EZ-3 is a new telephoto lens in the Angenieux EZ line of professional film optics! Like the EZ-1 and EZ-2 models, it offers compact dimensions, excellent drawing, dual focusing marks and above all the "IRO Technology" (Interchangeable Rear Optics) which allows to interchange the rear part of the optical system to convert the lens for S35 or FF/VV cameras. Thanks to the innovative design of the rear element, the exchange itself is very easy and takes about 5 minutes. The EZ-3 Pack includes both (S35 and FF/VV) rear elements for optical parameters 45-165 mm T/2.3-3 (S35) and 68-250 mm T/3.5-4.5 (FF/VV) respectively! The lens comes standard with a PL (interchangeable) bayonet, optional EF, RF and E interchangeable bayonets are also available.
