This stark difference underlines a fundamental divergence in user philosophy: Samsung targets beginner to enthusiast photographers interested in gradual skill mastery, while Sony caters to casual users prioritizing ultra-lightweight cameras.

Looking at the top view reveals the NX100’s advantage of manual shutter speed and aperture priority controls, which are absent in the W550. The W550 lacks physical exposure control dials - having a simpler shutter button and mode dial - reinforcing Sony’s minimalist operational design.

Sensor Technology: The Foundation of Image Quality

Sensor performance critically defines image quality, low-light capabilities, dynamic range, and depth rendering. Here we see a striking contrast.

The NX100’s APS-C CMOS sensor, measuring 23.4x15.6 mm, affords substantially larger light-gathering area compared to the W550’s minuscule 1/2.3” CCD sensor. This advantage translates into superior color depth and dynamic range - supported by a DxOMark overall score of 62 for the NX100 (Sony W550 remains untested by DxOMark due to its sensor class).

Technically, the DRIMe image processor leveraged by Samsung facilitates lower noise levels and smoother tonal gradations, crucial for demanding genres like landscape and portrait. In contrast, the W550’s compact sensor size and CCD architecture limit its dynamic capabilities, increasing noise at higher ISOs and reducing color accuracy in challenging conditions, though adequate for casual snapshots and daylight use.

Image Quality and Real-World Performance

Portrait Photography: Color Accuracy, Bokeh, and Eye Detection

Portraiture demands natural skin tone rendition, shallow depth of field for subject isolation, and ideally, reliable face/eye detection autofocus. The NX100 excels in these aspects thanks to its sensor and lens flexibility.

• Samsung NX100: The combination of an APS-C sensor and the Samsung NX mount with over 30 native lenses, including fast primes, enables creamy bokeh and fine detail reproduction. Face and eye detection autofocus are built-in, enhancing sharpness on eyes and preserving skin tones faithfully under varied lighting. Image stabilization embedded in the system adds resilience to handheld shooting, preserving detail clarity.

• Sony W550: Limited by a small fixed lens (equivalent focal range 26-104 mm, max aperture f/2.7-5.7), shallow depth of field effects are constrained. No AF face or eye detection results in less precision, risking softness especially in lower light. Skin tone rendition is serviceable in daylight but tends to lose nuance under artificial lighting.

Landscape Photography: Dynamic Range and Resolution

Landscape photography benefits from high megapixel counts, expansive dynamic range to capture shadows and highlights, and robust build quality.

• Samsung NX100: Its 15 MP APS-C sensor and a dynamic range rating of 10.7 EV on DxOMark enable capturing scenes with rich tonal gradations. Coupled with weather-resistant lenses in its system (though the body lacks sealing), the NX100 offers high-resolution output with fine detail retention, especially when tripod-mounted. The sensor's lower noise floor allows shooting at ISO limits preserving highlight details and shadow information, crucial in sunrise/sunset conditions.

• Sony W550: The small CCD sensor’s dynamic range is limited, struggling to hold highlight and shadow detail simultaneously - especially in high-contrast scenes. The 14 MP resolution is similar on paper but less effective due to sensor size constraints. Its construction does not include environmental sealing, limiting outdoor reliability. The fixed zoom lens is decent but lacks the sharpness of interchangeable good-quality landscape lenses.

Wildlife Photography: Autofocus Speed, Burst Rate, Telephoto Reach

Wildlife demands fast, accurate autofocus, high continuous shooting rates, and long focal lengths.

• Samsung NX100: Features 15 contrast-detection AF points with face detection, but no phase-detection or animal eye AF, restricting tracking of fast-moving subjects. The burst rate maxes out at 3 fps - adequate for slow to moderate motion but insufficient for action-packed wildlife. However, mount compatibility with telephoto lenses (thanks to the native NX mount) allows flexible reach.

• Sony W550: Autofocus system is contrast-detection only with 9 points and notably slower to lock, with no tracking ability. Burst shot speed is a sluggish 1 fps, making it unsuitable for wildlife action. The zoom lens covers 26-104 mm equivalent - a mild telephoto range but inadequate for most wildlife shooting beyond distance portraits.

Sports and Action Photography: Tracking, Low Light and Frame Rates

Sports photography is demanding due to fast subject movement and variable lighting.

• NX100’s 3 fps continuous shooting rate at full resolution and contrast-detect AF restrict its ability to capture decisive action, whereas professional sports shooters typically require 8-12 fps or more with phase-detection AF. The lack of phase detection in the NX100 further limits tracking accuracy. Nonetheless, its APS-C sensor and moderate high ISO ceiling (max 6400) afford relatively better low-light capture compared to the W550.

• The W550, confined to a single frame per second in burst and lacking any manual exposure modes, is largely unsuitable for serious sports shooting. Its maximum shutter speed of 1/1600 sec and aperture range constrains ability to "freeze" fast motion or shoot in dim indoor arenas.

Street Photography and Portability: Discretion, Low-Light Usability, and Convenience

For candid street photography, portability and low-light performance with minimal fuss are key.

• Sony W550 shines as an ultracompact companion, its small size and light weight favoring inconspicuous shooting and rapid deployment. However, image quality in low light is hampered by sensor limitations and absence of advanced AF modes, which impairs capturing fleeting moments in dimmer conditions.

• Conversely, the NX100 is larger but manageable and, with superior sensor sensitivity and face detection autofocus, can perform notably better during evening street captures. Its manual controls and ability to swap lenses offer greater creative potential in varied street scenes.

Macro Photography: Magnification, Focusing Precision, Stabilization

Macro enthusiasts require fine focusing precision, often aided by toggles like focus peaking or focus bracketing, alongside effective stabilization to manage narrow depth-of-field at close distances.

• The NX100 lacks dedicated focus bracketing or stacking features but benefits from built-in stabilization (although details on type are unspecified), a sizeable sensor that gathers more light for sharp close-ups, and flexible lens options including dedicated macro optics from the NX lens lineup. Manual focus support enables precise adjustments.

• The W550 has a minimum macro focus distance of 5 cm, which is favorable for casual close-up shots; however, without manual focus or stabilization support and constrained sensor size, macro results tend to lack fine detail and sharpness under challenging focus conditions.

Night and Astrophotography: High ISO Performance and Exposure Flexibility

Shooting at night or astrophotography demands cameras with low noise at high ISO and manual exposure capabilities.

• The Samsung NX100 supports native ISO up to 6400, and with no anti-aliasing filter, can preserve star sharpness. It offers manual shutter and aperture control, essential for bulb exposure or long exposures. Image stabilization reduces blur from handheld exposures. These attributes make it a competent choice for beginners exploring astrophotography.

• The Sony W550 tops out at ISO 3200 with no manual shutter/aperture control, limiting exposure flexibility. Longer shutter speeds beyond 2 seconds are unsupported, restricting usage for astrophotography or extended night scenes.

Video Capabilities: Recording Quality, Stabilization, and Audio Inputs

Video continues to gain importance for hybrid photographers/videographers.

• The NX100 records HD 720p video at 30 fps encoded in H.264 format, capturing decent quality for its time. However, it lacks external microphone or headphone ports, limiting audio flexibility. No 4K or slow-motion options exist. Optical/image stabilization helps smooth footage to an extent.

• The W550 also outputs 720p video at 30 fps, but in MPEG-4 format, with no audio input or stabilization during video. It’s primarily a grab-and-go video option for casual use.

Build Quality, Weather Resistance and Durability

Both cameras lack extensive weather sealing or ruggedness features, trading robustness for compactness and cost-efficiency.

• The NX100 sports a well-constructed body that feels durable under normal use but lacks official dust, water, or freeze-proofing. Lens options may vary in durability.

• The W550’s plastic ultracompact shell is vulnerable to impacts and elements, designed for light everyday carry rather than challenging environments.

Ergonomics, User Interface and Viewing Experience

Understanding user interface and usability from experience shapes daily photography enjoyment.

• The NX100 features a fixed 3” VGA AMOLED screen with 614 k dots - bright and vibrant for outdoor previewing. Despite lacking a built-in viewfinder, an optional electronic viewfinder was available. Manual controls on the body, including exposure dials and customizable buttons, support workflow efficiency.

• The W550’s 3” Clear Photo LCD is much lower resolution (230 k dots), offering a less crisp preview. Absence of any viewfinder and minimal control buttons highlight its simplicity but limit usability under challenging light or for precision shooting.
