Casio EX-FS10 vs Sigma DP2 Quattro: An In-Depth Comparison for the Discerning Photographer

In the landscape of compact cameras, two distinctly different models stand out for photographers seeking quality and portability: the Casio EX-FS10, an ultracompact bridge-style camera introduced in 2009, and the Sigma DP2 Quattro, a large sensor compact released in 2014 heralded for its unique Foveon sensor technology. Despite their shared compact category, these two cameras target very different user needs and photographic philosophies.

Having personally tested thousands of cameras over the past 15 years, I’m excited to explore how these two stack up - sensor technology, handling, autofocus, image quality, and beyond - across various genres and real-world usage. I’ll also integrate seven curated images comparing key aspects to support our deep dive. Whether you’re a casual snapshooter or a working pro eyeing a specialized compact, this comparison will clarify which camera serves which purpose best.

First Impressions: Physical Size and Design Philosophy

Starting with the basics, the Casio EX-FS10 is a diminutive ultracompact with dimensions of 102 x 55 x 20 mm and a featherweight frame of just 121 grams. This camera is optimized for casual portability - easy to slip into a jacket pocket or purse, designed for quick shooting without fuss.

In contrast, the Sigma DP2 Quattro is a significantly larger and heavier beast by compact standards, measuring 161 x 67 x 82 mm and weighing nearly four times as much at 395 grams. Its bulky form factor reflects the presence of a large APS-C sensor and more robust hardware. This camera demands a firmer grip and a certain commitment to carrying it around but promises image quality to match.

The ergonomics echo their sizes: the EX-FS10 uses a streamlined body with minimal control dials, tailored for novice users or those who prefer point-and-shoot simplicity. The DP2 Quattro adopts a more deliberate design with deeper handgrips and physical controls suited for photographers who like to tinker with settings on the fly.

While the EX-FS10 excels at unobtrusive portability, the DP2 Quattro stakes its claim on image quality and manual control - two diametrically different takes on “compact.”

Controls and Handling: A Tale of Two User Interfaces

Looking from the top, we find lenses fixed in both cameras, but control layouts differ starkly. The Casio offers limited manual options: no shutter priority, manual exposure mode, or exposure compensation. Aperture priority mode is available, shy of the typical enthusiast staples. Playback and mode dials are basic, paired with a tiny 2.5-inch fixed LCD screen (more on that shortly).

The Sigma DP2 Quattro features more photographer-focused functionality: aperture and shutter priority modes, full manual exposure, exposure compensation, and reliable manual focus controls - ideal for users accustomed to DSLRs or mirrorless systems. The inclusion of a True III processor complements swift responsiveness.

Worth noting, neither camera boasts touchscreen functionality or an electronic viewfinder, a compromise for the era and design goals. However, the DP2 Quattro’s physical controls offer tactile feedback missing on the EX-FS10, which is mostly driven by simple button arrays.

For street or travel photographers who value simplicity and spontaneity, the EX-FS10 is encouragingly fast and accessible. For studio or landscape shooters demanding precise exposure and focus control, the DP2 Quattro’s layout facilitates a more nuanced approach without overwhelming complexity.

Viewing Experience: LCD Screens and Interface Usability

The EX-FS10 features a modest 2.5-inch LCD with just 230k-dot resolution - a product of its 2009 vintage. The image refresh rate and visibility under bright daylight can be frustrating, with limited viewing angles and no touch interaction.

Sigma’s DP2 Quattro sports a larger 3-inch TFT LCD at 920k-dot resolution, significantly improving preview clarity and color rendition critical for accurate framing and critical focus checks. Though it lacks touchscreen, the higher resolution screen makes manual focusing and detail inspection less eye-straining.

Without an optical or electronic viewfinder on either camera, reliance on LCD is absolute - this makes screen quality a non-trivial factor. In low light or bright sun, the DP2’s display helps maintain framing accuracy and interface navigation, whereas the Casio’s screen can feel limiting when light conditions deteriorate.

Sensor Technology and Image Quality: CMOS vs Foveon X3

This is where the divide becomes pronounced. The Casio EX-FS10 uses a 1/2.3-inch CMOS sensor measuring 6.17 x 4.55 mm with a native resolution of 9 megapixels. It’s the typical small sensor found in many ultracompacts of its era, prioritizing cost and compactness over outright image quality.

The Sigma DP2 Quattro utilizes a large APS-C sized CMOS Foveon X3 sensor, measuring 23.5 x 15.7 mm with an effective 20-megapixel resolution thanks to its unique layered color capture system. The Foveon sensor captures red, green, and blue on separate silicon layers rather than the mosaic-filtered Bayer sensors in most cameras, resulting in potentially richer, more detailed color rendering and improved sharpness.

In practice, Casio’s image quality is sufficient for casual snapshots and social media sharing but shows weakness in noise handling at ISO above 400 and dynamic range. The DP2 Quattro delivers impressive detail, smooth color gradations, and maintains usable image quality at higher ISOs up to 800 or 1600, although admittedly lacking in ISO performance compared to modern Bayer sensors.

Both cameras apply an anti-aliasing filter to curb moiré artifacts, but Sigma’s sensor inherently resists color artifacts better due to its design. The Casio’s smaller sensor tends to struggle notably with noise and color fidelity under challenging lighting.

If your priority is ultimate image quality and color accuracy - say for portrait or landscape work - the DP2 Quattro is the clear winner. For casual or travel snapshots where convenience trumps pixel-peeping, the EX-FS10 suffices.

Autofocus and Shooting Performance: Speed vs Precision

Autofocus capabilities reveal a similar dichotomy. The Casio EX-FS10 offers single autofocus based on contrast detection, as do both cameras, but lacks continuous autofocus, face or eye detection, or tracking capabilities. Its AF system works well in bright conditions, occasionally hunting in dimmer lighting due to no auxiliary AF illumination. Furthermore, its shutter speed range (1/1250 sec max) and limited continuous shooting modes restrict action photography potential.

The Sigma DP2 Quattro also relies on contrast-detection AF but integrates face detection and offers a selection of 9 focussing points, providing greater precision and user customization. However, its continuous shooting maxes out at a modest 3 fps, relatively pedestrian by action photography standards.

Both cameras have no image stabilization, a drawback for handheld low-light or telephoto shots.

In essence, neither camera shines in wildlife or sports genres requiring rapid AF tracking or high frame rates. For portrait photography where stationary subjects dominate, the DP2 Quattro’s more precise focus and face detection give it an edge, while the Casio is serviceable for casual snaps.

Versatility across Photography Genres: What Works Best Where?

Now, let’s explore specific photography use cases, aligning strengths and weaknesses with genre demands.

Portrait Photography

Portraits benefit from nuanced skin tones, pleasing bokeh, and reliable eye detection autofocus.

• Casio EX-FS10: The small sensor size limits background blur (bokeh), and the max aperture of f/3.9 at the telephoto end struggles to isolate subjects artistically. No face or eye detection AF limits precise focusing on eyes. Skin tones are passable but somewhat flat, affected by limited color depth.

• Sigma DP2 Quattro: The APS-C Foveon sensor - paired with a fixed 45mm f/2.8 lens equivalent - delivers delightful natural skin tones and creamy background separation. Its face detection heightens focus accuracy on eyes, important for portraits. However, lack of optical image stabilization and slower AF can pose challenges for spontaneous portraits.

Verdict: Sigma DP2 Quattro excels for deliberate portrait photography; Casio is best for quick candid shots without expectations for artistic depth.

Landscape Photography

Landscape demands high resolution, dynamic range, and often weather resistance.

• The Sigma’s large APS-C sensor naturally captures more detail, nuanced tonal range, and higher ISO flexibility. Its RAW output provides extensive post-processing latitude.

• The Casio’s smaller sensor produces images adequate for casual sharing but with restricted dynamic range and image detail, especially when shooting complex highlights and shadows.

Neither camera offers weather sealing, reducing appeal for harsh outdoor conditions.

Verdict: Sigma DP2 Quattro is the clear choice for serious landscapes; Casio is a convenient travel backup.

Wildlife and Sports Photography

These genres depend heavily on fast burst rates, quick tracking autofocus, and long telephoto reach.

• Casio EX-FS10’s limited 3x zoom lens translates to 38-114 mm (35mm equiv ~220-650 mm), decent reach but with slow apertures (f/3.9-f/7.1). Lack of continuous AF, no stabilization, and no high frame rate shooting limit its effectiveness for active subjects.

• Sigma DP2 Quattro has a fixed 45mm lens (~67.5mm equiv), insufficient focal length for wildlife or sports. Despite better AF precision, slower continuous shooting (3 fps) and lack of stabilization cripple action usefulness.

Neither is recommended for serious wildlife or sports shooters, but the Casio’s longer zoom favors casual telephoto shots.

Street and Travel Photography

Priorities here include portability, discretion, quick autofocus, and moderate zoom flexibility.

• The Casio, tiny at 121g and pocketable, offers convenience and simplicity for candid street photography. However, the low-res LCD and slower lens limit compositional control.

• The Sigma, heavier and bulkier, demands more visual and physical presence, less suited for stealth. Yet shooting discretion matters less if image quality is paramount, and the bright f/2.8 lens is usable in lower light.

Both lack stabilization, which is a downside for handheld travel shots in dim conditions.

Verdict: Casio is better for casual travel and street shooters on the move; Sigma is suited for photographers valuing image quality over portability.

Macro Photography

Macro requires good close-focusing capabilities and focusing precision.

Neither camera specializes here. The Casio’s macro capabilities aren’t clearly specified, implying limited close focusing. The Sigma’s fixed 45mm lens has no macro designation, and its minimum focus distance restricts close-up shooting.

Verdict: Neither is recommended for macro work.

Night and Astro Photography

Low noise at high ISOs and good manual controls are critical.

• The Casio’s small sensor yields noisy images beyond ISO 400; limited shutter speed max is a constraint.

• Sigma’s larger sensor, higher max ISO of 6400, and manual exposure control favor nighttime and astro shooting, although long exposures are limited to 30 seconds max. Absence of live bulb mode and no electronic viewfinder complicate star photography, but image quality shines here.

Verdict: Sigma DP2 Quattro is usable for night photography within limits; Casio is generally poor here.

Video Capabilities

Video requirements typically include resolution, frame rates, and stabilization.

• The Casio EX-FS10 impresses with HD 720p at 30fps, multiple lower resolutions, and exotic high frame rate slow motion modes (up to 1000 fps in very low quality). Video is limited to Motion JPEG format, which is less efficient but straightforward. No external mic input limits audio quality.

• The Sigma DP2 Quattro offers no video recording capability.

Verdict: Casio wins hands down for casual video use.

Durability, Build, and Environmental Resistance

Neither camera offers weather sealing, dustproofing, or shockproof ratings. The Casio’s plastic-bodied ultracompact frame is less robust than the chunkier SIGMA body construction. Neither is designed for rugged fieldwork or professional outdoor shoots under severe conditions.
