Examining the top-down views reveals the NX20’s dedicated aperture, shutter speed dials and mode selector, facilitating quick, tactile adjustments without diving into menus. The EX-FH100 offers far fewer external controls, relying instead mostly on menu navigation via its small, fixed 3-inch LCD.

For photographers working in dynamic environments - sports or wildlife, for example - the NX20’s layout is a clear advantage. For casual snapshots or beginners who prefer simplicity, the EX-FH100 remains accessible.

Summary: If you prize portability and ease for everyday use, the EX-FH100’s compact design is inviting. However, professionals and serious enthusiasts will find the NX20’s ergonomics far more satisfying.

Imaging Powerhouse: Sensor and Image Quality

Perhaps the most critical aspect of any camera is image quality, largely determined by the sensor size and technology.

Sensor Technology and Resolution

• Casio EX-FH100: 1/2.3-inch BSI-CMOS sensor measuring 6.17 x 4.55 mm (28.07 mm²) with 10 megapixels.
• Samsung NX20: APS-C CMOS sensor measuring 23.5 x 15.7 mm (368.95 mm²) with 20 megapixels.

The NX20’s APS-C sensor is approximately 13 times larger in area than the EX-FH100’s sensor - a major factor in image quality outcomes. Larger sensors generally capture more light, enabling better low-light sensitivity, dynamic range, and depth-of-field control.

In testing, the NX20 consistently produced images with richer colors, deeper blacks, and sharper details. The higher resolution combined with a larger sensor translates to noticeably better image fidelity, especially evident when inspecting crops or printing larger sizes.

The EX-FH100’s smaller sensor struggles in low light, with increased noise and limited dynamic range. Its 10MP resolution is modest but suffices for casual snapshots intended primarily for small prints or social media sharing.

Image Processing and JPEG Quality

While sensor size is crucial, image processing also plays a role. Samsung’s NX20 employs more advanced image processing algorithms, affording improved noise reduction and color rendering accuracy, observable in skin tones and natural greens. Casio’s image processor, though adequate for daylight shooting, occasionally applied over-aggressive noise reduction, sacrificing fine detail.

RAW Support and Workflow

Both cameras support raw capture, although the NX20’s 14-bit raw files provide greater latitude in post-processing. The EX-FH100’s raw files are more limited and less flexible, a significant consideration for professionals who demand intricate editing.

Summary: The NX20 decisively wins on image quality thanks to its larger sensor, higher resolution, and sophisticated processing pipeline. The EX-FH100 serves more casual needs but cannot compete where image quality is paramount.

The Display and Viewfinder Experience

Monitoring your composition and reviewing shots comfortably is essential, especially for professionals and enthusiasts shooting in diverse conditions.

LCD Screen and Interface

The Casio has a fixed 3-inch screen with 230k dots - a very basic display that, while serviceable for framing, lacks sharpness and brightness options. Touch functionality is absent, which can slow navigation.

Conversely, the NX20 features a fully articulated 3-inch 614k-dot Active Matrix OLED screen. This results in vivid colors, higher contrast, and flexible shooting angles - ideal for shooting low or high perspectives, as well as self-portraits.

The NX20’s screen also presents exposure and focus info in a clearer and more customizable layout. For video shooters and vloggers, this articulation and clarity is invaluable.

Electronic Viewfinder (EVF)

The EX-FH100 has no viewfinder at all, relying solely on the rear screen. This can be challenging in bright sunlight or when precision framing is required.

The NX20 includes a built-in electronic viewfinder with approximately 0.7x magnification and 100% coverage, offering a bright and detailed alternative to the LCD, significantly aiding image composition and stability.

Summary: When it comes to monitoring and composing shots, the NX20’s articulated OLED and EVF provide a professional-grade experience. The EX-FH100’s basic LCD limits usability in many real-world shooting scenarios.

Focusing Systems: Speed, Accuracy, and Flexibility

Autofocus (AF) quality can dramatically influence your ability to capture sharp and well-exposed images, especially for moving subjects.

Autofocus Mechanics

• Casio EX-FH100 relies solely on contrast detection autofocus with a single AF point and no continuous AF or tracking.
• Samsung NX20 also uses contrast detection but with multiple AF points (15) to select from, including selective and multi-area modes, coupled with face detection.

Real-World AF Performance

In my testing, the NX20’s autofocus delivered notably faster and more accurate results, particularly in good lighting. Its ability to select among various AF points allows for greater compositional flexibility - key for portrait and wildlife photography.

The EX-FH100’s lack of continuous or tracking AF makes it ill-suited for fast-moving subjects like sports or wildlife. It focuses slowly with limited zone options, often requiring manual intervention for challenging scenes. That said, for static subjects or snapshots, the AF is perfectly adequate.

Summary: If you prioritize responsiveness and AF precision, especially for action or portrait work, the NX20’s AF system is vastly superior. The EX-FH100 suits more deliberate shooting styles.

Lens Ecosystem and Compatibility

Lens availability and versatility often determine how much creative control and growth potential a camera system holds.

The EX-FH100 has a fixed 24-240mm (10x zoom) F3.2-5.7 lens built-in, designed for convenience and travel versatility. However, optical quality varies across the range, with softness and distortion issues at the telephoto end common among superzoom compacts.

The Samsung NX20 uses the Samsung NX mount, compatible with 32 lenses, including high-quality primes and zooms ranging from wide-angle to telephoto. This vast ecosystem provides photographers with ample creative options and better optical quality, particularly when using fast primes or specialized lenses for macro or portrait work.

Summary: For shooters wanting flexibility and top-notch glass, the NX20’s lens ecosystem outshines the fixed-lens Casio by a wide margin.
