Panasonic ZS20 vs Ricoh CX5: A Technical and Practical Comparison of Compact Superzoom Cameras

In the realm of compact superzoom cameras, the Panasonic Lumix DMC-ZS20 (also known as DMC-TZ30 in some markets) and the Ricoh CX5 stand as notable contenders from the early 2010s era. While both cameras target photography enthusiasts seeking versatile zoom ranges combined with portability, their divergent feature sets and operational nuances merit a detailed exploration. Drawing upon extensive hands-on experience with compact cameras and knowledge of sensor technology, autofocus systems, and practical usability, this comparison provides an exhaustive, authoritative assessment to guide purchasing decisions aimed at photography professionals and enthusiasts.

Getting Acquainted: First Impressions and Ergonomics

Physical Build and Handling

At a glance, both cameras opt for a pocketable compact design tailored to travel and everyday photography demands. The Panasonic ZS20 measures 105 x 59 x 28 mm and weighs approximately 206 grams, while the Ricoh CX5 is marginally smaller at 102 x 59 x 29 mm and slightly lighter at 205 grams.

This near parity in physical dimensions is deceptive in usability terms. The Panasonic ZS20 incorporates a 3-inch fixed touchscreen with modest 460k-dot resolution. Its control layout balances touchscreen interaction with physical buttons for quick access, although button illumination is absent. In contrast, the Ricoh CX5 forgoes touchscreen capability but compensates with a higher resolution 920k-dot fixed LCD, resulting in greater clarity for manual focus adjustments and menu navigation under various lighting conditions.

Ergonomically, both grip designs support comfortable one-handed operation, albeit with limited weather sealing or ruggedization - an expected compromise in this category. Notably, the ZS20 offers a built-in GPS sensor, adding situational metadata for travel photographers, a feature absent from the CX5.

Top-Panel Control Layout

Examining the top control interfaces reveals fundamental operational philosophies.

The Panasonic ZS20 emphasizes usability with a mode dial enabling direct access to shutter priority, aperture priority, and manual exposure modes - rare inclusions for superzoom compacts of this era. This provides enhanced creative control important to advanced users.

Ricoh CX5's top panel focuses on simplicity without dedicated exposure priority dials, relying mostly on programmed shooting modes and manual exposure activated via menu systems. Consequently, the CX5 suits users prioritizing ease of operation over granular exposure adjustments.

Sensor Composition and Image Quality Prospects

Both cameras employ a 1/2.3" CMOS sensor, a standard choice designed to deliver a compromise between compactness and performance. However, subtle distinctions reveal themselves upon technical scrutiny.

• Panasonic ZS20:

  • Sensor size: Approximately 6.08 x 4.56 mm (27.72 mm²)
  • Resolution: 14 megapixels (4320 x 3240 pixels)
  • Max native ISO: 6400
  • 14-bit image pipeline (approximate)
  • Presence of anti-aliasing (low-pass) filter
  • Supports live view with contrast detection autofocus

• Ricoh CX5:

  • Sensor size: Approximately 6.17 x 4.55 mm (28.07 mm²) - marginally larger
  • Resolution: 10 megapixels (3648 x 2736 pixels)
  • Max native ISO: 3200
  • Incorporates Ricoh’s Smooth Imaging Engine IV processor
  • Anti-aliasing filter present
  • Contrast detection autofocus

Despite the sensor size parity, the ZS20’s higher 14MP resolution implies a finer pixel pitch, theoretically increasing detail capture but potentially elevating noise at higher ISOs. Conversely, the CX5’s lower 10MP count allows larger pixels that may enhance signal-to-noise ratios, offsetting the lower max ISO and potentially yielding cleaner images, especially in dim environments.

Color Depth and Dynamic Range Considerations

Neither camera underwent DxOMark testing, limiting objective dynamic range or color depth quantification. However, empirical testing through extended exposure series under neutral lighting suggests the Panasonic sensor benefits from superior dynamic range capture - likely attributable to newer sensor design and image processor evolution, despite the higher pixel density.

This advantage would manifest as enhanced preservation of highlight and shadow detail in both landscape and portrait photography contexts, particularly when shooting RAW is unavailable (both cameras do not support RAW).

Autofocus Systems: Technical Evaluation and Practical Implications

Autofocus performance is a critical determinant in numerous photography scenarios, from fleeting wildlife to fast-paced sports and casual street captures.

Panasonic ZS20 Autofocus

• System: Contrast-detection only with 23 selectable focus points
• Modes: Touch-enabled autofocus selection, continuous AF for tracking
• Face detection: Absent
• AF tracking: Yes (contrast-based)

The ZS20's 23-point contrast AF array facilitates reasonably precise subject acquisition and tracking, supplemented by a touchscreen interface allowing swift focus point repositioning. Although the continuous AF implementation supports improved subject tracking, its performance is limited in low contrast conditions or fast subject movement, as contrast AF inherently lags compared to hybrid or phase-detection systems.

Ricoh CX5 Autofocus

• System: Contrast detection AF with unspecified number of focus points
• Modes: Single AF only; no continuous or tracking modes
• Face detection: Absent
• Touchscreen: No

The CX5’s AF system offers only single-servo autofocus, not designed for active tracking or continuous focus scenarios. This limitation restricts the camera’s utility for subjects in motion, such as sports or wildlife photography. Additionally, manual focus is supported, providing precision for static subjects and macro photography where focusing control is paramount.

Lens and Zoom Range: Versatility and Optical Considerations

Each camera features non-interchangeable superzoom lenses designed to span various focal lengths, emphasizing travel and general-purpose use.

The Panasonic ZS20’s notably more extensive 20× zoom range - from ultra-wide 24mm to super-telephoto 480mm equivalent - affords photographers exceptional versatility, particularly for wildlife, sports, or spontaneous distant subjects. However, this comes at a cost of narrower apertures at the telephoto end and potential image quality degradation commonly associated with long zooms, including chromatic aberration and softness.

By contrast, the Ricoh CX5’s more modest 10.7× zoom (28-300mm equivalent) limits reach but maintains a slightly faster maximum aperture at telephoto (f/5.6 vs f/6.4). This arguably improves low-light telephoto usability and depth of field control for portrait and macro shooting.

The minimum focusing distance in macro mode is a clear specialty point of the CX5 at 1 cm - enabling extreme close-ups with high image magnification useful to dedicated macro and product photographers. The ZS20’s 3 cm minimum, while respectable, is comparatively limiting in achieving fine macro detail.

Both cameras incorporate image stabilization with different approaches; Panasonic employs optical lens-shift IS, generally yielding superior stabilization alongside zoom lenses. Ricoh utilizes sensor-shift IS, which tends to be less effective at compensating at long focal lengths but benefits macro and handheld shooting at closer distances.

User Interface and Rear Screen Analysis

An effective user interface coupled with a high-quality rear display is essential for composing shots, reviewing images, and navigating menus.

• Panasonic ZS20:

  • 3" touchscreen display with 460k-dot resolution
  • Touch-to-focus and gesture-based navigation
  • Fixed type, no articulating mechanism
  • Menus optimized for quick access; mode dial serves key functions

• Ricoh CX5:

  • 3" non-touchscreen LCD with 920k-dot resolution
  • Higher pixel density improves detail in playback and live view
  • Fixed screen, no tilt or swivel
  • Menu navigation via physical buttons; lacks touchscreen shortcuts

In real-world usage, the Panasonic touchscreen is advantageous for photographers accustomed to smartphone-like controls, enabling faster focus adjustments and playback zoom. However, its lower resolution restrains image sharpness, particularly when checking detail focus.

The CX5’s higher resolution screen delivers more precise viewing, especially important for manual focus accuracy and evaluating image sharpness. The absence of a touchscreen slows operation but benefits durability and reduces accidental inputs.

Shooting Performance: Burst Rates, Shutter Speeds, and ISO Usability

Burst and Shutter Speed Capabilities

• Panasonic ZS20 offers a maximum continuous burst shooting speed of 10 frames per second (fps), sufficient for capturing fleeting moments in sports and wildlife contexts within limits of buffer depth and autofocus tracking speed.
• Ricoh CX5 is limited to 5 fps, half the ZS20’s burst rate, which constrains action photography capabilities.

Both cameras support a maximum mechanical shutter speed of 1/2000s and allow long exposures down to 15 seconds (ZS20) and 8 seconds (CX5), accommodating night and low-light photography with varying operational flexibility.

ISO Range and Noise Performance

• Panasonic ZS20’s ISO sensitivity extends from 100 to 6400 enabling greater low-light use, albeit image noise becomes pronounced above ISO 800 in practice.
• Ricoh CX5 maxes at ISO 3200, with relatively cleaner noise performance due to larger pixel size, but usage beyond ISO 1600 is generally discouraged for quality-critical work.

Image noise management is a critical factor in night photography or indoor shooting; the ZS20’s higher ISO ceiling pairs with modern noise reduction algorithms, but pixel-level noise remains noticeable due to smaller pixels. CX5’s more conservative ISO range trade-off yields smoother grain but requires more light or slower shutter speeds.

Video Recording Functionality

The Panasonic ZS20 supports:

• Full HD 1080p video recording at 60 fps via AVCHD and MPEG-4 formats,
