- 24.3 MP 35 mm Full Frame Sensor: A whole new world of high-quality images are realized through the 24.3 MP effective 35mm full-frame sensor, a normal sensor range of ISO 100 - 32000, and a sophisticated balance of high resolving power, gradation and low noise.
- Uncompressed HDMI Output: Easily record Full 1080 HD uncompressed clean-screen video files to external recording devices via an HDMI connection in 24p, 60p and 60i frame-rates.
- Multi-frame NR: Experience incredible low-light shooting without a flash. The camera captures six images in a fraction of a second. Combining the data from all six, it creates a single image with a reduction in noise equivalent to two additional steps of ISO sensitivity. Sensitivity selectable up to ISO 25600.
- World's first Dual AF system: The 19-point AF system with 11 cross sensors is complemented by a multi-point focal plane phase-detection AF sensor with 102 AF points that overlays the image sensor.
- New AF-D Mode: This highly advanced Continuous AF mode uses 19 AF points with reliable depth-direction focusing performance to steadfastly capture subjects and is strongly assisted by the 102-point multi-point focal-plane phase-detection AF sensor. It continues to focus on the subject whether it's moving in depth or plane direction.
- AF Range Control: Users can set the range of distance from the camera in which subjects can be focused on the AF system. By limiting the AF range, users can prevent unwanted focusing on foreground and background objects. This intelligent function enables reliable performance when photographing sports through wire mesh fences, for example.

The Tele Zoom High Speed shooting mode shoots up to 8 fps at 10 MP.
- Three-way tiltable LCD: The SLT-A99V is the first in the Alpha series to feature WhiteMagic technology, which nearly doubles the visibility of the 921k-dot Xtra Fine LCD monitor in sunny outdoor conditions. The three-way tilt-able mechanism, highly acclaimed on on the A77, is further enhanced for even greater operational ease.
- XGA OLED Viewfinder: There's never been anything quite like the Tru-Finder OLED electronic viewfinder. For size, speed and brightness even after sunset, this is a gem. It begins with 2359K dots for amazing resolution and high contrast ratio for incredible depth. OLED reduces motion blur to a bare minimum.

Controls also feature a durable structure that withstands the touch usage of advanced amateurs.
- Approximate 200,000 shutter release durability: The newly developed, highly durable and reliable shutter unit has been proven to endure approximately 200,000 shutter releases. This durability ensures long-lasting shooting performance that takes into consideration the large number of photos shot by advanced amateurs.
- Meticulous, intuitive design: While inheriting the popular design concept of the A77, the SLT-A99V enables comfortable photo shooting through meticulously designed features including improved grip thickness that enhances grasping ease, switch and button shapes that are differentiated for easier operation.
