Viltrox PFU RBMH Manual Focus 20mm f/1.8 ASPH Lens for Nikon Z Mount Z5/Z50/Z6/Z6 II/Z7/Z7 II/Z9/Zfc - VL-20MM F1.8-MF

• Ultra-wide prime is designed for FX-format Nikon Z-mount mirrorless cameras. however, it can also be used with DX models where it provides a 30mm equivalent focal length. Bright f/1.8 maximum aperture suits working in difficult lighting conditions and also offers increased control over depth of field. Four extra-low dispersion elements, one double-sided aspherical element, and one element made from highly transparent glass all contribute to reducing a variety of aberrations in order to produce a well-corrected image with accurate color and high sharpness. HD Nano multi-layer coating has been applied to individual elements to reduce flare and ghosting for improved contrast. Also, this coating is water resistant to help protect the exposed surfaces from moisture. Manual focus design, with a 148.5° focus throw, permits working with subjects as close as 9.8" away. Engraved focus distance and depth of field scales benefit working with prefocus and hyperfocal focusing techniques. A 14-blade diaphragm contributes to a pleasing bokeh quality. Brass lens barrel construction realizes a physically durable design that also affords smooth operation. Included lens hood helps to prevent flare and also affords some protection to the bulbous front element. Additionally, a filter adapter ring is included for mounting 82mm screw-in filters.
