Hello All,
Just obtained the subject lens, and tried to find the lens ID code for it.
Using exiftool, as follows...
[terry@localhost 18-300-sigma]$ exiftool IMGP0382.JPG | grep -i Lens
Lens Type : Unknown (8 34)
Lens F Stops : 8.5
Lens ID : Unknown (8 34)

I interpreted this code as 0x8034, and added this code for the lens to my local source and built, but using exiv2 as follows...
exiv2 -pt IMGP0382.JPG | grep Lens finds nothing.
Have I misinterpreted the code as given by exiftool, or is there likely to be some other problem here?

Hi Terence

Would it be possible for you to provide a test file and give us permission to use the data from that file in our test suite?


Updated by Terence Duell about 6 years ago

Hello Alan,
Yes. I have attached a reduced quality copy of the image I used. It seems to have the exif data, but if you have problems please let me know and I'll have another try.
