3. Creative Use

With its 2x squeeze, the lens delivers the classic widescreen character: pronounced horizontal streaks in blue and cyan, oval bokeh shapes, and caustic flares in backlight. Barrel distortion is noticeable at 75mm but typical for vintage wide-angle anamorphics. As an uncoated vintage glass, it operates with low native contrast – good for subjects requiring soft shadows and atmospheric depth. Rentals are usually through specialized vintage rental houses; rehousing is not standardly documented, so it's advisable to check the focus mechanism and sharpness performance on your own set before shooting.
