K&F Concept 82MM,Nano-B Series Prism Effect Filter with 3pcs vacuum cleaning cloths

Nano-B — prism filter 82 mm, breaks the image sideways and multiplies it.

• Screws onto a lens with an 82 mm thread.

The prism breaks part of the image sideways, so displaced reflections appear beside the main subject. Turning it changes which way the image mirrors and how strongly, so one scene yields several compositions. The effect happens in the lens rather than on the computer, so it can be steered while shooting.

How many reflections appear and how far apart depends on the focal length — a wide angle gives a different picture from a telephoto. The maker recommends apertures between 2.8 and 7.0; stopped far down, the prism drawing fades.
