But maybe Adobe and other raw converters can put in a fix to work around the problem. If the DNG files are improperly coded, they are hosed forever. So of course I could apply any distortion correction I wanted – C1 is just morphing the image! Oh, so this is a generic? OK, let me balloon up or down the middle when you slide the bar left or right!!! But when I set the lens to the proper profile (e.g., “Leica Summilux-M 50mm f/1.4”), then sliding the Distortion bar has zero effect Mystery partly solved: for whatever reason, the M11 images are coming into C1 with the lens properly identified in the Information tab (which also shows the EXIF), but shown as “Generic” in the Profile section under the Lens tab. Roy P confirms the same problem in PhaseOne CaptureOne Pro: Something about the M11 DNG causes Iridient Developer to fail to find the matching lens profile. It can correct distortion for M11 DNG files, once the matching lens profile is manually chosen*. But setting the lens profile to a Zeiss ZM or Voigtlander VM lens causes distortion correction to start working. For example, setting the Leica 18/3.8 to any other Leica lens invokes no change. And of course the correction is the wrong one. That is, for any coded lens for which ACR selects a matching lens profile, selecting *any* Leica-M lens profile makes distortion correction have no effect no matter the percentage setting.Īnd yet ACR is fully functional for a DNG file from the exact same lens shot two months ago on the Leica SL2.Ĭuriously, manually choosing a different (incorrect) lens profile causes the distortion correction to operate, but only if it is a non-Leica lens profile. Whether set to 0% or 100% there is no distortion correction. As if the lens coding problems in the M11 were not bad enough.Īdobe Camera Raw (ACR) is non-functional for distortion correction with Leica M11 DNG files. Just another example in the decade-long history of sloppy firmware development at Leica and poor quality asssurance. Adobe Camera Raw Optics panel: distortion correction has no effect
