Get up close and personal with the 1:1 magnification ratio of the full-frame compatible FE 90mm f/2.8 Macro G OSS Lens for Sony's E-Mount mirrorless cameras. Optimized for macro shooting, this medium telephoto lens utilizes an aspherical element along with extra-low dispersion and super extra-low dispersion glass in order to create sharp imagery with minimal aberration. Also, it has a Nano AR Coating that suppresses reflections and allows for efficient light transmission for clear photographs. Its maximum aperture of f/2.8 is effective when shooting in low light and allows for shallow depth-of-field focus. An internal focus system in which only the middle optical groups move when focusing provides fast autofocus action and a short minimum focus distance of 11". Also, the lens does not extend when focusing and the front end does not rotate. The Direct Drive Super Sonic Wave AF motor employs piezoelectric elements oscillating at ultrasonic frequencies to drive the focus lens with accuracy and near-silence. The focus ring slides back and forth to select manual or auto focus and with a focus hold button and focus limiter switch, the lens offers precise control of where you place focus. An optical image stabilization system uses gyro sensors to detect camera movement and quiet linear motors to shift the stabilization lens for blur control that is very helpful when shooting macro and/or in low light. Nine circular aperture blades create a unique diaphragm design that is almost perfectly circular throughout its aperture range and thus helps to create pleasing out-of-focus highlights. Finally, a handsome and sturdy build with a dust and moisture resistant design contributes to the overall quality and durability of this fine optic.
