Overview

The Sony Alpha a5100 is a mirrorless camera designed for photographers who want serious image quality without the bulk of a larger body. At its core is a 24.3-megapixel APS-C Exmor CMOS sensor paired with a BIONZ X image processor, delivering sharp, richly detailed photos and smooth Full HD video at up to 60 frames per second. The hybrid autofocus system, featuring 179 phase-detection points, locks onto subjects in as little as 0.07 seconds — making it one of the fastest AF systems in its class and well-suited for capturing fast-moving subjects or fleeting moments.

Despite its compact dimensions, the a5100 includes a 3-inch flip-up touchscreen LCD that tilts 180 degrees for easy selfie framing, along with built-in Wi-Fi and NFC for instant sharing to a smartphone. The pop-up flash provides fill light when needed, and continuous shooting at 6 frames per second with autofocus tracking keeps up with action scenes. The camera's ISO range of 100–25600 ensures usable results in challenging lighting conditions. Sold here as a body only, it accepts any Sony E-mount lens, giving photographers the flexibility to build a system around their specific needs — from wide-angle primes to telephoto zooms.
