Error capturing ProRAW using iPhone 17 Pro Telephoto with photoQualityPrioritization set to .Quality

Hey,

I'm having a very strange issue on my iPhone 17 Pro. I'm trying to capture a 12MP ProRAW image using the Telephoto Lens with the photoQualityPrioritization set to .Quality. Unfortunately I receive this error when trying to capture the image:

Error Domain=AVFoundationErrorDomain Code=-11800 "The operation could not be completed" UserInfo={NSUnderlyingError=0x134f7a1f0 {Error Domain=NSOSStatusErrorDomain Code=-16802 "(null)"}, NSLocalizedFailureReason=An unknown error occurred (-16802), AVErrorRecordingFailureDomainKey=4, NSLocalizedDescription=The operation could not be completed}

The photo captures correctly at 7.9x zoom, it's only a problem when the zoom goes over 8x.

Also, it's only this particular configuration of settings which causes the issue. I'm able to capture an image if I either:

  • Set quality to ".balanced"
  • Set max dimensions to 48MP
  • Capture a JPEG image instead of a ProRAW image
  • Use the TripleCamera fusion lens

Any help would be greatly appreciated.

Alex

Just to add to this, this only happens if the ISO is less than 500.
