Thanks to everybody who responded to my question.
I am still open to further comments,
but I particularly interested to hear people's opinion about:
What would be reasonable prices that one can find for any of these lenses
used, in good condition?
Also, can anybody comment on
A 135/2.8
Igor, the F and FA Versions are by far better. The A is the worst of
all 2.8 (2.5) Pentax 135mm.
Best regards, Hans.

You can find discussions culled from the PDML of most Pentax Lenses here:

not that we don't like answering questions but it may save you some time.

I have the FA135/2.8 IF. It's a fine performer. I don't see any of
the purple fringing that someone mentioned with the DS.
My other 135 is a Takumar (K-bayonet) 135/2.5, which isn't comparable
at all unless stopped down to at least f/11.

Great!
Thank you, Peter (did I get it right from P. J. ? :-) ) and Kostas!
Those links are indeed very helpful!
Again, many thanks to all who responded.
Igor
PS. As you might have guessed, I am considering some enablement :-)
So, if you are considering selling any of Pentax SMC f/fa/d-fa
I have the F 100/2.8 macro and use it frequently on the ist-D. No
complaints whatsoever. It's very sharp.

even with superb design, it doesn't go away completely.

Any comments on comparative optical (and otherwise) quality of them?

I decided against the FA 135 for digital because I saw some severe
purple fringing in the center of images at f2.8 and f4.0. The FA and F
are supposed to be the same, but in

purple fringing is a sensor problem on a DSLR, seldom a lens one.

D-FA 100mm f/2.8 Macro: Optimized for digital. Presumably less
suceptible to purple fringing and the like than the FA version, though
I've heard very few complaints about the FA.
