Panasonic Lumix DMC-LZ30 vs Panasonic Lumix DMC-SZ3: An In-Depth Comparison for Practical Buyers

When it comes to choosing a compact camera with versatile zoom and decent image quality, Panasonic’s lineup from the early 2010s offers some intriguing options. The Lumix DMC-LZ30 and DMC-SZ3, both announced simultaneously in January 2013, are cases in point. They belong to similar sensor classes but target subtly different usage profiles. As someone who has tested thousands of cameras in controlled and real-world environments, I’m here to unpack their differences and help you figure out which fits your photography needs best - whether you’re a budding enthusiast on a budget or someone who appreciates optical versatility in a straightforward package.

Let’s dive into a thorough comparison, touching on every angle from sensor tech, autofocus behavior, ergonomics, photography genres, up to practical usability factors like battery life and connectivity.

Size, Handling, and Physical Layout: More Than Just Dimensions

Sizes and ergonomics set the tone of your shooting experience long before pixels come into play. Here, the two cameras differ dramatically.

The Panasonic LZ30 is a bridge-style camera with an SLR-like body. It measures approximately 124×84×92 mm and tips the scale at 552 grams - a chunky unit designed to be held with confidence, offering a substantial grip area. That’s typical for a superzoom-style camera with a long focal range, designed to inspire steady shooting with both hands.

In contrast, the Panasonic SZ3 is a compact point-and-shoot, measuring a slender 95×56×22 mm and weighing just 126 grams. Pocketable and lightweight, it’s ideal for days when you want a no-fuss setup that you can whip out instantly.

Beyond the numbers, the LZ30’s larger size means it carries more physical controls - dedicated mode dials, buttons spilling on the top plate, and a heft that tends to improve camera stability at longer focal lengths. This is where the SZ3’s form factor limits its tactile controls, making it a camera you mostly drive via simple menus and fewer buttons.

The top-view comparison underlines this: The LZ30’s controls are well spaced and thoughtfully arranged for quick access, whereas the SZ3 keeps things barebones and minimalist. For users who like manual exposure control or just need faster camera operation, the LZ30 wins on ergonomics.

If you primarily shoot handheld, tripod use notwithstanding, I prefer the LZ30’s comfy grip over the SZ3’s dainty body. But portability lovers will appreciate the SZ3’s slender silhouette, especially for travel and street photography scenarios where discretion and lightness matter.

Sensor and Image Quality: Behind the Scenes of Every Shot

Both cameras share the same sensor class: a 1/2.3” CCD sensor that outputs 16 megapixels at 4608×3456 resolution. Technically, the sensors are similar in physical size, with the LZ30’s measuring 6.17×4.55 mm (about 28 mm²) and the SZ3’s 6.08×4.56 mm (about 27.7 mm²). While minuscule by professional standards, this sensor size is typical for small-sensor compacts of that era.

CCD technology at their time was known for decent color rendition and reasonable image quality, though with limitations in high-ISO noise and dynamic range compared to more modern CMOS counterparts.

From extensive testing under controlled lighting, both cameras deliver similar baseline image quality at lower ISOs (100-400). Details are fairly crisp, with well-saturated colors appropriate for snapshot photography. Yet, the LZ30’s 35x optical zoom outruns the SZ3’s 10x zoom by a huge margin in versatility, making it a clear winner for reach and field framing.

Noise becomes very noticeable at ISO 800 and above on both cameras. The SZ3, constrained by its simpler lens design and shorter zoom range, tends to produce slightly softer images even at base ISO, likely due to lower glass complexity.

Neither camera supports RAW capture, relying solely on JPEG outputs. For users wanting post-processing flexibility, this is a limitation you must accept.

In practical terms, if you prioritize zoom range and the ability to nail faraway subjects, LZ30’s sensor-lens combo outperforms the SZ3’s. But if you’re a casual shooter content with everyday snapshots under good natural light, the SZ3 holds up its own quite well.

LCD Display and User Interface: Where Simplicity Meets Capability

Since both cameras lack electronic viewfinders, their LCD screens are your primary composition and feedback tool.

The LZ30 offers a 3” TFT LCD at 460k dots - clearly superior to the SZ3’s 2.7” and 230k-dot screen in resolution and size. This means the LZ30’s screen delivers noticeably crisper image previews and clearer menu navigation, easing usability in bright conditions.

Neither camera features a touchscreen interface, so operation relies on button navigation which, as noted above, favors the LZ30’s more plentiful physical keys.

During my field testing, zooming and checking fine focus is easier on the LZ30’s larger, clearer screen. On the SZ3, the smaller 2.7” size makes focusing precision a little tougher, especially in sunlight or complex scenes requiring critical sharpness.

Autofocus and Shooting Speed: Reaction Time and Target Tracking

Both cameras rely on contrast-detection autofocus systems, typical for compact and bridge cameras of their time. Neither employs phase-detection AF or hybrid systems, which impacts speed and accuracy for subjects in motion or low contrast.

The SZ3 lists 23 AF points (although exact details and AF cross-type points are unclear) and supports contrast detection with multi-area and center AF modes. The LZ30 is less clear on exact AF points, but contrast detection with face detection is standard.

In practice, both cameras provide slow AF acquisition compared to modern standards. The continuous AF mode handles minor movement but struggles to keep pace when subjects change speed suddenly.

One key observation: the LZ30’s longer lens and image stabilization (optical) provide more flexibility for handholding telephoto shots, but at the cost of slightly slower AF lock times near the long end.

Continuous shooting rates are similarly modest at ~1 fps, geared more for casual capture than action or sports.

Photography Genres: How They Perform Across Different Styles

How do these cameras fare for various popular photography types? Here’s my practical take drawn from hands-on field and lab tests.

For a more visual breakdown, see the genre-specific performance scores.

Lens and Zoom: The Heart of Their Difference

The LZ30 boasts a 25-875 mm equivalent focal range - a massive 35x zoom, which I found remarkable for such a compact-ish bridge camera. This zoom range provides cropping flexibility that few cameras in the 2013 budget segment could match. For someone eager to explore subjects at a distance, from birds to architectural details, this matters.

The SZ3's lens spans a more typical 25-250 mm equivalent (10x zoom) - still pretty versatile but much less reach. This inherently limits telephoto creativity but contributes to its smaller size and simpler optics.

Both lenses have moderately fast apertures at the wide end (F3.0 on LZ30 and F3.1 on SZ3) but narrow down considerably when zoomed in (F5.9). This limits low-light performance modestly, especially at long focal lengths, although optical stabilization helps compensate.

For those who prize zoom as a deciding factor, LZ30 delivers hands-down better value and creative scope.

Battery Life and Practical Usage: Powering Your Shoot

Here’s where their design philosophies become clear.

The LZ30 uses 4x AA batteries. This is a double-edged sword - on one hand, AA batteries are widely available and can be swapped in an emergency anywhere. On the other, they add bulk and weight, and the average battery life is around 380 shots per set. My experience shows that using high-quality NiMH rechargeables can improve this, but it’s still a limitation compared to the convenience of native rechargeable batteries.

The SZ3 uses a proprietary battery pack with an average life of about 250 shots. This cramped battery life and reliance on a proprietary charger make it less convenient for extended shooting. But the overall device is lighter and more travel-friendly.

Depending on whether you value battery universality or compactness, your preference may sway.

Storage, Connectivity, and Additional Features

Both cameras rely on SD/SDHC/SDXC cards with a single card slot, which is standard.

Neither camera offers wireless connectivity (Wi-Fi, Bluetooth, NFC) or GPS. Modern standards have shifted to include these, but for the time, this was acceptable.

Video is limited to 720p at 30fps in Motion JPEG format. No external microphone or headphone ports further limit video enthusiasts.

Real-Life Samples: Comparing Image Results

Seeing is believing; here’s a sample gallery showing images shot side by side in controlled lighting and outdoor conditions.
