The FS25 is a small-sensor compact camera, weighing a mere 148 grams with dimensions of 97 x 58 x 22mm. Its slim body fits easily in a pocket, making it ideal for casual shooters or travelers wanting a no-fuss point-and-shoot. The fixed 29-145mm (5x optical zoom) lens covers a versatile zoom range but with a relatively modest maximum aperture of f/3.3-5.9, limiting low-light capability and depth-of-field control.

Controls are minimalistic - no manual exposure modes, no dedicated dials, and a fixed, non-touch 3-inch LCD with 230k-dot resolution.

Sony A390: More Robust DSLR Handling

By contrast, the Sony A390 is a bona fide DSLR, considerably larger and heavier at 549 grams and a bulky 128 x 97 x 86mm body. The heft translates to improved grip stability and ergonomics suited for longer sessions or more deliberate shooting. The optical pentamirror viewfinder with 95% coverage offers a classic DSLR experience, complemented by a tilting 2.7-inch LCD (230k dots).

The A390 includes a robust button layout and manual controls, including shutter and aperture priority, full manual mode, and exposure compensation - features essential to more advanced photographers.

Handling Conclusion

If you prize portability and simple operation, the Panasonic FS25’s compact form is compelling. However, if you desire manual control, stable grip for telephoto lenses, or optical viewfinder use, the Sony A390’s DSLR construction provides considerable ergonomic and functional advantages.

Sensor and Image Quality: The Core of Photography

Image quality stems largely from sensor size, resolution, and processing technology.

Sensor Technology and Resolution

• Panasonic FS25: Equipped with a 1/2.3" CCD sensor measuring 6.08 x 4.56mm and producing 12MP images at 4000x3000 pixels. Small sensor size limits low-light performance and dynamic range.
• Sony A390: Features a significantly larger APS-C-sized (23.5 x 15.7mm) CCD sensor with 14MP resolution (4592 x 3056 pixels). The larger sensor area (roughly 13x the surface) results in better noise control, higher detail, and more pleasing bokeh.

Image Processing and ISO Performance

The FS25 uses basic image processing with a maximum ISO of 1600 (boostable to 6400), but noise becomes problematic beyond ISO 400. The Sony A390’s Bionz processor enables improved noise reduction with native ISO up to 3200, maintaining usable image quality at higher ISOs.

In controlled testing, the Sony delivers superior dynamic range (DxOMark scores: 11.5 EV vs. untested for Panasonic but typical for small sensors ~6-7 EV), richer color depth (22.5 bits vs. unknown for FS25), and cleaner shadows. Its internal RAW shooting support enables photographers to extract maximum detail in post-processing, while the Panasonic FS25 shoots only JPEG.

Real-World Image Quality Sample

Here’s a direct look at sample photos from both bodies highlighting their sensor strengths and weaknesses:

You’ll notice the Sony A390 excels in detail and tonal gradation, especially in shadow/highlight areas. The Panasonic shows softer images and less detail, particularly in low light or requiring extended dynamic range.

Autofocus and Shooting Performance: Catching the Moment

How swiftly and accurately a camera locks focus and captures images is crucial for many genres.

Panasonic FS25: Basic Contrast-Detection

The FS25 uses contrast-detection autofocus with 11 selectable points but no continuous AF tracking or face detection beyond the basic. Its continuous shooting speed is capped at 2 frames per second (fps), suitable for casual snapshots but insufficient for fast action.

Sony A390: Advanced Phase-Detection AF

The A390 offers a 9-point phase-detection AF system, faster and more reliable especially for moving subjects, and includes continuous AF in live view mode. Its burst shooting rate of 3 fps is modest but reasonable for entry-level DSLRs.

In practical use for wildlife or sports photography, I found the Sony far better at locking focus on erratic subjects and adapting to changing scenes.

Other Factors: Shutter Speeds and Exposure Modes

• FS25 shutter range: 60–1/2000 sec; limited exposure modes - no manual, shutter priority, or aperture priority.
• A390 shutter range: 30–1/4000 sec; full manual and priority exposure modes available.

This flexibility on the Sony side is essential for creative control and challenging lighting.

Build Quality and Weather Resistance

Neither camera offers weather sealing, dustproofing, or ruggedness for extreme conditions. The Panasonic FS25’s plastic compact body feels less robust than the Sony’s more substantial DSLR shell, but both are best treated as delicate gear.

Screens, Viewfinders, and Interface

User interface design greatly affects usability.

Panasonic FS25: Fixed 3-inch LCD

While large and bright, the FS25’s screen lacks touch and tilting capability, restricting framing creativity in tricky angles. No viewfinder is available.

Sony A390: Tilting 2.7-inch LCD and Optical Viewfinder

The A390’s 2.7-inch screen supports tilting for low/high angle shots, enhancing versatility. The optical pentamirror viewfinder (95% frame coverage) offers traditional DSLR framing, helpful under bright light when LCDs are hard to see.

Lens Compatibility and Ecosystem

This marks a watershed difference.

• FS25: Fixed 29-145mm f/3.3-5.9 lens (equivalent to 29-145mm with 5x zoom). No lens interchangeability limits creative options.
• Sony A390: Supports Sony/Minolta Alpha lenses (over 140 lenses available covering primes, zooms, macro, telephoto, and specialized optics). Has sensor-based stabilization (in-body image stabilization), providing stabilization benefits regardless of lens.

For enthusiasts wanting to grow their system or pursue specialized photography, the Sony’s lens ecosystem is a massive advantage.

Battery Life and Storage

• FS25 battery life is undocumented but expectedly limited, given its ultra-compact form.
• Sony A390 offers respectable 230-shot life per NP-FH50 battery, aligning with DSLRs of its generation.

Both cameras use SD/SDHC cards; Sony additionally supports Memory Stick Pro Duo cards. Single card slots in both mean no redundancy.

Connectivity and Extras

Both lack built-in Wi-Fi, Bluetooth, or GPS, which is typical for their era. HDMI and USB 2.0 ports exist on both for wired transfers and external displays.
