Sony 16-25mm f/2.8 FE G

Wide-angle zoom lens with a compact form factor featuring a small focal length range from 16 to 25 mm. The maximum aperture within this range remains constant at f/2.8. The optical design of the model includes 16 elements in 13 groups, including four aspherical lenses and three low-dispersion glass elements. The diaphragm in the Sony 16-25mm f/2.8 FE G consists of 11 blades. In the wide-angle zoom position, the lens focuses sharply from a distance of 17 – 18 mm, and at maximum zoom — from 22 – 23 cm.

Autofocus is handled by a dual linear motor, ensuring rapid autofocus system performance. The lens body features rings for manual focus, zooming, and aperture adjustment. The latter ring can have either a smooth or stepped motion (switched by a separate selector). Other controls include an "AF/MF" focus switch and a programmable button. The model adds 409 g to the weight of a mirrorless camera body.
