Comparing the Casio EX-H15 and Samsung SL30: A Thorough Evaluation of Two Small-Sensor Compacts

In the compact camera segment, particularly models featuring small sensors, discerning photographers must navigate a landscape where minute differences in features seriously impact real-world usability. The Casio EX-H15, announced in early 2010, and the Samsung SL30 (also known as ES15), released in early 2009, represent two competitive entries aimed at casual to enthusiast users seeking lightweight, pocketable solutions with built-in zoom lenses. This evaluation, based on extensive technical scrutiny and hands-on testing patterns, compares these two models across the core photographic disciplines and everyday scenarios, emphasizing pragmatic usability, operational transparency, and value considerations.

Physical Design and Handling Ergonomics

A fundamental requirement for travel, street, and casual photography is the physical intimacy between camera and user. Executed measurements reveal both the Casio EX-H15 (101x60x28mm, 161g) and Samsung SL30 (94x61x23mm, 140g) reside firmly within compact form factors. The Casio is marginally larger and heavier, which translates into a slightly more substantial grip and perceived solidness in hand. The Samsung’s slimmer profile contributes to superior pocketability, albeit with a tradeoff in button real estate and presumably reduced handling confidence during rapid operation.

Control placement reveals that neither model offers the external dials or dedicated manual exposure controls typical in advanced compacts. Casio’s EX-H15 includes limited dedicated buttons with no illuminated feedback, while Samsung’s SL30 has a simpler control array, potentially impacting operation under varied lighting conditions. Both rely on fixed lens design, forgoing interchangeable lens flexibility but benefitting from compactness.

Sensor Architecture and Image Quality Fundamentals

Both cameras employ a 1/2.3" CCD sensor, a standard for their era and class, but differ in resolution and sensor area minimally. Casio’s 14-megapixel unit (4320x3240 max resolution) slightly exceeds Samsung’s 10-megapixel sensor (3648x2736), which could suggest higher detail potential. However, the effective sensor area is similar, with Casio’s sensor measuring 6.17x4.55 mm against Samsung’s 6.08x4.56 mm, indicating negligible difference in photon collection capability.

The CCD sensor type impacts low-light performance and dynamic range: while CCDs are known for decent color fidelity and low noise at base ISO, they tend to deliver less flexibility at higher sensitivities compared to modern CMOS sensors. Neither camera supports RAW files, which significantly constrains post-processing latitude and professional workflows.

Practically, this means both models are suited to well-lit environments and casual image capture, rather than demanding photographic work requiring extensive tonal adjustment or archival quality files. Casio offers a higher maximum ISO (3200 vs. 1600 on Samsung), but anecdotal evidence from similar CCD cameras of the era suggests image noise rapidly degrades above ISO 400-800, limiting practical use of extended ISO settings.

Lens Optics and Zoom Range: Versatility Versus Speed

Casio’s zoom lens spans 24-240mm equivalent (10x optical zoom) with an aperture range of f/3.2-5.7, while Samsung provides a more modest 38-114mm range (3x zoom) at f/2.8-5.7 aperture.

Longer zoom range on Casio benefits landscape and wildlife photographers who require reach flexibility without carrying multiple optics. However, the narrower maximum aperture at telephoto end (f/5.7) reduces low-light capture capability and depth-of-field control. Samsung’s brighter wide end (f/2.8) potentially aids in low-light and offers better subject isolation, a boon for portrait and street photography. Still, the shorter zoom range limits framing versatility.

Importantly, Casio includes sensor-shift image stabilization, a notable inclusion enhancing telephoto usability and hand-held macro potential, whereas Samsung lacks stabilization altogether, raising the risk of motion blur at the long end or slower shutter speeds.

Display Interface and Viewfinding

Neither model features an electronic viewfinder, relying exclusively on rear LCDs. Casio offers a 3-inch fixed screen with 461k-dot resolution, substantially sharper and larger than Samsung’s 2.5-inch 230k-dot display. This difference impacts framing accuracy, focus verification, and menu navigation clarity.

Casio’s larger, higher-res screen benefits travel and landscape photographers who require precise composition and focus-checking in-the-field. Samsung’s lower resolution screen may hinder reliable focus confirmation, especially under variable lighting or for users with less than optimal vision.

Autofocus Systems and Manual Operation

Neither camera features advanced autofocus capabilities common to newer models. Both use contrast-detection AF confined to single-point or multi-area modes but differ in face detection availability - Samsung includes face detection whereas Casio does not. Additionally, Samsung’s autofocus supports center-weighted focusing, while Casio’s system is more limited.

Both lack continuous AF and tracking modes, limiting sports or wildlife shooting effectiveness where fast-moving subjects predominate. Casio offers manual focus control, an advantage for macro and creative shooters desiring precise focus adjustment. Samsung omits manual focus altogether, potentially frustrating users tackling close-up or artistic manual focusing challenges.

Burst Capture and Shutter Performance

Neither model advertises continuous shooting modes or high burst frame rates. Casio offers shutter speeds ranging from 4 to 1/2000 sec, whereas Samsung’s shutter range extends from 8 to 1/1500 sec. While shutter velocity capabilities appear sufficient for basic motion freezing, absence of rapid frame-rate sequences curtails sports or wildlife photography endeavors.

Longer minimum shutter speeds (4-8 seconds) support night and astro photographers in capturing long exposures, although the lack of bulb or customizable exposure times limits versatility.

Flash Systems and Illumination

Built-in flashes are standard on both, with Casio supporting Auto, On, Off, and Red-Eye Reduction modes. Samsung expands flash modes with Slow Sync, Fill-in, Red-Eye Fix, and similar variations, enabling more nuanced control over ambient-light balance and fill lighting. Flash range is unspecified on Casio but rated at 4.6m for Samsung, indicating moderate effectiveness in small rooms or for short-range fill.

Neither supports external flashes, constraining low-light creativity and professional lighting workflows.

Battery, Storage, and Connectivity

Both cameras utilize proprietary batteries (Casio NP-90; Samsung model unspecified) with no user-friendly battery life details. The weight advantage of the SL30 may extend marginally to battery endurance, but real-world testing is required for confirmation.

Storage support includes SD/SDHC cards on Casio and SD/SDHC/MMC cards on Samsung. Casio offers Eye-Fi wireless card compatibility, an edge for early adopter wireless image transfer without physical connection; Samsung provides no wireless features.

Connectivity on both is limited to USB 2.0, restricting fast data transfer or docking station compatibility for professional workflows.

Video Capabilities

Video performance on each camera is basic. Casio features 1280x720 HD recording at 30fps, a rare inclusion in early-2010-era compacts and advantageous for casual videography.

Samsung’s highest resolution is 800x592 at a lower 20fps frame rate, with other options capped at 640x480 or lower, yielding substandard video quality unsuitable for anything but archival or casual use.

Neither offers microphone input or headphone monitoring, limiting audio control for more advanced videographers.
