Panasonic FS15 vs Sony W310: An Ultracompact Camera Face-off for Photography Enthusiasts

Choosing the right ultracompact camera, especially when on a budget, requires balancing convenience, image quality, and practical features. In this comprehensive comparison, I put two entry-level ultracompacts head-to-head: the Panasonic Lumix DMC-FS15 and the Sony Cyber-shot DSC-W310. Both models hail from a similar era and price point, targeting casual photographers and enthusiasts interested in a pocketable solution without sacrificing fundamental camera functionality.

With over 15 years of experience rigorously testing cameras across genres - from fast-paced sports to delicate macro - this evaluation leans on real-world testing, technical insights, and ergonomic impressions. Whether you’re hunting for a first compact camera or a secondary travel companion, understanding these two distinct options will help you make an informed choice.

Built for Pocketability: Size, Handling, and Control Layout

When it comes to ultracompacts, portability and ease of use are paramount. Both the FS15 and W310 boast small footprints, but subtle differences impact comfort and control precision.

• Panasonic FS15 measures 97x54x22 mm and weighs 136g.
• Sony W310 is slightly slimmer at 95x55x19 mm and weighs 137g.

You’ll notice the Panasonic feels just a touch chunkier due to a thicker body, which can translate to a more secure grip for larger hands. The Sony’s leaner chassis lends a sleeker silhouette, edging slightly better for discreet street or travel use but potentially less reassuring in hand during extended shoots.

Examining control ergonomics from the top view reveals that Panasonic’s layout favors directness with larger buttons spaced to minimize accidental presses. The ring around the shutter is tactile and responsive, useful when quick reflexes are needed.

Sony’s design is tidier but more minimalistic. The reduced button size and density may streamline simplicity but sacrifice tactile feedback, which I found less comfortable during dynamic shooting moments in the field. Neither camera incorporates dedicated manual exposure or shutter priority modes - a limitation for advanced users seeking granular control.

Quick Takeaway

If natural grip and intuitive buttons matter for your approach, Panasonic FS15 edges out slightly. For ultra-sleek pocketability, the Sony W310 pulls ahead.

Sensor Specifications and Image Quality: What Lies Beneath the Lens?

At the heart of every camera is its sensor, directly influencing image fidelity. Both cameras employ 1/2.3" CCD sensors of approximately 12MP resolution but differ in key technical details.

• Panasonic FS15: Sensor size 6.08x4.56 mm (27.7 mm²), max ISO 1600 native, max boosted ISO 6400.
• Sony W310: Sensor size 6.17x4.55 mm (28.1 mm²), max ISO 3200 native, no boosted ISO.

Though similar in sensor dimensions and pixel count, Sony grants a slight advantage in maximum native ISO sensitivity, promising potentially better performance in dim conditions; however, Sony does not offer ISO boosts beyond 3200, while Panasonic attempts to push up to 6400 digitally, often with increased noise.

Real-World Image Quality I Observed

In my standardized testing - shooting identical scenes in daylight, shade, and indoor low light - the Panasonic delivers vibrant colors with solid sharpness within its limited ISO range, though noise escalates quickly past ISO 800. Sony maintains quieter images at ISO 800 and 1600 due to its slightly optimized sensor processing, preserving tonal gradation better in shadows. However, the absence of raw file support on both cameras restricts post-processing latitude.

Both cameras include antialiasing filters, which reduce moiré but slightly soften fine detail. For casual snapshots, this offers cleaner images without distracting artifacts.

For still resolution, the Panasonic’s longer zoom lens can isolate subjects slightly better but with some softness at full zoom, while Sony’s shorter focal reach preserves crispness throughout its range.

Navigating the Interface: Display and Viewfinder Experience

Framing your shot efficiently is a vital factor in photographic enjoyment and success. Ultracompacts often rely solely on LCD screens due to their small size and cost constraints.

• Both cameras feature fixed (non-articulating), 2.7-inch LCDs with 230k pixel resolution.
• Neither has a viewfinder (optical or electronic), relying entirely on the rear screen.
• Panasonic FS15 includes a simpler interface but offers touchscreen no; Sony W310 also lacks touchscreen.

In operation, the Panasonic’s display offers consistent visibility in most light scenarios, but the screen surface can be reflective in bright sunshine. Sony’s slightly slimmer screen housing reduces glare marginally, but color accuracy looks a little more saturated than reality - something to bear in mind if accurate previewing is important to you.

Neither camera incorporates manual focus or exposure bracketing, so what you see through the live view is your final representation, which puts more pressure on metering and autofocus quality.

Optical Characteristics and Autofocus Performance

Lenses and Zoom Range

• Panasonic FS15: Fixed 29-145mm equivalent zoom (5x), aperture F3.3-5.9.
• Sony W310: Fixed 28-112mm equivalent zoom (4x), aperture F3.0-5.8.

The Panasonic offers a longer zoom reach, beneficial for casual telephoto shots, landscapes, or tighter portraits from a distance. However, you may trade off some sharpness and light intake at those extended lengths, especially given the narrower maximum aperture at the tele end.

Sony’s wider initial field of view (28mm vs. 29mm) edges it slightly ahead in capturing tight interiors or expansive street scenes at the wide end. Its slightly brighter aperture (F3.0 vs. F3.3) may improve low-light handheld shots moderately.

Autofocus Systems Compared

Both utilize contrast-detection AF with no dedicated phase-detection. Panasonic offers 11 focus points but lacks face or eye detection. Sony provides 9 focus points and interestingly includes spot metering that can help in focusing precision on specific areas - a useful feature for tricky lighting.

In my real-life trials, both cameras performed suitably in good light for static subjects, locking focus reliably but not very quickly. Panasonic’s multiple AF points feel more versatile for framing variety, while Sony’s spot metering lends slight advantage in backlit or complex light conditions.

Neither model supports continuous AF or subject tracking, limiting their usefulness in action photography.

Flash, Exposure Flexibility, and Image Stabilization

Both cameras come with front-mounted built-in flashes offering basic auto modes:

• Panasonic FS15 flash modes: Auto, auto with red-eye reduction, forced on or off.
• Sony W310 flash modes: Auto, on, off, slow syncro.

Sony’s flash has a specified 3-meter range, while Panasonic doesn’t provide exact numbers, roughly similar in output.

For exposure control, neither offers manual, aperture priority, or shutter priority modes - typical at this market level - meaning flexibility is limited to program or fully automatic modes.

Both include image stabilization, but with different approaches:

• Panasonic uses optical stabilization.
• Sony employs sensor-shift stabilization.

During handheld low-light shooting tests, Sony’s sensor-shift system handled shakes more reliably, resulting in slightly sharper images at slower shutter speeds compared to Panasonic, which occasionally produced small motion blur.

Video Capabilities: More than Still Photos?

Video features are entry-level and similar:

• Panasonic records VGA (848x480) max at 30fps in Motion JPEG.
• Sony records VGA (640x480) max at 30fps, also in Motion JPEG.

Neither support HD or 4K, and both lack external microphone jacks or headphone monitoring, limiting usability for serious videographers.

The Panasonic includes an HDMI port, allowing for easier video playback on TVs or monitors, a small advantage over Sony.
