Olympus SP-590 UZ vs Panasonic Lumix G10: A Detailed Hands-On Comparison for Photography Enthusiasts

When it comes to selecting a camera tailored to your photographic ambitions, understanding the nuances behind the specs is vital. Today, we’re diving deep into two intriguing yet fundamentally different models: the Olympus SP-590 UZ, a small sensor superzoom bridge camera, and the Panasonic Lumix DMC-G10, an entry-level mirrorless with Micro Four Thirds versatility. Both bring 12 MP sensors, yet their targeted users, system capabilities, and real-world performance diverge significantly. Having spent over 15 years rigorously testing hundreds of cameras, I bring firsthand insights to help you make an informed, confidence-backed choice.

The physical size and ergonomics between the Olympus SP-590 UZ (left) and the Panasonic G10 (right) offer critical first impressions for day-to-day handling.

Getting to Know the Cameras: Design and Handling

At a glance, the Olympus SP-590 UZ fits firmly into the classic bridge camera mold with an SLR-like body and a built-in zoom lens - a "one-stop shop" for users wanting a broad focal range in a single package. Physically smaller and slightly lighter than the Panasonic G10, it balances compactness with robustness. Though the SP-590 houses a fixed lens, its 26-676mm (equivalent) zoom range is monstrous, thanks to the small 1/2.3” CCD sensor and a 5.9× crop factor. It weighs 413 grams and measures a squat 116×84×81 mm.

The Panasonic Lumix G10, by contrast, is a classic mirrorless system camera. With an interchangeable lens mount (Micro Four Thirds), it supports over 100 native lenses - offering a path to growth and tailored optics. It sports a larger 4/3” sensor with a 2.1× crop factor, housed in a slightly bigger and chunkier body (124×90×74 mm) weighing 388 grams - so it’s marginally lighter but visually more substantial than the Olympus. There’s a palpable sturdiness and a more substantial grip, which benefits longer shooting sessions.

The ergonomic layout also reflects their target uses - a fixed-lens, casual superzoom versus a flexible entry-level system. The Olympus’s controls feel simpler, fewer buttons, more compact; Panasonic’s G10 leans into more direct manual control options, including priority modes, custom white balance, and exposure bracketing.

Top control layouts reveal Panasonic’s emphasis on advanced exposure controls and direct access, whereas Olympus simplifies with fewer dials and buttons.

Handling Summary

• Olympus SP-590 UZ: Lighter, smaller, straightforward operation, ideal for users wanting an all-in-one superzoom with minimal fuss.
• Panasonic G10: Slightly bigger but better grip and control layout; designed for users who wish to progressively deepen manual exposure skills and customize ergonomics with interchangeable lenses.

Sensor Technology and Image Quality: The Heart of the Matter

The most fundamental difference is obviously the sensor size and type - a decisive factor affecting image quality, depth of field, and performance in challenging lighting.

The Olympus SP-590 uses a 1/2.3” CCD sensor, with physical dimensions of 6.08×4.56 mm, yielding a sensor area of just 27.72 mm². It offers 12 megapixels native resolution (3968×2976), pushing the tiny sensor to extract detail. The tradeoff is inherent: smaller sensors typically struggle with noise at higher ISO and have limited dynamic range, affecting shadows and highlights.

The Panasonic G10 sports the larger Four Thirds-sized CMOS sensor (17.3×13 mm, 224.9 mm² area), maintaining the same 12 MP count (4000×3000). CMOS sensor technology here is newer, allowing faster readouts, improved sensitivity, and better noise control versus Olympus’s older CCD design. Notably, Panasonic’s sensor supports multiple aspect ratios (1:1, 4:3, 3:2, and 16:9), granting compositional flexibility.

Sensor size comparison illustrates the substantial area advantage of the Panasonic G10’s Four Thirds CMOS sensor over the Olympus’s small 1/2.3” CCD.

Real-World Images: Resolution and Dynamic Range

In my hands-on tests, the G10’s images showed markedly better dynamic range, retaining details in the shadows and highlights that the SP-590 simply couldn’t capture without clipping or noise. Sharper, more lifelike textures and natural color gradations were evident in landscape shots.

Olympus’s tiny sensor results in slightly softer details and notably more noise creeping in beyond ISO 400, especially in low light and shadow areas. Fine textures like skin and foliage lacked the nuance captured by the G10.

• Color depth: Panasonic’s DxO Color Depth score of 21.2 bits manifests as smoother tonal transitions versus Olympus’s limited output (not officially scored, but visually inferior).
• ISO performance: Panasonic maintains clean images up to ISO 800, beyond which noise increases gradually. Olympus becomes visibly grainy from ISO 400 upwards.

Image Quality Summary

• Olympus SP-590 UZ: Limited by small sensor size - adequate for casual snapshots, daylight scenes, and distant subjects, but struggles in low light and detail resolution.
• Panasonic G10: Larger sensor with advanced CMOS tech delivers superior image quality, higher dynamic range, and better high ISO performance - offering true photographic flexibility.

Autofocus and Exposure Controls: Precision in Action

Focusing systems are critical across photography genres - whether nailing the eye in portraiture or tracking a fast-moving subject.

Olympus SP-590 UZ

This camera employs contrast-detection autofocus only, lacking phase detection. Focus points are limited; no dedicated face or eye detection. It offers multi-area, center-weighted, and spot metering modes, but no continuous autofocus tracking. Minimum shutter speed tops out at 1/2000 sec, with aperture values ranging f/2.8 to f/5.0 across the zoom.

In practice, focus lag and hunting are commonplace, especially in low contrast or dim scenes. Single AF mode works adequately in bright light but isn’t ideal for sports or wildlife.

Panasonic Lumix G10

The G10 boasts an advanced contrast-detection AF system with face detection and tracking modes, allowing continuous autofocus. The proprietary Venus Engine HD II processor improves AF accuracy and speed, particularly in live view.

Your manual focus options are vast, aided by focus peaking and magnification (features I particularly appreciated when shooting macro or portraits). Focal speeds adapt from 1/60 to 1/4000 sec shutters, with flexible exposure modes (shutter/aperture priority, manual, exposure compensation ±3 EV).

Autofocus and Exposure Summary

• Olympus SP-590 UZ: Basic AF system good for static subjects in daylight but insufficient for fast action or low light.
• Panasonic G10: More responsive AF with face tracking and continuous modes, giving you a decisive edge shooting portraits, sports, and wildlife.

Build Quality and Weather Resistance: Durability Matters

Neither camera is fully weather-sealed, but the SP-590 UZ does have limited environmental sealing, though not waterproof or shockproof. Its plastic-heavy construction feels less robust than Panasonic’s more substantial grip and chassis.

The G10, while lacking official sealing, sports a slightly more solid and professional build that held up better in rugged shooting during my extended outdoor tests.

Screens and Viewfinders: Framing and Reviewing Your Shots

Comparing the rear displays: Olympus’s 2.7” fixed 230k LCD versus Panasonic’s sharper 3” 460k TFT LCD.

The SP-590 has a 2.7-inch fixed LCD with 230k resolution, which is dim and less responsive, missing touch capabilities. The electronic viewfinder is rudimentary, with no detailed specs.

The Panasonic G10 sports a brighter, larger 3-inch 460k screen and an electronic viewfinder with 202k resolution, 100% coverage, and magnification of 0.52×, offering a precise, immersive view even under strong sunlight. No touchscreen, however.

In real-world use, the G10’s interface is more responsive, smooth, and intuitive. Olympus’s fixed screen limits angles, impacting usability for low or high shooting perspectives.

Lens Ecosystem and Versatility: One Lens or Many?

The fixed lens of the SP-590 offers a hyper-telephoto 26-676 mm reach - great for casual wildlife or travel zooming but with limited aperture range (f/2.8-5.0). Macro focusing gets down to 1cm, which is impressive for close-ups with the built-in lens.

The Panasonic G10’s Micro Four Thirds mount opens doors to over 100 lenses, from ultra-fast primes for portraits, versatile zooms for landscapes, and specialized macros for extreme close-ups. This system flexibility combined with optical quality is a major draw if you anticipate evolving your photography over time.

Performance in Different Photography Disciplines

Portraits

In portraits, the G10’s larger sensor and lens options allow shallow depth of field that makes backgrounds dissolve smoothly, while Olympus struggles with flatness and harsher light transitions.

Landscape Photography

For landscape, sensor size again shifts balance decisively:

• Olympus: Limited dynamic range and resolution cap fine detail.
• Panasonic: Superior color fidelity and ability to use ND filters and wide primes boost creativity.

Weather sealing favors Panasonic slightly; Olympus’s environment sealing is minimal.

Wildlife and Sports Photography

The Olympus SP-590’s long zoom range is practical for distant wildlife, yet slow and hunting AF undermines reliability in fast or unpredictable movements.

The Panasonic G10, though lacking longer native tele lenses by default, offers faster AF with tracking, letting you nail moving subjects better.

Street Photography

For casual street shoots, Olympus is more compact and less conspicuous - beneficial for candid shots. Panasonic is bigger but still relatively discreet compared to DSLRs. Both perform moderately in low light, but G10’s low noise and improved AF tracking offer an edge.

Macro Photography

Olympus’s 1cm close focus is notable for a bridge camera, but physical lens limits reduce image quality. Panasonic’s extensive macro lens selection combined with focus aids (peaking and magnification) makes it more versatile and precise.

Night and Astro Photography

The Panasonic G10’s lower noise at higher ISO values and manual exposure options are essential for astro and night shots. Olympus’s small sensor and CCD noise limit usability beyond low to moderate ISO.

Video Capabilities

• Olympus: Max video resolution 640×480 at 30 fps – very basic.
• Panasonic: 1280×720 HD at 30 fps offers decent quality for casual video shooting.

Neither supports 4K or advanced codecs, but the G10’s sharper footage and better processing give a clear win for multimedia.
