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.

Handling | DSLR grip with physical dials | Larger, heavier bridge grip |
The A380 is much lighter and smaller, typical of entry-level DSLRs, making it popular among hobbyists and those transitioning from compact cameras. The RX10 IV doubles the weight and depth due to its integrated superzoom lens and weather-sealed body. Its electronic viewfinder offers a brighter, end-to-end preview with 100% frame coverage - an advantage when precise framing counts.
Ergonomically, the RX10 IV feels more robust and mature. Its larger grip and control layout (visible below) support better handling for prolonged shooting and heavier bursts common in action and wildlife photography.
The A380’s controls are fewer in number - good for simplifying photography learning but limiting customization. In contrast, the RX10 IV provides more dedicated buttons and customizable dials, streamlining quicker adjustments in fast-paced environments.
Sensor Technology, Resolution & Image Quality
The heart of any camera is its sensor. Despite being an older DSLR, the Sony A380 features a larger APS-C sensor, while the RX10 IV uses a smaller 1-inch sensor designed for its integrated zoom lens.

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 |
