1. The A99's 2.36-million-dot OLED EVF eliminates the need for a bulky glass pentaprism. 2. Dual card slots let you save files on SD/SDHC/SDXC cards or Sony Memory Stick PRO/PRO-HG Duo media. 3. The big translucent mirror doesn't move, so there are no mirror vibrations, and you get full-time phase-detection AF, even for movies.

Sony SLT-A99

Estimated Street Price: $2,800 (body only)

INTRODUCED
9/2012
In 2010, Sony introduced the first cameras with its Translucent Mirror Technology (TMT)—the entry-level SLT-A55 and A33. A fixed translucent mirror transmits most of the light to the image sensor while simultaneously directing a portion of it up to the camera's phase-detection AF sensor. While conventional DSLRs must alternate focusing and exposing, since the SLR mirror must be down for the former and up for the latter, TMT allows the camera to continuously autofocus and expose at the same time. This speeds up operation, minimizes moving parts and vibration, and provides continuous quick phase-detection autofocusing for still and video shooting.

Previous TMT cameras used APS-C sensors. Now, Sony has introduced the first full-frame TMT camera, the flagship SLT-A99. It features a new 24.3-megapixel, full-frame Sony Exmor HD CMOS sensor and 14-bit capture (another first for the SLT line) and a new twist on the TMT AF system—besides the standard 19-point TMT AF system, there are also 102 phase-detection AF points on the image sensor itself. This provides more accurate tracking of fast-moving subjects against complex backgrounds. An in-body AF Range Control further helps AF speed and accuracy.

An excellent 2.36-million-dot OLED electronic viewfinder provides eye-level viewing for stills and video, while the 3-inch LCD tilts and rotates for easy odd-angle shooting.
The A99 is the first full-frame DSLR to do full HD 1080 AVCHD video at 60p (a capability recently introduced in some Sony APS-C cameras) as well as 24p; it also does 1080, 720 and 480 video at 30p in MP4 format. You get continuous phase-detection AF for video, convenient eye-level viewing when desired and stereo sound via a built-in mic or an optional external mic. Full-res, 24.3-megapixel still images can be shot at up to 6 fps (cropped APS-C-format images at up to 10 fps).

STANDOUT FEATURE: The first full-frame Translucent Mirror Technology camera.
