Version: 1.5.0 OS: Linux I converted CR2 files to dng and found for example the lense data missing, which is bad because automatic lense correction tools won't work. I also converted the file with adobes converter, the resulting dng has the lense data, however it does not show up in darktable so it seems not to be in the field where it is in the CR2. Some makernotes fields of the Kipi-created dng also look messed up: Dateiname: IMG_3172.dng (Herstellerbemerkungen in Exif-Informationen) >>> Canon <<< Firmware Version : f:li> <rdf:li>8</rd Focal Length : 26214 21306 28001 27760 Image Type : <rdf:li>8</r ModelID : (2147484022) Owner Name : f:li> </rdf:Seq> </tiff:B Serial Number : 259102726 I attached the original CR2 and the two DNGs. Reproducible: Always
Lens info are normally registered in Canon makernotes. Makernotes are saved in DNG files. Which Exiv2 library version you use exactly ? Can you parse all metadata from CR2 and DNG with Exiftool to see the difference. Thanks in advance Gilles Caulier
Created attachment 52836 [details] metadata of the 3 files
exiv2 is 0.19-1, Metadata from Exiftool is attached.

Created attachment 73340 [details] exifdata of a cr2 and the corresponding dng
Just recognized that the I have the problem again, EOS7D CR2s converted to DNG with DigiKam/Kipi 2.8.0 don't show lens info metadata in Darktable 1.0.5. While I see the Info in the Exiv Data (see attached files) at least some fields are messed up. Here an example: DNG: Field Of View : 9.2 deg Focal Length : 35.0 mm (35 mm equivalent: 222.8 mm) Hyperfocal Distance : 46.34 m Lens : 18.0 - 55.0 mm (35 mm equivalent: 114.6 - 350.1 mm) CR2: Field Of View : 36.3 deg Focal Length : 35.0 mm (35 mm equivalent: 55.0 mm) Hyperfocal Distance : 11.43 m Lens : 18.0 - 55.0 mm (35 mm equivalent: 28.3 - 86.4 mm)
Using DigiKam 4.1.0/Kipi plugins 4.1.0 I have the same issue, not for all CR2 images, but for about 3 out of 100 CR2 images the DNG does not contain the right metadata, furthermore these DNG images are then also not shown when filtering on either RAW or DNG images. When retrying with a subset of images, each time the same DNG images will be corrupt. I will add an example CR2, DNG and xmp file as attachment.

Sander, This file still valid using last kipi-plugins 4.10.0 ? Gilles Caulier
Gilles, This file is probably related to Bug 338842 Sander
*** Bug 338842 has been marked as a duplicate of this bug. ***
New kipi-plugins 4.11.0 is available : https://www.digikam.org/node/740 Can you reproduce the problem with this release ?
This problem is not reproducible with last 5.0.0 I close this file now. Re-open it if necessary. Gilles Caulier
