Optical Design
- Bright f/1.8 maximum aperture allows for fine-tuned control over depth of field and also benefits working in difficult lighting conditions.
- One extra-low dispersion element is featured in the optical design and helps to limit color fringing and chromatic aberrations for heightened image clarity and color accuracy.
- The rounded nine-blade diaphragm contributes to a pleasing bokeh quality when employing selective focus techniques.
Autofocus and Handling
- Double linear autofocus motor delivers smooth, precise, and near-silent focusing performance to benefit both stills and video applications.
- The focus hold button on the lens barrel can be used to hold the focusing position, or can be set in-camera to control a variety of additional lens functions.
- AF/MF switch for tactile control over the focus mode.
- Dust- and moisture-resistant design for increased protection from the elements.
