Diopters Schneider Optics

Description

Generally, diopters are lens attachments that shorten the close focus distance of lenses by reducing the focal length of the optical system. Their strength is given as reciprocal of focal length in meter (so called diopter), e.g.:
+ 1 diopter = 1 meter infinity focus plane
+ 2 diopter = 0.5 meter infinity focus plane

Here at Schneider-Kreuznach we offer three different types of diopters:

Diopter Full
Classic full diopters reduce the close focus distance and even allow you to take macro images without using a dedicated macro lens.

Diopter Split
A split diopter is a standard diopter element which is precision-cut in half and mounted in a ring. It allows you to focus both fore- and background at the same time. Hence, it can attract the viewer’s attention to an object in the back while the main scene remains focused.

Diopter Spot
Basically, a spot diopter is a classic diopter with a plain, polished area in its center. This leads to a sharp image in the middle and an out-of-focus area towards the edges. For dreamy images with an in-focus center.
