Lens Labeler

The lens you really used, in every photo.

Cameras can’t recognize manual and third-party lenses, so they record a guess, the profile you picked, or nothing at all. Lens Labeler writes the lens you really used into your photos, so Lightroom, Photos and everyone you share with see the right one.

What it does
Originals stay untouched

Lens Labeler writes a corrected copy in the same format: a DNG stays a DNG, a TIFF a TIFF, a JPEG a JPEG. Nothing is re-encoded, and the image data is checked byte for byte.

Batches, grouped by lens

Add up to 100 photos from Photos, Files or a whole folder. Set the real lens once per group, and save it so it fills in automatically next time.

A lens catalog

Pick from a built-in catalog of M-mount lenses, or type in any lens: brand, model, focal length and maximum aperture.

Film scans

Add the camera, film stock and ISO to a roll of scans, plus the date it was shot. Save a setup as a preset for the next roll.

Content Credentials (C2PA)

For photos that already have them, strip them or re-sign the copy on your iPhone, keeping the camera’s original signature in the history.

Private by design

No account, no analytics, no network calls. Your photos and your lens list never leave your iPhone.

How it works
  1. Add your photos

    From Photos, Files or a folder. DNG, TIFF and JPEG.

  2. Set the real lens

    Once per lens group, from the catalog or typed in. Add film details for scans.

  3. Save the copies

    Write corrected copies and save them to Photos or Files. Your originals stay as they are.
