Optics and coatings

The optical design uses three fluorite elements and a large XA (extreme aspherical) element. The 11-blade circular aperture gives a maximum aperture of f/4 and a minimum of f/22. Sony's Nano AR Coating and flocking on critical interior surfaces reduce flare and ghosting, and the front element has a fluorine coating that repels water, oil and other contaminants.

Focusing and stabilisation

Two XD (extreme dynamic) linear motors drive the autofocus. Optical SteadyShot includes MODE 2 for panned shots and MODE 3 for sports or wildlife action. The FULL TIME DMF switch engages manual focus when the focus ring is turned, even in AF-C. Minimum focus distance is 4.5 m, with a maximum magnification of 0.14x.

The lens weighs 3,040 g including the tripod mount, and measures 163.6 x 449 mm. It has a dust and moisture resistant design, and magnesium alloy is used for the barrel exterior, tripod mount and critical interior parts. The SEL14TC (1.4x) and SEL20TC (2.0x) teleconverters are compatible.
