Simon Sommer, ZEISS Service Trainer and Technician hosts an instructional video detailing how to install the ARRI/ZEISS Master Anamorphic Flare Sets.
Simon uses the 60mm Master Anamorphic lens to demonstrate how to put the Flare Set on. It is the same for all focal lengths in the Master Anamorphic lens series.
The front and rear glass elements that come with each flare set have a special lens coating that encourages flaring, ghosting and veiling glare. These image effects create a visual style that is consistent across all of the flare sets and can be controlled or tweaked via the iris setting, as well as the positioning of lighting fixtures.
The front element can be used on its own, as can the rear, or they can be used in combination; each permutation provides a distinct look without sacrificing the resolution, lack of distortion or corner-to-corner optical performance for which the Master Anamorphics are famous.
