Sony SEL FE 90mm F2.8 Macro G OSS The Sony SEL FE 90mm F2.8 Macro G OSS lens with built-in image stabilization provides excellent G Lens image quality. It ensures backgrounds with pleasing bokeh, so your subject will catch the eye. The individual calibration of each lens allows for optimal compensation of spherical aberration: as a result, the corners are soft, without leaving a trace of the ugly "nisen bokeh." Macro lenses are often used for a wide range of focusing distances, so a floating focus mechanism has been implemented in this 90mm lens to eliminate aberration due to close-up focusing. The floating system reduces the size of the lens while maintaining excellent brightness throughout the frame from infinity to the minimum focusing distance.
