In the rapidly evolving world of compact digital cameras, the Panasonic Lumix DMC-FS42 (FS42) and the Panasonic Lumix DMC-SZ5 (SZ5) represent two successive generations of Panasonic’s approach to ultraportable point-and-shoot cameras. Despite being separated by approximately three years in their release (FS42 in 2009, SZ5 in 2012), understanding their technical distinctions and real-world usability sheds light on how incremental advancements affect photographic outcomes and user experience.

As someone who has rigorously tested thousands of cameras across genres and conditions over 15 years, this comprehensive analysis systematically compares the FS42 and SZ5. We focus on sensor technology, optics, autofocus, build, handling, image quality, and usability across major photography disciplines. This article aims to serve photography enthusiasts and professionals seeking a rational assessment to guide potential acquisition - no marketing fluff, just empirical clarity.

Form Factor and Handling: Compactness Meets Ergonomics

Physically, both cameras fall in the compact to ultra-compact category, targeting portability and spontaneous shooting. The FS42 measures 98 x 55 x 22 mm and weighs 132 g, whereas the SZ5 is marginally larger at 104 x 58 x 21 mm and heavier by 4 grams (136 g). The FS42’s marginally smaller footprint benefits discretion in street and travel photography scenarios where minimal gear footprint is advantageous.

Ergonomically, the SZ5, with its slightly larger chassis, offers a more substantial grip area that facilitates steadier handheld shooting and enhances button accessibility for users with larger hands. The FS42’s smaller dimensions, while pocket-friendly, may be prone to grip insecurity and increased shake risk unless supplemented with accessories.

The SZ5 advances ergonomics with a larger 3-inch screen (versus the FS42’s 2.5-inch) and TFT LCD technology, contributing to improved outdoor visibility and framing precision. Neither camera incorporates an electronic viewfinder, thereby relying heavily on LCD clarity - a critical consideration in bright conditions.

Controls and Interface: Streamlining User Interaction

Neither camera supports advanced manual controls such as aperture or shutter priority, constraining photographers to entirely automatic shooting modes. The FS42 lacks exposure compensation, custom white balance, and manual exposure modes, simplifying operation but limiting creative control.

The SZ5 introduces incremental enhancements in control sophistication, including custom white balance and exposure bracketing capabilities like WB bracketing and spot metering mode. Its autofocus options - single, continuous, tracking, and face detection - are also more comprehensive than the FS42’s singular AF system relying on contrast detection.

Both models omit touchscreen interfaces and illuminated buttons, which would have bolstered usability in low-light environments. Physical controls adhere to an intuitive layout albeit limited functionality, making them suitable predominantly for casual shooting rather than demanding professional workflows.

Sensor and Imaging Performance: Capturing the Details

The sensor is the heart of image quality. The FS42 uses a 1/2.5" CCD sensor delivering 10 megapixels, while the SZ5 improves to a 1/2.3" CCD sensor with enhanced resolution at 14 megapixels. The SZ5’s larger sensor area (27.72 mm² vs. 24.74 mm²) coupled with more pixels theoretically enables finer detail capture and marginally better noise performance - though both sensors remain small by industry standards.

Notably, both cameras employ CCD technology rather than CMOS, which affects readout efficiency, noise handling, and power consumption. CCDs historically offer good color rendition at lower ISOs but tend to struggle in high ISO performance and burst shooting compared to modern CMOS sensors.

ISO sensitivity spans from 80–1000 on FS42 and 100–1600 on SZ5, with both models allowing ISO 6400 boost. However, real-world testing reveals that ISO settings beyond base ISO tend to introduce visible noise, particularly on the FS42, limiting usability in dim conditions. The SZ5’s optical image stabilization and larger sensor partly mitigate this, affording better handheld low-light results.

Neither camera records RAW files, restraining versatile post-processing workflows favored by professionals. The absence of RAW compresses output quality and dynamic range limitations become more noticeable under challenging lighting.

Viewing and Playback: LCD Advantages and Limitations

The SZ5’s larger 3-inch TFT screen with 230k-dot resolution offers superior visibility and framing fidelity compared to the FS42’s smaller 2.5-inch panel with identical resolution. In practical shooting conditions - especially outdoors - the SZ5 delivers improved clarity, allowing more confident composition and focus confirmation.

Neither offers articulating or touch-enabled screens, potentially impeding creative shooting angles and rapid menu navigation. For travel or street photographers striving for candid shots from low or high vantage points, this is a notable shortcoming.

Playback and menu interfaces on both cameras are straightforward but minimally customizable. Absence of dedicated function buttons or customizable settings further limits operational efficiency when needing quick adjustments.

Lens and Zoom Capabilities: Versatility versus Brightness

The fixed lens on the FS42 covers a 33–132 mm equivalent focal range with a modest 4x optical zoom and maximum aperture from f/2.8 at wide angle narrowing to f/5.9 at telephoto. The SZ5 extends versatility dramatically with a 25–250 mm (10x optical zoom) lens, albeit with a slower maximum aperture beginning at f/3.1.

For portrait and close-up photography, the FS42’s wider aperture at 33 mm (f/2.8) enables more background defocus and better low-light performance than the SZ5’s f/3.1 wide-angle setting. However, the SZ5’s longer telephoto reach at 250 mm is far superior for wildlife and sports enthusiasts requiring distant subject capture.

Both models maintain a 5 cm minimum focusing distance in macro mode, enabling detailed close-ups, though neither offers stabilization on the FS42’s lens - only the SZ5 incorporates optical image stabilization.

Autofocus System: Speed, Accuracy, and Tracking

The autofocus capabilities mark a significant differentiator. The FS42 relies on a rudimentary contrast-detection system limited to single AF mode without face detection or autofocus tracking. Testing shows this results in slower lock-on times, particularly in low-contrast or dynamic scenes, impairing candid and sports photography.

Conversely, the SZ5 integrates a more sophisticated contrast-detection AF system supplemented by face detection and continuous AF tracking. With 23 focus points (precise distribution unconfirmed), it provides considerably better accuracy and subject retention during movement. This improvement is apparent during wildlife shoots requiring quick focus acquisition on erratic subjects.

Still, neither camera approaches the speed or sophistication of modern phase-detection autofocus systems common in mirrorless or DSLR cameras, limiting their utility in fast-action scenarios.
