Superb corner-to-corner resolution and contrast throughout the zoom range are achieved by combining AA (advanced aspherical) and aspherical lens elements. Three ED (Extra-low Dispersion) elements and one Super ED element suppress chromatic aberration and color bleeding for revealing sharpness.

This is the world’s first zoom lens in its class to offer half-macro capability throughout the zoom range. Minimum focusing distance is 0.26m at the wide end and 0.42m at the telephoto end of the zoom range, with a maximum magnification of 0.5x throughout.

Four of Sony’s original high-thrust XD linear motors work in conjunction with precision floating focus groups to achieve accurate focus drive. Thrust efficiency has been dramatically improved, resulting in up to approximately a 20% increase in autofocus speed. Focus tracking continues uninterrupted.

Linear Response MF ensures that manual focus responds directly and linearly to subtle control. The breathing compensation function provided in compatible α series bodies is fully supported. Built-in optical image stabilization can work in conjunction with the in-body stabilization.

The FE 70–200 mm F4 Macro G OSS II is fully compatible with Sony’s 1.4x and 2.0x teleconverters. The 2.0x teleconverter makes it possible to shoot life-size 1:1 macro at all focal lengths. Attached with the 1.4x teleconverter, it can shoot max. 0.7x macro at all focal lengths.

This lens offers a rare blend of performance and mobility. It is 3.25 in. in diameter by 5.88 in. in length at the wide end of the zoom range and weighs 28.1 oz. An extending lens design was chosen to maximize portability, and a zoom lock switch is provided to prevent unwanted lens extension.
