Revar Cine 138mm / 37mm Close-Up Donut Diopter +2

The 138mm, +2 Close-Up Donut Diopter from Revar Cine uses high-quality Schott BK7 glass with an index similar to your lens elements. This unique close-up lens is made from the same high-quality glass as round drop-in close-up lenses, and it can be quickly and easily inserted in a matte box.

It is useful for quickly getting the right shot with a variety of lenses having different focal lengths, including large-diameter prime lenses and zoom lenses.
