One of Sony’s more unique lenses, the FE 100mm f/2.8 STF GM OSS is a specialized riff on an optimized portrait lens, making use of Smooth Trans Focus technology to yield an especially smooth and round bokeh. This design incorporates an apodization filter (APD element) into the optical design, which essentially functions like a radial graduated ND filter that helps achieve more circular out-of-focus highlights and more pleasing selective focus and shallow-depth-of-field effects. Beyond this distinct design, the 100mm f/2.8 has all of the traits of any other G Master lens, including advanced optics for high sharpness and clarity, a Nano AR coating, and a Direct Drive Super Sonic wave Motor AF system for quick performance. Also, balancing the relatively slow design, due to the APD element, OSS helps in reducing the effects of camera shake for sharper handheld use.
Applications: Perfect for portraiture, the 100mm focal length offers the desired length and separation, and the inclusion of an apodization filter further contributes to a smooth and pleasing aesthetic. Despite the slower design, this lens has all of the assets to flatter subjects and achieve the smoothness required for portraiture.
