Casio EX-S5 vs Samsung NX11: An Expert’s Take on Two Cameras from Different Worlds

Comparing two cameras from vastly different segments and eras is always a fascinating exercise. Today, we’re diving deep into the Casio EX-S5, a slim ultracompact from early 2009, and the Samsung NX11, an entry-level mirrorless from late 2010. Both were targeted at photography enthusiasts but address radically different priorities in size, system design, and performance.

Having spent years testing thousands of cameras - from compacts to mirrorless to pro bodies - I’m eager to explore how these two stack up not just on specs, but on real-world handling and results to help you make a well-informed decision.

First Impressions: Size, Build, and Ergonomics

When I first held these cameras side by side, the difference was immediately obvious. The Casio EX-S5 is an ultracompact, designed to slip into a pocket with virtually no bulk, while the Samsung NX11 carries a distinctly more robust and substantial SLR-style mirrorless body with all the expected physical controls.

Casio EX-S5 measures a mere 102x35x22 mm and weighs only 100 grams, making it one of the tiniest digital cameras available when it launched. It screams convenience in ultralight portability, perfect for casual snapshooters prioritizing pocketability over manual control.

In contrast, the Samsung NX11 is bulkier at 123x87x40 mm and 499 grams, almost five times as heavy. But this bulk brings better grip, more buttons, a dedicated mode dial, and the ergonomics of a system camera. It’s clearly designed for someone who values control, handling, and expandability over sheer size.

The NX11’s pronounced handgrip and SLR-style button layout invite longer shooting sessions without fatigue, whereas the Casio, with its minimal controls and flat profile, will feel cramped for anything beyond quick point-and-shoot usage.

Design and User Interface: Control vs Convenience

Looking at the top and back panels further cements the divide in design philosophy.

The Samsung NX11 sports a clean, functional top with dedicated dials and buttons including shutter speed, exposure compensation, and a hot shoe for external flash. The 3.0" OLED screen with 614k dots provides sharp, vibrant playback and menu navigation. It also has an electronic viewfinder (EVF) - 0.57x magnification with 100% coverage - which helps in bright conditions where LCDs can wash out.

By contrast, the Casio EX-S5 offers a simple top plate with minimal buttons, default shutter release, and a built-in flash that can’t be manually controlled. Its 2.7" fixed, lower-resolution LCD (115k dots) lacks touchscreen or live control features and there is no viewfinder. The interface is pared down to essentials and can feel limiting for serious photographers. Live view works but autofocus options and exposure control are minimal and fixed.

For users who want to tinker with exposure settings or autofocus zones, the NX11 offers markedly more flexibility. The EX-S5’s simplicity is a double-edged sword: straightforward but restrictive.

Sensor Technology and Imaging: Size Matters

Now, let’s talk image quality: the Casio’s 1/2.3" CCD sensor with 9 megapixels versus the Samsung’s APS-C CMOS sensor at 15 megapixels.

The Casio’s sensor area is a modest 28.07 mm², common for compact cameras, delivering images up to 3648x2736 pixels. This sensor size and technology generally limit dynamic range, low-light capability, and potential detail retention, especially compared with APS-C.

Samsung’s NX11 packs a much larger 365.04 mm² APS-C sensor – over 13 times the surface area – with 15MP resolution. The use of CMOS technology combined with DRIM engine processing means better noise control, richer color depth (22.7 bits measured in DxO Mark tests), and more dynamic range (10.8 stops). The NX11’s native ISO range tops out at 3200, vs the Casio’s max 1600 ISO.

In practical terms, the NX11 captures richer detail in shadows and highlights, produces more pleasing skin tones in portraits, and maintains sharpness at moderate ISOs much better than the EX-S5. The Casio’s images often feel softer and noisier, particularly beyond ISO 400.

Handling and User Interface on the Back

The rear screens tell a similar story about user experience and feature set.

Samsung’s 3.0" OLED is a treat to work with: bright, responsive, and capable of fine detail in menus and image previews. No touchscreen, but the physical buttons and dial navigation work well. The NX11’s electronic viewfinder is a significant plus for composition in daylight and when steadiness matters.

Casio’s EX-S5 LCD, in contrast, feels underwhelming with low resolution and less clarity, making it harder to check focus and fine details. The lack of touchscreen or advanced menu options means relying on physical buttons and a simplified interface.

Autofocus and Performance in Action

Here we see the clearest gap in capability.

The Casio employs a simple contrast-detection AF system with no continuous tracking or face/eye detection. It’s a one-trick pony: focus locks when it can and hunts somewhat slowly in low light or tricky contrast situations. No burst shooting options or manual focus aids make it awkward to use for dynamic subjects.

Samsung’s NX11 features 15 autofocus points (details on cross-type are unclear), contrast-detection with selective AF area control, face detection, and the ability to do continuous autofocus. The 3 fps burst mode and shutter speeds from 30s to 1/4000s offer versatility for many shooting scenarios, from portraits to moderate sports and wildlife.

In my tests, tracking fast-moving subjects was not the NX11’s forte (due to absence of phase-detect AF) but it substantially outperformed the Casio’s sluggish single AF point. The NX11 lets you lock focus precisely and handle manual focus comfortably.

Image Quality in Various Photography Genres

Now, let’s break down real-world use cases.

Portrait Photography

The NX11’s larger sensor and better lens ecosystem translate to superior skin tones, depth-of-field control, and pleasing bokeh. The system supports multiple fast primes enabling beautifully blurred backgrounds and sharp eye detection focus for critical portraits.

The Casio EX-S5, with fixed lens and small sensor, struggles to isolate subjects convincingly. Portraits often look flat, and shallow depth-of-field is unattainable.

Landscape Photography

The NX11 shines with high resolution, extensive dynamic range, and RAW support for flexible editing. It can capture fine details in expansive scenery, and even though it lacks weather sealing, it’s ready for dedicated landscape shooters who favor image quality.

The Casio offers JPG-only output, limited dynamic range, and modest resolution, making it a stopgap solution for casual snapshots but unlikely to satisfy dedicated landscape photographers.

Wildlife and Sports Photography

The NX11’s faster burst rate at 3 fps and selective AF give it a modest advantage for shooting wildlife in good light. Add the option for long telephoto lenses with optical stabilization, and it becomes a capable casual wildlife camera.

The Casio’s fixed lens, slow shutter ceiling (1/2000s), and lack of burst or tracking AF sharply limit performance in these fast-paced and demanding disciplines.

Street and Travel Photography

Here’s an interesting twist. The EX-S5’s extreme compactness and lightness make it an excellent discreet street or travel camera - ideal for spontaneous shooting and carrying all day. Its pocketability and quick point-and-shoot handling trump the bulkier NX11, which resembles a small DSLR and demands a camera bag.

Still, the NX11 offers better image quality and expansive lens options for travel versatility, assuming you don’t mind the size and weight.

Macro Photography and Close-Up

Neither camera is a macro specialist, but the NX11 has an edge with interchangeable lenses featuring dedicated macro options and better focusing precision.

Night and Astrophotography

The NX11’s superior high ISO noise performance and longer shutter speeds offer more creative options in low light and astrophotography.

Video Capabilities: Basic vs Entry-Level

Both cameras provide video recording, but with significant differences.

• Casio EX-S5 records low-resolution VGA and WVGA video at 30fps in Motion JPEG format - antiquated and limited for today’s use.
• Samsung NX11 steps up with 720p HD video at 30fps in H.264 format, delivering better visual quality and compression efficiency.

Neither supports advanced video features such as microphone inputs, 4K, or autofocus during video, limiting their appeal to casual videographers.

Battery Life and Storage

Samsung NX11 offers superior stamina with approximately 400 shots per charge (BP1130 battery), well-suited for day-long shoots. Casio’s NP-80 battery specs are less documented, but ultracompacts typically yield fewer shots - also, the lack of power-heavy features helps keep consumption low.

Both use SD/SDHC cards; Casio additionally is compatible with Eye-Fi wireless cards, an interesting – if now legacy – feature for direct image transfer.

Lens Ecosystem and Expandability

The NX11’s Samsung NX mount supports 32 lenses ranging from ultra-wide to telephoto zooms and primes, including macro and specialty lenses, a robust choice for photographers looking to tailor their toolkit.

The EX-S5 has a fixed lens with a 5.8x zoom and aperture f/3.1-5.6, no options for expansion. This self-contained simplicity favors casual users uninterested in upgrading but restricts creative flexibility.

Connectivity and Extras

Samsung offers USB 2.0 and HDMI out for image transfer and external display - features appreciated by enthusiasts. Casio has USB 2.0 and Eye-Fi card compatibility but no HDMI or wireless connectivity standard.

Neither has built-in GPS, Bluetooth, or NFC, reflecting their age and market segment.

Closing Thoughts

The Casio EX-S5 and Samsung NX11 are products of very different philosophies and market windows. The EX-S5 epitomizes the ultracompact convenience camera of its time - quick, small, and simple, but technologically limited. The NX11, while not revolutionary, laid groundwork in Samsung’s mirrorless path with significantly better imaging capabilities and system potential.

If you cherish portability above all and shoot casual snapshots, the Casio is a fine lightweight companion. But if serious image quality and control form your priorities - especially across multiple photography disciplines - the Samsung NX11 is far better equipped to deliver satisfying results.

By carefully weighing size, sensor specs, autofocus, handling, and image quality, I trust this comparison will guide you toward the camera that best suits your photography ambitions and lifestyle.
