Choosing the right camera for your photography journey is a vital step that impacts creativity, workflow, and image quality. While both the Panasonic Lumix DMC-FS42 and the Sony Alpha NEX-3 are legacy models from the late 2000s and early 2010s, understanding their respective strengths and limitations remains relevant for collectors, budget-oriented buyers, or those seeking a compact system for specific use cases. Drawing from my 15+ years of hands-on camera testing experience, this article delves deeply into the technical architecture, real-world performance nuances, and user-focused assessments of these two cameras, guiding photographers to informed decisions tailored to their genre-specific needs.

Setting the Stage: What Are These Cameras?

Before dissecting individual features, let’s briefly contextualize each model within the evolving camera landscape.

• Panasonic Lumix DMC-FS42: Introduced in April 2009, this ultracompact point-and-shoot camera was aimed at casual users wanting a pocketable, simple camera for everyday snapshots. Its fixed lens and CCD sensor denote a straightforward imaging system with minimal manual control.

• Sony Alpha NEX-3: Released in June 2010, the NEX-3 marked Sony’s entry into mirrorless interchangeable lens cameras (MILCs) for enthusiasts stepping up from compact cameras. Featuring an APS-C CMOS sensor and Sony’s E-mount lens system, it offers far greater creative control and system expandability.

The size comparison above immediately differentiates their handling and portability: the FS42 is truly pocketable, weighing only 132 grams, whereas the NEX-3 is a compact but heftier 297 grams with significantly larger dimensions.

Sensor Technology & Image Quality: The Heart of the Matter

Arguably the most consequential difference between these two models lies in their sensor technology and resultant image quality, aspects that fundamentally affect every photographic discipline.

Panasonic FS42: Small CCD Sensor with Limited Resolution

• Sensor type/size: CCD; 1/2.5-inch (5.744 x 4.308 mm), approximately 24.74 mm² area
• Resolution: 10 megapixels (3648 × 2736 pixels)
• ISO sensitivity: 80–1000 native, up to 6400 boosted
• Color depth and dynamic range: Not independently tested, but CCD technology of this scale typically struggles with noise and narrow dynamic range
• Antialias filter: Present, which sacrifices some fine detail for moiré reduction

Small sensors like this inherently have limited light-gathering ability and, despite the respectable megapixel count, generally produce noisier images, particularly at ISOs above 400. Tight pixel pitch also means constrained dynamic range, hindering shadow recovery and highlight retention.

Sony NEX-3: Large APS-C CMOS Sensor with Superior Specs

• Sensor type/size: CMOS; APS-C sized (23.4 x 15.6 mm), about 365.04 mm² area - a 14.7× bigger sensor than the Panasonic
• Resolution: 14 megapixels (4592 × 3056 pixels)
• ISO sensitivity: 200–12800 native
• Color depth: 22.1 bits (DxO Mark)
• Dynamic range: 12 stops (excellent for its launch era)
• Low light performance: DxO low-light ISO rating of 830, remarkable for an early mirrorless

The NEX-3’s sensor - which employs Sony’s Bionz processor for noise reduction and image processing - offers a far broader tonal range, cleaner high-ISO outputs, and richer color fidelity, making it vastly more suitable for demanding photography genres.

Lens & Optics: Fixed vs Interchangeable – Creative Freedom and Optical Quality

The Panasonic FS42 integrates a fixed 33–132mm equivalent zoom lens with a variable aperture of f/2.8 to f/5.9. As a “set and forget” lens, its optical quality is typical of compact cameras - adequate for snapshots but not crafted for critical detail or shallow depth of field control.

In contrast, the Sony NEX-3 supports the full E-mount ecosystem, offering access to:

• A vast array of prime and zoom lenses (currently 121 options at release, including professional quality glass)
• Apertures as wide as f/1.4 for exquisite background separation and low-light shooting
• Macro lenses for detailed close-ups (important for those exploring beyond day-to-day photography)

This interoperability elevates the NEX-3’s versatility dramatically, empowering users to tailor optics per their genre or creative vision, an advantage unattainable on the FS42.

Autofocus and Shooting Speed: Responsiveness for Motion and Precision

Panasonic FS42: Basic Contrast-Detection AF

The FS42 features only single-shot contrast-detection autofocus without tracking - typical of ultracompacts of its time. Autofocus speed is modest, particularly in low contrast or low light conditions, making it unsuitable for subjects in motion. Continuous shooting is limited to 2 frames per second, inadequate for active sports or wildlife sequences.

Sony NEX-3: Advanced AF System for Its Class

Equipped with 25 focus points (multi-area, selective AF modes), face detection, and continuous autofocus, the NEX-3 offers significantly more reliable focus acquisition and tracking. Although it lacks phase-detection AF - common in later models - the contrast-based system performs well with static and moderately moving subjects.

Continuous shooting speed reaches 7 frames per second, providing a practical edge in capturing fleeting moments in sports and wildlife photography.

Build Quality, Ergonomics, and Control Layout: User Experience Explored

Examining the layout and usability:

• Panasonic FS42: Small form factor with minimal buttons, no manual exposure modes, no external flash support, and a fixed 2.5" screen at low 230k resolution. This limits precise control and professional workflow adaptability. The absence of any manual focus or exposure priority modes confines users to automatic settings.

• Sony NEX-3: While larger and heavier, the NEX-3 features a 3" tilting 920k resolution TFT Xtra Fine LCD, comfortable grip, and a more robust system of manual controls - shutter/aperture priority, full manual mode, exposure compensation, and custom white balance - offering photographers the flexibility that extends beyond automatic shooting.

The FS42’s lightweight convenience must be balanced against the lack of tactile and manual control that enthusiasts and pros typically require.

Viewing Systems: LCD Only, No Viewfinder

Neither camera features an electronic or optical viewfinder; photography is confined to composing on the rear LCD.

• Panasonic FS42’s 2.5" fixed, low-res display struggles in bright daylight, affecting composition precision.

• Sony NEX-3’s larger, higher-resolution tilting screen provides better visibility and flexible shooting angles.

For photographers needing an EVF, neither is suitable without an external accessory (NEX-3 did not offer one natively).
