The Sony FE 100mm f/2.8 STF GM OSS lens is a sophisticated short-telephoto prime lens that excels in delivering both exquisite bokeh and fine sharpness. Its standout feature, Smooth Trans Focus (STF) technology, uses an apodization (APD) element to produce incredibly smooth, circular bokeh with rounded out-of-focus highlights. This technology, combined with the 11-blade rounded diaphragm, ensures a beautiful, natural blur in both the foreground and background, ideal for portraiture and other selective-focus applications.

The optical design of the lens also prioritizes clarity and color accuracy, featuring a G Master-level construction that includes one extra-low dispersion (ED) element to minimize chromatic aberrations and color fringing, and one aspherical element to reduce spherical aberrations for crisp, clear images. Additionally, the lens is equipped with a Nano AR Coating, which reduces flare and ghosting, improving contrast and color fidelity, especially in challenging lighting situations.

The lens offers precise and fast autofocus, powered by the Direct Drive Super Sonic Wave Motor (DDSSM), which is quiet, accurate, and responsive. Its internal focus mechanism helps maintain the lens’s compact size during operation. The lens also offers macro capabilities, with a switchable focus range that allows users to choose between a general focus range (2.8 feet to infinity) or a closer range (1.9 to 3.3 feet), providing a maximum magnification of 0.25x for stunning close-up detail.

Built with a dust- and moisture-sealed design, the lens is rugged and capable of performing in challenging environments. It also features Optical SteadyShot (OSS) image stabilization, enhancing handheld shooting stability in low-light conditions, further complemented by a de-clickable aperture ring for smooth, silent aperture adjustments, especially useful for video work.
