Sony's last SLT flagship, a fast APS-C body with translucent mirror technology.
The Sony Alpha SLT-A77 II was announced in May 2014 as the successor to the A77, using an SLT (Single-Lens Translucent) fixed pellicle mirror design that passes light simultaneously to both the sensor and the dedicated phase-detection AF module. This architecture enables continuous phase-detect AF at full burst rate — unlike DSLR systems that must flip the mirror up between frames, the A77 II maintains AF tracking throughout a 12fps burst. It was the last major A-mount SLT camera before Sony focused development on the E-mount system.
The 24MP APS-C CMOS sensor pairs with the Bionz X processor. The 79-point AF system — using both sensor-based and dedicated AF module points — provides comprehensive coverage for continuous tracking at the 12fps burst rate. 4K video is not supported; 1080p records at up to 60fps. Weather sealing is built in with a double-layer structure around controls, dials, and ports. Battery life approximately 470 shots using the NP-FM500H, body weight approximately 726g with battery and card, dual SD/Memory Stick Duo card slots.
The A77 II's SLT architecture provides AF tracking at 12fps that traditional DSLR mirror-flip designs could not achieve at equivalent burst rates without sacrificing live AF. For sports, wildlife, and event photography where continuous phase-detect tracking at 12fps is the requirement, the SLT design delivers this combination. The A-mount system has a wide range of Sony and third-party native lenses, with Phase-Detection on-chip AF for accurate tracking.
On the used market the A77 II is affordable as the final A-mount SLT flagship. Condition checks: pellicle mirror surface for dust (visible as spots in images that appear at closed apertures), weather sealing, and NP-FM500H battery health. The A-mount ecosystem requires A-mount native lenses — E-mount lenses require an LA-EA adapter for use on A-mount bodies. Sony has discontinued new A-mount lens development. Compatible with all Sony A-mount lenses; E-mount lenses via LA-EA adapter.
