Sometimes there is a problem reading the EXIF data in the image file.
The attempt is only made for raw files, not JPG and TIF.
There could also be a confusion on which lens the EXIF data is referencing if Canon and a third party use the same lens codes.
Thanks for response. Of cours, I am talking about RAW only. The metioned problem concerns Canon 5D Mark III and Canon 100-400mm 4.5-5.6 II lens. Can I report it to Adobe for advice? If yes, how to do it?
I have forgotten to outline that in LIBRARY section the lens is recognized properly. The problem concerns only DEVELOP section where the lens remains unrecognized.
