Sony A380 vs Sony RX10 IV: A Deep Dive into Two Very Different Cameras

When choosing your next camera, it’s crucial to find a model that fits your unique photography style, experience level, and budget. Today, we’re comparing two Sony cameras from very different generations and categories: the Sony Alpha DSLR-A380 (an entry-level DSLR launched in 2009) and the Sony Cyber-shot DSC-RX10 IV (a 2017 large-sensor superzoom bridge camera). Despite their shared brand DNA, these models cater to distinctly different photographic ambitions and user needs.

In this comprehensive comparison, we’ll explore everything - from sensor and image quality to autofocus, build, and versatility - across popular photography disciplines and use cases. By working through this, you’ll gain actionable insights for whether an affordable DSLR or a high-end superzoom bridge camera is your better next tool.

Getting to Know the Cameras Physically and Ergonomically

Before diving into tech specs, the physicality of a camera affects the shooting experience for many photographers, especially during long sessions.

Sensor Insights from Experience

  • Sony A380’s APS-C Sensor: Larger sensor area, typical of DSLRs, results in better light-gathering ability, improved dynamic range, and generally lower noise at equivalent ISOs. CCD technology at the time provided good color depth (22.6 bits measured by DxOMark) and dynamic range (~11.8 EV), rivaling many competitors in 2009.

  • Sony RX10 IV’s 1-inch BSI-CMOS Sensor: Smaller sensor means less light per pixel but Sony compensates with latest BSI-CMOS tech for faster readout and better high-ISO performance. It offers 20MP resolution, allowing for more cropping and detailed enlargements, though with somewhat more noise in extreme low-light. The max ISO of 12800 gives it excellent flexibility for dimmer conditions.

In real-world shooting, the A380 excels in landscapes and studio portraits where image quality and color fidelity outweigh superzoom needs. The RX10 IV’s sensor is outstanding for a bridge camera, achieving near-DSLR quality with much more versatility in focal length.

Autofocus Performance: Speed, Accuracy & Tracking

Autofocus (AF) systems make or break a camera’s ability to capture sharp moments - especially in wildlife, sports, or street photography.

Feature Sony A380 Sony RX10 IV
AF Points 9 (phase-detection) 315 (hybrid phase + contrast AF)
AF Modes Single, Continuous, Live View Single, Continuous, Tracking, Face/Eye Detection, Animal Eye AF
Face Detection Yes Yes
Eye AF No Yes (human and animal)
Tracking AF No Yes
AF Performance Moderate (entry-level) Exceptional (professional-grade)

The RX10 IV features Sony’s advanced hybrid autofocus system, blending rapid phase-detection all over the frame with fine-tuned contrast detection. Its 315 focus points cover wide focal ranges and lighting conditions, and Eye AF works on humans and animals, a real game-changer for portrait and wildlife shooters. Additionally, continuous 24 fps burst shooting with autofocus tracking means you won’t miss fast-moving action.

By contrast, the A380’s 9-point AF system offers solid baseline focusing but lacks tracking and eye-detection. It can hunt in live view and slower continuous modes, making it less ideal for dynamic subjects but adequate for portraits and landscapes.
