These adhesive-back lens scale tapes are applied over the stock Focus, Iris, and Zoom scales on the Angenieux 24-290, or the Iris and Zoom scales of the Angenieux 17-80, Cooke 25-250, 18-100 and 20-100 lenses.  They correct for the magnification changes when either the Super 35 to S35 Open Gate, or Super 35 to Full Format Xpander is installed on the lens. The tapes are removable and reusable. Send us a message describing which lens you need the scales to fit.
