Description vastus 2017-05-14 18:13:17 UTC 
I own a Pentax camera which is capable of producing DNG-Files. Unfortunately i had left the "convert raw files to dng"-option enabled when importing which converted all my DNG files to DNG files but deleting Makernotes in the process so that all the new DNGs now have missing lens information.
I think a warning when trying to convert from DNG to DNG would be a good idea (maybe mentioning the possible loss of metadata) as this took me quite some time to track down (at first i thought that the camera did no longer encode the lens used, then i realised that the information was there in the jpeg files but not the dng ones and finally i realised that i had left the conversion option enabled).
