Key Features
- EF-Mount Lens/Full-Frame Format
- Aperture Range: f/1.8 to f/22
- Two Aspherical and Three ED Elements
- Ultra Multi-Coating
Designed for Canon EF-mount DSLRs, this 20mm f/1.8 ED AS UMC Lens from Rokinon is a bright wide-angle prime featuring an intuitive manual focus design and enhanced optical construction. Two aspherical elements and three extra-low dispersion elements are used to reduce both spherical and chromatic aberrations for greater sharpness, clarity, and reduced distortion. The optics also feature an Ultra Multi-Coating to guard against lens flare and ghosting for increased contrast and color neutrality when working in strong lighting conditions. The manual focus operation affords working with subjects as close as 7.9" away, and a rounded seven-blade diaphragm contributes to a pleasing bokeh quality.

Is the compatible with Canon EOS R5 with an EF adapter?
Yes, the Rokinon 20mm f/1.8 ED AS UMC Lens for Canon EF will work on the Canon R5 camera when using the Canon EF to RF adapter. But because there are no electrical contacts on the Rokinon lens, the R5 would need to be set to shoot without a lens. Also it will only work in aperture or manual exposure modes.

Is it possible to use an 82-77 mm step down ...
Is it possible to use an 82-77 mm step down filter adapter so I can use the lens with an 82 mm screw on filter?
A step-down filter is designed to use a smaller filter on a lens with a larger filter thread. As such, you would not use a step-down filter to connect an 82mm filter on a 77mm lens filter thread. You would instead need a 77-82mm step-up filter to connect an 82mm filter on the lens' 77mm filter thread. However, do note that if you use a step-up filter, you may not be able to use the lens hood and may need to remove the lens hood from the lens before using the larger filter setup. The Sensei 77-82mm Step-Up Ring, B&H # SESUR7782, would allow you to use an 82mm filter on the Rokinon 20mm f/1.8 ED AS UMC Lens for Nikon F.
