Description

The metadata lens field is empty for raw pictures taken with a Nikon 1 J3.

exiv2 correctly displays it:

Exif.Photo.LensModel Ascii 64 1 NIKKOR VR 10-30mm f/3.5-5.6

and also other Nikon specific data:

Exif.Nikon3.LensType Byte 1 VR
Exif.Nikon3.Lens Rational 4 10-30mm F3.5-5.6
Exif.Nikon3.LensFStops Undefined 4 8.66667

I will attach the RAW image.

History

#1 Updated by Pascal de Bruijn about 5 years ago

This seems to work in our 1.1.x tree, so I'm guessing this is a regression. Further investigation needed.

#2 Updated by Berthold Crysmann about 5 years ago

Dear all,

I can confirm this bug for Nikon 1 J1. Exiv2 lists my lenses correctly, yet in darktable the lens field is empty.
It seems quite important to get this right, since lens correction needs to know for 30mm focal length whether the picture was taken with the 10-30mm or the 30-110mm lens.

Just in case, I attach two .NEF files, one for each lens.

Cheers,

Berthold
