Overview

The Sony SLT Alpha A57 is a digital single-lens translucent (DSLT) camera released in 2012, featuring a 16.1-megapixel APS-C CMOS sensor designed for high-resolution imaging. Unlike traditional DSLRs, it utilizes a fixed translucent mirror technology allowing for faster continuous shooting at up to 12 frames per second while maintaining full-time phase-detection autofocus.

This model supports Full HD 1080p video recording with enhanced SteadyShot INSIDE image stabilization, providing smooth video capture and sharp stills even in low-light conditions. The BIONZ image processor ensures rapid data processing and high ISO sensitivity range, enabling better noise control.

The camera is equipped with a high-resolution electronic viewfinder (EVF) for real-time exposure preview and a variable-angle 3.0-inch LCD screen for flexible shooting angles. Connectivity options include HDMI output and support for various interchangeable Sony A-mount lenses. The robust build and comprehensive feature set make it a versatile tool for both photography enthusiasts and semi-professional users.
