BSI 2 Technology Explained: Why It Matters in Autofocus Cameras

BSI 2 (Backside Illumination) technology enhances image sensors by improving light capture efficiency, especially in low-light conditions. It minimizes pixel interference, enabling sharper, faster, and more accurate autofocus performance in cameras. By relocating circuitry to the back of the sensor, BSI 2 maximizes the sensor's active area, boosting sensitivity and image quality. This advancement is particularly critical for smartphones and compact cameras, where space is limited but high performance is demanded. BSI 2 technology ensures better low-light imaging, improved dynamic range, and enhanced focus precision, making it essential for professional and casual photographers alike.
