When evaluating compact superzoom cameras aimed at enthusiasts who demand portability with considerable zoom reach, Panasonic’s Lumix series frequently emerges as a contender. The Panasonic Lumix DMC-SZ10 and Lumix DMC-ZS35 (also known as TZ55) are two such offerings from the mid-2010s, targeting users who prioritize easy handling and extensive focal lengths without investing in interchangeable lens systems.

In this exhaustive comparison, we dissect these models’ design, sensor performance, optics, autofocus, video capabilities, and usability across different photographic disciplines. Drawing upon my extensive, hands-on testing experience analyzing cameras across many market segments, this article aims to equip serious enthusiasts and professionals with the nuanced understanding necessary to select the camera that best fits their specific needs and shooting environments.

Physical Design and Ergonomics: Handling Compactness vs. Control

Physical dimensions, weight, and ergonomic layout significantly influence the user experience in compact superzoom cameras, particularly for long shooting sessions and travel use.

• Panasonic SZ10: Measuring 99 x 60 x 30 mm and weighing a featherlight 177 grams, the SZ10 is exceptionally compact and pocketable. It sports a modest body size with minimalistic control layout. Its grip contours are subtle, catering primarily to casual users prioritizing portability.

• Panasonic ZS35: Larger at 107 x 62 x 32 mm and heavier at 305 grams, the ZS35 provides a more substantive feel in hand, resembling a small bridge camera rather than a point-and-shoot. This enhances stability but may slightly compromise pocketability, especially with its longer 20x zoom lens extending the front profile.

Ergonomic aspects like button placement and control intuitiveness are essential for quick operation. The SZ10 has fewer physical controls, reflecting its entry-level orientation and lack of manual exposure modes. The ZS35 presents a denser button array alongside dedicated dials enabling shutter and aperture priority, exposing manual modes crucial for creative control.

Sensor Specifications and Image Quality: CCD vs. CMOS in Small Form Factor

Both cameras utilize a small 1/2.3-inch sensor measuring 6.08 x 4.56 mm (27.72 mm² sensor area) with a 16-megapixel resolution (4608 x 3456 pixels). This sensor size is typical for superzoom compacts, balancing sufficient resolution for 4x6 prints and moderate cropping but inherently limited in noise performance and dynamic range compared to larger APS-C or full-frame sensors.

Key technical distinctions:

The SZ10’s CCD sensor traditionally produces images with slightly better color depth in ideal lighting but suffers from slower sensor readout and higher noise at elevated ISO levels. Meanwhile, the ZS35’s CMOS sensor facilitates faster data throughput, yielding improved continuous shooting rates (10 fps vs. 1.4 fps) and more effective noise reduction algorithms, especially beneficial in low-light and action scenarios.

In actual field tests, the ZS35 consistently provides cleaner images above ISO 800, with less chroma noise and superior detail retention. The SZ10’s maximum ISO of 1600 limits usability in dim conditions, resulting in visibly softer images when pushed.

For landscape and outdoor photography, dynamic range remains limited on both cameras, attributed to the sensor size and processing engine. However, the ZS35 offers exposure compensation and bracketing modes, providing more latitude for creative capture and post-processing.

Lens and Zoom Capabilities: Reach vs. Aperture Light-Gathering

An essential aspect for superzoom models is the lens system, with focal range and maximum aperture driving versatility and image quality.

The SZ10 provides a respectable 12x zoom covering an effective 24-288 mm range, suitable for general photography and moderate telephoto work. However, the ZS35’s 20x zoom stretching to 480 mm elevates its reach for distant subjects, crucial for wildlife, sports, and travel photography.

Both lenses exhibit relatively slow maximum apertures, common in compact superzoom designs, leading to compromises in low-light performance and depth of field control.

The ZS35 includes a dedicated macro focus mode with a minimum focusing distance of 3 cm, permitting close-up shots with fine detail capture - the SZ10 lacks this precision. Optical stabilization in both models effectively mitigates handshake, but the longer telephoto reach of the ZS35 amplifies the benefit of stabilization.

Autofocus System: Precision, Speed, and Subject Tracking

Autofocus (AF) performance is a pivotal factor influencing user experience across all photography genres, impacting the ability to acquire and maintain focus on subjects in varied environments.

The SZ10 features a simple AF system with only 9 focus points and no tracking capability. While adequate for static or well-lit scenarios, it struggles with moving subjects, resulting in slower and less reliable focus lock.

In contrast, the ZS35 offers significantly improved autofocus sophistication with 21 focus points and subject tracking functionality, enabling reliable focus retention on moving targets - a distinct advantage for wildlife and sports photography.

Both rely solely on contrast-detection AF, lacking phase-detection pixels found in more advanced models, which limits speed and precision somewhat in low light or fast action. However, by integrating tracking algorithms, the ZS35 mitigates these constraints and facilitates smoother focusing during continuous shooting.

Continuous Shooting and Buffer Performance: Capturing Decisive Moments

A considerable performance difference emerges when examining burst shooting capabilities.

• SZ10 delivers an extremely modest burst rate of 1.4 frames per second (fps), adequate for casual shooting but woefully insufficient for fast action photography.
• ZS35 supports a robust 10 fps burst rate, enabling capturing of action sequences, fleeting expressions, and decisive moments.

The ZS35’s burst performance stems from its CMOS sensor architecture coupled with faster processing, a critical advantage for sports and wildlife photographers requiring increased frame capture per second.

Exposure Modes and Creative Controls: Flexibility for Enthusiast and Pro Use

One of the starkest differences lies in the availability of manual exposure modes.

• SZ10 offers limited user control - lacking shutter priority, aperture priority, and manual exposure modes. Users are confined mostly to fully automatic or basic scene selections.
• ZS35 provides a comprehensive range, including shutter priority (S), aperture priority (A), and full manual (M) modes, along with exposure compensation and bracketing.

This functional flexibility empowers photographers to manipulate exposure creatively, handle challenging lighting, and work in RAW mode (note both models do not support RAW capture) or highest JPEG quality. While neither camera supports RAW output, the ZS35’s advanced exposure modes encourage a more intentional photographic approach.

Video Capabilities: From Casual Clips to Basic HD Productions

Both cameras record video, but with distinctions to consider:

The SZ10 is limited to HD 720p capture with motion JPEG, an older codec less efficient in compression and storage usage, resulting in larger files.

Conversely, the ZS35 supports Full HD 1080p video at 30 fps with MPEG-4 compression, delivering superior video quality and storage efficiency. While absence of microphone inputs on both restricts audio control, optical stabilization aids in smoothing handheld footage.

For casual video usage, the ZS35’s clearer, higher resolution video is substantially preferable.

LCD Screens and User Interface: Visual Feedback and Operation Ease

Both cameras feature a 3-inch tilting LCD panel with 460k dot resolution, facilitating flexible monitoring from shooting angles otherwise challenging for fixed displays.

The ZS35 incorporates an anti-reflective (AR) coating and TFT technology with a 180-degree tilt ability for easier composing at high and low angles. The SZ10’s screen tilts but lacks specialized coatings, impacting outdoor visibility under bright light conditions.

Neither model supports touchscreen input, a notable omission given contemporary trends toward intuitive touch-based focusing and menu navigation.

In real-world use, the ZS35’s enhanced screen improves framing accuracy and user interface interaction, especially on dynamic shoots requiring quick adjustments.
