Sony's last SLT flagship, a fast APS-C body with translucent mirror technology.
The Sony A77 II launched in 2014 as the final flagship of Sony's A-mount SLT system. Using a translucent mirror that directed light simultaneously to the sensor and AF module, it achieved 12fps burst with full-time phase-detect AF. It represented the pinnacle of Sony's pre-mirrorless APS-C technology.
Key features include the 24.3MP APS-C sensor, 79-point dedicated phase-detect AF module with 15 cross-type points, 12fps continuous burst, OLED EVF, weather-sealed magnesium body, and dual card slots. The translucent mirror enables continuous AF during burst but costs approximately 1/3 stop of light.
The A77 II was praised for exceptional AF performance and burst speed that exceeded Canon and Nikon APS-C competitors. It is criticised for the translucent mirror's light loss and for the A-mount system that Sony effectively abandoned in favour of E-mount mirrorless.
Cheap used as the A-mount system is discontinued. A-mount lenses are orphaned with no development path. Check the translucent mirror for contamination, AF module accuracy, and IBIS operation. Only recommended if you already own A-mount glass or find an excellent deal.
