You want the 80/1.9 lens, not the 80/2.8 lens. A very special 80mm for sure.
I'll agree with this despite the 80 f2.8 being VERY very good.
I have both and if I'm shooting people, and wide open or close it's the manual 80 1.9 otherwise I use the 80 2.8 if I know I don't need the bowkahmachine. (there, technically I didn't say that dreaded word…exactly )
