Let’s begin by establishing their physical presence and handling characteristics.

Feeling the Difference: Size, Ergonomics, and Controls

When evaluating cameras, one of the first tactile impressions comes from physical size, build, and control layouts - elements that influence comfort and intuitive operation.

• Canon A3100 IS: Measuring a compact 97 x 58 x 28 mm and weighing a mere 165g, the A3100 IS is among the lightest in its class. Its moderate pocketability makes it an attractive grab-and-go option, particularly for users prioritizing portability. The diminutive size, however, results in relatively diminutive buttons and limited tactile feedback, which may hinder those accustomed to more manual control.

• Panasonic LX3: Slightly larger at 109 x 60 x 27 mm and weighing 265g, the LX3 trades off pocket ease for enhanced ergonomics. The handgrip is more pronounced, and controls feel robust and satisfyingly clicky. This allows for better one-handed operation, appealing to photographers who value precision and manual adjustments.

Examining the top view reveals important nuances.

• The LX3’s dedicated mode dial includes manual exposure, aperture priority, shutter priority, and program modes, catering to advanced users requiring exposure flexibility. The Canon A3100 IS, by contrast, offers no manual exposure modes - users rely solely on fully automatic or scene presets, limiting creative control.

In summary, ergonomically and control-wise, the LX3 substantiates its higher price point with superior handling and control layout, lending itself better to enthusiasts seeking expansive manual control; the A3100 IS leans into entry-level simplicity and compact convenience.

Sensor Technology and Image Quality: The Heart of the Matter

Strictly technical comparisons begin with sensor size, resolution, and image processing, which largely dictate the foundational image quality achievable by any camera.

• The Canon A3100 IS houses a 1/2.3” CCD sensor (6.17 x 4.55 mm, 28.07 mm²) with 12 megapixels resolution. While decent for casual snaps, this sensor size inherently limits image quality particularly in low light, exhibiting higher noise levels at ISO settings above 400.

• The Panasonic LX3, however, integrates a larger 1/1.63" CCD sensor (8.07 x 5.56 mm, 44.87 mm²) at 10 megapixels resolution. Despite fewer pixels, the larger sensor facilitates bigger photosites, resulting in superior dynamic range, reduced noise, and richer color rendition. DxOMark scores reflect this, with the LX3 achieving a color depth of 19.6 bits and dynamic range approximating 10.8 EV, versus the untested yet traditionally lower metrics of the A3100 IS.

Both share CCD technology typical of their era, known for excellent color accuracy and natural tonal gradations but lag behind modern CMOS sensors in speed and high ISO performance.

Concerning anti-aliasing, both cameras deploy optical low-pass filters to minimize moiré, which slightly softens image sharpness but ensures artifact-free results in general usage.

The practical implication? The LX3’s sensor delivers cleaner images with more detail retention in shadows and highlights, especially evident in challenging lighting, while the Canon’s smaller sensor is best suited to brightly lit situations and casual shooting.

LCD and User Interface: Framing the Shot

After grasping sensor strengths, the ability to visualize and adjust compositions on-screen is crucial.

• The A3100 IS sports a modest 2.7-inch fixed LCD with 230k pixel resolution, adequate for framing and playback but limited in fidelity for critical assessment of focus or exposure. The fixed, non-touch interface restricts navigational fluidity, and there is no live histogram or advanced overlay support.

• In contrast, the LX3 features a larger 3-inch fixed LCD boasting 460k pixels, nearly doubling the pixel count, resulting in crisp, more vibrant displays. While still non-touch, the interface design is more functionally oriented, with clearer menus and real-time exposure data assists that empower manual shooters, reinforcing its appeal to enthusiasts.

Neither camera includes electronic viewfinders, meaning reliance on the LCD or composing at arm’s length. This may affect usability in bright daylight, where LCD visibility is hampered, but the LX3’s brighter screen provides a tangible advantage.

Lens Characteristics: Versatility and Optical Quality

Both models feature fixed zoom lenses; however, they target different focal lengths and apertures, impacting their versatility.

• Canon A3100 IS: 35-140 mm equivalent (4x zoom), aperture range F2.7 (wide) to F5.6 (telephoto). The longer zoom range favors casual telephoto shots like portraits and distant subjects but compromises low-light speed and bokeh quality at the longer end.

• Panasonic LX3: 24-60 mm equivalent (2.5x zoom), aperture F2.0-2.8. The wider angle is suitable for landscapes and street photography, with an impressively bright maximum aperture throughout the zoom range allowing superior subject isolation and low-light capabilities.

Macro focusing is markedly better on the LX3, down to 1 cm versus 3 cm on the Canon, facilitating detailed close-ups with higher magnification - a decisive advantage for macro enthusiasts.

Autofocus Performance: Speed, Accuracy, and Reliability

Professional and enthusiast photographers often demand quick and precise autofocus (AF) systems.

• The Canon A3100 IS uses a basic 9-point contrast detection AF system, limited to single AF mode only (i.e., no continuous AF, tracking, or face detection). While sufficient for static subjects in bright conditions, it tends to hunt slowly in low light or with moving subjects, with an average acquisition time exceeding 0.5 seconds.

• The Panasonic LX3 employs a contrast-detection AF system too, though with slight algorithmic enhancements, allowing bursts of up to 3 fps in continuous shooting. It lacks face- or eye-detection autofocus but can acquire focus steadily within approximately 0.3 seconds under optimal conditions. However, neither camera supports AF tracking or advanced subject recognition technologies typical of later mirrorless cameras.

For wildlife, sports, or fast-paced street shooting, neither camera offers competitive autofocus speed or tracking. However, manual focus on the LX3 compensates for some shortcomings, affording precise control unavailable on the Canon.
