Sony FE 200-600mm f/5.6-6.3 G OSS (Used)

High resolution throughout the zoom range

Five ED (Extra-low Dispersion) glass elements and one aspherical element in an optical design offer superb resolution and image quality throughout the zoom range. The aspherical element suppresses spherical aberration and distortion, while the ED glass elements minimize chromatic aberration that can be a problem at super-telephoto focal lengths.
Fast, precise AF keeps up with swift subjects

Sony's DDSSM (Direct Drive SSM) system has the power and precision needed to drive the lens's mechanism for remarkably fast, accurate focusing. High positioning accuracy means that no movement is wasted. Pinpoint autofocus is achieved with blazing speed. The DDSSM system is incredibly quiet, too.
Beautiful, natural G lens bokeh

An 11-blade circular aperture mechanism adds to the beauty of the bokeh produced by this lens, making it possible to use the narrow depth of field available at super-telephoto focal lengths to produce striking images with deep, creamy G lens bokeh.
Excellent control and reliability in the field

An inner zoom mechanism means that the length of the lens does not change while zooming, for stable handheld operation with consistent balance. Customizable focus hold buttons are provided in three locations 90° apart for easy access when shooting in any orientation. A fluorine front element coating plus a dust and moisture-resistant design ensure high reliability in challenging environments.
