Its rangefinder-style body offers a sophisticated feel, superior control ergonomics, and a well-laid out button array suited for enthusiasts and pros. The A6100 sacrifices weather sealing for a compact, lightweight design, favoring portability over ruggedness.

The Sony’s top control dials and customizable buttons provide tactile feedback and quick adjustments - something I appreciated when shooting fast-paced action. The WG-6’s simpler controls reflect its point-and-shoot focus, lacking dedicated dials or exposure modes like aperture priority.

Summary:
If you need a tough camera that can take a beating in outdoor adventures, the WG-6’s weather-proofing is unmatched. The A6100 offers more refined controls and ergonomics, ideal for deliberate shooting but less suited for rugged usage.

Sensor and Image Quality: The Heart of the Camera

The sensor size and technology dramatically influence image quality, dynamic range, and noise performance, making it an essential comparison factor.

Ricoh WG-6: Equipped with a 1/2.3-inch BSI-CMOS sensor sporting 20MP resolution (5184x3888). The sensor measures approximately 6.17x4.55mm, producing decent image quality for a compact. However, this small sensor size limits dynamic range and low-light performance, common among rugged compacts.

Sony A6100: Uses a significantly larger APS-C sized CMOS sensor measuring 23.5x15.6mm with 24MP resolution (6000x4000). The bigger sensor grants the A6100 superior image quality, better dynamic range, impressive low-light prowess with native ISO up to 32000 (expandable 51200), and a shallower depth of field for creative control.

Hands-on notes:
In practical testing, the A6100’s sensor delivered crisp, noise-free images even at ISO 3200 - which the WG-6 struggled to match beyond ISO 800. Dynamic range in the Sony preserved highlight and shadow detail remarkably well, essential for landscape and portrait work. The Ricoh’s sensor, while solid for casual snaps, cannot rival this breadth.

Summary:
The A6100 dominates image quality, offering vibrant colors, fine detail, and flexibility needed for professional applications. The WG-6’s sensor is fine for snapshots in tough conditions but won’t satisfy enthusiasts prioritizing creative image quality.

Autofocus and Speed: Tackling the Action

Autofocus and shooting speed determine whether you’ll capture decisive moments, especially in wildlife and sports.

Ricoh WG-6: Utilizes contrast-detection AF with only 9 focus points and supports face detection. Continuous AF and tracking exist but remain basic and relatively slow due to its compact sensor and processor design.

Sony A6100: Features a hybrid AF system combining phase-detection and contrast detection with 425 focus points spread densely across the frame. Includes face and eye detection, plus animal eye detection for wildlife. The camera supports continuous autofocus at up to 11 frames per second burst shooting, excellent for fast action.

In my field tests, the A6100 locked focus swiftly and tracked moving subjects accurately across a variety of scenes - from chasing birds in flight to indoor basketball games. The WG-6 struggled to maintain focus on fast subjects, often hunting or missing errant focus in low contrast or low light.

Summary:
For photographers prioritizing speed and reliable autofocus - sports, wildlife, and dynamic street photography - the Sony A6100 is far superior. The WG-6 autofocus is acceptable for casual use but limiting for serious action shooters.

Usability and Interface: Navigating Menus and Controls

The user interface affects how quickly and intuitively you can operate the camera under various conditions.

Ricoh WG-6: Sports a 3-inch fixed LCD with 1040k dots; it is not touch-sensitive, and the menu system is straightforward but lacks depth. There’s no electronic viewfinder (EVF), so composing in bright sunlight can be challenging. Due to its rugged design, the buttons aren’t illuminated.

Sony A6100: Features a 3-inch 922k-dot tilting touchscreen LCD plus a 1440k-dot EVF providing 100% coverage and 0.71x magnification. The touchscreen is highly responsive for autofocus point selection and menu navigation. Menus are rich but well-organized, including customizable buttons.

From experience, the A6100’s tilting screen and EVF make it comfortable to frame shots at eye level or awkward angles - very useful for portraits and street shots. Conversely, the WG-6’s fixed screen means you sacrifice compositional flexibility.

Summary:
The Sony offers a more versatile, user-friendly interface with EVF and touch controls. The Ricoh sticks to basics, built for durability rather than interface sophistication.

Lens and System Compatibility: How Far Can You Go?

Lens options dictate creativity and adaptability across genres.

Ricoh WG-6: Comes with a fixed 28-140mm (35mm equivalent) f/3.5-5.5 zoom lens covering moderate wide to telephoto range. While versatile at its scale, it’s a step above basic digital compacts thanks to its macro focus to 1cm. However, you cannot change or upgrade the lens.

Sony A6100: Uses Sony’s expansive E-mount system with over 120 lenses available, including primes, zooms, macros, and specialty glass from Sony and third-party makers. This system flexibility is a massive asset for evolving your photography skills and styles.

Real-world implication:
While the WG-6’s lens is handy for travel and outdoor tasks (especially macro close-ups), it can’t compete with the A6100’s growing system. On the Sony, you can pair bright fast primes for portraits, super-tele zooms for wildlife, or specialized lenses for macro and astrophotography.

Summary:
Sony’s lens ecosystem is a clear winner, offering unmatched versatility. The WG-6’s fixed lens is simpler but limited to adventure-centric focal lengths.

Durability and Weather Resistance: Built for the Elements?

The ability to shoot in extreme conditions without damage can be a dealbreaker for many.

Ricoh WG-6: Built to military-grade standards featuring waterproofing to 20m (66 feet), dustproof, shockproof (against 2-meter drops), freezeproof to -10°C, and crushproof up to 100kgf. This makes it one of the toughest compacts you can buy.

Sony A6100: Has no weather sealing or rugged protective features. It requires careful handling to avoid moisture and dust ingress, making it best suited for controlled environments or when paired with protective accessories outdoors.

If you frequently shoot diving, backpacking in harsh environments, or work in unpredictable weather, the WG-6 offers peace of mind that your camera will survive conditions that would sideline mirrorless cameras.
