At 110 x 63 x 36 mm and weighing 283 g, the Sony a5100 represents a compact yet ergonomically conscious mirrorless camera designed for users ready to elevate image quality beyond basic compacts. In contrast, the DSC-W380 is considerably smaller and lighter (91 x 52 x 20 mm at 117 g), crafted primarily for casual shooters prioritizing portability over manual control.

The a5100’s rangefinder-style body offers a more substantial grip surface and physical control layout, enabling extended handheld shooting sessions with improved balance and fatigue mitigation. The lack of a viewfinder on both models places emphasis on LCD usage, but the a5100’s tilting touchscreen (3.0 inches, 922k dots) provides superior framing flexibility and intuitive focusing interfaces, as opposed to the fixed 2.7-inch, 230k dot screen on the W380.

The a5100 presents a mature physical interface with accessible dials and buttons for exposure compensation, autofocus modes, and manual exposure settings - elements absent on the W380. The ultracompact W380’s control ergonomics are minimalistic, based on a fixed lens form factor and limited to basic exposure functions, reflecting its entry-level convenience focus.

For photographers prioritizing ergonomic control and operational agility during extended sessions or complexity in exposure settings, the a5100 is unequivocally preferable, whereas the W380 suits ultra-portable, casual usage scenarios.

Sensor Specifications and Their Impact on Image Quality

One of the most consequential distinctions lies in sensor technology and size. The a5100 features a 24MP APS-C CMOS sensor (23.5 x 15.6 mm, 366.6 mm²) paired with Sony’s Bionz X processor launched in 2014. This sensor size and processing pipeline translate into elevated image quality with noteworthy dynamic range (DxOMark: 12.7 EV) and color depth (23.8 bits), alongside a manageable high ISO ceiling of 25600 (native), maintaining usable noise levels to ISO 1347.

Conversely, the W380 utilizes a diminutive 1/2.3-inch CCD sensor (6.17 x 4.55 mm, 28.07 mm²) with approximately 14MP resolution (4320 x 3240 max). While CCDs of its era impart distinct image character, the small sensor constrains detail resolution, dynamic range, and low-light performance substantially. ISO tops at 3200 but with high noise and limited versatility.

This sensor disparity means that for technically demanding photography - portraits requiring nuanced skin tones, landscapes demanding extensive tonal gradations, or low-light situations like night and astro photography - the a5100 offers decisive advantages. The W380’s sensor suffices primarily for daylight snapshots with acceptable JPEG processing but will struggle to deliver professional-level fidelity or latitude.

Focusing Systems: Precision, Speed, and Tracking

Autofocus technology profoundly shapes practical usability and creative potential. The Sony a5100 is equipped with an advanced hybrid autofocus system combining 179 phase-detection and contrast-detection points. This arrangement yields rapid, accurate focusing under varied lighting conditions and enables real-time continuous AF and tracking modes, including reliable eye-detection - indispensable for portraiture and wildlife photography involving moving subjects.

In stark contrast, the DSC-W380 features a rudimentary contrast-detection AF with only 9 focus points and lacks continuous AF and tracking. Absence of face or eye detection further limits precision for any subject movement. Macro focusing is supported nominally to 5 cm, while the a5100 relies on interchangeable lenses for macro capability but benefits from more advanced focusing aids overall.

Thus, photographers specializing in wildlife, sports, or any motion-sensitive genre - where AF speed and tracking fidelity are paramount - will find the a5100’s system indispensable. The W380 remains suitable for static scenes or casual casual photography where autofocus agility is less important.

Lens Systems and Artistic Flexibility

This modularity unlocks creative freedom and professional-grade image quality so users can adapt to myriad photographic scenarios.

The W380 employs a non-interchangeable fixed lens with a 24-120 mm equivalent focal range (5x optical zoom) and an aperture range of f/2.4 to f/5.9. While this caters well to general point-and-shoot needs covering wide to medium telephoto perspectives, it severely limits creative control over depth of field and optical quality compared to prime or higher-tier zoom lenses.

Professional photographers or serious enthusiasts prioritizing artistic flexibility, selective focus effects, and dedicated focal lengths will inevitably gravitate toward the a5100’s system. Meanwhile, the W380 appeals mostly to users seeking straightforward all-in-one solutions without additional investment in lenses.

Image Stabilization and Shutter Performance

The DSC-W380 incorporates optical image stabilization within its lens system - a critical feature at telephoto extensions and slower shutter speeds to counteract camera shake. The a5100, however, lacks in-body stabilisation (IBIS), relying instead on lens-based stabilization when available.

Shutter speed ranges further underline distinct design ambitions: the a5100 supports shutter speeds from 30 seconds to 1/4000 sec, facilitating long exposures for night or landscape work and fast shutter captures for freezing motion. The W380’s range spans 2 seconds to 1/1600 sec, inherently more restrictive but adequate for casual snapshots.

In practical testing, the a5100’s shutter latency and cycle rates align with its 6 frames-per-second continuous shooting specification, enhanced by responsive AF tracking, making it competent for sports and wildlife burst capture. The W380 manages only 2 fps without AF tracking, inherently limiting its value for action sequences.

Display and User Interface: Interaction Paradigms

Display technology reflects each camera’s user interaction model. The a5100’s 3-inch tilting touchscreen with 922k-dot resolution excels in brightness, color accuracy, and responsiveness. Touch-enabled focus point selection, intuitive menu navigation, and image review increase operational fluidity, especially in live view mode.

The W380 uses a fixed non-touch 2.7-inch, 230k-dot LCD, limiting visibility and touch capability. Menu operation relies on physical buttons only, which may slow user interactions and decrease precision in framing and focusing, particularly for novices or spontaneous shooting.

For photographers favoring speed and reliability in camera setting adjustments, particularly those with workflows incorporating live view framing or video, the a5100’s interface offers distinct, tangible benefits.
