When we pit the Ricoh WG-6, a rugged waterproof compact, against the Sony A99, a full-frame advanced DSLR from a previous decade, it’s clear this is a clash not of mere models but of camera philosophies. While their specs and target users couldn’t be more different, exploring their strengths and weaknesses side-by-side yields valuable insights for enthusiasts contemplating what kind of tool best suits their photography journey.
Over years of reviewing thousands of cameras, I’ve learned that the camera you choose is less about absolute specs and more about how those specs translate into images in real-world use across genres. So let’s unpack these two with a focus on practical performance, handling, image quality, and versatility from the streets and landscapes to wildlife and video. Along the way, I’ll share nuggets from hands-on testing and what each camera means for different user profiles.
A Study in Size and Handling: Compact Ruggedness Meets DSLR Bulk
Our first impression always starts in the hand. The WG-6 is a compact marvel, measuring just 118 x 66 x 33 mm and weighing a mere 246 g, designed to slip into a jacket pocket or glove compartment without fuss. By contrast, the Sony A99 stands imposing at 147 x 111 x 78 mm and tipping the scales at 812 g - truly a mid-size DSLR with heft and presence.

Ricoh’s WG-6 clearly favors portability and durability. Its sealed body is crafted for life underwater or in grimy, harsh environments, making it a perfect companion for adventure seekers or casual shooters unafraid to get their hands wet. It eschews an eye-level viewfinder for simplicity and ruggedness, relying solely on a fixed 3-inch LCD.
The Sony A99, on the other hand, rewards the photographer who prefers a firm, secure grip, extensive manual control, and an articulated screen for creative angles. The heft can be a burden for lengthy hikes but also signals solidity and balance when attached to long professional lenses - a benefit when shooting wildlife or sports.
Handling-wise, both cameras deliver tactile controls tuned to their audiences, but with completely different philosophies.
Control Layout and User Interface: Intuitive vs Comprehensive
Switching to the top view, the Ricoh WG-6 offers a minimalist design with essential buttons laid out for quick operation. Its non-touch capacitive LCD of modest 1040k resolution is fixed, limiting framing techniques but contributing to weather sealing integrity.
The Sony A99 boasts a more sophisticated control layout, with dedicated dials, an illuminated top screen, and a 1229k-resolution fully articulated TFT Xtra Fine LCD, balancing versatility with some complexity.

I appreciate that the WG-6 trims complexity, which benefits rugged usage where gloves or wet hands make fiddly controls frustrating. Sony’s A99 handles better when precision adjustments are frequent, with shutter speed, aperture, and exposure compensation all easily accessible - features that serious photographers expect for fast-paced shooting scenarios.
Beginners and compact camera lovers will feel at home with Ricoh’s straightforward design; advanced users will appreciate Sony’s extensive manual exposure modes and customizability.
Sensor Technology and Image Quality: Small Sensor vs Full Frame
This is where the biggest technical gulf reveals itself. The WG-6 houses a 1/2.3-inch BSI-CMOS sensor with 20 megapixels, whereas the A99 sports a 35.8 x 23.8 mm full-frame CMOS sensor at 24 megapixels.

The WG-6’s sensor, despite modern BSI (backside illuminated) architecture designed to improve light gathering, fundamentally limits image quality, especially in low light, dynamic range, and shallow-depth-of-field capabilities. Nikon adventures prove that tiny sensors can deliver crisp daylight snaps but falter under challenging conditions.
Conversely, the A99 balances a mature Bionz processor with full-frame sensor advantages - cleaner high ISO performance, a broader dynamic range (14 EV vs practically 7–8 EV on the compact), and more subtle color gradations. This translates into images with richer detail in shadows and highlights, significantly lower noise in dim conditions, and better bokeh control.
Ultimately, if image fidelity is your prime concern, especially for portraits or landscapes, the A99 is a clear winner. For snapshots, travel, or situations where durability beats image perfection, WG-6 suffices nicely.
Viewing and Framing Experience: LCD Only vs EVF Plus LCD
Neither the WG-6 nor the A99 offer the latest touchscreen capabilities, but their screens and viewfinders play very different roles.
The WG-6 relies on a fixed 3-inch LCD, adequate for casual framing and reviewing images but limited by its fixed angle and modest resolution, which can make fine focus checking challenging, especially in bright sunlight.
The A99 suits more deliberate compositions with a bright 2.36M-dot electronic viewfinder offering 100% coverage and 0.71x magnification, alongside a vari-angle 3-inch LCD. This combination allows framing in diverse situations: from eye-level precision focusing via the EVF to creative low or high-angle shoots with the articulated screen.

From field testing, when tracking fast-moving subjects or in street scenarios, the EVF drastically improves stability and confidence in framing - a huge advantage absent on Ricoh’s compact.
Autofocus and Burst Shooting: Basic Tracking vs Professional Tracking
Autofocus is a crucial performance domain. Ricoh’s WG-6 provides 9 contrast-detection AF points with face detection, continuous and single AF modes, and basic tracking. This system works reliably in well-lit, straightforward scenes but is limited by the sensor and processor speed.
Sony’s A99 employs a hybrid phase-detection and contrast-detection system with 19 AF points (11 cross-type), selective AF modes, eye detection, and more sophisticated AI tracking. The camera’s burst rate clocks in at 10 fps, making it significantly more capable for action photography.
In real-world tests - wildlife, sports, and fast-moving street scenes - the A99’s autofocus proved faster, more responsive, and stayed locked on heads or eyes with fewer misfires. The WG-6’s system is passable for casual use but lags in consistently nailing focus on erratic or distant subjects.
Lens Ecosystem and Telephoto Coverage: Fixed Lens vs Interchangeable
The WG-6 sports a 5x zoom equivalent to 28–140mm F3.5–5.5, a versatile range for day trips and general scenes but a fixed lens that limits creative flexibility or reach for wildlife photography.
Contrast that with Sony’s Alpha mount supporting 143 lenses ranging from ultra-wide zooms to super telephotos and expert primes. This lens ecosystem enables A99 users to tailor setups precisely - whether macro, portrait, sports, or astrophotography.
This also influences image quality since pro-grade lenses can extract the sensor’s full potential, while fixed lenses in compacts often sacrifice sharpness or suffer distortion.
Build Quality and Durability: Rugged Waterproof vs Sealed Pro Body
This one’s easy: the WG-6 is waterproof to 20 meters, shockproof from 2m, crushproof, freezeproof - essentially built for abuse. It is the outdoorsman or traveler's trusted comrade when conditions demand hardiness over sensitivity.
The Sony A99 is weather-sealed against dust and moisture but not waterproof or shockproof. It offers robust magnesium alloy construction befitting a pro DSLR but requires careful handling in adverse weather and rough terrain.
So, for underwater boating, mountain biking, or even casual pool photography, WG-6’s durability is unmatched in this comparison.
Battery Life and Storage: Compact Efficiency vs Extended Capacity
On paper, Ricoh’s WG-6 offers around 340 shots per charge, impressive given its size and power constraints. Its single SD card slot stores images, which are only JPEGs due to lack of RAW support.
Sony’s A99 uses the larger NP-FM500H battery, rated for a hefty 500 shots - useful for longer shoots, especially with the added power draw of phase-detection AF and bigger sensors. Dual card slots support Memory Stick and SD cards, enabling overflow or backup recording and RAW capture for ultimate image control.
Connectivity and Extras: Modest Wireless vs Limited
Ricoh supports Toshiba’s FlashAir wireless SD cards for basic image transfer but lacks Bluetooth or NFC. It includes built-in GPS useful for travel snapshots.
Sony’s A99, from an earlier era, has no wireless features, reflecting pre-WiFi mainstream designs, but offers mic and headphone ports - favoring videographers - plus HDMI out.
Video Features: 4K Outdoors vs Full HD Studio
The WG-6 surprises at this price point with 4K UHD video at 30fps, which is neat for quick handheld footage. However, digital image stabilization (rather than optical) and no mic port limit sound and shake control.
Sony’s A99 offers up to 1080p HD at 60 fps with advanced AVCHD codecs and external mic/headphone jacks - clearly designed to accommodate more serious video work albeit without modern 4K. The fully articulated screen also aids movie shooting flexibility.
Real-World Performance by Photography Genre
To better contextualize strengths, let’s review how each camera fares in key photographic disciplines:
Portraits:
The A99’s larger sensor captures skin tones with subtlety and accurate exposure; beautiful creamy bokeh from fast primes enhances subject separation. Its eye detection keeps focus sharp on faces - a distinct edge.
WG-6’s small sensor and fixed lens produce flatter portraits with less background blur and lower dynamic range. Face detection helps casual snaps but won’t yield professional results.
Landscapes:
Sony’s high resolution and 14 stops dynamic range preserve detail in skies and shadows. Weather sealing and a rich lens ecosystem enable wide-angle landscapes with exquisite clarity.
Ricoh works for travel landscapes on a budget, especially with waterproof protection, but image quality is limited by noise and compressed tonal gradations.
Wildlife:
A99 shines with fast phase-detect autofocus, 10 fps burst, and telephoto lens reach, capturing fast birds or mammals in native resolution.
WG-6’s zoom and AF lag make it ill-suited for wildlife beyond casual observing or snorkeling shots.
Sports:
Again, Sony dominates with tracking AF and frame rate, crucial for fast-moving athletes.
WG-6 keeps up only at slow-paced activities or snapshots.
Street:
WG-6’s compactness, durability, and discreet size benefit street shooters who want to travel light and shoot on the fly.
Sony’s size and shutter noise are less stealthy but compensate with image quality and manual control for enthusiasts.
Macro:
WG-6 boasts a 1cm macro focus distance, making close-ups easy without accessories.
Sony can outperform if paired with dedicated macro lenses but requires investment.
Night/Astro:
A99’s high ISO performance and longer exposures handle low light or star fields well.
WG-6’s sensor noise and limited ISO ceiling hamper night shots.
Video:
WG-6 gives casual users 4K capture with stabilization but limited audio options.
A99 delivers full HD video with advanced audio inputs ideal for semi-pro video creation.
Travel:
WG-6’s ruggedness, GPS, and pocketable size make it travel-ready.
