Thanks, Rob. I'm looking to use this on a full frame body - *ist, Mz-S
or LX - with film, of course. The 17 to 50 would be too short. I should
note that an aperture ring is highly desireable as well, as it would
allow for the LX and other older bodies. (Event he Mz-S is somewhat
limited without an aperture ring.)

I have the Sigma Lens 17-50mm f/2.8 EX DC OS HSM, it's pretty good but
maybe a bit too short on the long end for you, are you looking to
shoot on FF or a cropped body so are you lokking at an equivalent FOV?

I've been shooting a bit of film latelyand have been using the FA 28-105
f4-5.6 zoom as my everyday lens. This past week I was really chaffing under
this lens - it was just too slow, the rotating front element was at times a
PITA, it is heavy (thanks to the power zoom motor etc), and looking at the
image results, it is rather soft around the edges when shot wide open (which
I do more often that I'd like because it is so slow!) Granted, I was
shooting IR film and using a #29 deep red filter most of the time (-3 stops)
but this made me wonder about alternatives....
Looking at Pentax Forums lens ratings, I was surprised to see that the two
zooms I have (the 28-105 and the FA 28-70 f4 AL) are near the top of the
pack for the "consumer" zooms and altually very close to the the FA* 28-70
f2.8... I would rate the lenses I have as very good in terms of optical
quality, but falling short of really first rate quality.
Can anyone suggest any top-quality 3rd party lenses in the 28 - 100 range
that I should take a look at? I am hoping for somehitng that is faster than
what I have (either f4 constant or f.35-f4.5), 24/28 mm - 90/100 mm,
non-rotating front element of very good optical quality (on par with the
lenses I have.)
I won't go on from there ...
Any suggestions?
