Panasonic LX3 vs Sony W710: A Hands-On Comparative Review for Serious Photographers

Choosing the right compact camera is often a balancing act between image quality, handling, and budget. Today, I’m putting two beloved small sensor compacts head-to-head: the Panasonic Lumix DMC-LX3, a classic 2008-era enthusiast’s compact, and the more recent Sony Cyber-shot DSC-W710, which arrived in 2013 targeting casual users. Though separated by half a decade and quite different in design philosophy, their specs put them in an interesting dialogue about what small sensor compacts can offer. Drawing from my extensive hands-on testing experience, I’ll break down what each camera delivers and, importantly, where they fall short across various photographic disciplines.

Digging Into The Designs: Ergonomics, Controls, and Usability

The first noticeable difference between these two cameras emerges when you pick them up. The Panasonic LX3 feels notably more substantial and solid in hand - a welcome attribute for photographers who value tactile control. Measuring 109mm x 60mm x 27mm and weighing 265g, it’s a compact camera with serious photographer appeal, featuring classic manual dials and buttons that invite hands-on tweaking. It was designed by Olympus engineers who also contributed to the Olympus E-PL1, and their commitment to a thoughtful button layout shows.

Conversely, the Sony W710 is significantly lighter and smaller - just 97mm x 55mm x 20mm and 114g - making it an ultra-portable point-and-shoot. Its touchscreen adds some modern flair, yet manual controls are entirely absent. The camera leans heavily on auto modes and simplified exposure settings, reflecting its aimed-at casual shooters.

Look at the top view of each camera, and this difference in function-first versus portability-first becomes obvious. Panasonic offers dedicated control rings and shutter speed dials that matter in fast-paced shooting environments, while Sony presents a minimalistic, button-light layout.

Ergonomics verdict: For enthusiasts craving manual exposure control and physical dials, the LX3 wins hands down. If pocketability and ease-of-use are your priorities, consider the W710.

Heart of the Camera: Sensor Specifications and Image Quality

At the core of any camera’s capability are the sensor and image processor pairing. Both cameras use CCD sensors - older technology even in their era - but with significant differences in size and resolution.

• Panasonic LX3: 1/1.63" sensor measuring 8.07 x 5.56mm, with an effective resolution of 10 MP. This yields a sensor area of about 44.9mm². The sensor supports RAW capture, an enthusiast-centric feature allowing for extensive post-processing flexibility.

• Sony W710: Smaller 1/2.3" sensor (6.17 x 4.55mm), with 16 MP resolution and a sensor area of 28.1mm². No RAW support.

While the W710 sports a higher nominal megapixel count, the smaller sensor and significant pixel density compromise pixel quality and low-light performance. From my testing, the LX3’s larger pixels deliver cleaner images, less noise at ISO 400 and 800, and superior dynamic range. Panasonic’s sensor exhibits a measured color depth of 19.6 bits and a dynamic range of 10.8 EV, according to DxO Mark benchmarks - a testament to its raw image quality pedigree.

The Sony W710, with no DxO data available, can’t match this performance. ISO sensitivity maxes out at 3200 native but noise levels rise sharply beyond 400 ISO. The megapixel advantage is somewhat superficial - it produces sharper images only in bright conditions, but those benefits vanish in anything less than ideal light.

Image quality verdict: Panasonic LX3 offers the better sensor for serious image quality, especially if you plan to shoot RAW or under variable lighting conditions. Sony W710 is adequate for casual daylight snapshots but struggles beyond.

Exploring LCD Screens and User Interfaces

The interface is often a make-or-break factor for compact cameras, especially when speed of operation and feedback are critical.

The LX3 sports a fixed 3-inch LCD with a resolution of 460k dots, larger and sharper than the Sony’s 2.7-inch, 230k dot touchscreen. While the W710’s touchscreen is a novelty for its class, in practice, its touch responsiveness is sluggish, making quick manual focusing or exposure adjustments more of a chore than a convenience. Plus, the LX3’s larger screen better displays composition and detail, crucial for reviewing images on the fly.

Neither camera has an electronic viewfinder, limiting composition choices in bright sunlight.

Autofocus Performance in Real-World Shooting

Autofocus is mission critical in everyday photography, even more so in genres like sports or wildlife.

• Panasonic LX3 relies on contrast detection AF with single AF mode only; no continuous autofocus or tracking support.
• Sony W710 features contrast detection plus rudimentary AF tracking and face detection, plus touch AF capability.

I performed comparative tests focusing on subjects in motion. In static portraits or controlled landscapes, the LX3’s AF locked reliably - albeit with a slight lag and hunting evident in low light. The Sony’s face detection and continuous AF tracking made it easier to follow moving subjects, though the system sometimes missed focus in low contrast or dim environments.

However, the LX3’s faster lens aperture (f/2.0 at wide angle) gives it a slight edge helping autofocus and creating shallow depth of field effects.

The Lens: Aperture, Zoom, and Macro Capabilities

The Panasonic LX3 sports a fast, versatile 24-60mm equivalent f/2.0–2.8 Leica-branded zoom lens. Its wide aperture at the short end is impressive for a compact and enables cleaner backgrounds and better low-light shooting. The macro minimum focus distance of 1cm is remarkable, allowing true close-up photography - something I exploited to capture fine flower details with excellent sharpness.

In contrast, the Sony W710 has a longer 28-140mm equivalent zoom - greater telephoto reach but much slower aperture, ranging f/3.2 to f/6.5. Macro focusing distance stands at 10cm, limiting extreme close-ups although it still performs well for casual macro shots.

In practice:

• Panasonic LX3 lens offers greater creative control, better bokeh, and superior close focusing.
• Sony W710 is more of an all-rounder zoom for snapshots but not a precision instrument.

Versatility in Different Photography Genres

Let’s see how each camera performs across popular photographic disciplines:

Portraits: Skin Tones and Bokeh

Portraits demand nuanced skin tone reproduction and pleasing background blur.

• The LX3’s larger sensor and bright f/2 lens combine to produce smoother gradients and selective focus, key to professional-looking portraits.
• The Sony W710’s smaller sensor and slower lens render flatter images with less subject separation, limiting artistic expression.

Neither has advanced eye detection autofocus found in modern cameras, but the W710’s face detection helps casual users compose better portraits.

Landscapes: Resolution and Dynamic Range

For landscapes, resolution, wide-angle coverage, and dynamic range matter profoundly.

• Panasonic: 10 MP at 24mm equivalent wide angle covers most typical landscapes. The improved dynamic range captures bright skies and shadow detail better.
• Sony: 16 MP at wider telephoto zoom covers framing variety, but smaller sensor impairs dynamic range and color fidelity.

Weather sealing? Neither camera offers this, so outdoor use requires caution.

Wildlife and Sports: Autofocus Speed and Burst Rates

Wildlife and sports photography push cameras to track subjects quickly.

• LX3 max burst is 3 fps, autofocus limited to single AF. Not ideal for fast action.
• W710 shoots only 1 fps, also no continuous AF.

Neither is a real contender for serious wildlife or sports. Professionals will find their speed and AF inadequate.

Street Photography: Discretion and Portability

The W710’s extremely light and compact form factor scores well here; its discreet design and relatively quiet operation lend to candid shooting. The LX3, though bigger, remains pocketable and offers manual control that street photographers often value.

Macro Photography: Focusing Precision and Magnification

The LX3’s 1cm macro focus distance is exceptional and produces impressive magnification. The Sony’s 10cm minimum distance relegates it to casual macro work only.

Night and Astro Photography: High ISO and Exposure Options

Both cameras top out at ISO 3200/6400 but noise quickly degrades images at these settings, especially on the smaller Sony sensor. Neither supports dedicated astro modes or bulb exposure. Low-light shooting is challenging on both, though the LX3's faster lens helps.

Video Capabilities: Resolution and Stabilization

Both cameras offer 720p HD video, but:

• Panasonic: 1280 x 720 at 24 fps, optical image stabilization, no microphone inputs.
• Sony: 1280 x 720 at 30 fps, optical stabilization, and supports MPEG-4 and AVCHD.

Neither camera supports advanced video features but the Sony’s more modern codec support might be a plus for casual videographers.

Travel Photography: Battery Life, Size, and Versatility

Battery life figures (240 shots W710, unknown LX3) show neither excels for marathon travel days without spares. The Sony’s smaller size and lower weight make it the better companion for minimalist travelers; the LX3 offers more creative flexibility for the intrepid enthusiast.

Professional Work: File Formats and Workflow

Panasonic’s RAW support, manual controls, and native exposure modes mark it as a serious tool for professionals seeking compact backup or secondary camera use. Sony W710’s lack of RAW and limited manual options exclude it from many professional workflows.

Build Quality and Weather Resistance

Neither model offers environmental sealing, dustproofing, or ruggedization. The LX3’s metal body feels more premium, while the Sony’s plastic shell suits casual everyday carry.

Connectivity and Storage

Both cameras depend on USB 2.0 for data transfer and support SD card slots, but the W710 adds Memory Stick compatibility for legacy Sony users. Wireless or GPS functions are absent from both models.

Pricing and Value Proposition

Launched at about $449 for the LX3 and $90 for the W710, price points significantly influence who should consider which model. The LX3’s premium level shows in build and image quality, demanding a steeper price - and newer used models still hold value.

The W710 trades sophistication for bargain-basement pricing, suitable for novices or super-lightweight travel.
