The Angenieux EZ-3 68-250mm & 45-165mm Cinema Zoom Kit is a compact PL-mount zoom lens that includes Super35 and FF/VistaVision external lens sets, to make your cine- style camera. Just edit some pages to use this versatile 3.7x ratio zoom with the format you want in any project. 
This lens features an industry-standard 0.8 MOD focus, iris and zoom gear for compatibility with the follow focus unit and lens control motor. The 114 mm tip diameter allows you to work with matte boxes supported by a rod.

Exchange surfaces
Angenieux’s new high-speed IRO (Interchangeable Rear Optics) system provides a solution for compact, two-to-one sensor format compatibility.
The S35 being screw-mounted along with the full-frame/ VistaVision own optical section can be changed in the field by users.
Expander: The full-frame backset also acts as a 1.5x expander for S35 capture.
No crop factor: 22mm/T3 wide angle for the largest cameras inside turns the lens to 15mm/T2.0 for S35 cameras, and maintains the same viewing area with an added advantage over the T-stop
Lens Mount Interchangeable
 Fast maximum aperture
The slightly faster T2.3 maximum aperture on the Super35 and the full-frame T3.5 allow you to shine deeper than many zooms usually require
In full frame the EZ-3 maintains a constant T-stop from 68-200mm or a constant T-stop throughout the zoo
