They can't, Anamorphic lenses are
profoundly weird - their flare characteristic is from a visual perspective, inherently more distracting than spherical lenses due to the geometry of the lenses. The matte boxes used for cinematography purposes are always an extendable
rectangular bellows.This extension is important for managing stray light, as ruining several hundred feet of film is a bigger catastrophe than a single 35mm frame. Standard aspect ratio for these matte boxes is 16:9 - though cinematographers use front mounted masks for exotic formats like 5:4, 4:3, 2:35.1(CinemaScope) and 2:39.1
