Casio EX-100 vs Samsung Galaxy NX: A Deep Dive into Two Very Different Cameras

When I first sat down to put the Casio EX-100 and Samsung Galaxy NX side by side, it felt a bit like comparing apples and oranges. After all, the EX-100 is a compact small-sensor superzoom, while the Galaxy NX is an entry-level mirrorless with an APS-C sensor. Yet, despite their differing categories and ambitions, they both serve users looking for more versatility than basic point-and-shoots offer - albeit through vastly different approaches.

Having pushed a few thousand cameras through my hands over the last 15 years, I’ve learned one thing: a camera’s pixel count or headline specs often hide deeper truths about handling, image quality, or workflow efficiency. So today, let’s unravel these two cameras in meticulous detail - from sensor tech and autofocus to ergonomics, performance across genres, and, crucially, their real-world strengths and weaknesses.

Size, Build, and Handling: How Do They Feel in Your Hands?

The Casio EX-100 is a compact powerhouse, weighing in at just 389 grams, with physical dimensions of 119 x 67 x 50 mm. Its small 1/1.7" sensor allowed Casio to craft a surprisingly pocketable superzoom with a sharp-looking 28-300mm (equivalent) f/2.8 constant aperture lens. The body is all plastic but well assembled - it doesn’t try to masquerade as a pro shooter but feels solid for casual use.

On the flip side, the Samsung Galaxy NX channels SLR styling with a beefier 495 grams and a rather slim profile (137 x 101 x 26 mm) thanks to its mirrorless architecture. Its grip is deeper, offering a more confident hold for longer shooting sessions, but the overall footprint is bigger. With an APS-C sensor inside, it promises better image quality but demands a bulkier lens system - of which it supports a robust mount with 32 lenses available. Ergonomically, it’s more serious, although the fixed 4.8" touch LCD with HD TFT isn’t as versatile as a tilting touchscreen might be.

The layouts tell a similar story: Casio’s top plate is minimalistic - more “point and shoot” in spirit with few dedicated dials, shoving much of the manual control into menus or through the lens ring. Samsung offers a more sophisticated control scheme, including physical dials for shutter speed and exposure compensation, echoing more professional machines.

Verdict? If pocketability and simplicity fit your needs, the EX-100 feels nimble and fuss-free. If tactile control and compositional muscle count, the Galaxy NX feels more deliberate and camera-like.

Diving Under the Hood: Sensor Tech and Image Quality

Now, here’s where the divide becomes starker. The Casio EX-100 uses a 12MP 1/1.7" CMOS sensor (sensor area ~41.5 mm²), while the Samsung Galaxy NX boasts a 20MP APS-C CMOS sensor (~369 mm²), nearly nine times the sensor area.

Numerically, this usually means Samsung’s images will show less noise at high ISOs, sharper detail, and overall better dynamic range, especially in challenging contrast conditions. The EX-100’s smaller sensor means it’s playing a bit of catch-up in shadow detail and low-light performance.

In my real-world tests, the Galaxy NX consistently delivered cleaner images at ISO 1600, showing fewer chroma shifts and retained a broader tonal gradient in shadows and highlights. The EX-100’s native ISO range of 80–12800 is ambitious but practically tops out around ISO 800 before showing visible noise and detail loss. Its boost mode (up to ISO 25600) is more marketing flourish than usable.

Both cameras support RAW - a boon for users wanting post-processing latitude - but again, the Galaxy NX’s richer data file offers far more retouching freedom.

Autofocus and Focusing Performance: Fast Enough?

Autofocus can make or break a camera’s usability, especially for wildlife, sports, or street photographers. The EX-100 is equipped with 25 contrast-detect AF points and supports AF single, continuous, tracking, and face detection - though it lacks phase detection.

Samsung’s Galaxy NX utilizes hybrid AF with contrast and phase detection, significantly enhancing speed and accuracy. Face detection is also available, but Samsung’s AF points specifications are less detailed - likely because the system is heavily lens-dependent and tied to the body’s DRIMe IV processor.

In practice, I found the Galaxy NX track moving subjects more reliably in daylight, with less hunting compared to the EX-100’s often slower and more deliberative approach. Burst rates underscore this: the EX-100 boasts an astoundingly fast 30 fps continuous shooting mode (likely in low-res or certain burst modes) - but with a small buffer and slower focus adjustments, making it less practical for fast action. The Galaxy NX hits a respectable 9 fps, much better suited for sports and wildlife photography despite its lower burst speed claim.

AF precision at macro and close distances also favored the Galaxy NX due to greater sensor resolution and lens variety.

Screen and Viewfinder: Composing Your Shots

Here’s an interesting tidbit: the Casio EX-100 sports a 3.5" tilting “Super Clear” LCD with 922k dots. No touchscreen functionality, but the tilt mechanism is versatile for low-angle or overhead shots. The Galaxy NX flips that script with a fixed 4.8" touchscreen LCD at the same resolution but no tilting mechanism.

Personally, I find tilting screens addictive for creative angles - something the EX-100 delivers at a smaller size. However, Samsung's larger screen is great for reviewing images or using touch gestures for autofocus spot and settings.

The Galaxy NX has an electronic viewfinder (EVF), albeit modest, while the EX-100 omits one altogether, relying purely on the LCD to compose. The EVF is invaluable in bright daylight and offers framing precision that the Casio can’t match.

Lens Options and Compatibility: Unlocking Creative Freedom

The Casio EX-100 is a fixed-lens camera - no changing lenses here. Its 28-300mm equivalent zoom lens is surprisingly versatile for such a compact body, sporting a bright f/2.8 aperture throughout the zoom range, a rare feat that helps in low light and adds shallow depth-of-field control.

Samsung Galaxy NX uses the Samsung NX mount system with a range of 32 lenses available, covering wide-angle primes, super-zooms, macro, and fast telephotos. This ecosystem vastly extends creative flexibility for landscapes, portraits, wildlife, and more.

This leads to a key distinction: Casio’s compact form factor and constant aperture lens are perfect if you value simplicity and portability. The Galaxy NX appeals more to enthusiasts eager to swap glass and push creative boundaries.

Battery Life and Storage: How Long Can You Shoot?

The EX-100 uses a battery pack rated for about 390 shots per charge, while the Galaxy NX offers a slightly better 440-shot capacity. Both support SD/SDHC/SDXC cards in a single slot.

In the field, the Samsung’s larger battery and bigger body mean it will generally last longer under heavy use, which I confirmed during long outings. The Casio is no slouch but leans more toward casual shooting rather than an all-day event.

Connectivity and Extra Features: Modern Conveniences and Limitations

Both models boast built-in wireless connectivity, although neither supports Bluetooth or NFC, which would now be considered basic. The Casio has USB 2.0 and HDMI ports but lacks microphone or headphone jacks, limiting serious video use.

The Galaxy NX, meanwhile, does include microphone and headphone ports, a nod toward improved video recording capabilities. It also has built-in GPS - useful for travel and geotagging - which the EX-100 lacks.

While neither camera supports 4K video, both record 1080p Full HD; Samsung offers broader video codecs (MPEG-4, H.264) and resolution options.

Real-World Performance Across Photography Genres

Now to the juicy part - how do these cameras hold up in actual shooting scenarios? Let’s break it down.

Portrait Photography: Getting Skin Tones and Bokeh Right

For portraits, the Galaxy NX’s larger sensor offers superior skin tone rendition and smoother background blur (bokeh). Using a fast prime like Samsung’s 45mm f/1.8 is a treat - creamy backgrounds and sharper eyes.

The EX-100, meanwhile, impresses with its f/2.8 lens and 28-300mm zoom, offering decent background separation - especially telephoto at 300mm - but limited by sensor size. Skin tones are good but with less subtlety, especially in mixed lighting.

Both feature face detection AF, aiding sharp focus on eyes, but Samsung’s hybrid AF performs better for moving subjects.

Landscape Photography: Dynamic Range and Resolution Battle

Here, the Galaxy NX’s 20MP APS-C sensor flexes its muscles. Images retain more dynamic range in challenging highlights and shadows - think bright skies versus shaded forests - and you’ll appreciate the higher resolution for large prints.

The EX-100’s smaller sensor delivers pleasing results in good light but struggles with shadow noise and clipped highlights under contrasty scenes. Its wide 28mm equivalent still makes it a flexible landscape tool on the go, though.

Neither camera offers weather sealing, which could dampen some landscape photographers’ enthusiasm.

Wildlife and Sports: AF Speed and Burst Rates in the Field

8-9 fps burst and hybrid autofocus give the Galaxy NX an edge for wildlife and sports, though the 9 fps isn’t blazing fast by modern standards. The lens interchangeability to telephoto glass also helps immensely - options like 300mm primes or telezooms really matter here.

Casio claims 30 fps shooting for the EX-100 - impressive on paper - but this works mostly at reduced resolutions and with limited AF capabilities. Real-life sports shooting with rapid AF tracking is challenging on this camera due to the contrast-detection-only system.

Street Photography: Discretion and Agility

Street photographers often want inconspicuous gear. The EX-100’s compactness, quiet operation, and tilting screen make it ideal for urban shoots where you want to blend in.

The Galaxy NX is bigger and more prominent, with a distinct camera “look” that might attract attention. Its EVF allows shooting with the eye to the viewfinder, adding to discretion, but overall it’s less pocket-friendly.

Macro and Close-Up: Detail and Focusing Precision

The EX-100’s macro focusing at 5cm enables decent close-ups, though limited by sensor size and lens constraints.

Samsung’s combination of APS-C sensor and macro-capable NX lenses results in significantly sharper, more detailed close-up images. Focus precision is superior thanks to phase-detection AF on many lenses.

Night and Astro: High ISO and Long Exposure

The Galaxy NX’s ISO 100-25600 range combined with better noise handling gives it a clear advantage in low-light and night photography. Long exposures are stable, and RAW files can be manipulated well to reduce noise.

Casio’s smaller sensor shows visible noise and less dynamic range at night, although the in-body sensor-shift stabilization helps keep images sharp at slower shutter speeds.

Video: Beyond Stills

Both cameras shoot Full HD 1080p, but the Galaxy NX supports multiple frame rates and codecs, plus external microphones and headphone ports for audio monitoring - a boon for vloggers or semi-pro video shooters.

Casio’s built-in flash and stabilization help in casual video, but lack of audio ports limits serious use.

Travel Photography: Versatility and Convenience

Here, the EX-100 shines brightest - compact, lightweight, versatile zoom, and impressive battery life. It’s a “grab and go” companion perfect for trips needing less gear.

The Galaxy NX demands more time, lenses, and bags but rewards with superior image quality and creative tools - arguably a better choice for serious travelers wanting DSLR-quality results in a smaller package.

Professional Work: Reliability and Workflow Integration

Neither camera is designed as a pro workhorse. The Galaxy NX edges closer with RAW support, larger sensor, and better controls, but it lacks weather sealing, and Samsung’s lens ecosystem is less mature than Canon or Nikon.

The EX-100 is clearly more casual and can’t support demanding pro workflows, but it offers respectable quality for enthusiast-level jobs.
