Examining the top view of each camera reveals significant philosophical differences in user interface design:

The Olympus E-PL3 sports a dedicated mode dial, a shutter speed dial on the top right, and buttons for direct access to ISO, exposure compensation, and playback - typical of mirrorless cameras appealing to users who demand quick manual adjustments. The tilting 3-inch HyperCrystal LCD with anti-reflective coating also facilitates versatile shooting angles, albeit lacking touchscreen capabilities.

The Panasonic FS7, with no dedicated exposure modes beyond auto and limited scene presets, places more emphasis on simplicity: the power button, shutter release, zoom control, and a small, fixed 2.7-inch LCD suffice for straightforward operation but offer less flexibility for advanced users.

User interface note: While the E-PL3 demands a moderate learning curve, it ultimately rewards with granular control, favoring enthusiasts; the FS7 is ideal for those preferring an intuitive point-and-shoot experience.

Sensor and Image Quality: The Core of Photographic Performance

Sensor Size and Technology

A fundamental distinction arises in sensor technology and its implications on image quality, noise performance, and depth of field control.

• Olympus E-PL3: Four Thirds size (17.3 x 13 mm) CMOS sensor, 12 megapixels, TruePic VI image processor.
• Panasonic FS7: Compact 1/2.5-inch size (5.74 x 4.31 mm) CCD sensor, 10 megapixels.

The larger Four Thirds sensor in the E-PL3 boasts a sensor area of approximately 225 mm², nearly 9× larger than the FS7’s 25 mm². This increase translates to superior light gathering ability, resulting in better low-light sensitivity, higher dynamic range, and finer detail reproduction. Further, the CMOS sensor coupled with Olympus’s TruePic VI processor facilitates faster image readout and superior noise control.

In contrast, the FS7’s smaller CCD sensor limits its dynamic range and ISO capability (max native ISO 1600, with boosted modes up to 6400), resulting in more noise and reduced flexibility in challenging lighting. The smaller sensor also imposes a greater inherent depth of field, reducing background blur control.

Technically, Olympus’s inclusion of an antialias filter, albeit limiting micro-detail somewhat, helps prevent moiré and aliasing artifacts. The FS7 similarly features such a filter but combined with a smaller sensor resolution.

Conclusion: E-PL3 is fundamentally advantaged for photographers who prioritize image quality, especially in low light and high-contrast scenes.
