Flattener / FLAT6AIII reducer, 0.8x, version for William Optics FLT 91

The adjustable William Optics Flat 6AIII flattener supports the maintenance of uniform image quality, both in the center and on the edge of the frame, by eliminating the negative influence of the refractor's optics, as a result of which, as you move away from the center of the frame, sharpness gradually deteriorates "flatness" of registered objects.

This product also acts as a reducer, allowing the focal length to be shortened by 0.8x. The diameter of the illumination circle is about 44 mm, which makes it possible to successfully use this flattener with cameras and full-frame reflex cameras.
