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, standard zoom favored for its versatility, the Sony FE 24-70mm f/2.8 GM is a wide-angle to short telephoto lens designed for E-mount mirrorless cameras. Featuring a constant f/2.8 maximum aperture, this lens maintains consistent performance throughout the zoom range and benefits working in low-light conditions and with selective focus techniques. Complementing the apt light-gathering capabilities is an equally impressive optical design, which incorporates three aspherical elements and two extra-low dispersion elements. One of the aspherical elements features an XA (extreme aspherical) designation, ensuring its refined surface precision and notable ability to minimize spherical aberrations throughout the zoom range. Additionally, a Nano AR Coating has been applied to individual elements to significantly minimize lens flare and ghosting for increased contrast and color neutrality. Pairing a sophisticated optical design and versatile speed, this standard zoom is well-suited for use in a wide array of environments and lighting conditions.
Beyond the attributes of the lens system itself, this 24-70mm is also characterized by a Direct Drive SSM (Super Sonic wave Motor) system that provides fast, quiet AF performance as well as responsive manual focus handling. The lens is also dust- and moisture-sealed, to permit working in inclement weather conditions, and nuanced details, such as a focus hold button and rubberized control dials, further the intuitiveness in handling.
