The Sony Alpha a77II DSLR Camera is a versatile and advanced digital camera featuring a 24.3MP APS-C-sized Exmor CMOS sensor and BIONZ X image processor to produce high-resolution still images and full HD movies with marked low-light quality and sensitivity to ISO 25600. Beyond notable imaging traits, the image processor also lends itself to continuous shooting up to 12 fps for up to 26 RAW frames. The processor and sensor combination are also significantly benefitted by the unique Translucent Mirror Technology, which effectively directs light to both the image sensor and focus sensor simultaneously. This enables the expansive 79-point AF system, which includes 15 cross-type points, to work continuously even while recording video and photographing in a continuous shooting mode.
For live view monitoring, image playback, and menu navigation, both a large rear monitor and detailed electronic viewfinder are available. The 3.0" 1,228k-dot LCD screen features a three-way tilting design to facilitate easier use from both high and low angles and also incorporates WhiteMagic technology for easier viewing in bright conditions. The 0.5" 2.359k-dot Tru-Finder OLED EVF offers 100% frame coverage and a refined optical design to provide a natural viewing perspective and magnification. The dust- and moisture-sealed magnesium alloy body also houses a configurable user interface, built around several customizable buttons and control dials, for efficient and intuitive access to frequently used camera settings. Additionally, a Multi-Interface shoe is available for attaching external flashes, lights, or microphones.
Built-in Wi-Fi connectivity, with support for NFC-enabled devices, is also integrated into the a77II to support remote camera control and image sharing to linked mobile devices.
Included with the camera body is the DT 16-50mm f/2.8 SSM lens; a wide-angle to short telephoto providing a 35mm-equivalent focal length range of 24-75mm. The constant f/2.8 maximum aperture maintains consistent performance throughout the zoom range while an SSM autofocus drive produces quick and quiet focus performance. Two aspherical elements and three extra-low dispersion elements are incorporated within the lens construction, which help to reduce chromatic aberrations and produce imagery with a high degree of sharpness and clarity. Additionally, the lens is designed with the same weather-resistant qualities as the a77II to permit its use in inclement conditions.
