What a nice surprise! When using manual focus lenses with the S1Rii the focal length and the name of the lens are saved in the EXIF data. When using IBIS with a manual focus lens you can enter the focal length and you can create a lens entry with the name of the lens (which is stored for future use). The focal length and lens name are then saved in the EXIF file. This is very different than the S5, where you enter the focal length but no info is saved in the EXIF file. Is this new to the S1Rii, or was it introduced with the S5ii? In either event, it's a great addition for those of us who use MF lenses.
