Through comprehensive hands-on testing and comparison, this article dissects them across all major photography genres and use cases, analyzing technical specifications, real-world performance, ergonomics, and value propositions that remain relevant for educators, collectors, and budget-conscious enthusiasts alike.

A Tale of Two Bodies: Size, Handling, and Ergonomics

Before delving into image quality or feature sets, the tactile experience of using a camera heavily influences shoot enjoyment and effectiveness.

Panasonic FZ28: Compact with a Superzoom Reach

The FZ28 is a pocketable all-in-one with a fixed lens that spans an astounding 27–486mm equivalent focal length (18x zoom). At 118×75×89 mm and weighing 417 g, it comfortably fits in a large coat pocket, edging towards the heavier side for compacts of its era but still eminently portable. Its small 1/2.3” CCD sensor necessitates a compact form factor, allowing the lens barrel to retract fully and save space.

Pentax K-x: Entry-Level DSLR with Substance

In contrast, the K-x, with its 123×92×68 mm dimensions and weight of 580 g, feels considerably more substantial. The body’s classic DSLR silhouette - including an optical pentamirror viewfinder and external flash hot shoe - caters to photographers accustomed to traditional camera handling. The K-x's heft and grip design provide steadiness, particularly beneficial when using heavier lenses, despite being less pocket-friendly.

Controls and Interfaces

The top panel and control layouts further reflect their differing approaches. The FZ28 opts for minimalism: a shutter release surrounded by zoom, a relatively small mode dial, and dedicated buttons for exposure compensation and flash. The limitations of no touchscreen and low-resolution fixed LCD screen (2.7”, 230k dots) restrict interactive feedback.

Meanwhile, the K-x incorporates a more conventional DSLR interface: a modestly sized mode dial sits atop with a separate exposure compensation dial, shutter button ergonomically placed, and dedicated buttons for ISO and drive modes. The viewfinder coverage of 96% with 0.57x magnification offers better framing confidence than the electronic viewfinder in the FZ28, which lacks electronic resolution or magnification specs. Both cameras use a fixed 2.7” LCD with identical resolution, but the K-x’s TFT screen tends to provide more accurate color rendition.

Image Sensor Technology and Real-World Quality

Sensor characteristics are pivotal in defining image quality limits ranging from resolution and noise to dynamic range and depth rendition.

Sensor Type and Size: The Core Difference

The Panasonic FZ28 houses a 1/2.3” CCD sensor measuring 6.08 x 4.56 mm with a total sensor area of 27.72 mm², and a resolution of 10 megapixels (3648 × 2736 pixels). While CCDs of the time are renowned for pleasing color reproduction and low noise at base ISO, the small physical size intrinsically limits image quality potential - especially dynamic range and high ISO performance.

The Pentax K-x’s APS-C sized CMOS sensor (23.6 x 15.8 mm, 372.88 mm² sensor area) is over 13 times larger by surface area, with a marginally higher resolution of 12 megapixels (4288 × 2848 pixels). CMOS technology, integrated with the PRIME processor, enables faster readout, improved noise handling, and greater dynamic range, key for demanding disciplines such as landscapes and sports.

Technical Image Quality Metrics (DXOMark Scores)

• Panasonic FZ28: Overall 27, Color Depth 17.9 bits, Dynamic Range 10.1 EV, Low-Light ISO Score 79
• Pentax K-x: Overall 72, Color Depth 22.8 bits, Dynamic Range 12.5 EV, Low-Light ISO Score 811

This quantitative leap highlights the K-x’s superior latitude for shadows and highlights, finer tonal gradation, and far stronger performance at elevated ISOs - critical for low-light conditions and preserving detail in challenging scenarios.

Raw Format Capability

Both cameras support RAW shooting, a crucial feature for post-processing control. Panasonic employs its own RW2 format, while Pentax uses PEF and DNG, the latter widely supported in mainstream raw processors, enhancing workflow integration.

Autofocus and Exposure: Speed, Accuracy, and Usability

Autofocus (AF) and metering systems strongly impact success in capturing sharp, well-exposed images, especially in dynamic environments.

Panasonic FZ28: Contrast-Detection Simplicity

The FZ28 relies solely on contrast-detection autofocus within live view mode, with single AF mode only - no continuous autofocus or tracking options. Lack of face or eye detection reduces responsiveness for portrait or action-centric scenarios. The camera lacks AF point selection or multiple AF areas, defaulting to center-weighted focusing, which can be limiting.

Exposure control is comprehensive with manual, aperture priority, shutter priority modes, and an exposure compensation dial, but metering sensibility is limited: no multi-segment matrix metering; it uses center-weighted or average metering modes only. This can challenge accuracy in difficult lighting. The shutter speeds range from 60s to 1/2000s.

Pentax K-x: Phase Detection Speed and Flexibility

In contrast, the K-x boasts a 11-point phase-detection AF system, including multi-area and selective spot modes, and crucially offers continuous autofocus tracking for moving subjects. The inclusion of face detection further enhances usability for portraiture.

Metering includes multi-segment, center-weighted, and spot options, providing superior exposure accuracy in complex lighting setups. Shutter speeds extend from 30s up to 1/6000s, offering better capability for freezing action or long exposures.

Both feature manual focus support, but the K-x’s compatibility with over 150 Pentax K-mount lenses adds flexibility and sharpness advantage through high-quality optics unavailable on fixed lens cameras.

Zoom and Lens Ecosystem: Flexibility vs. Convenience

FZ28: Fixed 18x Optical Zoom, Reasonable Aperture Range

The FZ28’s 27–486 mm equivalent zoom lens with an aperture range of f/2.8–4.4 covers wide-angle to super-telephoto focal lengths, making it a versatile tool for casual travel and wildlife enthusiasts seeking reach without lens changes. The built-in optical image stabilization (OIS) helps mitigate camera shake at long focal lengths, crucial given the small sensor's susceptibility to diffraction and noise.

However, the fixed lens limits optical quality at extremes, and the variable aperture means lower-light telephoto shots suffer from narrower apertures influencing depth of field and shutter speed options.

K-x: Interchangeable Lens System with Wide Variety

As an interchangeable lens DSLR, the K-x inherits the flexibility and quality advantages of the Pentax KAF2 mount, boasting a vast range of compatible prime and zoom lenses, including specialized primes for macro and fast aperture portraiture. Sensor-based stabilization, a key feature absent in Panasonic’s lens, enhances handheld shooting across all lenses.

The focal length multiplier of 1.5x means a 50mm lens yields a 75mm equivalent field of view, important for telephoto reach but modest for ultra-wide-angle photography, which Pentax lenses address with specialized wide lenses.

Shooting Experience: Viewfinder, LCD, and Usability

Both cameras offer live view modes with 2.7-inch fixed LCDs at 230k dots, common in 2009 but modest by today’s standards. The FZ28 uses an electronic viewfinder with unreported resolution - basically functional but pixelated, making manual focus assessments tricky.

The K-x’s optical pentamirror viewfinder, with 96% frame coverage, offers clearer, lag-free framing with direct optical feedback, prized by seasoned photographers for precision focusing and exposure estimation. The downside is optical viewfinders lack an overlay of real-time exposure info found in some mirrorless EVFs.

Raw Performance in Varied Genres of Photography

Portrait Photography: Who Captures Skin Tones Best?

Pentax K-x's sensor and color depth provide superior skin tone rendition, nuanced gradations, and pleasing bokeh when paired with fast primes or standard zoom lenses. Face detection AF aids sharp eye focus, enhancing portrait sharpness. The FZ28, while featuring a modest lens aperture and no face detection, can produce decent results under adequate lighting but struggles with creamy background separation and autofocus precision.

Landscape Photography: Dynamic Range and Resolution Count

K-x excels with high dynamic range (12.5 EV vs. 10.1 EV) and larger sensor resolution, capable of capturing intricate detail and shadow detail crucial in landscapes. The dust and weather sealing are absent in both, so cautious field use is advised, though K-x's lens protection options help. The FZ28’s limited dynamic range and sensor resolution restrict its appeal here.

Wildlife and Sports: Autofocus Speed and Burst Rate Tell

FZ28’s 3 fps continuous shooting and contrast-detection AF limit efficacy in tracking fast-moving wildlife or sports subjects. Conversely, K-x’s 5 fps burst rate and phase-detection AF with continuous mode offer better capturing of action sequences, though still modest compared to modern standards.

Street Photography: Discreteness vs. Image Quality

FZ28's compact size and long zoom offer discretion in street photography but with limitations in low light and subtle exposure control. K-x’s larger form factor may attract attention but rewards with superior image quality and manual control, favored by enthusiasts on a budget.
