85mm f:1.9 S-M-C

Pentax M42 85mm f:1.9 Super-Multi-Coated lens..... Being a fairly rare lens, I was wondering if anyone here has experience enough with this version to be able to tell me how the IQ would compare to the Super 1.9 & the Super-Multi-Coated 1.8? Maybe this is splitting hairs a little too finely, but I'd like to know if anyone has an opinion and/or experience with this comparison? Where might the differences lie?

I have both the 85/1.9 SMC and the 85/1.8 SMC. No experience with the super-tak version of the f1.9.

The long story short:

f1.8 = sharper and better contrast wide open, some purple fringing
f1.9 = NO purple fringing and softer wide open.

The bokeh rendering is slightly different, as well.

See my comparison on Dyxum:
