Irix Cine Front Lens Cap for Irix 45mm New Irix lens caps were designed to fit 95 mm diameter Irix Cine lenses. This allows you to keep your lens case neat and organized. They come fitted for each lens with visible markings on top. Thanks to that solution you will know exactly what lens you are reaching for after opening the case.
A flat-top allows for leaving your lens standing on the cap, making it much more secure than standing them on a much more narrow bottom lens cap.
