Verdict

The Sony SLT-A77 is a semi-professional APS-C camera featuring a 24.3-megapixel CMOS sensor and Sony’s proprietary Translucent Mirror Technology, which enables high-speed performance including a blistering 12 fps burst rate with full-time phase-detection autofocus. Key characteristics include a high-resolution 2.4M-dot XGA OLED electronic viewfinder, a unique three-way tilting 3-inch LCD, and a durable, weather-sealed magnesium alloy body. Its primary pros are its exceptional speed, built-in GPS, in-body image stabilization, and high-quality 1080p60 HD video. However, its main cons involve relatively poor high-ISO noise performance above 1600, a shallow buffer that fills quickly during bursts, and subpar battery life compared to traditional DSLR competitors.
