The SLT-A99V is Sony’s first full-frame TMT (Translucent Mirror Technology) camera. Rather than employing a moving mirror as conventional DSLRs do (and having to flip it up and down so light can get to the viewfinder for composing, then to the sensor for exposure), the SLT cameras use a fixed, semitranslucent mirror that passes the majority of the light to the image sensor and reflects some light to the phase-detection AF sensor. The advantages of this system are several: full-time continuous phase-detection AF during live-view and video shooting, eye-level viewing for live-view and video, and no mirror vibration. The fixed mirror and electronic viewfinder also are less bulky and costly than the complex moving-mirror/focusing-screen/pentaprism system of the conventional DSLR. The unique-to-Sony TMT technology isn’t the SLT-A99V’s only asset. Here are more of the features that make this camera ideal for professional photographers.
24-Megapixel APS-C Sensor
The SLT-A99V features a new full-frame 24.3-megapixel Sony Exmor HD CMOS sensor that delivers JPEG or 14-bit RAW images measuring 6000×4000 pixels at ISO settings from 100-12,800 (expandable to 50-25,600).
The SLT-A99V replaces the conventional DSLR’s pentaprism eye-level finder with a high-resolution (2359K-dot) OLED electronic viewfinder—the same highly regarded EVF used in the popular SLT-A77. The EVF also allows you to preview exposure and effects, provides extensive information displays when you want them and offers a greater range of dioptric correction than typical DSLRs.
New AF System
In addition to the standard high-end Sony 19-point (11 cross-types) phase-detection AF system, the SLT-A99V adds 102 phase-detection AF points on the image sensor. The new AF-D (Depth-Map) AF system uses both to provide better continuous tracking of moving subjects. A new AF Range Control lets you decide the distances through which the lens will search for focus to avoid unnecessary focus-hunting and speed up focus acquisition.
6 fps (And More)
The SLT-A99V can shoot full-frame, full-resolution images at 6 fps with continuous AF (7 fps in 10-megapixel APS-C mode) and can shoot 8-10 fps in Tele Zoom Continuous Advance Priority mode. It also can do 8 fps at any aperture, with exposure set for each frame.
Professional HD Video Capabilities
The SLT-A99V is the first full-frame DSLR to offer 1080 full HD AVCHD video at 60p, as well as 60i and 24p; it can do 1440×1080, 1280×720 and 640×480 MP4 video at 30p—all with full-time phase-detection AF and eye-level viewing. You also can output uncompressed video files to external devices via HDMI. Sound is stereo via built-in microphones or an optional external mic; there’s also a headphone jack.
Rugged Pro Body
Despite being the lightest full-frame DSLR, the SLT-A99V features a rugged pro body with magnesium-alloy construction and sealing against dust and moisture. The shutter has been tested to 200,000 cycles. The SLT-A99V provides in-camera AF fine-tuning and automatic correction for vignetting, chromatic aberration and distortion.
Despite its big full-frame sensor, the SLT-A99V incorporates Sony’s SteadyShot INSIDE sensor-shift image stabilization, which works with all lenses. Like all Sony DSLRs, the SLT-A99V can use all Sony A-mount lenses (DT lenses designed for APS-C sensors will vignette) and legacy Konica Minolta Maxxum lenses. Sony A-mount lenses currently range from a 16mm ƒ/2.8 full-frame fisheye and 20mm ƒ/2.8 superwide-angle to a 500mm ƒ/4 supertelephoto.
Other Key Features
The bright, high-res, 1229K-dot, 3.0-inch LCD monitor tilts in almost any direction for more compositional possibilities. The SLT-A99V has two media slots: one that accepts SD, SDHC and SDXC cards, and another that accepts those plus Sony Memory Stick PRO Duo and PRO-HG Duo media. You can connect a studio flash system via the built-in PC connector.The SLT-A99V has a built-in GPS unit that automatically geotags your images with latitude, longitude and altitude as you shoot. You then can use the data to see where a given image was shot, organize and search for images, and place images on maps.
