New in RingThing
Generate focus, iris and zoom ring scales from any supported LDA lens data file (currently ARRI, cmotion or Tilta, with more in development), share them by QR code and keep your library organised — all on your iPhone.
Bring LDA files in from Files, AirDrop, iCloud or any cloud provider — the share extension does the rest.
Turn focus, iris and zoom data straight into ring scales — no more marking rings by hand.
Every lens file becomes a scannable QR — no account needed, no AirDrop dance.
Your LDAs are always accessible — grouped by manufacturer, type, focal length and serial.
Built for camera teams
Pull LDA files in from Files, AirDrop, iCloud Drive or any cloud provider — the share extension hands them straight to RingThing.
Each archive keeps its focus, iris and zoom curves intact so the lens behaves on set exactly the way it was calibrated.
Rename the archive, add notes about the lens, body or session, and it slots into your library ready to share.
Pick an LDA from your library and RingThing builds focus, iris and zoom ring scales straight from the calibration data.
No more eyeballing distances against a printed table or marking rings by hand — the marks land exactly where the lens says they should.
Send the scales to a cutting machine using RingThing's existing export workflow, or share the underlying LDA so a colleague can do the same.
Every LDA in your library becomes a scannable QR code. Tap to send, or hold up the screen during prep.
Anyone with the app and a scan has the same lens data you do — no AirDrop dance, no email attachments.
Scanning opens the RingThing app instantly on iPhone. On any other device the link inside the QR lands here, so the recipient can grab the app and import the archive.
LDA files are organised automatically by lens manufacturer, type, focal length and serial.
Mark favourites for the lenses you reach for most, and archive the ones you don't need cluttering the list.
Everything stays on your phone — your library is yours, no sign-in, no cloud sync to manage.
