Sony Alpha DSLR-A300
The 10.2-megapixel Sony Alpha DSLR-A300 offers Sony’s new Quick AF Live View technology for using the camera’s 230,000-pixel, 2.7-inch tilting LCDs as a viewfinder. Quick AF Live View uses Sony’s Pentamirror Tilt system to direct light to a dedicated live-view sensor instead of flipping the optical viewfinder mirror up and using the main sensor as many live-view systems do. Quick AF Live View enables the camera’s nine-point autofocus system to function during live viewing with no delay, including in tracking AF mode. The camera incorporates Sony’s Bionz processing engine, Super SteadyShot sensor-shift optical image stabilization, an anti-dust system, and a penta-mirror optical viewfinder with 0.75x magnification and 95 percent coverage. It takes Minolta and Sony A-mount lenses.
The A300 offers light-sensitivity settings up to ISO 3200, and a shutter speeds range of 1/4000 to 30 seconds. The camera also offers a bulb mode. Other notable features include eye-start autofocus, which is triggered as soon as the camera is brought near the photographer’s eye, and Sony’s D-Range Optimizer (DRO) for enhancing shadow and highlight detail in high-contrast shots. An advanced DRO mode is available for handling particularly contrasty photos, such as backlit shots. It analyzes multiple areas of the image separately. The A300 offers a 3fps drive mode and can capture an unlimited series of JPEGs or 6 RAW files at a time. The Sony Alpha DSLR-A300 will be available in April 2008. It will be sold in a kit with Sony’s DT 18-70mm f3.5-5.6 lens for about $800. The camera is compatible with Sony’s VG-B30AM vertical battery grip.
