    • Bright f/2.8 maximum aperture suits working in difficult lighting conditions, benefits astrophotography applications, and also affords greater control over depth of field.
    • One ultra-low dispersion aspherical element and one anomalous partial dispersion element noticeably reduce color fringing and chromatic aberrations in order to achieve high clarity and accurate color rendering.
    • Two aspherical elements, including the UD aspherical element, and an ultra-high refractive index element help to minimize distortion and spherical aberrations for greater sharpness and accurate subject rendering. Individual glass elements are multi-coated to resist flare and ghosting for improved contrast and color fidelity.
    • A DC motor is used for quick and accurate autofocus performance, and a dedicated switch lets you quickly change from AF to MF control. A focus distance scale is also featured to aid with pre-focusing techniques.
    • Chrome-plated metal lens mount is durable and accurate for a secure fit with the camera body, and gold-plated contacts help to ensure consistent communication between the lens and camera.
    • Seven-blade diaphragm contributes to a smooth bokeh quality.
