Description

The "Sigma 18-250mm 1:3.5-6-3 DC OS HSM" lens for my Pentax is not recognised properly by exiv2 v0.23. It seems Exiftool does recognise it:

../Image-ExifTool-9.02/exiftool ./IMGP3550.DNG | grep -i lens
Lens Type : Sigma 18-250mm F3.5-6.3 DC OS HSM
Lens F Stops : 5
Lens ID : Sigma 18-250mm F3.5-6.3 DC OS HSM

but exiv2 doesn't:

exiv2 -pt IMGP3550.JPG | grep -i lens
Exif.Pentax.LensType Byte 4 Unknown (0x0808)
Exif.Pentax.LensInfo Undefined 67 168 48 0 8 114 40 86 42 157 96 1 12 109 193 171 132 28 1 82 108 251 255 255 255 255 41 96 1 12 0 170 10 97 0 0 0 0 175 238 8 240 0 0 159 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0

A sample image is attached. (Also posted in the forums some time ago but this seems a more appropriate place)
