Re: [darktable-dev] Wrong lens detected

2017-12-07 Thread Jean-Luc Coulon (f5ibh)

The but I've opened is now closed.
There is an explanation that you can see here:
http://dev.exiv2.org/issues/1328#change-6131

Basically, you should add the following in your .exiv2 file (or add it if
it already exists):

[canon]
197=Sigma 18-300mm f/3.5-6.3 DC Macro OS HS

I've tried this on the file with the SIgma 18-300:
 exiv2 -g Lens -pt /extra/exiv2-bug-1328/IMG_4575.CR2
Exif.CanonCs.LensTypeShort   1  Sigma 18-300mm
f/3.5-6.3 DC Macro OS HS
Exif.CanonCs.LensShort   3  18.0 - 300.0 mm
Exif.Canon.LensModel Ascii  74  18-300mm
Exif.Photo.LensSpecification Rational4  18/1 300/1 0/1
0/1
Exif.Photo.LensModel Ascii   9  18-300mm
Exif.Photo.LensSerialNumber  Ascii  11  00

And it works also in darktable.

Well, with exiftool, I get :

or Sigma Lens
...
...
Lens Info   : 18-300mm f/0
Lens Model  : 18-300mm
Lens Serial Number  : 00
Lens   : 18.0 - 300.0 mm
Lens ID : Sigma 18-300mm f/3.5-6.3 DC
Macro OS HS
Lens   : 18.0 - 300.0 mm (35 mm equivalent: 28.0 - 466.3 mm)

which seems to be correct...

with exiv2 :
Exif.CanonCs.LensType Short   1  Canon EF 75-300mm f/4-5.6 IS USM
Exif.CanonCs.Lens Short   3  18.0 - 300.0 mm

Exif.Photo.LensModel Ascii   9  18-300mm
Exif.Photo.LensSerialNumber Ascii  11  00

which is confusing because the Type is only on the Canon, not "or
Sigma" but other lens data are related to the Sigma.

In darktable, it is wrong also because it is the LensType which is
reported.

My version of darktable is the latest git/trunk version

Hi,
What is the exact model of your lens (from the exif)?
Is it: "Sigma DT 18-300mm f/3.5-6.3 DC Macro" ?

If yes, it is not in version_1 of lensfun database but it is in version_2.

If you upgrade your database with the command "lensfun-update", it will
create the following in your home directory:
.local/share/lensfun/updates/version_1/
And then the lens will be in the file: slr-sigma.xml
