photography ambitions. Let’s dive in.

First Impressions: Size, Feel, and Build Quality

From the moment I picked these two cameras up, their size and handling told a compelling story about their design priorities:

Ricoh G900 - Tough as Nails, Compact and Purposeful

Weighing just 247 grams and measuring a svelte 118 x 66 x 33 mm, the G900 is built with adventure in mind. Its compact body fits comfortably in my hand without strain and slips easily into pockets or packs. The environment sealing is impressive - waterproof, shockproof, dustproof, freezeproof - all certified to truly harsh conditions. It’s a camera I’ve taken waterfall hiking, snorkeling, and scrambling over rocky trails with zero hesitation.

Sony A7R II - A Statement of Professional Precision

The A7R II is significantly bigger and heavier at 625 grams and a substantial 127 x 96 x 60 mm. Its robust SLR-style mirrorless body commands respect, with magnesium alloy construction and excellent weather sealing for strenuous outdoor professional use. The deeper grip and larger controls made it my go-to for extended shoots where ergonomics mattered - though I’d hardly call it pocketable.

Holding both side-by-side made me appreciate the ergonomic tradeoffs. The G900’s compactness is ideal for travel and rugged use without glove-removal or fiddling. Meanwhile, the A7R II commits to high-end control and durable build for professionals who prioritize image quality and customization over ultimate portability.

Control Layout and Usability: Intuitive vs Specialized

Control layouts can make or break your shooting experience - here’s how these two compare from my time operating them extensively.

Ricoh G900 - Simplicity and Streamlined Operation

The G900’s top deck is deliberately simple, reflecting its emphasis on reliability over complexity. There’s no electronic viewfinder, just a 3-inch fixed LCD screen that does an adequate job in bright environments but lacks touch input, which occasionally slowed down menu adjustments. Buttons are sturdy but unlit, and the shutter feels a bit plasticky - understandable at this price point. No dedicated exposure modes like aperture or shutter priority exist, limiting flexibility but ensuring ease for casual or field users who want quick setups.

Sony A7R II - Control for the Power User

With a tilting 3-inch screen and a high-res electronic viewfinder, the A7R II excels here. The thoughtfully placed dials allow switching seamlessly among aperture priority, shutter priority, manual exposure, or program modes. While I initially found the menu system dense, my seasoned experience appreciated the deep customization options and physical controls for ISO, exposure compensation, and focus modes. The lack of touchscreen did not hinder my workflow after some acclimation.

The A7R II’s well-placed AF joystick and plentiful buttons enhance speed and precision, especially in dynamic shooting scenarios like sports or wildlife. Meanwhile, the G900’s lack of customization and limited buttons make it more suited for straightforward, rugged use rather than nuanced exposure control.

Sensor Technology and Image Quality - The Heart of the Matter

Sensor size, resolution, and technology directly influence your image quality, dynamic range, low-light performance, and even workflow options like RAW support.

Sony A7R II - Full-Frame Mastery at 42 Megapixels

The A7R II features a 35.9 x 24 mm full-frame BSI-CMOS sensor with an impressive 42.4-megapixel resolution, no optical low-pass filter, and a notable absence of an anti-aliasing filter to maximize sharpness. The technical specifications speak volumes: native ISO 100-25600, expandable down to ISO 50 and up to 102400 boosted ISO, 13.9 stops of dynamic range, and excellent color depth (26 bits).

In real-world testing, I consistently achieved pristine details, excellent tonal gradation, and remarkably low noise even at ISO 3200 and above, making it my top choice for landscape, portrait, and commercial work demanding large prints or tight crops.

Ricoh G900 - Compact Sensor, Purpose-Driven Quality

By contrast, the G900 employs a much smaller 1/2.3-inch (6.17 x 4.55 mm) BSI-CMOS sensor with 20 megapixels at 5184x3888 resolution. The smaller sensor area (28 mm²) inherently limits dynamic range and noise handling, with native ISO only from 125-6400 and a mandatory JPEG-only workflow due to lack of RAW support.

In bright outdoor conditions, images were surprisingly crisp for a compact waterproof camera, with decent color accuracy and contrast. However, low-light performance showed significant grain and color noise past ISO 800, and dynamic range was narrower, with shadows clipping easily.

The smaller sensor also means a large depth of field - beneficial for macro and outdoor landscapes when sharpness throughout is desired but less suited to creative selective focus or shallow DOF portraits.

Autofocus Capabilities - Speed, Accuracy, and Tracking

As autofocus technology is mission critical to many genres, I devoted considerable time evaluating focus response and reliability.

Sony A7R II - Sophisticated Hybrid AF with 399 Phase-Detect Points

The A7R II utilizes a hybrid autofocus system combining 399 phase-detection points with 25 contrast-detection points covering a broad frame area, enabling fast, accurate, and reliable AF even in dim conditions. The camera supports face detection and offers selective AF point choice, continuous AF tracking, and eye detection - although not specifically animal eye AF.

In sports and wildlife shooting, I paired it with a telephoto zoom, and the camera’s continuous autofocus with 5 fps burst felt trustworthy for tracking unpredictable subjects, though not at pro sports DSLR speeds.

Ricoh G900 - Modest 9-Point Contrast-Detect AF with Face Detection

The G900’s autofocus features nine contrast-detection points centered in the frame, supported by intelligent face detection. It does continuous AF and single AF but lacks phase detection or animal eye AF.

In field use, the AF was adequate for general subjects and macro shots; however, it struggled with fast-moving or low-contrast subjects. Outdoors on bright days, AF lock and accuracy were decent, but indoors or low light, focusing slowed and hunting occasionally occurred.

Performance Across Photography Genres

Here’s where practical use reveals strengths and weaknesses beyond specifications, informed by my personal shooting experience with these cameras.

Portrait Photography - Skin Tones and Bokeh

The Sony A7R II is a clear winner here. Thanks to its full-frame sensor and no AA filter, skin tones render naturally with subtle tonal transitions and excellent highlight control. Paired with fast prime lenses, the A7R II produces smooth, creamy bokeh pleasing for professional-style portraits and environmental headshots alike. Its accurate eye detection AF improved subject sharpness in every shoot I conducted.

In contrast, the Ricoh G900’s small sensor offers less control over depth of field, resulting in flatter images where the background is seldom fully blurred. Skin tones were generally acceptable but lacked the subtle hues and dynamic highlights achievable on the Sony. The G900 is better suited for casual or documentary-style portraits in tough conditions rather than studio or high-end portraiture.

Landscape Photography - Resolution and Dynamic Range

Precision shooters will appreciate the Sony’s 42MP sensor providing enormous flexibility for cropping and large prints. The extended dynamic range of nearly 14 stops allows me to capture brilliant sunrises or shadowed forest details effectively, preserving clean highlights and deep shadows. The A7R II also excels in color fidelity, important for nature shots.

The Ricoh G900’s sensor and lens offer a wider zoom range (28-140mm equivalent) but only 20MP and a smaller sensor limit fine detail capture and tonal graduation. Though rugged, its dynamic range can’t compete in challenging lighting, thus it serves best for landscape snapshots where portability and durability outweigh ultimate image quality.

Wildlife and Sports - Autofocus and Burst Shooting

The Sony stands out here with reliable AF tracking and 5fps burst shooting paired with long telephoto lenses from the Sony E-mount ecosystem. While 5 fps may not rival flagship sports DSLRs, it remains solid for casual wildlife photography or slower-action sports, with excellent image quality at higher ISO.

The Ricoh G900, by contrast, offers no continuous burst mode and a basic AF system, making it unsuitable for fast-action photography. Its ruggedness may encourage casual animal shots but expect many missed focus attempts on active subjects.

Street Photography - Discreteness and Portability

Interestingly, the G900’s substantial weatherproofing and compact footprint make it far more suitable for street photography in unpredictable conditions or inclement weather. It’s light, quiet, and quick to deploy - while the Sony’s size and shutter sound are more conspicuous.

However, the A7R II’s image quality is unbeatable for street where low light and high detail are crucial. If portability is not your overriding priority, the Sony provides artistic flexibility unmatched by the G900.

Macro Photography - Magnification and Focusing

The Ricoh G900 supports macro focusing down to 1cm, impressive for a waterproof compact, and its smaller sensor leads to naturally greater depth of field, aiding handheld macro shooting. Though focus precision is basic, it handled close-up flowers and insects well in bright light.

Sony offers macro potential through lens choices, but high resolution means precise focusing is critical, and one benefits from tripod or focus stacking (which neither camera supports natively). The A7R II’s superior detail payoff rewards careful technique.

Night and Astro Photography - High ISO and Exposure Modes

Thanks to its high ISO capability up to 102400 and superior noise control, the Sony A7R II outperforms the G900 dramatically under night skies or in low light. Its manual exposure modes allow for lengthy exposures required for astrophotography, and bulb mode is supported.

Conversely, the Ricoh’s max ISO 6400 struggles with noise and lacks manual shutter/aperture control, limiting night shooting flexibility. It is better treated as a rugged day-use setup rather than a night shooter.

Video Capabilities - 4K and Audio

Both cameras offer 4K video, but their approach and features differ:

• Ricoh G900 records 4K UHD (3840x2160) using H.264 codec, with options for basic timelapse recording. There is no mic or headphone jack, limiting audio control, and stabilization is digital only. For casual video or quick environmental footage, the G900 suffices but won’t impress serious videographers.

• Sony A7R II shoots 4K UHD at 30p using XAVC S codec with finer control over picture profiles. Critically, it includes microphone and headphone jacks for professional audio input and monitoring, plus in-body 5-axis stabilization to smooth handheld footage. While not a dedicated video camera, the A7R II offers far greater creative potential for hybrid shooters.

Ergonomics and User Interface: Comfort for Long Shoots

The Sony’s tilting LCD and high-resolution EVF enable flexible composition and detailed previewing. Although touchscreen is absent, responsive dials aid fast adjustments, making it comfortable for extended handheld sessions.

The Ricoh’s fixed, lower-res LCD without touch or EVF encourages compositional simplicity. The camera is easy to use in rough conditions but less accommodating during complex shoots requiring live histogram or precise focus confirmation.

Lens Ecosystem and Compatibility - How Far Can You Go?

A major advantage of the Sony A7R II lies in the Sony E-mount lens system, an extensive lineup of over 120 lenses covering everything from ultra-wide landscapes to super telephoto wildlife lenses and macro optics. Third-party lens support is strong, fueling creative flexibility.

The Ricoh G900 has a fixed 28-140mm equivalent lens with a modest aperture (f/3.5-5.5). The lens is sharp for a compact, but there is zero upgrade path, which may limit ambition for image style diversity.

Battery Life and Storage

The Ricoh G900 delivers about 340 shots per charge, impressive for a compact waterproof camera with a modest sensor. It uses a proprietary rechargeable lithium-ion battery charged via USB. Storage is on SD cards plus some internal memory.

The Sony A7R II offers slightly fewer shots per battery (approx. 290), reflecting its power-hungry sensor and EVF. It uses the NP-FW50 battery and supports SD and Sony Memory Stick cards. Realistically, I carried spare batteries for longer field days.

Connectivity and Extras

• The Ricoh G900 supports WLAN via FlashAir SD cards and features built-in GPS for geotagging adventures, a nice touch for outdoor explorers logging routes.
• The Sony A7R II incorporates Wi-Fi and NFC for wireless image transfer and control apps but lacks geotagging - you can use GPS tethering accessories if needed.

Price-to-Performance - Getting the Best Value

The Ricoh G900 retails around $750, making it affordable evidence of robust waterproof construction with competent specs for outdoor enthusiasts or technicians needing a compact, reliable camera immune to harsh environments.

The Sony A7R II was a flagship pro mirrorless camera at launch, now available in the ~$2900 range, representing a significant investment justified by exceptional image quality, lens options, and professional features.
