Bringing the speed Sony mirrorless shooters have been waiting for, the Alpha a9 Mirrorless Digital Camera takes impressive multimedia capabilities and ups the processing capabilities for ultra-fast continuous shooting. Making use of a 24.2MP full-frame Exmor RS stacked CMOS sensor and BIONZ X image processor, the a9 is capable of shooting at up to 20 fps, recording UHD 4K video internally, and shooting with an expanded sensitivity range to ISO 204,800. Balancing the quickness of the processor is a well-matched 693-point phase-detection autofocus system that covers 93% of the image area for accurate and quick subject tracking in a variety of lighting conditions. Additionally, complementing both the imaging and focusing assets, the a9 also sports 5-axis SteadyShot INSIDE image stabilization to minimize the appearance of camera shake when shooting handheld.
Matching its professional imaging capabilities is a well-rounded physical construction that is fully weather-sealed for use in trying environmental conditions. For clear, uncompromised viewing, a quad-VGA OLED Tru-Finder is featured with an impressive 3.686m-dot resolution and 120 fps refresh rate for clear, bright, and smooth eye-level viewing. Alternatively, a 3.0" 1.44m-dot tilting touchscreen LCD is also available to benefit working from high and low angles. Dual SD memory card slots, a customizable menu system, and a variety of physical control dials further round out the camera's intuitive design, and built-in Wi-Fi and Bluetooth enables wireless image sharing and remote camera control from linked mobile devices.
A fast and flexible wide-angle zoom, the FE 16-35mm f/2.8 GM Lens from Sony is a wide-angle zoom designed for full-frame E-mount mirrorless cameras. Distinguished by its constant f/2.8 maximum aperture, this lens offers consistent performance throughout the zoom range and benefits working in low-light conditions. The optical design incorporates two extra-low dispersion elements to reduce chromatic aberrations along with two XA elements and three aspherical elements, which significantly controls spherical aberrations for a high degree of image sharpness and clarity. Additionally, a Nano AR coating has been applied to limit ghosting and lens flare for increased contrast and color fidelity when working in strong lighting conditions.
Complementing the optical assets, this lens is also notable for its inclusion of an 11-blade circular diaphragm to produce smooth, soft-edged bokeh with selective focus imagery. For controlling focus, two Direct Drive SSM AF groups are employed that are quick and quiet, and also lend more responsive control for manual focus operation. The lens also sports a dust- and moisture-sealed design to support shooting in inclement conditions and a dedicated focus hold button and AF/MF switch.
