Two Cameras, Two Eras: In-Depth Comparison of the Casio EX-100 and Samsung SL720

Over the years, I’ve spent countless hours testing digital cameras spanning pocket compacts to full-frame beasts. Today, I want to share a detailed comparison between two small sensor compacts that capture snapshots of two different moments in camera evolution: the Casio EX-100, released in early 2014, and Samsung’s SL720 (also known as PL70), a 2009 ultracompact. While both fall under the compact category, their ambitions, design choices, and performance profiles set them worlds apart despite similar sensor resolutions.

If you’re contemplating a compact for everyday photography, travel, or dabbling in multiple genres without lugging heavy gear, this comparison will provide firsthand insights from my rigorous shooting tests, lab evaluations, and real-world fieldwork. Let’s unfold how each camera stacks up for portrait, landscape, wildlife, and beyond, while diving deep into technical details you won’t find in most spec sheets.

First Impressions: Hands-On Design & Handling

Getting cameras comfortably into your hand is fundamental - and I always prioritize heavy hands-on time before passing judgment.

The Casio EX-100 feels solid and purposeful. Weighing in at 389 grams with dimensions of 119×67×50 mm, it strikes a balance between compact portability and ergonomic control. Its body is chunkier, with a sculpted grip design that gives confidence for steady handling during longer shoots. The super clear 3.5-inch tilting LCD is a joy to frame with; it’s large by compact standards and bright enough in outdoor shooting. In contrast, the Samsung SL720 is markedly smaller and lighter at just 168 grams and 92×61×23 mm, perfectly pocketable and discreet for street or travel. However, it feels more toy-like in hand, and fine operation with small buttons can test patience, especially for users with larger fingers.

Looking from above, the EX-100 presents an inviting control cluster, including dedicated exposure modes, shutter and aperture priority settings, and a clear layout that rewards quick adjustments on-the-fly - something any enthusiast will appreciate in dynamic shooting conditions. The SL720 sports minimal controls with many settings buried in menus, limiting flexibility and slowing down workflow.

In terms of build, neither camera is weather sealed or ruggedized, so they require careful handling in adverse environments. While I’ve tested both cameras in mild rain and dusty conditions, usage in heavy outdoors work calls for extra caution or protective gear.

Sensor Technology & Image Quality: The Heart of Your Photos

Both cameras utilize 12MP sensors, but this is where the lines begin to diverge sharply.

The EX-100 houses a 1/1.7-inch CMOS sensor measuring roughly 7.44×5.58 mm with a sensor area of 41.52 mm². CMOS, combined with Casio’s processing engine, allows responsive shooting, better noise management, and raw image capture - an essential feature for professional-grade post-processing control. The SL720’s CCD sensor is smaller at 1/2.3 inch (6.08×4.56 mm, sensor area 27.72 mm²) and lags behind in responsiveness and high ISO performance, partly due to older technology and the limitations inherent in CCD design.

Practically speaking, the Casio’s larger sensor yields greater dynamic range and cleaner images, particularly when shooting in low light or capturing subtle tonal gradients such as portraits with natural skin tones or landscapes at dusk. The SL720 holds firm in good light but struggles with noise and loss of detail above ISO 400, while the EX-100 remains usable up to ISO 3200 and beyond. The Casio’s support for raw files offers photographers much greater creative latitude - sharpening, exposure tweaking, and color grading without degradation.

I put both cameras through rigorous tests in varied light conditions, including shaded forests, overcast days, and dusk portraits. The Casio consistently produced files with richer textures, more vibrant yet accurate colors, and well-controlled noise - especially notable in portraiture where skin detail and subtlety matter.

Autofocus and Shooting Performance: Speed Meets Precision

When chasing spontaneity - from fleeting expressions to wildlife on the move - autofocus and continuous shooting capabilities make or break the experience.

The EX-100 features a 25-point contrast-detection autofocus system with face detection and a variety of AF modes including single, continuous, and tracking. While contrast-detection AF is generally slower than phase-detection systems found in DSLRs and mirrorless cameras, Casio implemented a responsive system that, in practice, locks focus quickly and maintains tracking reliably within its operational limits.

Samsung’s SL720 autofocus is more basic, offering single AF with contrast detection only, without face or tracking capabilities. This means it hunts noticeably in low light and can struggle with moving subjects - a significant limitation for wildlife, sports, or dynamic street photography.

Continuous shooting speeds are another large gap: the EX-100 can capture bursts at 30 frames per second, an unusually high speed for its class, useful for action-oriented photography or capturing fleeting smiles. The SL720 offers no meaningful continuous shooting mode, limiting its use primarily to static subjects.

Paint with Light: Exposure & Image Stabilization

Casio extended thoughtful exposure controls to the EX-100, offering aperture priority, shutter priority, and manual modes. This empowers photographers to creatively control depth of field or motion blur - a boon in landscape work or experimental macro and night photography. The SL720’s limited auto-only exposure behavior constrains creative flexibility significantly.

Image stabilization is built-in with the EX-100’s sensor-shift stabilization, which helps deliver sharper handheld photos at slower shutter speeds, a critical advantage for low-light shooting or telephoto ranges. Sony engineers have long championed this technology to counteract handshake. The SL720, unfortunately, lacks any stabilization, demanding faster shutter speeds or higher ISOs to avoid blur.

Screens and Interfaces: Framing Your Vision

The EX-100’s bright 3.5” tilting touchscreen differentiates itself sharply against the SL720’s fixed 2.7” LCD with only 230k dots resolution. While neither supports touch input, the EX-100’s “Super Clear LCD” vastly improves visibility in bright conditions and its tilt function helps when shooting from low or high angles - common in street photography or macro work.

Navigating menus on the Casio is intuitive and fast, with dedicated buttons enhancing usability. The SL720’s smaller screen compounded with menu complexity results in slower adjustments, frustrating when moments demand speed.

Lens Versatility: Zoom and Aperture in Daily Use

Lens characteristics often dictate shooting style and success.

The EX-100 offers a versatile 28-300mm equivalent zoom range with a bright, constant f/2.8 maximum aperture at the wide end, giving a generous reach for portraits, wildlife, or travel scenarios, plus excellent background separation from wide-open aperture. This long reach is remarkable in a compact offering.

By contrast, the SL720’s shorter 28-102mm (~3.6× zoom) covers essential wide to short telephoto but loses light rapidly towards the tele end (f/5.7 max aperture), limiting low light usage at longer focal lengths.

The Casio’s macro capabilities also shine, with minimum focusing distance down to 5 cm and sharpness maintained throughout the zoom range, lending itself well to flower photography or close-ups of textures.

In my shoots, the EX-100’s zoom allowed framing tightly on wildlife and distant subjects effectively, while maintaining crispness and smooth bokeh. The SL720’s lens performed adequately for everyday snapshots but lacked versatility or subject separation.

Battery Life and Storage: Endurance in the Field

Battery life is often overlooked until you’re stranded.

The Casio claims about 390 shots on a single charge - quite respectable given its features. In real-world use, especially during live view, video recording, and burst mode, expect fewer shots but still solid endurance for a day’s travel or event coverage.

Samsung’s SL720 lacks exact published endurance figures, but my experience showed moderate life; extended shooting days require spares.

Both accept standard SD formats, but Casio supports the latest SDXC cards allowing vast storage and fast write speeds, better suited for high-resolution JPEG plus raw workflows. Samsung’s compatibility includes SDHC and even MMC cards, good for casual use but limits maximum file size and speed.

Connectivity & Video Capabilities: Sharing and Storytelling

The EX-100 adds built-in Wi-Fi for quick image transfer - an invaluable feature by 2014 standards, enabling instant sharing or remote shooting via smartphone apps, significantly improving workflow for travel or social media savvy users.

The SL720 lacks any wireless connectivity, requiring manual USB tethering, a drag in today’s fast-paced sharing culture.

Video recording is another clear advantage with the EX-100 capable of full HD 1080p at usable frame rates, stabilized for smoother handheld footage. Samsung restricts video to low-res VGA and QVGA clips with dated MJPEG codec, suitable only for casual family clips.

Real-World Performance Across Photography Genres

Here’s where theory meets practice. Through years of shooting with both cameras in diverse situations, I synthesized their strengths and weaknesses.

Portrait Photography

Smooth skin tones and eye detail come mainly from sensor quality and lens speed. The EX-100 excels owing to large sensor and fast aperture, producing creamy bokeh and accurate colors that flatter faces naturally. Face detection autofocus aids precision and speed. The SL720’s image quality and focus lag make portraits a gamble.

Landscape Photography

Dynamic range and resolution are crucial. The Casio’s CMOS sensor captures more scene detail, maintains highlights and shadows better, and the zoom range helps frame sweeping vistas. The Samsung sensor and lens are adequate under perfect conditions but none-too forgiving of contrasty light or fine detail.

Wildlife & Sports Photography

Fast autofocus and burst shooting are king. The EX-100’s fast 30 fps burst, AF tracking, and long reach zoom are compelling for action and distant wildlife. The SL720’s slow AF and limited zoom make it unsuitable.

Street Photography

The SL720’s compact size and light weight edge it here for photographers valuing stealth and portability. The EX-100 is bulkier but quicker and more accurate for decisive moments, albeit more conspicuous.

Macro Photography

Casio’s close focus, sharp optics, and stabilization enable rewarding macro shots; Samsung performs basic close-ups but less sharpness and no stabilization hold it back.

Night/Astro Photography

Higher ISO usability combined with manual modes gives the EX-100 clear advantage for dim light or astrophotography. Samsung’s noise and exposure limitations restrict night shooting options.

Video Capabilities

Full HD stabilized video and Wi-Fi transfer make the EX-100 a multimedia tool, while Samsung’s low-res video is virtually legacy noise.

Travel Photography

The EX-100 edges when versatility and image quality matter most; the SL720’s small size suits extremely light packing or casual users on tight budgets.

Professional Work

Raw support, manual controls, and quality optics make the EX-100 usable as reliable backup or discrete secondary camera; the SL720 lacks this sophistication.

Sample Images: Visualizing the Difference

To see the distinctions, examine side-by-side high-resolution images captured under identical conditions.
