The FE 70-200mm f/4 Macro G OSS II, introducing performance upgrades in autofocus, stabilization, magnification, and sharpness while reducing both its length and size. Chief among the 70-200mm f/4 II's enhancements is its faster, video-optimized autofocus system. Featuring 4 XD Linear motors, two for each of the lens' focus groups, the lens now performs 20% faster than its predecessor and supports focus tracking while zooming. The biggest change to the optical design of the lens is the introduction of a floating focusing element, enabling the lens' high-resolution .5x "half-macro" magnification, shrinking the minimum focusing distance to 10.2" at 70mm. This increased resolution is available across the entirety of the zoom range, as is the lens' improved corner-to-corner sharpness. Nano AR Coating II controls flare and ghosting, while the rounded, nine-blade diaphragm supplies the lens with its soft, smooth bokeh. The new autofocus system also works with the Alpha 1's blackout-free 30 fps high-speed continuous shooting, double the rate of the f/4 OSS I. The new autofocus system has near-silent operation while dramatically reducing focus breathing and focus shift. The Linear Response MF system to ensures a consistent, natural-feeling operation. Rounding out the improvements to image quality, the lens' built-in SteadyShot optical image stabilization is designed to work in tandem with the camera body's stabilization system to ensure sharp images while shooting handheld even at the longest focal lengths. The lens is compatible with Sony's optional FE 1.4x and 2.0x teleconverters. These teleconverters allow for life-size, 1:1 macro photography throughout the entire zoom range.

The 70-200mm f/4 II, Sony has kept in mind both the endurance of the lens and its user, reducing both the length and weight of the optic by 15% to 5.8" and 1.7 lb, respectively. A removable and rotating tripod collar for added stability and reducing strain on the camera's lens mount. Three-mode optical image stabilization switch to ensure sharpness in varying shooting conditions. Three focus hold buttons and an AF/MF switch on the lens barrel for intuitive tactile control and rapid access to select settings. A full-time DMF switch for manual focus override during AF-C mode.A fluorine coating for the front-lens element to repel water, oil, and other contaminants and facilitate lens-cleaning.
