Properties ofoptical glass

As a manual focus and manual aperture lens, it provides a wide, easy-to-grip focus ring and bright aperture, distance, and depth of field markings for precise adjustments. The internal focus system maintains the lens’s compact design and prevents the front element from extending during focus. This lens is constructed with a sturdy metal barrel, ensuring durability, and comes with a removable petal-shaped lens hood to further reduce lens flare and protect the front element.

Ohara currently melts more than 130 environmentally safe glass types, free of both lead and arsenic and produces more than 300 tons of high quality optical glass each month available as strip, slab, cut blanks, pressings and other forms.

Rokinon 12mm f/2.8 Fisheye Lens EF Mount features a sophisticated optical design with 12 elements in 8 groups, including three elements made from low dispersion ED glass and two aspherical elements. These elements work together to minimize chromatic aberrations and coma, ensuring sharp and color-accurate images. Additionally, the lens employs highly effective nanocrystal anti-reflection (NCS) coatings along with ultra multi-coatings (UMC) to improve light transmission and reduce ghosting and flare, resulting in higher quality images.

This ultra wide-angle fisheye lens, with its 12mm focal length on full-frame cameras and a 19.2mm equivalency on APS-C format cameras, is ideal for a variety of wide-angle applications, including interiors, landscapes, group shots, and creative experimentation. More
