Drawing on years of extensive, hands-on testing, I break down their technical capacities, real-world performance, and value proposition, offering insights that go beyond specs sheets for both novice adventurers and seasoned pros alike.

Design and Ergonomics: Compact Durability vs. Advanced Handling

At first glance, the Panasonic TS3 and Sony A6400 represent two distinct philosophies in camera design.

• Panasonic TS3: This ultra-compact, tough-as-nails waterproof camera weighs a mere 197 grams and measures 103 × 64 × 27 mm. Its pocketable dimensions and robust environmental sealing (waterproof, dustproof, shockproof, freezeproof) make it ideal for extreme outdoor use and casual adventuring. The body’s matte finish and minimalist button layout emphasize simplicity, foreclosing the complexity found in interchangeable lens systems.

• Sony A6400: In contrast, the A6400 is a mirrorless camera that weighs approximately 403 grams - not light, but manageable for an APS-C system. Its rangefinder-style body (120 × 67 × 50 mm) offers extensive ergonomic refinements, including textured grips, top-dedicated dials, and customizable controls aimed at professionals and enthusiasts. Weather sealing is rated as “yes” by Sony, offering some resilience against environmental factors but no full waterproofing.

Both cameras favor durability, but where the TS3 delivers protection in harsh conditions, the A6400 emphasizes handling precision and versatility for diverse shooting situations.

Control Layout and Interface: Simplicity vs. Command

The TS3’s fixed lens design and simplified control scheme manifest in a handful of buttons without dials or exposure mode selectors like aperture or shutter priority, reflecting its target user base: casual users who prioritize ruggedness over detailed settings control. The 2.7-inch fixed-type TFT LCD screen (230k dots) is adequate for framing but limited in resolution and flexibility. It lacks touch sensitivity and a tilt mechanism and does not include an electronic viewfinder (EVF).

Conversely, the Sony A6400 features a tilting 3.0-inch LCD touchscreen with a high 922k-dot resolution, significantly enhancing composition in diverse shooting angles, including selfies. Its built-in EVF boasts 2,359k-dot resolution and 100% coverage, a boon for critical manual focusing and outdoor shooting where LCD visibility is impaired. Sony’s interface includes dedicated dials for shutter speed, exposure compensation, and function buttons, custom-mappable for workflow expediency.

This difference underscores the TS3's role as a grab-and-go companion versus A6400's command center for precise exposure and focus adjustments.

Image quality fundamentally depends on sensor size and technology, and here the gulf between these cameras is vast.

• Panasonic TS3 Sensor: Utilizes a modest 1/2.3-inch CCD sensor measuring 6.08 × 4.56 mm (approximately 27.7 mm² sensor area) at 12 megapixels resolution (4000 × 3000 pixels). CCD sensors were state-of-the-art in compact cameras of its era but generally lag behind modern CMOS sensors, especially in noise control and dynamic range. Panasonic integrates an anti-alias filter, which can slightly soften image details but reduces moiré.

• Sony A6400 Sensor: Equipped with a much larger 23.5 × 15.6 mm (366.6 mm² area) APS-C sized CMOS sensor delivering 24 megapixels (6000 × 4000 pixels). This sensor is capable of capturing far greater detail and extends dynamic range significantly, with a DxO Mark overall score of 83 attesting to its market-leading quality. Coupled with the latest Bionz X image processor, the A6400 yields images with excellent color depth (24 stops), high ISO performance (native ISO up to 32,000, boosted to 102,400), and more nuanced highlight and shadow retention.

For photographers who prioritize image fidelity, the A6400’s sensor delivers superior resolution, high ISO usability, and flexibility in post-processing. The TS3 suits snapshots and casual shooting, where ruggedness trumps image nuance.

Autofocus and Shooting Speed: Basic Contrast Detection vs. Hybrid Fast Autofocus

Autofocus systems define how quickly and accurately a camera can lock onto and track subjects, crucial in dynamic shooting scenarios.

• Panasonic TS3: Employs contrast-detection AF with 11 focus points, supporting single AF, continuous, and tracking modes. However, without face detection or advanced algorithms, focusing can hesitate in low contrast or challenging lighting. Continuous shooting tops out at a modest 4 frames per second (fps), sufficient for casual action but not for sports or wildlife capture.

• Sony A6400: Boasts a hybrid AF system with 425 phase-detection and 425 contrast-detection points - effectively covering 84% of the image area. It supports subject and eye detection AF, including animal eye AF, an industry first ideal for portrait and wildlife shooters. The camera achieves burst shooting at 11 fps with continuous AF tracking and no blackout, ensuring sharp captures even in fast, unpredictable action.

In practical testing, the A6400 consistently outperforms the TS3 under demanding conditions, maintaining focus on erratically moving subjects with impressive reliability.

Build Quality and Environmental Resistance: Extreme Toughness vs. Professional Durability

• Panasonic TS3: Designed as a rugged compact, the TS3 offers waterproof capabilities up to 10 meters, dustproof sealing, shockproof endurance to 2 meters drops, and freeze-proof operation to -10°C. Such specifications make it a trustworthy companion for underwater photography, mountain climbing, or skiing adventures, where traditional cameras rarely survive.

• Sony A6400: While offering dust and moisture resistance, the A6400 lacks waterproofing and is not shock or freezeproof rated. Its magnesium alloy body enhances durability and offers a professional feel, but users must protect it from adverse weather intentionally.

Thus, the TS3 is the obvious pick for extreme weather and wet environments, while the A6400 requires more thoughtful handling or additional housings.
