Includes over 200 cameras from Arri, Canon, Red, Sony, Blackmagic, Panasonic and more* LENS MATCH Mix and match spherical, anamorphic, speed boosters and extenders, and even factor in post-production extractions— the lens match tool can handle it all. EQUIVALENT No need to worry about crop factors or sensor sizes, just choose a focal length and a camera and get the Super35 equivalent. Or pick the S35 equivalent length you want and see the lens you’ll need. NETFLIX APPROVAL A game changer for anyone who’s struggled with the complexity of which formats and resolutions meet the Netflix "4K mandate"— especially when shooting in anamorphic. Designed in collaboration with Netflix. DEPTH OF FIELD An easy to use yet comprehensive DOF tool that allows for customizing circle of confusion with presets and manual input. PREVIEW See a simulation of your shot based on lens, camera and distance. Or pinch, zoom and reposition to get the exact frame you want, and see what lens or distance you’ll need for it. AND MORE Filter lenses to see only what fits your specific camera and needs. Save your calculations and return to them later.

We’ve chosen to include these incomplete lenses in the app because of Panavision's importance in the industry. Additionally, while the large majority of lenses have exact image circle data, some—especially some vintage lenses—list only generic format coverage (e.g. Super35, Full Frame, etc) EULA: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
