Choosing a camera often feels like walking into a labyrinth of specifications, jargon, and marketing hyperbole. After over 15 years of testing cameras across every genre - from wildlife safaris to studio portrait setups - I appreciate that the best choice always depends on your unique photographic priorities. Today, we’re going to dissect two cameras that couldn’t be more different in intent but might both fit into your kit depending on your shooting style: the rugged Ricoh WG-70, a tough waterproof compact built for adventure, versus the versatile Sony Alpha a6100, an advanced mirrorless camera aimed at enthusiasts seeking speed and image quality.

This extensive comparison draws on thorough hands-on evaluation, technical scrutiny, and real-world testing to clarify which camera suits which photographer best. We’ll cover everything from sensor tech, autofocus, ergonomics, to genre-specific performance and value - unpacking all you need to decide confidently.

Distinct Bodies, Distinct Purposes: Ergonomics and Handling

First impressions matter, and the Ricoh WG-70 and Sony A6100 visually and physically assert their different ambitions. The WG-70 is a tough, compact camera designed to withstand the elements - waterproof, dustproof, shockproof, freezeproof, and crushproof. By contrast, the Sony A6100 is an advanced mirrorless with an interchangeable lens system, favoring versatility and image quality over ruggedness.

The Ricoh WG-70’s compact 123x62x30 mm profile and featherweight 193g make it highly portable - it slips into a jacket pocket and is at home underwater or on dusty hikes without a care. The controls are straightforward, with large buttons and a textured grip that harks to “point-and-shoot simplicity,” crucial for quick operation while wearing gloves or in wet conditions.

The Sony A6100, larger at 120x67x59 mm and 396g body-only weight, offers a more substantial hand feel with a pronounced grip. It fits naturally in your palm for longer shoots, especially when mounted with lenses, which adds bulk but brings professional-grade handling ergonomics. The A6100 body provides more dedicated buttons, dials, and a customizable control interface tailored for photographers who want immediate access to settings.

Ergonomics takeaway: The WG-70 excels in portability and ruggedness for casual or outdoor-focused shooters, while the A6100’s refined controls and larger body suit enthusiasts and pros needing flexible handling and quick access under pressure.

Sensor and Image Quality: The Heart of the Camera

When I pull a camera off the shelf, the sensor and processing engine are my first stop for assessing potential image quality.

The Sony A6100 sports a sizeable APS-C CMOS sensor measuring 23.5x15.6 mm with a 24MP resolution, considerably larger than the WG-70’s tiny 1/2.3" (6.17x4.55 mm) BSI-CMOS sensor at 16MP. That difference in sensor area - 366.6 mm² versus 28.07 mm² - is crucial. Larger sensors capture more light, produce cleaner images at high ISO, and enable shallower depth of field for pronounced background blur - vital for portrait and creative work.

The WG-70's sensor, common in rugged compacts, is optimized for reliability rather than outright quality. Images from the WG-70 are acceptable at base ISO (125–400) but noise creeps in rapidly above ISO 800, and fine detail suffers due to smaller pixels and a fixed lens with moderate sharpness.

In terms of raw capability, the A6100 also supports RAW capture - giving post-processing latitude - where the WG-70 offers JPEG-only output, limiting flexibility.

Our lab tests and real-world shooting confirm the A6100’s superior dynamic range, more accurate color rendition, and cleaner shadows/noise balance. The WG-70 is a competent point-and-shoot for snapshots but struggles with complex lighting or demanding print sizes.

Viewing and Composing: Screens and Viewfinders

Effective composing tools are critical to speed and accuracy in photography. Here’s how the two tackle this.

The Ricoh WG-70’s smaller 2.7-inch fixed, non-touch screen has a meager 230k-dot resolution, making it challenging to judge fine focus or image details in bright sunlight. There’s no electronic viewfinder (EVF), so you’re limited to the rear LCD for framing.

Sony’s A6100 counters with a 3-inch tilting touchscreen boasting 922k dots - a significant upgrade. The touchscreen interface allows intuitive focus point selection and menu navigation, enhancing workflow speed. Additionally, the A6100 features a high-res electronic viewfinder (1.44M-dot, 0.71x magnification, 100% coverage), which provides a critical eye-level composing aid in bright conditions, acting much like an optical finder but with information overlays and real-time histogram.

For photographers shooting outdoors, landscapes, or street scenes, the A6100’s EVF is a game-changer - faster, more precise focusing with fewer stray reflections.

Autofocus: Speed, Precision, and Intelligence

Autofocus can make or break many shooting scenarios, particularly for active subjects.

The Ricoh WG-70 offers 9 autofocus points relying solely on contrast detection. While this system can lock focus accurately in good lighting, it’s noticeably slower and less reliable tracking moving subjects, which impacts sports or wildlife scenes. However, it does include face detection - helpful for casual portraits.

In contrast, the Sony A6100 uses a hybrid AF system combining 425 phase-detection points with contrast detection for pinpoint accuracy and blazing speed. Notably, it includes eye-detection AF for humans and animals - a modern essential for portrait and wildlife photographers. In my timed burst tests, the A6100 maintains sharp focus on fast-moving subjects at up to 11 fps with continuous autofocus tracking, outperforming most compacts by a wide margin.

This difference is stark in practical use: the WG-70 is fine for static or slow-moving subjects but will frustrate anyone relying on fast or erratic autofocus performance.

Built Tough or Built for Speed? Durability and Reliability

Perhaps the clearest division between these cameras: the Ricoh WG-70 is an all-weather champion, rated waterproof to 14m, dustproof, shock-resistant from 1.6m drops, freezeproof to -10°C, and crushproof for up to 100kgf pressure. For underwater photographers, hikers, or adventurous parents who want a no-fuss camera that won’t quit, the WG-70 is a trustworthy choice.

The Sony A6100, while solidly constructed with a magnesium alloy body and plastic components, lacks any formal weather sealing. It's vulnerable to dust and moisture ingress, requiring extra care (or protective covers) when shooting in challenging environments.

Versatility Across Photography Genres

Let’s break down how each camera fares in specific photography disciplines based on detailed testing.

Portrait Photography:
The A6100’s larger sensor and wide E-mount lenses deliver beautiful skin tones and natural bokeh, with eye-AF ensuring tack-sharp portraits even in low light. The WG-70, with fixed (28-140mm equivalent F3.5-5.5) lens and small sensor, struggles to isolate subjects from backgrounds cleanly - background blur is muted and somewhat harsh.

Landscape Photography:
The A6100’s better dynamic range, higher resolution, and wider lens selection (including ultra-wide primes) yield far more compelling landscapes. The WG-70’s small sensor can produce decent daylight snaps but images fall short in shadow detail or subtle tonality. However, WG-70 wins for hiking or water-based excursions due to its ruggedness.

Wildlife Photography:
The A6100 excels here - fast autofocus with animal eye detection, high burst frame rate, and telephoto lens compatibility. WG-70’s slower AF and limited zoom capability (5x optical) limit its usefulness.
