When choosing a camera, especially within the complex landscape of 2010s-era models, enthusiasts and professionals alike face a plethora of options that balance sensor technology, ergonomics, and usability in often unconventional ways. This detailed comparison between the Casio EX-ZR700 and the Samsung NX100 delves beyond mere specifications - offering readers a meticulous appraisal based on sensor performance, autofocus competency, photographic versatility, and video capabilities, informed by extensive hands-on testing protocols honed over years of rigorous camera review.

These two cameras cater to notably different segments yet occasionally overlap in appeal: the EX-ZR700 representing Casio’s compact, superzoom point-and-shoot approach with an 18x zoom lens on a small sensor; and the NX100 marking Samsung’s early entry into the mirrorless interchangeable lens market, boasting a significantly larger APS-C sensor but a more traditional body. Wading beyond their surface-level mechatronics reveals their strengths and compromises in real-world shooting across all major photography types.

Seeing and Handling: Size, Ergonomics, and Control Layout

Before engaging the sensors and software brains of these systems, the physical feel and operational ergonomics can influence the shooting experience profoundly, particularly for handheld or fast-action work.

The Casio EX-ZR700 is a compact camera with dimensions of 108 x 60 x 31 mm and weighing 222 grams, making it pocketable and travel-friendly. Its fixed lens with a formidable 18x optical zoom effectively makes it a travel all-in-one solution. However, its compactness also constrains grip size and button ergonomics, resulting in limited manual control surfaces and no electronic viewfinder (EVF) to aid composition in bright conditions.

In contrast, the Samsung NX100 inhabits a traditional rangefinder-style mirrorless body measuring 120 x 71 x 35 mm and weighing a heftier 282 grams due to its metal chassis and interchangeable lens mount system. Dedicated dials and buttons lend the NX100 more tactile control for exposure, aperture, and ISO adjustments - a noteworthy advantage for photographers who prefer direct hardware interfaces over menu diving.

While both cameras possess non-touch displays recessed on their rear panels, the NX100’s 3.0-inch AMOLED screen (614k dots), despite lower resolution, offers crisper colors and better contrast for image review than Casio’s 3-inch Super Clear TFT LCD (922k dots). The EX-ZR700’s lack of an EVF and smaller control interface flags a design ethos centered on portability rather than professional operation.

In summary, ergonomically, the NX100 provides an interface more conducive to intentional photography workflows, favoring enthusiasts who demand manual control, whereas the EX-ZR700 prioritizes compact convenience and zoom range - despite constrained handling.

Sensor and Image Quality: Fundamental Technical Foundations

At the heart of any camera’s image-making lies its sensor - its size, resolution, and processing influence virtually every aspect of image quality, from detail rendition and dynamic range to low-light behavior.

The EX-ZR700 utilizes a 1/2.3-inch type CMOS sensor measuring approximately 6.17 x 4.55 mm (28.07 mm²) with a 16-megapixel resolution, fairly typical for compact superzoom cameras of its era. Conversely, the NX100 sports a significantly larger APS-C sensor (23.4 x 15.6 mm, 365.04 mm²) with 15 megapixels, positioned firmly in the range of interchangeable lens mirrorless cameras.

This sensor size disparity profoundly impacts technical image quality metrics:

• Dynamic Range: NX100’s APS-C sensor offers a tested dynamic range advantage of roughly 10.7 EV stops, facilitating capture of rich tonal gradations in high-contrast scenes such as landscapes and outdoor portraits. The EX-ZR700’s smaller sensor yields more limited latitude, susceptible to highlight clipping and shadow noise.

• Color Depth: The NX100 measures around 22.6 bits of color depth per channel, markedly higher than what the compact Casio’s sensor can achieve, resulting in more nuanced color transitions and better skin tone rendering.

• High ISO and Noise Behavior: NX100’s native ISO range extends to 6400, while EX-ZR700 handles ISO up to 3200. Real-world tests demonstrate the NX100 maintains respectable noise levels up to ISO 1600/3200, but the Casio’s noise rises sharply beyond ISO 400, limiting its usefulness under dim ambient lighting.

• Detail and Resolution: Although both cameras feature roughly similar megapixels (~15-16 MP), the NX100’s pixel pitch benefits from the larger sensor area, rendering finer detail retention, especially under adequate lighting.

In summary, from a raw image fidelity perspective, the NX100 clearly outpaces the EX-ZR700, especially in terms of tonal range and low-light resilience - a critical delimitation for serious applications such as landscape, portraiture, and professional work.

Autofocus Systems Put to the Test: Precision and Speed

Autofocus remains a vital determinant of camera performance, particularly across wildlife, sports, and fast-moving subjects.

The Casio EX-ZR700 employs contrast-detection AF with face detection enabled, a relatively modest feature set for autofocus precision, and supports “aftracking” (continuous autofocus), but notably lacks phase-detection autofocus and advanced tracking.

The Samsung NX100 advances slightly with a contrast-detection AF system utilizing 15 focus points, including multi-area and selective modes. While also devoid of phase-detection AF, it compensates with better manual focus usability via lens control rings and optional EVF focus magnification.

In practical shooting at a controlled test environment simulating wildlife and sports subjects:

• EX-ZR700’s autofocus tends to hunt in low contrast or low light, lagging behind faster mirrorless counterparts, limiting burst potential with only 3 fps shooting speed. Its fixed lens also restricts telephoto reach efficiency, despite extensive zoom.

• NX100, while similarly capped at 3 fps, demonstrates more reliable autofocus lock, especially with prime lenses or fast zooms, though tracking moving subjects remains challenging given the absence of continuous AF tracking sophistication.

Neither camera is ideal for rigorous wildlife or sports action photography; however, NX100 affords better manual override and lens selection diversity, essential for demanding AF scenarios.

Zoom and Lens Ecosystem: Flexibility vs. Specialization

Zoom reach and lens interchangeability fundamentally shape a camera’s versatility and suitability for various photographic disciplines.

The Casio EX-ZR700, fixed-lens with 25-450 mm (equivalent) optical zoom delivering 18x reach, excels strictly as an all-in-one superzoom compact, suitable for travel, street, and casual wildlife photography without lens changes. Its sensor-shift image stabilization helps stabilize handheld shots at telephoto lengths, a definite plus under real-world conditions.

On the other hand, Samsung’s NX100 utilizes the Samsung NX lens mount, offering access to 32 native lenses ranging from ultra-wide to telephoto primes and zooms, though the native lens ecosystem is less extensive than Canon, Nikon, or Sony counterparts. Notably, the APS-C sensor paired with quality NX lenses allows for superior bokeh control and image sharpness.

For macro photography, the NX100 benefits from dedicated macro lenses affording better magnification and focusing precision compared to the fixed macro mode of the EX-ZR700, which allows close-ups down to 5 cm - a respectable feature for compact cameras but lacking the depth and finesse achievable with specialized lenses.

Hence, the EX-ZR700 provides unmatched convenience and zoom flexibility in a pocketable form factor, whereas the NX100 caters to photographic specialization and optical quality through lens selections at the expense of bulk and complexity.

Performance in Portraiture and Skin Tone Rendering

Portrait photography demands cameras that deliver smooth skin tones, flattering color reproduction, and attractive bokeh to isolate subjects effectively. We evaluated both cameras under standardized portrait studio lighting as well as natural light scenarios.

The Casio EX-ZR700, while capable of face detection AF, suffers due to its small sensor size producing inherently deeper depth of field and reduced background blur, limiting subject separation. Its JPEG engine delivers decent skin tone rendering but tends towards over-sharpening and minor color shifts, a known artifact of many compact cameras.

The Samsung NX100’s larger sensor coupled with wide-aperture NX lenses creates significantly more pronounced bokeh effects, yielding superior subject isolation and creamy background blur. Its raw output capability also allows skilled users extensive latitude to manage skin tones and color grading in post-processing, a critical advantage that the Casio lacks due to absence of raw support.

Eye detection is rudimentary on both models, not supporting the sophisticated face and eye AF typical in later mirrorless cameras; however, NX100’s manual focus assist features provide practical compensation.

Overall, for portraits - especially those leveraging artistic depth of field and high fidelity skin tones - the NX100 maintains the clear upper hand.

Scenic and Landscape Capabilities: Resolving Details and Endurance

Landscape photographers prioritize resolution, dynamic range, ruggedness, and weather sealing to capture grand vistas and subtle lighting.

Although neither model offers environmental sealing, the NX100’s APS-C sensor naturally acquires greater detail resolution and broad dynamic range, crucial for landscapes featuring shadow and highlight interplay. Its native ISO 100 to 6400 range provides flexibility for varied lighting conditions, though best results stay under ISO 800 to preserve detail.

By contrast, the EX-ZR700’s small sensor and limited dynamic range challenge preservation of fine textures and tonal subtleties in scenes with extreme sky-to-shadow contrasts. The camera’s sensor-shift stabilization assists handheld shooting but the fixed lens’ maximum aperture range (f/3.5-5.9) restricts low light usability.

Practically speaking, serious landscape photographers would find the NX100's raw shooting and post-processing options invaluable for print or exhibition work, while the EX-ZR700 serves casual travel shots without specialist expectations.

Wildlife and Sports Shooting: Speed and Tracking

The dual demands of wildlife and sports photography - rapid autofocus tracking, high frame rates, and telephoto reach - often reveal each camera’s critical limitations or merits.

• The EX-ZR700’s built-in 18x zoom lens at 450 mm equivalent provides impressive reach for a compact, but its autofocus speed and continuous shooting at 3 fps barely suffice for slow-moving animals or casual sports, compounded by limited tracking algorithms and no phase-detection AF. Its sensor size hinders image quality, especially under rapidly changing light.

• The Samsung NX100 excels moderately in these domains when paired with fast telephoto NX lenses. Its manual focus aids tracking difficult subjects, though it lacks modern autofocus tracking sophistication and silent electronic shutter options that contemporary sports cameras offer. Frame rate parity with Casio’s camera caps burst potential.

For serious wildlife and sports shooters, neither camera is ideal, but the NX100 offers more control potential and higher image quality when lens-equipped appropriately.

Both cameras are constrained by moderate LCD brightness unsuitable for intense daylight but the NX100's optional electronic viewfinder (sold separately) can aid composition inconspicuously.

Macro Capabilities: Precision and Magnification

Macro photography demands close focusing distances, high magnification, and often focus bracketing features.

• The EX-ZR700 includes a macro mode focused as close as 5 cm, paired with sensor-shift image stabilization. This delivers adequate results for casual macro snaps of flowers or insects but lacks precision manual focusing or focus stacking functionality.

• The NX100’s systemwide lens compatibility includes dedicated macro lenses with superior optical performance and more precise focus control (including focus peaking and magnification aids), offering greater creative potential for enthusiasts.

Night and Astro Photography: ISO Handling and Exposure

Low-light and long-exposure scenarios reveal how well a camera handles noise and dynamic range.

• The EX-ZR700, limited by sensor size and noise levels rising sharply above ISO 400, performs adequately only for casual nighttime photography. Its shutter speed minimum of 4 seconds can permit some long-exposure effects but sensor noise dominates.

• The NX100 supports exposures up to 30 seconds and maintains image quality better under high ISO settings due to larger sensor and superior image processor, encouraging experimentation in night or astro photography contexts.

Neither supports custom astro-specific modes or intervalometers natively, limiting advanced workflows.

Video Features: Recording Quality and Usability

Video performance often differentiates otherwise closely matched cameras.

• The Casio EX-ZR700 supports Full HD 1080p at 30 fps, with additional slow-motion modes (up to 1000 fps in reduced resolution). However, absence of microphone or headphone jacks limits audio control and monitoring; stabilization works well during video capture given sensor-shift IS.

• The Samsung NX100 records up to 720p HD at 30 fps only, lacking advanced slow-motion options and audio ports. Video stabilization is not specified and thus likely less effective. While usable for casual clips, it does not meet expectations of modern content creators.

For creators prioritizing video features, the EX-ZR700’s broader video capabilities offer more flexibility despite compact camera limitations.
