While these two cameras belong to different design philosophies and technology generations, their comparison sheds light on how rapid technological advancement reshapes photographic tools and user experiences. Drawing on extensive hands-on testing methodologies and technical scrutiny amassed from decades of camera evaluations, this 2500-word comparative analysis provides photography enthusiasts and professionals an authoritative resource to understand practical implications, strengths, and trade-offs before deciding which camera fits their creative goals.

Taking Stock: Design, Ergonomics, and Handling

When holding the Olympus SP-590 UZ and Panasonic GX8 side by side, their physical attributes immediately distinguish their intended user experiences. The SP-590 UZ, designed in traditional SLR-like bridge fashion, features a chunky grip-balanced body measuring approximately 116 × 84 × 81 mm and weighing about 413 g. Its faux-DSLR silhouette invites users familiar with larger cameras but its fixed lens limits lens adaptability. The ergonomics prioritize zoom handling with a broad lens barrel dominating the front, equipped with expansive zoom ranges for versatility, but the layout can feel somewhat dated by contemporary standards.

The GX8, conversely, embodies a sleek rangefinder-style mirrorless architecture. It is moderately larger in body size (133 × 78 × 63 mm) and marginally heavier at 487 g, reflecting sophisticated internal mechanics - such as a digital viewfinder sensor stack and in-body stabilization mechanisms. Its relatively compact depth (63 mm) and refined grip make it highly maneuverable for street, travel, and event photography. While the GX8 eschews an integrated flash, it compensates with customization through external flash units and a comprehensive control layout conducive to manual shooting styles.

Ergonomically, the GX8 handily outpaces the SP-590 UZ, thanks in part to its clearly defined mode dials, configurable buttons, and a fully articulated touchscreen, which the Olympus lacks. The bridge-style camera’s more basic control interface reflects its point-and-shoot heritage aimed at casual users needing minimal manual input.

Controls and Interface: Intuitive or Complex?

The top-panel real estate speaks volumes about usability. The SP-590 UZ’s modest control array focuses on automated and semi-manual modes (shutter/aperture priority), with tactile dials and buttons. The absence of a fully articulated screen and touchscreen limits rapid adjustments, making it less ideal for interactive shooting scenarios or those desiring touchscreen-driven AF or exposure control.

The GX8 boldly counters with an extensive complement of dials - exposure compensation, shutter speed, and mode selectors - and a configurable function button extending workflow flexibility. Its 3.0-inch fully articulated touchscreen (1040k dots) represents a massive usability leap over the SP-590’s fixed 2.7-inch 230k dot screen, enabling touch-focus, menu navigation, and selfie framing.

Though the Olympus supports basic exposure compensation and manual modes, the Panasonic opens the door to nuanced exposure stamping, multiple bracketing options, and faster AF mode switching, all crucial for both professional shooting and precise enthusiast control.

Sensor Technologies and Image Quality: The Heart of the Camera

At the core, image quality is largely governed by sensor technology. The two models under consideration present stark contrasts owing to technological leaps and sensor formats.

The Olympus SP-590 UZ relies on a 1/2.3-inch CCD sensor measuring a modest 6.08 × 4.56 mm, featuring approximately 12 megapixels with a maximum native ISO of 6400. The physical sensor area is around 27.72 mm², which - while respectable in the compact domain - significantly restricts light gathering compared to larger sensors. CCD sensors typically produce pleasing color tones at low ISOs but suffer at higher sensitivities with pronounced noise, limited dynamic range, and reduced high ISO usability. Furthermore, the SP-590 UZ only outputs raw files in theory, but due to its sensor and processor limitations, the flexibility afforded by raw editing is comparatively narrow.

In contrast, the Panasonic GX8 houses a Four Thirds CMOS sensor measuring 17.3 × 13 mm, delivering a considerable 20-megapixel resolution, and covers an area of about 224.9 mm² - over eight times larger than the Olympus sensor. Thanks to this, the GX8 benefits from substantially better image quality, with improved dynamic range (DxOMark scores affirm 12.6 EV vs the untested but lower-performing Olympus), enhanced color depth (~23.5 bits for Panasonic), and superior high ISO performance (up to ISO 25600 native, effectively usable up to ISO 3200-6400 depending on noise tolerance).

The GX8’s signal-to-noise ratio and sensor architecture facilitate shadow recovery and highlight retention, enabling expansive post-processing latitude, making it a workhorse for professionals and enthusiasts shooting in variable conditions.

In practical tests, the Olympus sensor limits landscape and low-light performance with muted dynamic range and noticeable noise artifacts at ISO gains, whereas the GX8 confidently retrieves deep shadow detail with minimal chroma noise and exceptionally fine detail resolution, ideal for large prints and pixel-peeping.

Autofocus Systems and Shooting Speed: Precision Meets Performance

Arguably crucial for genres like wildlife and sports photography, autofocus performance and shooting speed mark a definitive divide between these cameras.

The Olympus SP-590 UZ employs a basic contrast-detection only autofocus (AF) system, lacking phase-detection or hybrid AF technologies, common for cameras circa 2009. It features multi-area AF but no face or eye detection, and does not support continuous autofocus during burst shooting. Focusing speed is generally slow, especially in low contrast or low light, restricting its ability to capture rapid movement or fleeting moments reliably. Continuous shooting maxes out at a modest 6 frames per second (fps), but the buffer depth and autofocus velocity dampen its utility for action shooters.

The Panasonic GX8, meanwhile, incorporates a highly sensitive contrast-detection AF paired with Depth from Defocus (DFD) technology, improving continuous autofocus tracking. Its AF system packs 49 focus points, supports face detection, and for the first time in Panasonic’s lineup introduces AF tracking to maintain focus on moving subjects - vital for wildlife and sports photography. The continuous burst rate doubles to 12 fps, with responsive AF, making it adept at locking onto fast-moving targets.

In practical shooting scenarios, the GX8’s autofocus demonstrates excellent low-light accuracy and confidence, locking within milliseconds even in challenging environments. The Olympus system tends to hunt for focus and occasionally misfocuses in dynamic or dim conditions.

Build Quality and Weather Resistance: Ready for More?

The ruggedness of a camera body matters profoundly to professionals shooting outdoors and travelers seeking dependable gear.

Despite its age, the Olympus SP-590 UZ does feature environmental sealing, though it is not marketed as weatherproof or shock resistant.

Its fixed lens design limits the risk of dust ingress compared to interchangeable lens systems.

The Panasonic GX8 advances further with comprehensive weather sealing, including dust and splash resistance, combined with a durable magnesium alloy body, offering enhanced protection for fieldwork and adverse conditions.

Markedly, the GX8 omits waterproofing or shockproof certifications, but its build quality and sealing systems surpass the SP-590’s in reliability and longevity under rigorous use.

Displays and Viewfinders: Critical Eyes and Composition Tools

Display and viewfinder quality directly affect framing, focusing, and reviewing images.

The SP-590 UZ sports a 2.7-inch fixed LCD screen with a low resolution of 230k dots, delivering basic image playback but falling short aesthetically for critical focus checking or menu navigation. Its electronic viewfinder, lacking resolution specification, tends to be dim and pixelated, limiting composing precision especially in bright conditions.

The GX8 improves markedly with a vibrant 3.0-inch fully articulating touchscreen at a crisp 1040k dots, allowing tilt and swivel movements ideal for video, low-angle, or self-portrait shooting. The touchscreen simplifies focus point adjustments, menu navigation, and image review.

Moreover, the GX8’s electronic viewfinder offers a premium 2,360k-dot resolution and near 100% frame coverage with 0.77x magnification, delivering a clear, high-resolution live preview replicating optical viewfinder behavior. This markedly enhances manual focusing, exposure checking, and overall shooting accuracy, particularly vital for critical work.

Lens Ecosystem and Optical Versatility: Fixed Zoom vs. Micro Four Thirds

The SP-590 UZ bridges telescope-like superzoom demands with its fixed 26-676 mm equivalent lens, covering a whopping 5.9x focal length multiplier. This range is ideal for casual wildlife, travel, and general photography without the need to carry extra lenses. Its maximum aperture of f/2.8 to f/5.0 is moderate, and macro focusing down to 1 cm facilitates close-up shots, though optical quality - given the superzoom compromises - falters at telephoto extremes with softness and chromatic aberrations.

On the other hand, the Panasonic GX8’s Micro Four Thirds mount opens doors to an expansive, well-established lens ecosystem of over 100 native lenses offered by Panasonic, Olympus, Sigma, and third parties. Lens options stretch from ultra-wide primes and fast portrait lenses to professional-grade telephotos and macro optics, enabling photographers to tailor glass to specific needs.

Though the GX8 lacks an included lens in the specs provided, it pairs perfectly with Panasonic’s own Leica DG Summilux primes or Olympus’s M.Zuiko lenses, boasting constant apertures and superior optical corrections. This interchangeability reflects its intent as an advanced creative tool - the antithesis of the fixed-lens bridge camera model.
