Super Takumar vs. SMC Takumar

[Peter Spiro]

Today at a camera fair I passed up what might have been a good deal on a 
SuperTakumar 35mm f/3.5 lens.  I'm hoping to find the multi-coated version 
instead.   Does anybody have experience in using both kinds?  Is there a 
noticeable difference, e.g., in contrast, under ordinary shooting 
conditions?   (I've never actually used a Super Takumar lens, but I used to 
have some pre-multi-coated Olympus Zuiko lenses which I recall had quite low 
contrast, and this has prejudiced me against these older lenses.)
