Re: 100/4 Macro?

I think they are kind of rare. I have no specific information. 
Generally, SMC Pentax (K) lenses are considered to be slightly better 
than the smaller SMC Pentax M lenses model for model as they were 
suposedly optimised for performance while the M lenses were optimised 
for size.

Anyone know if this is the same optically as the SMC-M 100/4 macro?
Can't find this one mentioned anywhere.

I believe that since 1964, with the 4/100mm Bellows Takumar (not SMC), 
until 1989 with SMC A 4/100mm, all lenses use the same optical formula: 
5 lenses in 3 groups.
