When pairing with the OOOM, Laowa 1.33X Rear Anamorphic Adapter allows expanding your filming canvas to a  2.35:1 cinematic widescreen ratio in a 16:9 sensor while retaining its image resolution.   It adds special characters in bokeh and flares on ordinary spherical lenses to become more cinematic.

A half stop light impact on the lens after the anamorphic adapter is applied.
This anamorphic rear adapter doesn’t feature any oval bokeh or expanded horizontal field of view like front anamorphic lenses does.
