The Takumar 105mm f/2.8 exists both in Super and in Super-Multi-Coated designation, but apparently both have the same optical formula. In my experience, it's not a bad lens, but it is a whee bit to soft for me wide open.
Aperture range: f/2.8-f/22
Minimum distance focussing: 120cm
Aperture blades: 6
I use the following dedicated ARG-file with exiftool: stak105f28.txt
-EXIF:LensModel=Super-Takumar 105mm f/2.8 (M42)
This works with LR4 and NEX-5 RAW-files.
