A Close Look at the Casio EX-10 vs Samsung ST100: Compact Camera Showdown

In the realm of compact digital cameras, small form factors often come with compromises, but also unique advantages. Today, I’m diving into a detailed, head-to-head comparison between two intriguing ultra- and small-sensor compacts from the early 2010s: the Casio EX-10, launched in late 2013, and Samsung’s ST100 from 2010.

Both cameras offer fixed lenses with notable zoom ranges but come from very different design philosophies and technical lineages. This analysis blends sensor and optics technology, physical ergonomics, shooting performance across disciplines, and value - all grounded in my experience testing hundreds of similar cameras in real-world shooting scenarios. Whether you’re chasing sharp portraits, detailed landscapes, or travel versatility, I’ll help you understand which of these models fits your style and needs best.

Let’s start by sizing up their physical presence and handling.

Compact Bodies, Contrasting Ergonomics

The Casio EX-10 and Samsung ST100 sit in the general category of compact cameras, but their physical dimensions and handling offer quite different experiences.

The Casio EX-10’s measured dimensions (120×68×49 mm) make it a relatively chunky compact, weighing in at 384 grams with battery and card. This heft translates into a more substantial grip and a body that feels solid in hand - a definite advantage for users prioritizing stability, especially when shooting telephoto or in lower light.

In comparison, the Samsung ST100 scales down to a petite, pocketable format at 100×60×20 mm and a featherweight 155 grams. This pocket-friendly ultracompact is ideal for discreet street shooting or travel scenarios where minimal weight matters. The thinner profile naturally reduces grip comfort and can challenge steady handling at the telephoto end but begs less attention in casual carry.

Ergonomically, the EX-10 offers a more traditional posture, with a deeper body providing physical cues for finger placement. Meanwhile, the ST100 makes up for slimness with a responsive touchscreen, though button real estate is necessarily limited.

Looking at the top control layouts, the EX-10 impresses with dedicated dials and buttons for shutter speed, aperture priority, and exposure adjustments; this invites more manual creativity. In contrast, the ST100’s control scheme is streamlined, prioritizing simplicity over granular control - an interface aimed squarely at casual users or those comfortable with auto modes.

For photographers who value tactile feedback and fast access to key settings, the Casio’s design offers a leg up. For those who favor a “point and shoot” experience without the distraction of dials, Samsung’s approach fits snugly.

Sensors and Image Quality: Size and Technology Matter

Behind every camera’s final image quality lies its sensor, arguably the most critical component for photographers. Here, the EX-10 and ST100 favor different sensor sizes and technologies - influencing dynamic range, noise levels, and color accuracy.

The Casio EX-10 uses a 1/1.7" CMOS sensor measuring 7.44×5.58 mm (about 41.5 mm²) and outputs 12 megapixels (4000×3000). CMOS sensors - especially by 2013 standards - tend to outperform CCD in noise handling, speed, and dynamic range. Silvering this, the EX-10 supports RAW image capture, which is invaluable for photographers wanting maximum post-processing latitude.

The Samsung ST100 houses a smaller 1/2.3" CCD sensor at 6.17×4.55 mm (28.1 mm²) with a higher 14 MP resolution (4320×3240). Although it boasts slightly more pixels, smaller sensors packing more pixels often suffer increased noise and a narrower dynamic range. Also, the ST100 lacks RAW support, restricting editing capabilities to JPEG files straight from the camera.

From a practical perspective, the Casio’s sensor size advantage leads to better low-light performance and cleaner images at high ISO settings (up to 12800 native ISO). The Samsung maxes out at ISO 3200 and doesn’t perform as well when noise is factored in.

In landscape and portrait shooting, this makes a tangible difference. The EX-10’s sensor exhibits deeper color depth and improved shadow detail, producing images with richer tonal gradations - critical when capturing delicate skin tones or subtle skies.

Viewing Experience and Touchscreen Interface

Both cameras forgo electronic viewfinders, which is typical in the compact category, instead relying on LCD screens for composition and review.

The Casio EX-10 sports a large 3.5-inch “Super Clear LCD” panel with 922k-dot resolution and a fully articulating tilt mechanism capable of 180 degrees upward tilt. This articulation opens a wealth of creative framing opportunities - think low-angle macros or high-angle street shots - plus easier selfies or vlogging setups, except that the EX-10 lacks a selfie-mode or forward-facing screen.

By contrast, the Samsung ST100 also offers a 3.5-inch screen, slightly higher resolution at 1152k dots, but the panel is fixed. There’s no tilting or articulation, which can constrain creative angles or quick reframing in dynamic scenes.

Both support touch input, facilitating easier focus point selection and menu navigation compared to button-only older designs. However, the EX-10’s touchscreen integrates tightly with its autofocus system, allowing touch AF plus manual override - more on that in a moment.

The EX-10’s LCD brightness and color fidelity tend to be more reliable in bright outdoor conditions, a subtle but important advantage for travel and landscape shooters who often wrestle with glare.

Autofocus Systems and Manual Control: Precision vs Simplicity

A camera’s autofocus (AF) prowess often determines usability across fast-paced genres like wildlife or sports and macro or portrait precision.

The Casio EX-10 employs a contrast-detection AF system with multiple selectable focus modes: single AF, continuous AF, tracking AF, and face detection. It supports touch AF on the screen, enabling precise point selection, aided by eye detection. The continuous AF tracking and face detection help maintain sharpness during moving subjects or candid moments.

Manual focus capability also adds significant creative flexibility, including fine-tuning focus for macro or low-light situations. This is a standout for photographers who want tighter control.

Samsung’s ST100 focuses with a simpler contrast-detection system, limited to single AF with center-weighted focus and some multi-area modes. It lacks continuous AF and any tracking capabilities. There is no manual focus option. While this simplicity may suit casual shooters, it is frustrating for precise compositions or fast subjects.

Real-world testing on wildlife revealed the Casio had smoother, quicker acquisition of moving birds in flight, while the Samsung struggled to keep pace - a predictable gap given hardware and software differences.

Lens Optics and Zoom Performance

Both cameras feature fixed zoom lenses, but their designs prioritize different ends of the spectrum.

The Casio EX-10 sports a 28-112 mm equivalent zoom (4x) with a bright maximum aperture of f/1.8 at wide and f/2.5 at telephoto. This bright lens allows for superior low-light capture, smooth subject-background separation (bokeh), and faster shutter speeds to freeze motion.

By contrast, the Samsung ST100 offers a longer reach from 35-175 mm equivalent (5x zoom), but with a slower aperture range starting at f/3.6 wide, closing to f/4.8 telephoto. The slower lens limits ability to shoot in dim lighting without boosting ISO or slowing shutter speed, which affects image quality and sharpness.

The wider aperture of the Casio is especially noticeable in portrait work, where creamy background blur and sharp subject isolation are prized. The Samsung’s narrower aperture reduces bokeh potential and requires more ambient light, making portraits and indoor shooting more challenging.

Close focusing distances also differ: the EX-10 can focus to 1 cm, granting exceptional macro reach, while the ST100 bottoms out at 5 cm. This advantage gives Casio an edge for detailed close-ups of flowers, insects, or textures.

Burst Speed and Shutter Range: Capturing Motion

Examining continuous shooting capabilities and shutter speed range reveals further performance contrasts important for action or wildlife photographers.

The Casio EX-10 offers a fast 10 frames per second burst mode, suitable for capturing fleeting moments, along with a shutter speed range from 1/250s to 1/4000s, covering most daylight shooting scenarios.

Samsung’s ST100 is limited to a maximum shutter speed of 1/1000s, insufficient for freezing very fast motion under bright conditions, and continuous shooting details are not specified or not available.

Slower minimum shutter speeds on the EX-10 combined with exposure bracketing and timelapse modes allow more creative control for nightscapes or HDR compositions.

Video Capabilities: Full HD vs HD

Video recording may not be the foremost priority for compact camera buyers, but it’s a significant consideration for hybrid shooters.

The Casio EX-10 captures Full HD 1080p video at 30fps or 720p HD at 30fps, encoded in MPEG-4 / H.264 format. Notably, EX-10 includes sensor-shift image stabilization during video, steadying handheld shots and reducing shake.

Samsung’s ST100 maxes out at 720p HD at 30fps, using Motion JPEG codec - an older format less efficient in compression and storage. It also provides additional lower-resolution options but lacks stabilization during video.

Neither camera features microphone or headphone ports, limiting audio control. However, the Casio’s stabilization and higher resolution offer more usable video quality for casual filmmaking.

Battery Life, Storage, and Connectivity

For many photographers, the stamina of a camera and its ease of connectivity shape usage patterns significantly.

The Casio EX-10 uses a rechargeable Li-ion battery (model Li-130A) rated for approximately 455 shots per charge, a respectable figure for the category. It stores images on SD/SDHC/SDXC cards.

Samsung ST100’s specifications are silent on battery life details but uses built-in or proprietary batteries and supports microSD/MicroSDHC memory cards as well as built-in storage, ideal for quick transfers or backups.

In connectivity, the EX-10 includes built-in wireless capabilities (though no Bluetooth or NFC), allowing image transfer or remote control, a convenient feature missing from the ST100, which offers no wireless connectivity.

Both cameras have HDMI and USB 2.0 ports, standard fare for physical transfers and external display connection.

Durability and Environmental Sealing

Neither the Casio EX-10 nor Samsung ST100 feature weather sealing, dustproofing, waterproofing, or shock/freeze resistance - a common trend among compacts aiming for affordability. Neither is ruggedized for professional outdoor abuse, so careful handling remains critical in challenging environments.

For landscape or travel photographers expecting inclement weather, additional protective measures such as rain covers or a weather-sealed bag are advisable regardless of camera choice here.
