• Based on the ZEISS Sonnar optical concept, this lens uses a design with seven elements in five groups that helps achieve the large maximum aperture of f/1.8 while simultaneously reducing flare and improving contrast.
• Bright f/1.8 maximum aperture allows users to create images with shallow depth of field and work in low-light conditions with relative ease.
• Three aspherical elements, including two double-sided, are incorporated in the lens design to reduce astigmatism, field curvature, coma, and other monochromatic aberrations.
• ZEISS T* anti-reflective coatings have been applied to each lens surface to help minimize reflections in order to provide greater image clarity, contrast, and color fidelity.
• Rounded nine-blade diaphragm contributes to a pleasing bokeh quality when employing selective focus techniques.

Autofocus and Design

• Linear autofocus motor and internal focus design provide quick and precise autofocus performance and enables accurate and silent focusing while recording videos.
• Dust- and moisture-sealed design better permits working in inclement conditions and rubberized control rings benefit handling in colder temperatures.
