Hello Joanna,
it’s the same in Windows. Searching for my 17-35/2.8 Lens doesn’t work. The search criteria 17-35mm also brings photos I have been taken with for example an Nikon Coolpix with 22mm focal length.
I couldn’t find any informations about search criterias like ‘17-35’ ore something else.
I asked for other search criterias in Search within Fotothek
Best regards
