A Tale of Two Compact Cameras: Initial Impressions and Design Philosophy

At a glance, the Panasonic ZS30 and Sony S2100 appear to cater to somewhat different demands within the compact camera space. The ZS30, announced in early 2013, sits solidly in the “small sensor superzoom” category - a compact body with an impressively long focal range - while the S2100, launched three years earlier in 2010, fits more neatly into a traditional compact camera mold with a shorter zoom range and a focus on simplicity.

Ergonomics and Handling

Physically, both cameras are pocketable, but the Panasonic ZS30 measures 105x59x28 mm and weighs 198g, slightly larger and heavier than the Sony's 98x61x27 mm and 167g. This size difference reflects the ZS30’s larger zoom lens and additional feature set. In practice, the Panasonic’s grip design and button layout feel more robust and are easier to manipulate quickly, especially in situations requiring rapid adjustments - a bonus during travel or street photography. The Sony’s more diminutive size translates to slightly improved portability but at the expense of some control and ease of use.

Sensor and Image Quality: Progressive CMOS vs. Classic CCD

The sensor is the heart of any camera, and here we see fundamental technical differences impacting image quality, dynamic range, and low-light capabilities.

Sensor Technology Overview

• Panasonic ZS30: 1/2.3" CMOS sensor (6.17x4.55 mm), 18 megapixels
• Sony S2100: 1/2.3" CCD sensor (6.17x4.55 mm), 12 megapixels

While both cameras share the same sensor dimensions, the ZS30's more modern CMOS sensor generally offers faster readout speeds and better noise performance, especially at higher ISO values. The ZS30 reaches a max ISO of 6400 natively, doubling the S2100’s maximum ISO of 3200.

Resolution and Detail

The ZS30’s 18-megapixel sensor provides higher resolution images (4896x3672 pixels), which can translate to finer detail and more cropping flexibility - a significant advantage for landscape and wildlife photographers. By contrast, the S2100’s 12-megapixel output (4000x3000 pixels) is adequate for casual prints and web sharing but less forgiving for detail-demanding workflows.

Color Depth and Dynamic Range

Though neither model has been tested by DxOMark, the CMOS sensor generally yields better dynamic range due to lower noise and higher bit depth in image processing compared to CCDs. This becomes apparent in scenes with high contrast - such as backlit portraits or bright landscapes. The Panasonic camera's pro-oriented exposure modes help further optimize dynamic range capture.

Lens and Zoom: Range, Aperture, and Practical Implications

Arguably, the most immediate differentiator is the optics. The Panasonic ZS30 boasts a 20x zoom covering 24-480 mm (35mm equivalent), while the Sony S2100’s zoom tops out at a modest 3.2x, covering 33-105 mm.

Zoom Versatility and Aperture

• Panasonic ZS30: 24-480 mm (20x zoom), aperture F3.3-6.4
• Sony S2100: 33-105 mm (3.2x zoom), aperture F3.1-5.6

The ZS30’s telephoto reach offers exceptional versatility for wildlife, sports, and travel photographers who desire close-ups from a distance without swapping lenses. The trade-off is the variable maximum aperture dropping to F6.4 at the telephoto end, leading to challenges in low light.

The Sony’s wider aperture range and shorter zoom mean it performs better in low-light conditions at the telephoto end, but its limited zoom confines its usability in certain disciplines. It excels for casual snapshots and street photography where discretion and speed matter more than focal range.

Macro Focus

In close-up work, the ZS30 can focus as close as 3 cm, outperforming the Sony’s 5 cm macro capability - an important consideration for macro enthusiasts and nature photographers who want to capture fine details without external accessories.

Autofocus, Shutter, and Shooting Experience

Autofocus speed and accuracy, shutter range, and continuous shooting rates significantly influence the camera’s usability across genres.

AF System and Performance

• Panasonic ZS30: 23 focus points, contrast-detection AF, face detection absent, continuous AF and tracking available
• Sony S2100: 9 focus points, contrast-detection AF, face detection absent, single AF only

The Panasonic’s richer AF point array and continuous AF with tracking notably improve ease of use when photographing moving subjects (wildlife, sports) or tracking in video. In contrast, the Sony’s single-shot AF is slower, better suited for static scenes or deliberate compositions.

Shutter and Burst Rates

The ZS30 offers shutter speeds from 15 seconds to 1/1200 sec, with a robust continuous shooting mode at 10 fps - impressive for a compact camera, enabling capture of fleeting moments in sports or wildlife.
