Standard Zoom Lens:
Designed for FX-format Z-mount mirrorless cameras, providing a versatile zoom range from wide-angle to portrait-length.
Constant f/4 Maximum Aperture:
The lens features a constant f/4 maximum aperture, ensuring consistent performance throughout the zoom range. This contributes to the lens’s relatively lightweight and compact design compared to faster f/2.8 zoom lenses.
Optical Design:
Incorporates a unique aspherical extra-low dispersion element, along with three additional aspherical elements, to minimize chromatic and spherical aberrations, distortion, coma, and flare. This results in edge-to-edge sharpness and illumination.
Coatings:
Nano Crystal Coat and Super Integrated Coating are applied to lens elements to reduce surface and internal reflections, minimizing lens flare and ghosting for improved contrast and color rendering, especially in bright and backlit conditions.
Stepping Motor Autofocus:
The stepping motor delivers smooth, quiet, and fast autofocus performance suitable for both stills and video applications. Full-time manual focus override is possible, and the internal focusing design maintains the lens’s overall length for faster focusing speeds.
Programmable Control Ring:
The lens features a programmable control ring that can be set to adjust manual focus, aperture, or exposure compensation, providing intuitive control over various camera and exposure settings.
Electromagnetic Aperture Mechanism:
The specialized electromagnetic aperture mechanism enhances exposure control stability, particularly beneficial for fast continuous shooting rates.
Dust- and Moisture-Resistant Design:
The lens barrel is dust- and moisture-resistant, making it suitable for use in various environmental conditions.
Fluorine Coating:
Elements of the lens feature a fluorine coating, providing protection against dust, grease, and water droplets.
Button-Less Retractable Design:
The lens has a button-less retractable barrel, contributing to a more compact form factor when the lens is not in use.
Rounded Seven-Blade Diaphragm:
The rounded seven-blade diaphragm promotes a pleasing out-of-focus quality, supporting the use of shallow depth of field and selective focus techniques.
