Description by Zak Ray Written by the developer, not by AppBrain. Click to read.
Whether you’re planning a shoot or making decisions on set, LensKit has you covered. Search over 2000 lenses from Angenieux, Arri, Cooke, Hawk, Leica, Zeiss and more. All specs and data sourced by hand: no AI means no hallucinations.
SPECS
Includes max aperture, lens mounts, weight, length, close focus, front diameter and more*
COVERAGE
Overlay a lens’ image circle on your camera sensor to make sure it’s covered. 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. Group together lenses you rent or own for quick access.

To see all supported cameras and lenses, just install the app (it's free to download!) and open the main dropdown menu.
No internet connection required: all data is hard-coded into the app, so there’s no syncing process, and you’ll be able to access it even without a cell signal.

*Every lens in this app has complete specs, with the exception of some Panavision lenses. 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)
