</div>I just had a look a some pictures with exiftool: There I found some<br>
contradicting data:<br>
For the Tamron-17-50mm-zoom exiftools says:<br>
Lens Type : Canon EF 28-70mm f/2.8L or Sigma or Tamron Lens<br>
Long Focal : 17 mm<br>
Short Focal : 50 mm<br>
..<br>
Lens : 17.0 - 50.0 mm<br>
Lens ID : Tamron AF 17-50mm f/2.8 Di-II LD Aspherical<br>
<br>
digikam gives back: 161<br>
<br>
For the the Tamron-28-300mm-zoom exiftools says:<br>
Lens Type : Canon EF 28-200mm f/3.5-5.6 or Tamron Lens<br>
Long Focal : 28 mm<br>
Short Focal : 300 mm<br>
..<br>
Lens : 28.0 - 300.0 mm<br>
Lens ID : Tamron AF 28-300mm f/3.5-6.3 XR Di VC LD Aspherical [IF] Macro<br>
Model A20<br>
<br>
here digikam displays the correct lens: Tamron AF 28-300mm f/3.5-6.3 XR Di VC<br>
LD Aspherical [IF] Macro Model A20<br>
<br>
And last but not least exiftool identifies the Tokina lens as:<br>
Lens Type : Canon EF 20-35mm f/3.5-4.5 USM or Tamron<br>
Lens<br>
Long Focal : 24 mm<br>
Short Focal : 12 mm<br>
..<br>
Lens : 12.0 - 24.0 mm<br>
Lens ID : Unknown (160) 12-24mm<br>
<br>
in this case digikam tells me that I used a Canon EF 20-35mm.<br>
<br>
It seems to me that digikam is using different ways to handle the exif-data in<br>
order to determine the lens.<br>
<br>
Is there a way to persuade digikam to display the correct lens data?<br>
Thanks!<br>
