Casio EX-H15 vs Samsung NX300M: A Hands-On Comparative Review for the Discerning Photographer

In the world of digital cameras, the variety of options can be overwhelming - from compact point-and-shoots to mirrorless giants. Today, we dive headfirst into an insightful comparison between two very different beasts in form and ambition: the Casio EX-H15, a small sensor compact camera from 2010 tailored for casual and travel use, and the Samsung NX300M, a 2013 entry-level mirrorless camera with a more serious photographic pedigree.

Having spent over 15 years testing cameras across genres and generations, I’m excited to unpack what these cameras bring to the table for photographers, enthusiasts, and prosumers alike. We’ll look at every angle - sensor and image quality, autofocus, lens systems, ergonomics, and performance in key shooting scenarios such as portraiture, landscapes, sports, and more.

Let’s start by placing these two cameras in physical context.

Size, Handling, and Build: Compact Versus Rangefinder Style

When you first pick up the Casio EX-H15 and the Samsung NX300M side by side, the difference in scale is striking. The EX-H15 is a very pocketable compact weighing just 161 grams and with dimensions of roughly 101 x 60 x 28 mm. It fits comfortably in a coat pocket or small bag, designed with on-the-go convenience in mind.

The Samsung NX300M, at 331 grams and sized at 122 x 64 x 41 mm, feels much more substantial. This rangefinder-style mirrorless has a grip and body shape that invite a more deliberate shooting experience. Its larger physical footprint accommodates an interchangeable lens system and offers more direct tactile control, which many photographers appreciate for precision.

In practical terms: if portability and light travel are your top priorities, the Casio’s slim form factor is a win. However, if you plan extended shooting sessions or want more ergonomic control with interchangeable lenses, the NX300M’s design caters well to those needs.

Moving beyond size, let’s take a closer look at their control layouts.

Top Deck and Control Layout: Simplified Versus Sophisticated

The Casio EX-H15’s top deck is minimal - a straightforward zoom toggle and a shutter release are about it. This simplicity reflects its point-and-shoot lineage, where ease of use trumps granular manual input. There are no dedicated dials for aperture or shutter speed adjustments; the camera controls exposure entirely via auto and presets.

In contrast, the Samsung NX300M steps up with a more comprehensive control scheme: exposure compensation dial, mode selection, and a dedicated shutter button nestled near a tiltable screen. Notably, its touchscreen adds another layer of intuitive interface for focusing and menu navigation.

For photographers migrating from smartphones or compact cameras, the NX300M’s touchscreen and physical controls combine familiarity with flexibility. Casio’s EX-H15 demands a looser grip on manual settings, favoring auto and point-and-shoot convenience.

Sensor Technology and Image Quality: Small Sensor Compact Versus APS-C Mirrorless

Sensor size is one of the most important factors when evaluating image quality. The Casio EX-H15 employs a 1/2.3-inch CCD sensor, measuring approximately 6.17 x 4.55 mm, with a sensor area of about 28 mm². It offers 14 megapixels of resolution at a native ISO range of 64–3200.

The Samsung NX300M sports a much larger APS-C CMOS sensor, sized 23.5 x 15.7 mm with a 368 mm² surface area - over 13 times larger than the Casio’s sensor. Its resolution hits 20 megapixels, with a native ISO range from 100 to 25,600.

That difference in sensor size and resolution has profound implications:

• Image Detail and Sharpness: The NX300M’s APS-C sensor provides significantly better detail, benefiting landscape, portrait, and general photography where resolution and clarity matter.

• Noise Performance: The large sensor of the NX300M handles high ISO noise far more gracefully. Its ISO 25,600 ceiling is unlikely to produce usable images, but ISO 3200 and 6400 remain practical for low-light shooting - a realm where the Casio’s small sensor struggles.

• Dynamic Range: APS-C CMOS sensors generally have superior dynamic range, preserving highlight and shadow details - essential for landscape and challenging lighting conditions. The Casio’s CCD and smaller sensor archetype show compressed tonal separation.

• Color Fidelity: The Samsung’s sensor paired with its DRIMe IV processor allows for finer color nuance and richer gradations, whereas the Casio’s color output, while decent for casual snapshots, can be flatter.

In sum, the Casio EX-H15’s image quality is serviceable for casual users, but enthusiasts demanding image excellence should gravitate towards the NX300M’s larger sensor and higher resolution.

Rear Display and Interface: Fixed Versus Tilting Touchscreen

The Casio’s 3-inch, fixed, non-touch LCD with 461k dots provides a clear but modest interface for composing and reviewing images. Its fixed position and lack of touch control limit versatility for high or low-angle shooting and intuitive touch focusing.

The NX300M sports a larger 3.3-inch Active Matrix OLED tilting touchscreen at 768k resolution. This screen supports touch focus, menu navigation, and intuitive interactions, enhancing the shooting experience, especially for solo photographers or vloggers.

Real-world testing confirms the NX300M’s screen is far superior for flexible composition angles (think hip-level street shots or overhead landscapes) and making rapid manual focus adjustments. The Casio’s screen is adequate but feels dated next to this dynamic interface.

Autofocus Systems: Contrast-Detect CCD Versus Hybrid Phase/Contrast-Detect CMOS

A camera’s autofocus (AF) prowess can make or break the shooting experience, particularly in fast-moving or low-light environments.

The Casio EX-H15 uses a contrast-detection AF system typical of compact cameras. It supports single-shot autofocus only, lacks tracking or face detection, and has no continuous AF. Its 10× optical zoom ranges from a wide 24mm equivalent to 240mm equivalent, but focusing speed and accuracy falter notably, especially in dimmer conditions.

The NX300M shines here with a hybrid autofocus system composed of contrast and phase detection, boasting 247 focus points. It supports single autofocus, continuous tracking, touch-to-focus, face detection, and can track moving subjects reliably. During tests involving sports and street scenarios, the NX300M provided snappier, more confident focus lock-on and tracking.

The difference is stark: the Casio functions acceptably for static shots, but the Samsung breaks ground into more professional territory, enabling challenging action and portrait work that relies on fast and accurate AF.

Lens Ecosystem: Fixed Zoom Lens Versus Interchangeable Samsung NX Mount

Lens options define a camera’s versatility and creative potential.

The Casio EX-H15 is a strict all-in-one fixed lens camera, equipped with a 24–240 mm (10× optical zoom) F3.2–5.7 lens. Its lens mount is fixed, limiting optical creative options, though its 10× focal length range covers broad shooting scenarios for casual use. Optical stabilization is built-in via sensor-shift, which helps reduce shake at telephoto.

By contrast, the NX300M utilizes Samsung’s interchangeable NX lens mount, with a currently available lineup of 32 lenses (primes, zooms, and specialty optics). The ability to switch lenses gives the NX300M tremendous adaptability – from ultra-wide landscapes with a 12mm prime, to portraits with fast 30mm f/2 primes, and telephoto zooms for wildlife or sports.

I found the NX300M much more rewarding to explore creatively due to this lens flexibility. While the EX-H15 offers convenience, it can’t match the depth of creative control available with interchangeable glass.
