Panasonic SZ10 vs Panasonic ZS3: A Technical and Practical Comparison of Small Sensor Superzoom Compacts

In this in-depth comparison, we analyze two Panasonic small sensor superzoom compact cameras: the Lumix DMC-SZ10 (SZ10) announced in early 2015 and the older Lumix DMC-ZS3 (ZS3), also known as the Lumix DMC-TZ7, introduced in mid-2009. Both models target casual enthusiasts and travelers seeking versatile focal length ranges packed into pocketable bodies with optical image stabilization.

Despite shared brand lineage and a similar 12× zoom range, there are important distinctions in sensor resolution, autofocus capability, ergonomics, and video options. Drawing upon extensive hands-on testing experience of hundreds of similar cameras, this comparison will dissect these critical aspects and their implications for use-cases ranging from travel shoots to casual wildlife photography. Photographers considering either model will find detailed guidance grounded in real-world assessment and sensor/AF technology fundamentals.

Physical Size, Design, and Handling

A camera’s ergonomics form the foundation of the user experience, particularly for travel or street photography where portability and quick access matter. The SZ10 and ZS3 are both constructed in compact “point-and-shoot” form factors but with subtle differences affecting comfort and handling.

• SZ10 Dimensions & Weight: 99×60×30mm at 177g
• ZS3 Dimensions & Weight: 103×60×33mm at 229g

The SZ10 is noticeably lighter by about 50 grams and slimmer, reflecting modern design priorities to enhance pocketability. The ZS3's thicker profile and added weight correspond with its older build and inclusion of a fixed lens system with a slightly longer focal length at the telephoto end (300mm equivalent vs 288mm on the SZ10). This modest difference may translate into better balance or grip in some hands but at the cost of bulk.

Regarding the control layout and external interface, both cameras forgo an electronic viewfinder, relying solely on 3-inch LCD screens for framing and menu navigation. Neither has touchscreen or self-timer quick-access buttons, though they do include standard flash hotshoe alternatives incompatible with external flashes.

The SZ10 benefits from a tilting screen - a practical advantage when shooting from unconventional angles or composing selfies, which enhances flexibility in street or travel scenarios. In contrast, the ZS3’s screen is fixed, which may hinder usability in certain compositions.

In practical operation, the SZ10’s slightly reduced bulk and tilting display foreground a more versatile, ergonomic design suitable for portability-demanding applications. Conversely, the ZS3’s more substantial chassis offers a reassuring grip but may fatigue hands during prolonged handheld shooting.

Sensor Technology and Image Quality

A paramount consideration in comparing compact superzooms is sensor performance, as it directly impacts image resolution, dynamic range, and noise characteristics. Both models utilize 1/2.3" CCD sensors with a physical sensor size of 6.08×4.56mm equating to roughly 27.7mm² - typical for small sensor compacts but well behind APS-C or larger.

However, the SZ10 features a 16-megapixel sensor resolution, whereas the ZS3 offers a 10-megapixel sensor. This difference results in:

The SZ10 delivers higher native resolution, which can produce more detailed images suitable for moderate cropping and large prints. However, increasing resolution on such a small sensor can exacerbate noise, especially in low-light conditions, thereby challenging image quality.

From extensive controlled testing with similar sensor technology, the SZ10’s noise floor rises noticeably beyond ISO 800, making ISO 1600 usable only with post-processing concessions. The ZS3’s lower megapixel count coupled with a higher maximum native ISO (6400) hints at better high-ISO noise handling. However, in practice, elevated ISO settings on the ZS3 degrade images rapidly due to the older CCD sensor’s limitations and lack of advanced noise reduction algorithms available on later models like the SZ10.

Both cameras apply anti-aliasing filters to combat moiré patterns, which slightly affect sharpness but improve image fidelity in repeated patterns - a common characteristic for CCD sensors.

In terms of dynamic range - the ability to capture detail in bright highlights and dark shadows simultaneously - neither model excels due to the small sensor size and CCD architecture but the SZ10 shows marginal improvements thanks to slightly newer sensor and image processor firmware.

Special note: Neither camera supports shooting in RAW format, limiting post-capture image manipulation options. This constraint restricts their appeal for enthusiasts or professionals who rely on expansive editing workflows.

Autofocus System and Focusing Capabilities

Autofocus (AF) performance critically influences usability, especially for photographic genres involving moving subjects or rapid framing changes.

The SZ10’s 9-point AF system improves accuracy in framing subjects, complemented by face detection functionality which provides a significant advantage for portraiture and general focus reliability in people photography. The addition of continuous autofocus is also notable for tracking moving subjects in video or burst modes.

Conversely, the ZS3 offers 11 AF points but lacks face detection and continuous AF, which limits its precise focusing speed and accuracy under dynamic shooting scenarios. Its macro focusing capability down to 3 cm permits capture of close-up details uncommon in its class and era.

Despite these distinctions, both systems use contrast detection only - slow compared to phase detection AF found in advanced cameras - thus are generally suited for static or slow-moving subjects rather than fast action photography. The SZ10, with its slight improvements in AF algorithms and sensitivity, is better positioned for capturing moments requiring quick adjustments.

Burst Shooting and Shutter Performance

Burst shooting modes influence the capture of decisive moments in sports or wildlife photography. Below is the comparison:

The ZS3 offers a slightly faster burst rate (2 fps vs. 1.4 fps on the SZ10), which is marginal and unlikely to meet the demands of serious sports or wildlife photographers requiring rapid frame capture.

Relevant to long exposures, the SZ10’s minimum shutter speed going down to 8 seconds facilitates some handheld night photography without manual bulb control, whereas the ZS3’s minimum 1/60s shutter speed restricts longer exposures to tripod use.

Neither camera supports electronic or silent shutters, which limits shooting flexibility in quiet environments or scenarios requiring minimal camera shake and shutter vibration.

Image Stabilization and Macro Performance

Optical image stabilization (OIS) substantially enhances handheld shooting by compensating for camera shake and enabling slower shutter speeds.

Both cameras feature Panasonic’s standard optical image stabilization, effectively reducing blur during telephoto shots and low-light usage. Field testing reveals similar OIS efficacy on both models, with roughly 2-3 stops of compensation being realistic.

In the macro domain, the ZS3’s close focusing of 3 cm allows for capturing finely detailed images of small objects and textures, an advantage over the SZ10 which doesn’t specify macro range - likely indicating a longer closest focusing distance limiting close-up opportunities.

Macro photography benefits strongly from precise AF and stabilization to avoid motion-induced blur. Practically, the ZS3 offers more purposeful macro utility despite its older sensor.

LCD Display and User Interface

User interface design and screen quality materially affect usability during photo composition and menu navigation.

Both cameras employ 3-inch LCDs at a 460k pixel resolution, delivering clear, bright displays adequate for framing and reviewing images outdoors. However, the SZ10’s screen features tilting articulation, greatly enhancing flexibility for shooting from high or low angles, as well as enabling rudimentary ‘selfie’ compositions.

Neither camera offers touchscreen capabilities, an increasingly common convenience in later compact cameras for intuitive focusing and menu adjustments. Users of these models must rely on physical buttons and dials, the SZ10 providing a somewhat more modern interface with dedicated AF and exposure controls.

From experience, the absence of an electronic viewfinder makes bright daylight shooting challenging, as LCD glare can limit visibility, especially on the fixed screen ZS3.

Video Recording Capabilities

Compact cameras increasingly serve hybrid photo-video functions, but both models present modest video feature sets:

While both record HD 720p video at 30 frames per second, the SZ10 records in Motion JPEG format - a simple but less storage-efficient codec - whereas the ZS3 supports AVCHD Lite, offering better compression and generally higher-quality video for the same bitrate.

Neither camera supports 1080p recording or advanced video options such as external microphone input or headphone monitoring, limiting appeal for serious videographers. The OIS in both models aids handheld video shooter stability.

Overall, the ZS3 offers technically superior video compression but the SZ10’s newer processing may deliver smoother autofocus transitions when recording.

Connectivity, Battery Life, and Storage

Connectivity features support workflow efficiency, distance control, and image transfer. Battery longevity impacts session duration.

The SZ10 benefits from integrated Wi-Fi, enabling wireless image transfer and remote control via compatible apps. This feature is absent on the ZS3, which relies entirely on cable connections for data retrieval.

The ZS3 includes an HDMI port for direct playback on external displays - a feature omitted from the SZ10. This may influence users prioritizing viewing convenience.

The SZ10’s battery endurance is rated at 200 shots per charge under CIPA testing - a moderate figure consistent with compact cameras but potentially limiting day-long outings without spares. No official battery life data is available for the ZS3, though its heavier build suggests a possibly larger capacity battery yielding comparable or better endurance.
