In the realm of compact digital cameras circa 2009, two contenders catered to budget-conscious enthusiasts seeking portable solutions with moderate zoom capabilities: the Casio EX-S12 and the Samsung SL720 (also known as PL70). Both models feature 12-megapixel sensors packaged in slim bodies designed for casual and enthusiast users who prioritize pocketability without fully surrendering image quality.

This detailed comparison dissects their capabilities across core technical categories and photographic disciplines, showcasing real-world performance considerations essential for knowledgeable buyers seeking a principled choice based on usability and image outcome.

Design and Ergonomics: Comparing Portability and Handling

While both cameras approach compactness, subtle design choices influence operator comfort and control:

• Casio EX-S12 measures approximately 95 x 60 x 23 mm and weighs a mere 111 g.
• Samsung SL720 is marginally bulkier at 92 x 61 x 23 mm, with a weight of 168 g.

This slight bulk difference is perceptible in hand, with the EX-S12's lighter frame favoring effortless carry on extended excursions or travel. However, weight can confer improved handling stability, particularly when zoomed in or shooting handheld in low light.

Control layouts favor minimalism for both: neither camera sports manual dials or extensive custom key assignments, which significantly limits rapid in-field adjustments. There is no articulated touchscreen on either device, and a fixed 2.7-inch LCD screen with 230k-dot resolution serves as the primary user interface.

The EX-S12’s top view reveals a streamlined button cluster optimized for straightforward operation but lacking illuminated controls or dedicated manual exposure toggles. The SL720 offers an analogous button array but includes a dedicated self-timer button and rudimentary flash mode toggling, which slightly elevates ergonomics for more nuanced shooting scenarios.

In terms of sturdiness and weather resistance, neither model offers environmental sealing, waterproofing, dust proofing, shock proofing, or freeze proofing, aligning with their genre as casual compacts rather than rugged outdoor tools.

Sensor and Image Quality: Assessing Core Imaging Capabilities

Both cameras employ a 1/2.3-inch CCD sensor measuring just over 6 x 4.5 mm, with closely matched sensor areas:

• EX-S12: 6.17 x 4.55 mm (28.07 mm²)
• SL720: 6.08 x 4.56 mm (27.72 mm²)

Resolution stands identically at 12 megapixels (4000 x 3000 max resolution), each incorporating an anti-aliasing filter to prevent moiré patterns at the cost of some micro-detail sharpness.

CCD technology prioritizes image quality over high ISO performance but tends to exhibit more noise and lower dynamic range relative to later CMOS sensors. The maximum native ISO is capped at 1600 for both, with SL720 offering a slightly lower minimum ISO of 80, potentially aiding in daylight exposure control.

Neither supports RAW capture, significantly limiting post-processing latitude – a key drawback for professionals and advanced hobbyists who expect robust editing options. JPEG output is the sole deliverable, making in-camera image processing quality paramount.

Colors render cleanly under controlled lighting; however, both cameras struggle with noise and color shifts beyond ISO 400. Dynamic range capabilities are average and neither model employs advanced noise reduction algorithms common in contemporary designs.

Autofocus and Shooting Performance: Speed and Accuracy Insights

Autofocus across these two cameras relies exclusively on contrast-detection with single-shot AF modes:

• No manual focus override on Samsung SL720.
• Casio EX-S12 supports manual focus, albeit rudimentarily.

Neither camera provides face detection, eye detection, continuous AF, tracking, or multi-area AF modes. Focus point selection is fixed, and neither offers in-depth focus customization.

This results in slower focusing speeds in low contrast or low light environments, where hunting is commonplace. Live view AF is functional but not responsive to rapid subject shifts – a critical factor for action or wildlife photography.

Burst shooting or continuous shooting capabilities are not supported, eliminating these cameras as candidates for sports or wildlife shooters reliant on high frame rates to capture decisive moments.

Shutter speeds span:

• EX-S12: 1/2 to 1/2000 sec
• SL720: 8 sec to 1/1500 sec

The longer minimum shutter on the SL720 (8 sec) may restrict long exposure experimentation without bracketing or bulb modes, which neither camera supports.

Lens Performance: Zoom Range and Aperture Considerations

Both cameras use fixed zoom lenses with similar 3x optical zoom capabilities but differ in focal length and aperture range:

The SL720’s wider starting focal length (28mm vs 36mm) gives greater versatility for landscapes and architectural shots, while the EX-S12’s starting point at 36mm restricts field of view but may benefit portrait framing.

Maximum aperture of f/2.8 at wide end for both lenses allows decent low-light gathering capacity. The EX-S12’s narrower maximum aperture of f/7.9 at telephoto may compel higher ISOs or slower shutter speeds resulting in noise or blur, whereas the SL720 manages a brighter f/5.7.

Macro photography benefits from the SL720’s specified 5cm minimum focusing distance, enabling close-ups not feasible on the EX-S12, which lacks data or practical implementation for macro performance.

Display and Viewfinder: Visual Feedback for Composition

Both cameras rely solely on rear LCD for image composition, with no electronic or optical viewfinders, a common limitation for cameras in this class:

• Screen size: 2.7 inches
• Resolution: 230,000 dots
• Type: Fixed, non-touch

The similarity in screen size and resolution yields comparable user experiences, though none offer touch interaction or higher resolution displays that improve focus accuracy and preview sharpness.

Viewfinding options are absent, which detracts from usability in bright outdoor conditions or for those who prefer eye-level framing to minimize camera shake.

No articulated or tilting mechanism reduces compositional flexibility in low or high-angle shooting.

Video Capabilities: Modest Motion Capture

Video functions are limited and defined by maximum resolutions and codecs typical of entry-level compacts in the era:

The EX-S12’s ability to shoot HD 720p video is a notable advantage but is limited to 24 frames per second, reducing motion smoothness. The SL720 caps out at standard definition (640x480) and offers slightly higher frame rates.

Absence of in-body stabilization, external microphone jacks, or headphone monitoring restricts videographers from obtaining stable, well-audio-documented footage.

Battery Life and Storage: Practical Considerations

The cameras use proprietary lithium-ion battery packs:

• EX-S12: NP-60 battery; actual life unspecified by manufacturer.
• SL720: SLB-10A battery; exact battery endurance not published.

Users should anticipate modest capacities typical of ultra-compact cameras, translating into approximately 150-200 shots per charge under normal conditions.

Both cameras accept SD and SDHC memory cards, with the SL720 additionally compatible with MMC cards, broadening storage media options for users with legacy supplies.

Each camera offers an internal memory buffer, but size is minimal and primarily serves as emergency fallback.

Connectivity and Additional Features: Workflow Integration

Available wireless and interface options are sparse:

• Casio EX-S12 includes Eye-Fi wireless card compatibility, enabling some degree of wireless image transfer. It supports USB 2.0 and mini HDMI output for direct display.
• Samsung SL720 lacks wireless connectivity, but also offers USB 2.0 port; no HDMI output is present.

File transfer speed and compatibility rely primarily on USB 2.0 infrastructure, a baseline for the period. The lack of wireless or modern tethering options may constrain efficient workflow integration, especially for professionals or enthusiasts desiring rapid sharing.
