The full-frame compatible FE 90mm f/2.8 Macro G OSS Lens for Sony's E-mount cameras. As a G series lens, it perfectly balances sharpness and bokeh through the use of various specialized elements, this ensures highly detailed images, with smooth out-of-focus areas, and an absolute minimum of aberrations. The lens also boasts a fast f/2.8 aperture for controlling depth of field and working in less-than-ideal light as well as a Nano AR coating that helps eliminate ghosting and flare. On top of this, the focusing ring slides for immediate switching between manual and autofocusing. And, the lens has built-in Optical SteadyShot image stabilization for compensating for camera shake at all focusing distances. The true macro design affords a life-size, 1:1 magnification ratio along with an 11" minimum focusing distance for working with close-up subjects. A focusing distance and magnification scale are also printed on the top of the lens to aid in more technical applications. One aspherical element is incorporated in the lens design to reduce astigmatism, field curvature, coma, and other monochromatic aberrations. A Direct Drive SSM system and internal focus mechanism provide quick, quiet, and precise autofocus performance and also contributes to more natural, intuitive manual focus control. An internal focus design further enhances usability by improving AF speed and ensuring that the overall length of the lens does not change during use. This stabilization system can also be combined with a select camera's sensor-shift type image stabilization for more effective control of camera blur. This lens' focusing ring can be slid forwards and backward to quickly shift from manual to autofocus modes, and vice versa.
