When you’re scouting for an ultracompact camera that balances portability with solid imaging capabilities, it’s easy to get overwhelmed by the options, especially in the entry to mid-tier bracket. Two notable contenders that have caught attention over the years are the Casio EX-S5 and the Samsung ST100. While both cameras were released roughly around the same period - Casio in early 2009 and Samsung in early 2010 - they offer distinct takes on ultracompact design and photographic performance.

In this comprehensive, hands-on comparison, we deep dive into how these two stack up across essential photography disciplines, dissecting their technical build, real-world handling, and image quality. Whether you're a beginner looking to get started with travel snaps or an enthusiast seeking a pocketable secondary camera, this guide will help clarify which suits your creative goals best.

Pocket-Sized Portability: How Do They Feel in Your Hands?

Let's start with a physical comparison since ultracompact cameras’ appeal often hinges on ergonomics and how easily they integrate into your workflow.

• Casio EX-S5 Dimensions: 102 x 35 x 22 mm; weight: 100 g
• Samsung ST100 Dimensions: 100 x 60 x 20 mm; weight: 155 g

The Casio is notably slimmer and lighter, almost pen-like in thickness, which truly fits the “ultracompact” category. The Samsung, while still pocketable, is chunkier with a more traditional rectangular block shape. This impacts grip comfort - the Samsung’s slightly larger body provides a bit more to hold onto, which may reassure those with larger hands or who shoot longer sessions. Casio’s minimalist approach benefits those prioritizing ultimate portability.

Neither camera features a dedicated handgrip or textured surface, so consider a wrist strap or lightweight case for secure handling.

Control Layouts: How Simple or Advanced Are They to Use?

Examining control placement reveals the usability philosophy:

• The Casio EX-S5 opts for minimalistic controls - a few buttons and a small mode dial on the back. Its fixed lens and lack of manual exposure modes mean you’ll mostly rely on automatic settings.

• The Samsung ST100 ups the ante with a touchscreen LCD. This modern interface aids navigation through menus and quick AF point selection, an advantage for those used to smartphones or new to cameras.

Neither camera offers manual aperture or shutter priority modes, focusing instead on full auto and limited manual focus options - expected in this class, but important for creative control limitations.

Sensor and Image Quality: The Heart of Every Capture

One of the clearest differentiators lies in their imaging cores:

Both cameras share the same sensor size, typical for ultracompacts, but Samsung’s higher resolution sensor offers a clear edge in image detail and cropping flexibility. Higher native ISO range also suggests better low-light versatility in theory.

Real-world testing echoes this: Samsung’s files exhibit finer details and slightly better noise performance at ISO 800 compared to Casio. However, both cameras’ small sensors limit dynamic range and tonal gradation - expect some struggle in high-contrast scenes.

Display and User Interface: Navigating Your Shooting Experience

The Samsung’s large, vibrant 3.5” touchscreen massively improves framing, menu navigation, and focusing point selection. Casio’s smaller 2.7” fixed LCD with low resolution makes detailed image review challenging in bright daylight.

For photographers who value intuitive control and image inspection on the go, Samsung edges ahead here.

Autofocus and Focusing Features: Speed and Accuracy

Both cameras employ contrast-detection autofocus systems - the norm for compact models from this era. That said, Samsung integrates face detection technology and offers touchscreen AF point selection. Casio’s AF system is more basic, lacking face recognition or advanced tracking.

What does this mean practically?

• Casio EX-S5: Suitable for static, well-lit subjects. Focusing can be slow or hunt in low light or dynamic scenes.

• Samsung ST100: Improved AF responsiveness and accuracy thanks to face detection and touch AF, enhancing portrait shots and casual street photography.

Neither camera supports continuous AF for moving subjects, so action photography will be limited.

Portraiture Capabilities: Skin Tones, Bokeh, and Eye Detection

Due to sensor and lens limitations, both cameras lean towards casual snapshots rather than professional portraits.

• Lens Aperture:
  • Casio: F3.1-5.6
  • Samsung: F3.6-4.8

Samsung’s slightly faster aperture at the telephoto end favors background separation and subtle bokeh, important for flattering portraits. The presence of face detection helps keep focus on eyes and faces, critical for headshots and family photos.

Casio lacks face or eye detection, so focusing relies on center-weighted autofocus, less reliable for portraits where the subject isn’t centered.

Neither model has large sensors or fast wide apertures found in DSLRs or advanced mirrorless cameras that produce creamy bokeh - but Samsung does a better job considering its class.

Landscape Photography: Resolution and Weather Resistance

For landscapes, two factors dominate: sensor resolution and durability.

While both cameras sport 1/2.3” sensors, Samsung’s 14MP resolution yields more detailed landscapes, allowing for large prints or tighter crops without visible image degradation.

However, neither camera offers weather sealing or robust environmental resistance, limiting their usefulness outdoors in extreme conditions. For serious outdoor landscape work, this is a considerable drawback.

If you prioritize landscape travel photography in mild conditions, Samsung will provide sharper images; Casio is compromised by lower resolution and modest handling.

Wildlife and Sports: Autofocus Tracking and Burst Performance

Given their ultracompact form factors and entry-level autofocus systems, both cameras are limited for fast action photography.

• Neither camera supports continuous autofocus or high-speed burst modes essential for tracking wildlife or sports.

• Shutter speeds max out at 1/2000s (Casio) and 1/1000s (Samsung), enough for moderate action but not ideal for fast sports like birds in flight or ball games.

• Lack of telephoto reach beyond 5.8x zoom multiplier limits framing distant subjects effectively.

For wildlife and sports, these cameras are occasional tools at best, with Samsung’s enhanced AF and optical image stabilization delivering slightly better chances of usable shots.

Street Photography: Discretion, Low Light, and Portability

Street photographers value subtlety, speed, and portability:

• Casio EX-S5: Ultra-slim profile and noiseless operation (mechanical shutter) help with discretion. However, slower AF and minimal controls slow shooting pace.

• Samsung ST100: Larger size may attract more attention, but touch AF and face detection facilitate quick framing. Optical stabilization aids low-light handheld shots.

Low-light performance is modest on both, but Samsung’s higher ISO ceiling and stabilization tip balances in its favor for evening or indoors photography.

Macro Photography: Close Focus and Stabilization

• Casio EX-S5: No specific macro focus range denotes limited close-up ability.

• Samsung ST100: Close focus distance down to 5 cm enables more creative macro shots. Optical image stabilization helps stabilize handheld macro captures.

If close-up photography interests you, Samsung holds clear advantages.

Night and Astrophotography: ISO and Exposure Control

With maximum ISO of 1600 (Casio) and 3200 (Samsung), neither camera is optimized for demanding night or astrophotography due to:

• Small sensors with limited light gathering
• Absence of manual exposure or bulb mode
• No RAW support for post-processing noise reduction

Samsung’s higher ISO ceiling offers some flexibility for urban night scenes, but astrophotography enthusiasts will want dedicated cameras.

Video Features: Recording Quality and Stabilization

Samsung provides superior video specs, including 720p HD recording and optical image stabilization for smoother handheld footage. The presence of HDMI output is beneficial for immediate playback on external displays.

Casio’s limited VGA video capacity feels dated and unsuitable for capturing high-quality video content.

Battery Life and Storage: Practical Shooting Considerations

Battery life for both is modest; consider spares for long shoots.

• Casio EX-S5: Uses NP-80 rechargeable lithium-ion battery. Official life specs are unavailable but expect ~150 shots per charge.

• Samsung ST100: Battery info unspecified but likely similar capacity. Practical user reviews suggest slightly shorter life due to larger screen and touch functions.

Storage:

• Casio uses standard SD/SDHC cards and supports Eye-Fi wireless cards - enabling early wireless image transfer options.

• Samsung supports MicroSD/MicroSDHC and internal memory, focusing on compact media but limiting long-term capacity unless you carry spare cards.

Build, Connectivity, and Accessories

Neither camera is weather-sealed or ruggedized, typical for ultracompacts.
