What version of photoshop and camera raw do you have?
I found these camera raw files taken with a canon and that lens and camera raw seems to detect the right lens automatically.
(couldn't seem to find any nikon raws taken with that lens)
Sample file from here:
You could download one of the above raw files and see how it works in your camera raw.
Photoshop CC 2017.1.1 Camera Raw 9.12 macOS Sierra 10.12.6
Thanks for the reply. I am using Camera RAW 9.12 itself. I downloaded the images from the link and they are recognized correctly.
What I have done at the moment is manually choose the right lens and have saved it. So now when I open a pic (Nikon mount) and choose auto detect, it is being recognized correctly
Will this cause any difference to the image? Is it possible that the lens has some issues? :/
This problem is still occurring.
