Viltrox PFU RBMH 20mm f/1.8 ASPH Lens for Nikon Z

Featuring an expansive field of view and a vibrant design, the PFU RBMH 20mm f/1.8 ASPH by Viltrox is an ultra-wide prime lens tailored for Nikon Z-mount mirrorless cameras. The wide-angle configuration and rapid f/1.8 maximum aperture render it particularly suitable for astrophotography, as well as for landscape, interior, and architectural photography. Its optical architecture includes a combination of aspherical and low dispersion elements, which mitigate spherical and chromatic aberrations, resulting in sharp, well-corrected images with precise color reproduction. Furthermore, an HD Nano multi-layer coating has been applied to minimize flare and ghosting, enhancing contrast when shooting in bright lighting conditions. The lens features a manual focus mechanism, allowing for close-up work with subjects positioned as near as 9.8 inches, and its 14-blade diaphragm enhances the quality of bokeh. Additionally, it is constructed from brass, ensuring durability and smooth functionality.

• 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.
