The 50mm f1.7 has the flattest field of focus of all the non macro
50-55mm lenses Pentax made, up to the DA series lenses, for those I
cannot vouch. It's the recommended lens to be used with the Autobellows
for that reason, (if you're not using the actual Bellows lens that is...

A 2006 comment from a recently-departed list member:
"All the Pentax 50mm lenses in the f/1.4 to f/2 range are good lenses
(perhaps the K55mm f/1.8 is the exception, it isn't all that
wonderful until well stopped down).
Of all the ones I have, I think the K 50mm f/1.4 is the "sharpest",
the M 50mm f/1.4 is the "creamiest" (for lack of a better term), the
FA 50mm f/1.4 seems most excellent, but I haven't shot a lot with it
yet, and the 1.7s and f/2s in whatever series all seem very good as
well."
This is a good summary of everything I have read and seen on this topic. In
short, the Pentax 50mm lenses (as with most if not all manufacturers) are all
good quality lenses with only the subtlest of differences among them.
I would trade an M series for an A series in order to get the extra
functionality on more modern cameras. I would trade a 1.7 for a 1.4, or a 2.0
for a 1.7, to get the extra speed. But the image quality is just not a factor
when considering which lens or lenses you should own in this class of lenses -
they are all good.

I've been relying on Stan Halpin's website to a large degree in deciding which
lenses to buy. I've got an M 50mm/f1.7. There's an A 50mm/f1.7 on a black MX
that I've been looking at.
While that lens is listed on Stan's site, there is no information on it. Any
opinions about it -- image quality-wise?
