iOS 17.4 + iPhone 15 Pro Max: Main Camera Lens Metadata Change Prevents Auto Lens Profile Correction

[Joseph Kohlmann]

Greetings!

I've discovered that iOS 17.4 changed the lens metadata for the iPhone 15 Pro Max's Main Camera (which Apple's specs describe as: "48MP Main: 24 mm, ƒ/1.78 aperture"):

• iOS 17.3.1: iPhone 15 Pro Max back triple camera 6.86mm f/1.78
• iOS 17.4: iPhone 15 Pro Max back triple camera 6.765mm f/1.78

Specifically, the focal length metadata has changed from 6.86mm to 6.765 mm.

This change prevents Lightroom Classic 13.2 Build [202402141005-bflaeb84] from locating a matching lens correction profile automatically.

The workaround is to apply the matching lens profile manually:

• Make: Apple
• Model: Apple iPhone 15 Pro Max back camera 6.86mm f/1.78
• Profile: Adobe (Apple iPhone 15 Pro Max back camera 6.86mm f/1.78)

For metadata reference only, I've attached two exported JPEGs for reference (one representing a source image from iOS 17.3.1, and the other from iOS 17.4). Note that the change affects the original HEIFs and ProRAW DNGs, obviously (neither of which I can attach for some reason).

I really appreciate LrC's lens profile corrections and the ability to automatically apply them, so I'd love to see a fix. Thanks!

After you have matched the profile manually, click on 'Custom' and choose 'Save New Lens Profile Defaults'. This should make Lightroom Classic apply the lens profile automatically again.

Thank you so much for this much better workaround, @JohanElzenga! This did the trick, though I had to choose "Save New Lens Profile Defaults" multiple times (maybe due to some Main Camera shots that were "2× Camera" crops, not sure).

Would still like to see a fix from Adobe, though obviously they have nothing to do with Apple's metadata change.
