Olympus SP-590 UZ vs. Panasonic Lumix DMC-LZ20: A Meticulous Examination of Two Small Sensor Superzoom Cameras

In the fast-evolving world of digital photography, consumers often face challenging decisions when selecting cameras that best fit their diverse requirements. This comparison aims to unravel the practical distinctions and shared characteristics between two contemporaneous small sensor superzoom bridge cameras: the Olympus SP-590 UZ (announced January 2009) and the Panasonic Lumix DMC-LZ20 (announced July 2012). Both have targeted enthusiasts desiring extensive zoom reach within a compact form factor, yet their design philosophies and execution differ, warranting an exhaustive evaluation.

Drawing on over 15 years of rigorous camera testing - including sensor benchmarking, autofocus evaluation, real-world photographic trials, and ergonomics analysis - this article provides photographers with the nuanced insights needed to make an informed decision tailored to their photographic disciplines and technical expectations.

Physical Dimensions and Handling: Size and Ergonomics in Context

Before delving into technical innards, understanding the physicality and user interface of each camera is paramount. Handling dynamics directly influence shooting comfort, stability, and the ability to react swiftly in various photography scenarios.

The Olympus SP-590 UZ measures 116 x 84 x 81 mm with a weight of 413 grams, while the Panasonic LZ20 is slightly larger at 120 x 76 x 80 mm and heavier at 499 grams. Notably, the Olympus's marginally more compact footprint paired with a lower mass makes it more conducive for extended handheld use and travel photography where form factor and comfort are decisive. Both cameras employ an SLR-like bridge style, facilitating a firm grip and manual control dial access.

From the top view:

The Olympus model integrates an electronic viewfinder (EVF), a critical feature missing on the Panasonic which relies solely on its LCD screen. The Olympus’s EVF delivers a framing option in bright environments and for more precise composition, albeit with moderate resolution and coverage. Panasonic's larger 3-inch LCD (vs. 2.7-inch on Olympus) boasts superior resolution (460k vs 230k dots), improving live view clarity and detail preview during shooting and playback.

Ergonomically, Olympus adopts a traditional control layout allowing for manual exposure modes (shutter/aperture priority and full manual), while Panasonic limits such granular control, although it retains a dedicated manual mode. The Olympus’s inclusion of shutter and aperture priority modes offers advanced users more creative flexibility.

Sensor and Image Quality: Evaluating the Foundations of Visual Output

Central to any camera’s imaging capacity is its sensor technology and associated processing pipeline.

Both cameras deploy a 1/2.3-inch CCD sensor (6.08 x 4.56 mm), a standard size typical for bridge cameras in their class. The Olympus has a nominal resolution of 12 megapixels (3968 x 2976), while the Panasonic pushes this to 16 megapixels (4608 x 3456). However, pixel count alone does not translate directly to superior image quality.

Technical Insight: CCD sensors are known for good color rendition and relatively low noise at base ISOs, but at elevated sensitivities, their noise characteristics deteriorate faster than CMOS sensors. Given both cameras are CCD-based, users can expect similar tonal gradation but limited detail retention in shadows under challenging lighting.

The Olympus supports a native ISO range of 64 to 6400, whereas the Panasonic's base ISO starts at 100, maxing out at 1600 natively but expandable up to 6400. Notably, tests indicate the Panasonic’s higher megapixel count can aggravate noise at high ISOs, while the Olympus's lower pixel density could yield marginally better shadow preservation and dynamic range, although neither performs well in low light compared to more modern sensor types.

Neither camera supports advanced RAW processing in an extensive fashion. The Olympus offers RAW support, beneficial for post-processing latitude, while Panasonic omits RAW capture altogether, limiting flexibility to JPEG editing.

Autofocus and Focusing Systems: Speed, Accuracy, and Versatility

For action, wildlife, and street photography, autofocus (AF) systems are mission-critical.

The Olympus SP-590 UZ employs a contrast-detection AF system with multi-area AF, but lacks continuous AF and face or eye detection. The Panasonic improves with continuous AF and face detection, utilizing a nine-point contrast-detection AF array that assists in tracking moving subjects. However, neither camera includes phase-detection AF modules, which limits AF speed and reliability, especially in low-contrast or low-light scenarios.

Olympus requires manual focusing for macro work starting at 1 cm, a notably impressive near-focus distance given its zoom range. The Panasonic’s macro capabilities extend only to 2 cm.

In practical usage, the Olympus’s AF can be sluggish and sometimes struggles with precise locking during telephoto reach, reflecting the limits of CCD imaging sensors and older AF algorithms. The Panasonic’s face detection offers an advantage for portrait and casual shooting, but continuous AF performance is modest, particularly for fast-moving subjects like sports or wildlife.

Lens and Zoom Performance: Reach, Aperture, and Stabilization

The two cameras’ defining feature is their superzoom capability:

The Olympus offers a 26x optical zoom with a wider initial aperture of f/2.8 at wide angle, aiding low-light and depth-of-field control. The Panasonic’s 21x zoom starts slightly wider at 25mm equivalent but quickly narrows aperture to f/5.8 on telephoto.

Optical image stabilization (OIS) systems are integrated into both models. Olympus applies its proprietary stabilization mechanism, noticeably effective during telephoto zoom and low shutter speeds, beneficial especially without tripod support. Panasonic’s OIS works similarly but without the same reputation for efficacy, occasionally requiring higher ISO or shutter speeds to counteract shake.

In macro photography, Olympus’s extremely close focus (1 cm) combined with a reliably fast aperture at wide angle gives it an edge for detailed close-ups. Panasonic’s 2 cm minimum focusing distance and slower aperture hinder fine macro resolution and shallow depth effects.

Viewfinders, Screens, and User Interface: Composition Tools and Operational Control

Imaging technology aside, the user interface and viewfinder options govern shooting efficiency.

The Olympus provides an electronic viewfinder (EVF) alongside the rear LCD. This permits better composition in bright environments where rear LCD visibility suffers, a common limitation for daylight shooting on LCD-only cameras like Panasonic. The relatively low EVF resolution, however, limits precision framing and manual focusing ease.

The Panasonic's 3-inch, 460k-pixel TFT LCD offers superior live-view sharpness and a more immersive real-time preview than Olympus’s smaller, lower-resolution screen. However, its lack of an EVF reduces adaptability under intensive shooting conditions.

Olympus’s button and dial layout supports manual exposure, shutter priority and aperture priority modes, and includes an exposure compensation dial, facilitating more precise control for experienced users. Panasonic’s fewer controls and absence of shutter priority mode constrain creative exposure management - an important consideration for photographers accustomed to nuanced control.

Burst Rate and Shutter Speed Range: Capturing the Moment

Rapid sequences and exposure range are vital for sports and wildlife photography.

Olympus markedly outperforms Panasonic in frame rate, offering 6 frames per second, suitable for capturing fast action sequences - albeit at limited buffer depths and with autofocus locked between frames. Panasonic’s slow 1 fps continuous shooting is insufficient for dynamic subjects.

Both cameras provide shutter ranges from 15 seconds to 1/2000 sec, accommodating low-light long exposures and freezing motion respectively, though neither offers electronic shutter capabilities or silent shutter modes.

Video Capabilities: Resolution, Formats, and Utility for Hybrid Use

Bridge cameras frequently serve hybrid use cases, blending stills and video capture.

While Olympus supports only VGA resolution at 30 fps, Panasonic delivers HD 720p at 30 fps - a significant improvement in video quality relevant for casual recording. Neither camera supports advanced video codecs (e.g., H.264), external microphones, or HDMI output (Panasonic lacks HDMI). Olympus includes HDMI port, offering limited external display connectivity.

Neither has in-body microphone or headphone jacks, restricting audio monitoring and input options. Both rely on Motion JPEG for video storage, which is inefficient by modern standards but common for cameras of their vintage and sensor generation.

Battery Endurance and Storage Flexibility: Practical Usage Considerations

Longevity and storage compatibility influence extended shooting sessions.

The Panasonic LZ20 provides a modest claimed battery life of 380 shots per charge, utilizing proprietary rechargeable battery packs - a standard for bridge cameras.

Olympus does not specify battery life in available specs, but users typically report runtimes marginally shorter than Panasonic’s, owing to the addition of EVF usage which increases power consumption.

Storage-wise:

• Olympus SP-590 UZ: Supports xD Picture Cards, microSD cards, and internal storage.
• Panasonic LZ20: Supports SD/SDHC/SDXC cards and internal storage.

The use of xD cards on Olympus is notable; while microSD is more universal, xD card support may limit options and increase costs. Panasonic’s SD card use aligns with industry standards and offers wider card selection and better compatibility.

Durability and Weather Resistance: Environmental Readiness

For outdoor and travel photographers, resistance to dust, moisture, and physical shock is indispensable.

The Olympus SP-590 UZ claims environmental sealing but does not provide certification for waterproofing, dustproofing, shockproofing, or freezeproofing. Panasonic LZ20 lacks environmental sealing entirely.

Given their bridge camera category and lightweight plastic builds, both models are better suited to controlled environments or protected outdoor use. Olympus's marginal sealing gives it a slight edge in inclement weather conditions but should not be considered rugged.
