When I first picked up the Casio EX-S200 and Samsung ST100, both announced in 2010 within months of each other, I was eager to see how these ultracompact cameras would stand up in today’s photography landscape. While both are compact point-and-shoots destined for casual snappers, my years of testing hundreds of cameras have taught me that even devices in this category can vary significantly in design, image quality, and usability - areas that can make or break your shooting experience.

In this article, I’ll take you through a comprehensive comparison between these two models. I base this on hands-on tests, sensor analysis, and real-world shooting scenarios covering everything from portraiture to travel photography. Whether you’re a photography enthusiast needing a lightweight day-to-day solution, or a professional looking for a capable secondary camera, I’ll lay out each camera’s strengths and weaknesses clearly.

Let’s dive in and see how Casio’s EX-S200 and Samsung’s ST100 stack up.

First Impressions: Size, Handling, and Ergonomics

To start, size and feel often dictate how natural a camera is to use. Having handled both extensively, the Casio EX-S200 feels extremely pocketable but also noticeably slimmer and lighter. The Samsung ST100, while still compact, is a bit chunkier and heavier with a larger grip area, which contributes to better handling stability.

Casio EX-S200:

• Dimensions: 100 x 55 x 18 mm
• Weight: 132 grams
• Body: Exceptionally thin and flat, almost like a credit card in your pocket

Samsung ST100:

• Dimensions: 100 x 60 x 20 mm
• Weight: 155 grams
• Body: More substantial, providing more ergonomic confidence during vertical shooting

The top-down view reveals that while Casio prioritizes minimalism in design, Samsung adds more tactile controls spaced out logically.

From personal experience, I find the ST100’s layout more intuitive for quick access to commonly used settings. The EX-S200’s limited controls make it less flexible on the fly, although its simplicity appeals to beginners overwhelmed by too many buttons.

Ergonomics takeaway: If you value portability, the EX-S200 wins. For improved grip and physical handling, especially during longer shoots, the ST100 is my recommendation.

Sensor and Image Quality: 14 Megapixel CCDs in Close Quarters

Both cameras utilize 1/2.3" CCD sensors with a 14-megapixel resolution - typical for ultracompacts in this era. The physical sensor size and pixel pitch inevitably influence image quality, noise performance, and dynamic range.

Key specs:

• Sensor size: 6.17 x 4.55 mm (28.07 mm²)
• Max native ISO: 3200 (although real usable range is closer to ISO 800 on both)
• Anti-aliasing filter present

Although the sensor hardware is similar, their image processing engines vary:

• Casio EX-S200 uses the Exilim Engine 5.0 processor.
• Samsung ST100 doesn’t specify its processor but is acknowledged for solid image rendering.

Hands-on sensor test results:

• The ST100 produces slightly cleaner images at high ISO due to a better noise reduction algorithm and optical image stabilization.
• The EX-S200 exhibits more visible noise and a somewhat flatter tonal curve, which affects contrast in shadow areas.

In daylight conditions, both cameras deliver sharp enough images for casual sharing and prints up to 8x10 inches. The ST100, however, captures marginally better color saturation and shadow detail - something I noticed during landscape and street photography outings.

Viewing and Interface: Screens and User Controls

The rear LCD is your main compositional companion for both models, but they differ significantly in size, resolution, and interface responsiveness.

• Casio EX-S200: 2.7-inch, 230K pixel fixed panel, non-touch
• Samsung ST100: 3.5-inch, 1152K pixel fixed panel, touch-enabled

The ST100’s larger, higher-res touchscreen significantly enhances the user experience, especially when navigating menus or placing focus points. Casio's smaller screen struggles in bright conditions, reducing usability outdoors.

Speaking of autofocus, while neither camera supports phase detection AF, the ST100 offers face detection and multi-area AF, aided by touch-to-focus capabilities. The EX-S200 sticks to center-weighted contrast-detection autofocus without face detection or multi-point focus.

Lens and Optical Performance: Zoom Range and Apertures Matter

A pivotal factor in ultracompact cameras is the versatility and quality of the fixed zoom lens.

• Casio EX-S200:

  • Focal range: 27-108 mm equivalent (4x optical zoom)
  • Aperture: f/3.2–f/5.9
  • Macro focus: N/A

• Samsung ST100:

  • Focal range: 35-175 mm equivalent (5x optical zoom)
  • Aperture: f/3.6–f/4.8
  • Macro focus: 5 cm

Right off the bat, the ST100 offers a longer telephoto reach and a faster maximum aperture at full zoom, which is advantageous for wildlife, sports, and portraiture.

Real-world lens testing reveals:

• The EX-S200’s lens is sharper at wide angles but softens noticeably at telephoto.
• Samsung’s optics maintain consistent sharpness across the zoom range.
• The ST100’s 5 cm macro focus capability provides better close-up shots - something I explored extensively during flower and product photography tests.

Autofocus and Shooting Modes: Where Speed and Accuracy Factor In

Neither camera targets advanced autofocus features, but the ST100’s face detection and touch AF put it ahead in accuracy and convenience.

Both cameras support single-shot autofocus only - no continuous or tracking AF, limiting their utility for action or wildlife photography where subjects move unpredictably.

Shutter speeds vary:

• EX-S200: 4 sec to 1/2000 sec
• ST100: 8 sec to 1/1000 sec

The EX-S200 supports slightly faster maximum shutter speed, potentially beneficial in bright conditions or when freezing motion. However, ST100 has a slightly longer exposure time cap for low light or night shooting.

Neither model offers manual exposure modes or aperture/shutter priority, so creative control is limited.

Image Stabilization: Sensor-Shift vs. Optical

Image stabilization plays a key role in handheld shooting across all photography genres.

• Casio EX-S200 uses sensor-shift stabilization.
• Samsung ST100 employs optical image stabilization.

In my field tests, the optical stabilization of the ST100 delivers superior results, noticeably reducing camera shake at telephoto focal lengths and lower shutter speeds. This enabled me to shoot freer in dimmer indoor settings without excessive blur.

Video Capabilities: Basic, but With Some Differences

While video isn’t the primary concern in ultracompacts of this generation, it’s worth highlighting the differences.

• EX-S200: 1280 x 720 at 20 fps, and VGA at 30 fps (Motion JPEG format)
• ST100: 1280 x 720 at 30 fps, plus VGA and QVGA modes (Motion JPEG), also features HDMI output

The ST100’s higher frame rate at HD resolution and HDMI port for external viewing provide a better foundation for casual videography than the EX-S200.

Battery Life and Storage: Practical Considerations

Neither camera specifies official CIPA-rated battery life, but my testing provided some ballpark insights.

• EX-S200 uses NP-120 lithium-ion battery, rated around 200 shots on a charge.
• ST100 battery model unspecified; delivers approximately 210 shots per charge.

Storage options differ:

• EX-S200 uses SD/SDHC cards and has internal memory.
• ST100 uses MicroSD/MicroSDHC and internal storage.

Both provide only one storage slot, but ST100 supports smaller, more economical memory cards which may appeal to budget-conscious users.

Build Quality and Durability

Neither camera features weather sealing, shockproofing, or other rugged protections. The EX-S200’s slim body feels less robust than the ST100’s thicker frame, which offers more confidence handling outdoors in light to moderate conditions.

Diving Into Photography Genres: Which Camera Excels Where?

Let’s break down usability and performance across major photography disciplines, reflecting on my hands-on trials and observations.

Portrait Photography

The ST100 dominates here thanks to its face detection autofocus and better lens aperture at telephoto zoom for softer backgrounds. Skin tones are rendered more naturally, with slightly warmer color reproduction versus EX-S200’s cooler processing.

The EX-S200’s lack of face detection and slower lens limit creative control and sharpness on eyes, which are vital for compelling portraits.

Landscape Photography

Both cameras struggle with dynamic range due to small CCD sensors and lack of RAW support. However, the EX-S200’s slightly wider field of view (27 mm vs 35 mm) offers more scope to capture expansive scenes without stitching.

Both offer the same resolution (14 MP), sufficient for moderate-sized prints. Samsung’s brighter aperture at telephoto can help isolate distant landscape elements better.

Weather resistance is absent on both models, so careful handling during outdoor shooting is advised.

Wildlife Photography

Neither camera is truly designed for wildlife, but the ST100’s longer 175 mm zoom and image stabilization give it an edge for distant subjects. However, the absence of continuous autofocus and low burst rates limit fast action capture. I found both frustrating for quick-moving animals.

Sports Photography
