A well-rounded prime for portraiture, the Sony E-mount atx-m 85mm f/1.8 FE from Tokina is a versatile short-telephoto lens mixing a bright design and popular focal length. The f/1.8 maximum aperture suits working in difficult lighting and benefits depth of field control as well as helps to maintain a portable form factor for everyday shooting. A low dispersion element is incorporated into the optical design to reduce color fringing and chromatic aberrations and a Super Low Reflection Multi-Coating has been applied to suppress flare for heightened contrast and color accuracy in strong lighting. An ST-M autofocus system achieves fast and near-silent focusing performance and a nine-blade diaphragm also contributes to a pleasing bokeh quality to suit selective focus imagery.
Portrait-length prime is designed for full-frame Sony E-mount mirrorless cameras but can also be used with APS-C models where it provides a 127.5mm equivalent focal length.
Bright f/1.8 design strikes an ideal balance between portability and a fast design and maintains a sleek profile while benefitting depth of field and low-light shooting needs.
One SD low dispersion element is featured in the optical design and helps to control chromatic aberrations and color fringing for improved clarity and color accuracy.
Super Low Reflection Multi-Coating reduces ghosting and flare for increased contrast and color fidelity and also helps to repel water, oil, and dust from the front lens element.
ST-M stepping motor achieves fast and especially quiet autofocus performance and the all-metal focus unit also contributes to a dampened manual focus feel for improved control. Additionally, this system uses an internal focusing mechanism to limit the overall length of the lens and to promote faster focusing speeds.
Nine-blade diaphragm contributes to a pleasing bokeh quality.
The lens mount is fitted with an electronic interface that conveys all lens Exif data to the camera and is also fully compatible with in-camera functions, such as image stabilization, Eye AF, MF assist, and other functions.
