The two lenses are supposedly identical in regard to optics, although the M42 has a larger filter ring. In any case, the K is at least the equal of the screwmount. They turn up on ebay from time to time for $350 to $400.

I would LOVE to have a K85/1.8!  Anyone know where I
can find one???  I assume it is as good as the M42
versions?  I was thinking of getting the M42 version
and then an adaptor to mount it to the istD.  Finding
a K mount version would be better, assuming it is as
good as the screw mount.  What are the opinions of the
K Vs. the M42 85/1.8 lens?

I have an A50/1.7. I find it to be an excellent
lens, sharp and with high
contrast. Though I used it quite a bit in the past,
it now resides on a back
shelf in the equipment closet in a sealed Glad bag
with a little packet of
silica gel. Of the 50's, I use the A50/1.4 almost
exclusively, not that it's
better. In fact I think the A50/1.7 is just as good
and lighter. It's just
that it's what I use of the 50's. Occasionally I
throw on the A50/1.2 just
because it's big glass, but it's not near as good as
the A50/1.4 or A50/1.7.
I strongly dislike the A50/2, I think it's crap.
Perhaps I just have a bad
sample - misfortunes of mass production. The lens
most commonly found on my
camera is actually the K85/1.8. If you don't have
one, you need to get one.

While I like my lenses (otherwise I wouldn't have
them), and
especially like the 1.7 for its size and light
weight, it doesn't,
to my eye, have any particularly outstanding
optical
characteristics.

Yes, Shel, I personally would agree. However, I
was just hoping to
get some of the "as-yet-unheard-from" 50/1.7 fans
involved in the
discussion. After all, a thread on "Pentax's Best
50mm Lens" would
theoretically be relevant to almost any PDML
member - <g>.
