Full-frame Lens: The Viltrox 35mm F1.8 wide-angle lens is designed for full-frame format Nikon Z mirrorless cameras, and when used with APS-C format cameras, it has the equivalent perspective of a 52.5mm lens. | Large Aperture: Bright f/1.8 maximum aperture suits working in low-light conditions and also affords greater control over the depth of field. The Nine-blade diaphragm contributes to a pleasing bokeh quality. | Excellent Optical Design: The optical design incorporates two extra-low dispersion elements and two aspherical elements, which combine to suppress a variety of aberrations and produce high sharpness, clarity, and color accuracy, and two high refractive index elements are included to suppress a variety of aberrations and distortion. | STM Stepping Motor: STM stepping motor enables quick, quiet, and precise autofocus performance along with full-time manual focus override. Additionally, an internal focusing design maintains the overall lens length during use for improved handling and quicker response. | Integrated Manual Aperture Ring: Integrated manual aperture ring for tactile exposure control; this ring also features an 'A' position for automated, camera-based aperture selection. You can control the aperture, shutter, depth of field, and exposure through the camera body, and realize the information sharing between the camera and the lens.
