## What is LensKit?

Professional lens tools from the developer of CameraKit and FinderKit. 

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.

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.

*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)

### 5/5 — Best tool to check coverage

*2025-03-05*

Way more lenses than other apps/websites

### 5/5 — Love it! The ideal app for lenses

*2025-03-03*

I mean it when I say LensKit is an essential tool for anyone working in cinema or television production. It offers a comprehensive database of lenses, making it easy to compare specs and determine the right choice for your project. It even has the ability to check lens coverage, ensuring compatibility with your camera, includes a Field of View preview and a Depth of Field calculator, both incredibly useful for planning shots. If you need to match lenses across different cameras, the lens matching tool simplifies the process while integrating seamlessly with CameraKit, making it even more versatile.
A must-have for industry professionals, highly recommended!

### 5/5 — Great App

*2025-01-27*

Update fixes the app. Great app, just wish the free version allowed you to choose one lens without having to update to the subscription version.

**Developer response:** Just fixed in the latest update!

### 4/5 — Latest Version Crashes

*2025-01-24*

Latest version crashes while loading on my iPhone 15 Pro Max but otherwise a fantastic app.

### 5/5 — Pleaseeeeee

*2024-05-24*

I work as a vfx supervisor and the function of copying lens data to the clipboard would be very useful to me!!!!

**Developer response:** Feel free to email me at zak@grayhourmedia.com to discuss!

### 5/5 — Pro tool with simple UI and great dev response

*2024-02-11*

I bought the one time payment app, as I'm not pro subscription. But great, barebones UI, very full and complete database of lenses and cameras. The app also has the ability to mix and match lenses to create a unique SET/KIT (for out of series lenses for example). Responsive developer. Overall I'm very happy with the app. Of course, there's room for improvement, but for a 1.1 version, it is extremely promising. Keep up the great work and thank you!

### 1/5 — Infuriating

*2023-02-14*

Paid the subscription, and all Canon items still locked. You tap the ‘restore purchase’ and it just keeps sending you round in circles. Terrible app design.

**Developer response:** Very sorry about this. Please send me an email at zak@grayhourmedia.com so I can make it right!

### 1/5 — Bien mais beaucoup trop cher

*2022-10-13*

L'application est top mais son prix n'est pas justifié, surtout qu'il est incohérent de pouvoir avoir les 2 applications en payant 3,49€ par mois mais IMPOSSIBLE en payant à vie les 59€. Vous devriez permettre d'accéder aux 2 applis en ne payant qu'une seule, meme pour l'achat lifetime.
Du coup je ne met qu'une étoile. Dommage.

**Developer response:** désolé que vous vous sentiez comme ça, c'est beaucoup de travail pour garder les applications à jour, et je ne peux pas le faire gratuitement.

### 3/5 — Great app, but crashes when restoring purchase on the new iPad Mini

*2022-07-11*

Great app, but crashes when restoring purchase on the new iPad Mini

**Developer response:** This was fixed in the latest update! If you're still having trouble please contact me at zak@grayhourmedia.com

### 5/5 — Amazing and Useful

*2022-05-03*

Wonderful database of cinema lenses! Amazing tool for helping to figure out the right lens selection for your production. Not only can you compare specs, but you can check the coverage of the lens go make sure it will work with the camera you’re shooting on. Then you also have a very handy Field of View preview and Depth of Field calculator. Need to match two lenses on different cameras? There’s a lens matching tool that’s super helpful for that. I love this app. It also works great with the CameraKit app. Must have for working cinema and television professionals.
