If you prefer to use the external LCD monitor, it's a good one, a 3.0-inch 1,229,000-dot unit with a 16:9 (HD) aspect ratio and the ability to tilt 140 degrees up, 180 degrees down, 180 degrees clockwise and 90 degrees counterclockwise—great for video, macro and odd-angle shooting. Like the EVF, the LCD can display lots of shooting information when you want it, including a digital level gauge to keep those horizons truly horizontal.
New 24.3-Megapixel CMOS Sensor
While the resolution is about the same as the DSLR-A900's, the SLT-A99's 24.3-megapixel Sony Exmor HD CMOS sensor is several generations newer. (Sony's storied 16-megapixel APS-C sensor surpassed the original A900's full-frame one in DxOMark.com's RAW sensor ratings, and that was two years ago; imagine what two more years of development has done for a larger full-frame sensor.)
Sony's Sweep Panorama mode was introduced in point-and-shoot compact digicams, but this simple and useful feature has now made it into the flagship SLT model. Just sweep the camera across the scene, and it will take a bunch of frames and stitch them into a wide panoramic image in-camera.
Despite the size of 24.3-megapixel image files, the A99 can shoot full-res images at 6 fps (7 fps in APS-C crop mode) with phase-detection AF. This is plenty for lots of outdoor action, including birds in flight.
Super SteadyShot Stabilizatio
Like all Sony DSLRs, the SLT-A99 features Super SteadyShot sensor-shift image stabilization, which works with any lens you mount on the camera. All your lenses are stabilized when you use this camera.
In manual-focus mode, you can activate focus peaking, which clearly indicates where focus is in your scene or subject, especially handy for macro work and landscapes.
Auto HDR automatically combines three quick bracketed exposures in-camera to create a final image with more detail from shadows through highlights. You can choose the increments (1-6 EV) or let the camera do it. DRO (Dynamic Range Optimizer) extends shadow and highlight detail in a single shot, and is also auto or adjustable.
Like all Sony DSLR and SLT cameras, the A99 can use all Sony A-mount lenses, as well as legacy Konica Minolta Maxxum lenses. Currently, the Sony lenses range from a 16mm full-frame fisheye and a 16-35mm superwide zoom to a 500mm supertelephoto, plus 1.4X and 2X teleconverters. (DT lenses designed for APS-C sensors can be used, but will vignette.)
