The problem seems to be that we do a lensfun search with LF_SEARCH_LOOSE when we try to find a lens. I don't know what lensfun does exactly then, but I assume it will just try to find the closest match, whatever that is. In this case it is: lens: A-Serien Linsen, maker: Carl Zeiss, model: VCL-MHG07a That's way off. All is still OK in the beginning, as long as the camera name is not set manually. The camera is not found, because we are looking for an exact camera match. If module lens correction does not get an exact match in the database no correction is applied. As soon as the camera is manually selected, our module assumes all is good and a correction is done. However, with the wrong choice of a lens :( I was not involved, but we probably do the loose search in order to overcome variations in writing when in comes to the lens names. Probably it was found that all too often a lens was not detected although it was existing in the database with a slightly different spelling. Not sure how we can overcome this situation. One solution could be a blacklist of lens names which libexiv2 will typically report if the photo was taken with a pure mechanical lens. If the lens is one of those we avoid any automatic detection. I fear that the blacklist might get quite long. On my system for the two incumbent files the lens is reported with a German string, even if I start darktable with LANG=C. Different cameras will have different strings etc. Ulrich ------------------------------------------------------------------------------ Symantec Endpoint Protection 12 positioned as A LEADER in The Forrester Wave(TM): Endpoint Security, Q1 2013 and "remains a good choice" in the endpoint security space.
