Casio EX-Z550 vs Samsung NX11

Casio EX-Z550 vs Samsung NX11: A Hands-On Camera Comparison for Enthusiasts and Pros

As someone who has tested thousands of cameras over the last 15 years - from rugged compacts to cutting-edge mirrorless systems - I’m often asked how entry-level or ultracompact models hold up in real-world shooting across genres. Today, I take a close look at two cameras from the early 2010s: the Casio EX-Z550 ultracompact, announced in January 2010, and the Samsung NX11 entry-level mirrorless, which hit the market nearly a year later. Though different in design philosophy and target users, comparing these two side-by-side offers valuable insights on how camera technology and user expectations evolved in the early days of affordable digital photography.

This isn’t just a spec sheet rundown; I bring genuine field testing, technical analysis, and practical advice to help you decide which camera might suit your photography style and budget. We’ll examine every critical aspect - from sensor quality to ergonomics, autofocus to video, and beyond - across major photographic disciplines.

First Impressions: Size, Handling, and Physical Design

Before I even fired up these cameras, their contrasting form factors told a story about who they’re designed for.

The Casio EX-Z550 is a true ultracompact: tiny, pocketable, and built for convenience without the bulk. In my hands, its minimalistic controls mean fast access to point-and-shoot ease. The Samsung NX11, on the other hand, clearly aims at users craving more manual control and interchangeable lenses, sporting an SLR-style body that feels serious and solid - still quite compact for a mirrorless APS-C but much bigger and heavier than Casio’s offering.

Physically, the EX-Z550 measures just 99 x 53 x 20mm and weighs a mere 143 grams. It fits comfortably even in small pockets, perfect for travel or casual street photography. Conversely, the Samsung NX11's dimensions are 123 x 87 x 40mm, weighing in at around 499 grams - a noticeable difference in heft and grip.

Handling-wise, the NX11’s deeper grip lends itself better to stable shooting, especially with telephoto or larger lenses. The EX-Z550 feels nimble but can feel a bit cramped, especially if you’re coming from DSLR or mirrorless bodies with dedicated dials.

Top-Down Controls: Who’s in Charge Here?

Physical buttons and dials often make or break a camera's ease of use in dynamic shooting environments.

Looking at the top panels, the NX11 offers a rich layout resembling traditional SLR cameras, including a mode dial supporting shutter priority, aperture priority, and manual exposure modes alongside the automatic and program options. There’s also a dedicated exposure compensation button and a standard hot shoe for external flashes.

The EX-Z550, true to its ultracompact nature, keeps controls minimal with mostly default automatic exposure and limited manual override options. No shutter or aperture priority mode is available, and exposure compensation is missing entirely - highlighting its intent as a casual shooter’s companion rather than a creative tool.

If you enjoy tinkering with exposure settings on the fly, NX11’s layout is far more accommodating. The EX-Z550, while straightforward, will frustrate users wanting creative flexibility.

Sensor Technology and Image Quality: The Heart of the Matter

Testing both cameras side by side under controlled lighting and real-world scenes was enlightening.

The EX-Z550 packs a modest 1/2.3-inch CCD sensor with 14MP resolution; this sensor size is common in compact cameras but inherently limits dynamic range and low-light performance. The sensor area here is just 28.07 mm², which is quite small compared to modern standards.

The NX11, in contrast, leverages a much larger APS-C CMOS sensor measuring 23.4x15.6 mm, or approximately 365mm², with a 15MP resolution. This sensor size is a game-changer, delivering superior image quality, especially in low light, better control over depth of field, and richer color rendition.

In practical terms, during landscape shoots I was able to extract more nuances in shadow and highlights from NX11’s RAW files (the Casio doesn’t support RAW, limiting post-processing flexibility). Zooming into both cameras’ 100% crop reveals the NX11's output to be sharper, with less noise at ISO 800 and beyond. The Casio's performance deteriorates rapidly above ISO 400, with considerable chroma noise and loss of detail.

Screen and User Interface: Seeing Your Image

Bright sunlight and angle of view matter when composing and reviewing shots.

The Casio sports a 2.7-inch fixed LCD with 230k pixels - a relatively low resolution by today’s standards. The Samsung NX11 has a larger 3-inch active matrix OLED screen with 614k pixels, delivering more vibrant colors and better contrast.

From a usability perspective, the NX11's screen significantly improves manual focusing and menu navigation. The EX-Z550’s screen can be challenging in direct sunlight due to its lower brightness and resolution, leading to guesswork unless you’re indoors or shading the display. Neither camera offers touchscreen control, which is expected for their era.

Optical Systems and Lens Options: Flexibility vs Convenience

Your choice of lenses often dictates photographic creativity more than the camera body itself.

The EX-Z550 has a fixed zoom lens with a 26-104 mm equivalent focal range (4x zoom) and max aperture from F2.6 to F5.9. While it covers wide-angle to moderate telephoto for everyday shooting, you are locked into this lens and there’s no option for upgrades or specialty optics.

The NX11 features the Samsung NX mount, supporting dozens of lenses (32 officially listed back then), giving photographers choices from wide primes to telephoto zooms, macro, and fast apertures. Paired with its APS-C sensor, this system unlocks creative potential for portraits, wildlife, macro, or landscapes.

Autofocus and Shooting Performance: Speed and Accuracy in Action

Years of testing have taught me autofocus systems can make or break certain genres like wildlife and sports photography.

The EX-Z550 uses contrast detect AF only, with a single focus point and no face or eye detection. It lacks continuous AF tracking or rapid burst modes. The NX11 steps it up with 15 contrast detection autofocus points, face detection for portraits, and continuous AF for subject tracking, though without phase detection autofocus which limits speed compared to modern mirrorless.

In shooting bursts, the Casio doesn’t specify continuous shooting, effectively limiting action shots. The NX11 manages 3 fps burst rate, modest but sufficient for casual sports photography.

In practice, I found the NX11’s AF more reliable and snappier, especially in decent light. The Casio struggles with accuracy and hunting in lower illumination or when subjects move unpredictably.

Versatility Across Photography Genres

Let’s talk real use cases - how do these cameras fare at portrait, landscape, street, sports, wildlife, macro, night, and travel photography?

Portraits:
The NX11, benefitting from the APS-C sensor and available fast prime lenses, produces smoother bokeh and truer skin tones with face detection AF helping lock focus on eyes. The Casio’s small sensor and fixed lens mean flatter images with less subject-background separation; skin tones appear slightly less nuanced due to limited color depth and processing.

Landscapes:
NX11 excels with better dynamic range and detail retention in RAW, capturing intricate scenes effectively. The EX-Z550’s smaller sensor and JPEG-only output limit post-processing latitude but can suffice for casual snaps.

Street Photography:
EX-Z550's compact size and discreet look offer advantages for candid moments in crowds - no intrusive size or weight, but slower AF can miss fleeting expressions. NX11 is bulkier but delivers better image quality; photographers comfortable with its size will be rewarded.

Sports and Wildlife:
NX11 is better suited due to its faster shutter speeds (up to 1/4000s), moderate burst speeds, and AF flexibility. EX-Z550's max shutter speed tops at 1/2000s and lacks any burst shooting, making it ill fit for fast action.

Macro:
Neither camera specializes here, but NX11's lenses support closer focusing distances and more precise manual focus, ideal for flower or insect photography over the Casio’s limited fixed optics.

Night and Astro:
The Samsung’s higher ISO performance is a massive advantage when shooting stars or night scenes; the Casio's noise becomes prohibitive beyond ISO 400.

Video:
Both offer at most 720p video, but the NX11 records using efficient H.264, while the Casio uses Motion JPEG, leading to larger files and reduced quality. Neither has microphone inputs, limiting audio customization.

Travel Photography:
Casio is ultra-portable but limited in creative control. NX11 provides versatility and image quality at the cost of size and weight; battery life favors NX11 with approx. 400 shots compared to unknown on the Casio.

Durability, Battery, and Connectivity

Neither camera boasts environmental sealing or ruggedness, meaning they require careful handling outdoors. The NX11’s battery life rating is quite respectable for its class.

Connectivity-wise, Casio uniquely supports Eye-Fi memory cards allowing wireless transfer - a neat feature when it worked - but lacks Bluetooth or Wi-Fi. Samsung NX11 offers HDMI output but no onboard wireless. USB 2.0 is standard for both.

Cost and Value in Context

Price is often the deciding factor for enthusiasts on a budget.

At their launch, the Casio EX-Z550 priced around $149 represented an affordable pocket camera, perfect for casual photographers seeking convenience. The Samsung NX11, at approximately $626, positioned itself as a beginner mirrorless with serious ambitions, targeting users ready to step up image quality and system flexibility.
