Sony SEL-100F28GM.SYX E Mount Full Frame Lens

Delivering both smooth bokeh and fine sharpness, the FE 100mm f/2.8 STF GM OSS Lens from Sony is a short-telephoto prime featuring a unique, yet sophisticated optical design. Separating itself from other portrait-length lenses, this 100mm f/2.8 features Smooth Trans Focus technology, which uses an apodization filter to realize notably smooth bokeh with rounded out-of-focus highlights in both the foreground and background. Contributing to a high degree of sharpness and clarity, the lens also incorporates one aspherical element and one extra-low dispersion element to suppress both spherical and chromatic aberrations. Additionally, a Nano AR coating has also been applied to reduce lens flare and ghosting for greater contrast and color fidelity when working in strong lighting conditions.

Complementing the optics, this lens also sports a robust physical construction that is dust- and moisture-sealed for use in trying conditions. It is also an apt performer, and utilizes a Direct Drive SSM to afford quick, quiet, and smooth autofocus performance. A ring-switch permits selecting between two focusing ranges, including a dedicated close-up range for working with subjects as close as 1.9′ away with a 0.25x maximum magnification. Additionally, Optical SteadyShot image stabilization further contributes to producing sharp images when shooting handheld by minimizing the appearance of camera shake.

Short telephoto prime designed for full-frame Sony E-mount mirrorless cameras, however it can also be used on APS-C models where it will provide a 150mm equivalent focal length.

Optical design incorporates an apodization element that helps to improve the quality of bokeh. This element, which resembles a radially graduated ND filter that tapers from clear in the center to more dense around the edges, produces more circular out-of-focus highlights for more pleasing selective focus and shallow depth of field effects.

An aperture range of f/2.8 to f/20 is available, however the implementation of the apodization filter renders this range as T5.6 to T22.
