Are you sure you are using a RAW (CR2) image to test?
Most profiles don't work with jpg's.
That is correct and yes I am using RAW images. As I said, the process works fine when I start a new catalog, just not with my existing one
That short list of lens manufacturers is for JPGs or other non-raw files.
Please show us a screenshot that shows the current photo's filename and extension along with the short list of lenses.
Hey Guys, So I'm feeling pretty silly right now!!
Turns out my system has never uninstalled my version of Lr5.7 and I opened that one instead
When I open it in a new catalog I also opened LR 2015.6.1 and that worked, obviously!!
I've now uninstalled the duplicate and old version and reimported into my normal catalog.
Thanks for the inputs though
Happy it works now
Full new versions are never uninstalled, i.e. 5.x is left in-place when 6.x is installed and the catalog is copied and the copy is upgraded.
"Point-upgrades", i.e. 6.x -> 6.y always completely replace.
Thanks, I had never realised that
Running LR 5 vs LR 6 is a reason to have a slightly different list of lenses as LR 5 won't have the newest lens updates, but the very short list of lens manufacturers shown in the screenshot of the first message is due to the selected image being a non-raw--a JPG, TIF or PSD, not the difference between LR 5 vs LR 6.
