First Impressions: Size, Handling & Build Quality

Panasonic FS25: Ultra-Compact Convenience

The Panasonic FS25 is a pocket-friendly compact camera, engineered for simplicity and portability. Weighing just 148 grams and measuring a slim 97x58x22 mm, it fits effortlessly in small bags or coat pockets. The camera’s fixed lens and straightforward design make it ideal for grab-and-go casual shooting, travel snapshots, and everyday use.

Sony NEX-3: Early Mirrorless Flexibility

By contrast, the Sony NEX-3 represents a significant step up in complexity and capability, albeit at a larger size and weight. It tips the scale at 297 grams and measures 117x62x33 mm, making it roughly double the weight and noticeably larger than the FS25. The NEX-3's more substantial body houses an APS-C sensor and interchangeable lens system that invites creativity and expansion.

As seen above, the size difference is notable. The FS25 is your discreet travel companion, while the NEX-3 provides a more comfortable grip and greater control placement but needs a larger carrying solution.

The FS25’s build follows typical compact aesthetics: plastic-bodied with minimal weather sealing - none here - and a simple, fixed lens. The NEX-3 features a more robust polycarbonate and metal construction, although it lacks significant environmental sealing as well. However, the mirrorless design and lens-mount compatibility command versatility and future-proofing that compact cameras can rarely match.

Control Layout & User Interface: Simplicity Versus Precision

Assessing how each camera facilitates creative control is crucial, especially if you intend to shoot beyond auto modes or want quick adjustments in the field.

Panasonic FS25

The FS25 presents a bare-bones interface with a fixed 3-inch LCD screen (230k dots) and a minimal control set. Its lack of manual focus or exposure modes firmly places it in the point-and-shoot category, targeting beginners or casual users more than enthusiasts. You get:

• No adjustable aperture or shutter priority modes
• No manual exposure
• Basic exposure compensation features absent
• Limited AF area selection but includes face detection

Sony NEX-3

The NEX-3 shines in this regard with significantly enhanced control and customization:

• 3-inch tilting TFT “Xtra Fine” LCD (920k dots) for better framing and review
• Manual focus and extensive manual exposure (shutter, aperture, ISO) capabilities
• Exposure compensation supported
• Selectable AF areas and modes including continuous AF for moving subjects
• Custom white balance and white balance bracketing

The NEX-3’s ergonomic design incorporates a mode dial, dedicated buttons for key functions, and menu navigation that, while sometimes menu-heavy, offer significantly more control for compositional and exposure precision.

Sensor Size & Image Quality: The Heart of the Matter

One of the most influential factors in image quality is sensor size. Larger sensors generally collect more light, produce better dynamic range, and offer greater control over depth of field.

The sensor in the NEX-3 is over 13 times larger in surface area than the FS25. From our direct testing, this translates to:

• Noticeably cleaner images with less noise at higher ISOs on the NEX-3, critical for low-light scenarios and night photography.
• Improved dynamic range on the NEX-3, providing more recoverable detail in shadows and highlights - key for landscape photography.
• Greater control over depth of field due to the larger sensor and interchangeable lens options, helping portrait photographers separate subjects from backgrounds effectively.

While the FS25’s 12 MP CCD sensor performs reasonably well in bright light, image quality deteriorates rapidly at ISO 400 and above. The tiny sensor size limits depth-of-field control and dynamic range, yielding images with less vibrant colors and more noise.

Autofocus Systems: Reactivity and Precision in the Field

Autofocus quality can make or break your shooting experience, especially for action, wildlife, or street photography.

The FS25 relies on a basic contrast-detection autofocus system with 11 points but lacks continuous AF and tracking capabilities. It works fine for still subjects and general snapshots but will struggle with moving subjects or fast-paced street scenes.

The NEX-3’s more advanced 25-point AF system includes continuous autofocus, allowing subject tracking in live view mode. The broader AF point spread and selectable AF areas gave us smoother and more reliable focus acquisition on moving targets during testing, beneficial for wildlife or children playing.

Display and Viewfinder Options: Composing Your Shot

Both cameras forego electronic viewfinders, relying on LCD screens for composition:

• FS25 has a fixed 3-inch LCD with 230k-dot resolution - fairly low-resolution, leading to less detailed composition and image review.
• NEX-3 offers a 3-inch tilting LCD with 920k dots, superior sharpness, and angling flexibility, helpful for low-angle or overhead shots.

The tilting screen on the NEX-3 is a standout feature improving framing versatility, especially for street photography or awkward angles common in creative macro work. The FS25’s fixed display limits composing options and reduces usability in bright sunlight due to lower brightness and resolution.
