Panasonic LZ40 vs Sony RX10

Bridging the Zoom Divide: Panasonic LZ40 vs. Sony RX10 Hands-On Comparison

As someone who has tested thousands of cameras over the last 15 years - from tiny compacts to pro-grade monsters - I’m always drawn to superzoom bridge cameras because of their promise to cover a lot of ground without switching lenses. Today, I’m turning the spotlight onto two cameras from prominent manufacturers but with decidedly different approaches: the Panasonic Lumix DMC-LZ40 and the Sony Cyber-shot DSC-RX10. Both are SLR-style bridge cameras announced within months of each other in 2014, but targeting distinct user segments and price points.

I spent extensive time shooting side-by-side with both cameras, pushing them through portrait, landscape, wildlife, and video scenarios, among others. I’ll share key technical insights and practical impressions, backed by comprehensive testing methods, to help you decide which might suit your photography goals best.

First Impressions: Size, Ergonomics, and Build

Handling cameras often reveals much more than specs alone. The Panasonic LZ40 is the more compact, lightweight option designed with casual enthusiasts in mind, while the Sony RX10 projects professional ambition with robust construction and a heftier feel.

The Panasonic’s dimensions (126 x 87 x 94 mm) and weight (~524 g) lend it portability and ease for travel photography or quick street grabs. It truly feels like a modern point-and-shoot scaled up with a massive zoom range.

In contrast, the Sony RX10’s size (129 x 88 x 102 mm) and heft (813 g) are closer to an entry-level DSLR. This affords better balance when mounting the fast, fixed 24-200mm f/2.8 lens, which is notably larger and heavier than Panasonic’s zoom.

Looking closer at controls, the RX10 offers a traditional DSLR-style layout with dedicated dials for shutter speed, aperture, and exposure compensation - boasting a top screen for quick status checks. The LZ40’s interface is sleeker but simplified, less inviting for manual mode aficionados.

My testing confirmed the RX10’s physical robustness and tactile feedback foster quicker adjustments on the fly - ideal for professionals needing reliable, precise handling. Conversely, the LZ40 feels more beginner-friendly but sacrifices some control granularity.

Sensor Technology and Image Quality – A Stark Contrast

When evaluating image potential, sensor size is a cornerstone metric. The Panasonic LZ40 uses a 1/2.3-inch CCD sensor (6.17 x 4.55 mm), considered small for today’s standards, while the Sony RX10 boasts a much larger 1-inch BSI CMOS sensor (13.2 x 8.8 mm).

From a raw performance standpoint:

• Panasonic LZ40: 20 MP resolution on a tiny sensor means smaller photosites, leading to higher noise levels, limited dynamic range, and a tendency toward blown highlights or muddy shadows in challenging light. The CCD sensor imparts decent color but struggles beyond ISO 400-800.

• Sony RX10: Also 20 MP but with larger sensor area translates to richer detail, far more latitude in shadows and highlights, and significantly improved high ISO performance. The BSI-CMOS design excels in low light and enables finer color gradation.

For image quality testing, I used standard ISO range subject shots under controlled studio and outdoor lighting to chart noise and dynamic range curves, plus real-world landscape and portrait samples.

The RX10’s superiority in retaining fine texture and delivering punchy yet natural colors was clear. In muted tones - faces, skies, foliage - the RX10 handled subtle differentiations with grace, while the LZ40 often flattened these into less nuanced output.

The Lens: Zoom Range and Aperture Trade-offs

Panasonic’s LZ40 sports an extraordinary 42x zoom spanning 22-924 mm equivalent focal lengths, eclipsing almost any bridge camera in sheer reach. It’s a powerful selling point for travelers and wildlife shooters on a budget.

Sony’s RX10 is more restrained at 8.3x zoom, 24-200 mm equivalent, but the story lies in its consistent f/2.8 aperture across the zoom range - a rarity and a huge advantage.

The wide maximum aperture means the RX10 can deliver creamy bokeh for portraits and maintain impressive low-light brightness throughout the zoom. Panasonic’s variable f/3.0-6.5 aperture means the lens closes up dramatically past the mid-zoom, impacting exposure and depth of field control.

Benefitting my practical tests, the RX10 created smoother background separation and sharper subject isolation in portrait scenarios - vital for skin tone rendition and expressive bokeh. Panasonic’s LZ40, although offering macro focus down to 1 cm and incredible reach, struggled to separate subjects cleanly due to narrower apertures and smaller sensor blur potential.

User Interface and Screen Visibility

Both cameras feature 3-inch LCD screens, but their designs and resolutions differ considerably, affecting usability.

The Panasonic LZ40 uses a fixed 460k-dot TFT screen - adequate for daylight framing but limited in detail and flexibility. No touchscreen or articulating functionality means I often found composing from awkward angles challenging, especially for candid shots.

The Sony RX10 employs a tilting 1.29M-dot WhiteMagic screen, which greatly enhances visibility in bright conditions and allows over/underhead shooting. This tilting mechanism is invaluable for landscapes on uneven terrain or for street photography when you want to maintain inconspicuousness.

Additionally, the RX10 includes a high-resolution electronic viewfinder (EVF) with 0.7x magnification and full 100% coverage, improving shooting stability and composition precision - a feature lacking entirely in the LZ40.

Autofocus and Speed – Chasing Moments

The Panasonic LZ40’s autofocus system uses contrast detection only, with 9 focus points and face detection. While it is effective in good light, its locking speed and tracking capabilities falter in dynamic scenes.

Sony’s RX10 features a more refined contrast-detect AF system with 25 points, selective AF area modes, and face detection. Despite lacking phase detection, it delivers quicker, more reliable autofocus performance during both single-shot and continuous shooting.

In real-world wildlife and sports shooting tests, RX10’s burst rate maxed at 10 fps eased capturing fleeting action, while the LZ40 limped at a mere 1 fps, making it too slow for rapid sequences.

Shooting Across Genres: Who’s Best Where?

Now, let’s dig into how these two cameras stand up across common photography disciplines, informed by extensive fieldwork.

Portrait Photography

Portraits demand accurate skin tone reproduction, subject-background separation, and reliable eye detection for focus.
