Created to fill the wide gap between basic still photography zooms, and the highly acclaimed Optimo, Optimo Style family of lenses used in the motion pictures industry, the Angénieux Type EZ series features two new light weight zooms. Thanks to an innovative lens modular design (Interchangeable Rear Optics IRO technology™), both lenses allow the rear lens group to be exchanged between S35mm (up to 30mm image diagonal), and FF/VistaVision format (up to 46mm image diagonal).
