The sharpest lens I own is the Vivitar 90-180m f4.5 flat field. That's
just purely subjective, no actual testing. It is however not
particularly convenient being heavy, relatively slow, and requiring the
green button kludge to meter properly. Of my Pentax lenses, the 43mm
limited is best stopped down just a bit, the SMCP [K] 135mm f2.5 is very
sharp wide open, and the SMCP-F 70-210mm gets lots of complements on
it's sharpness.

yet there is little that exceeds sharpness as the mark of a great
optical design.
There have been several lenses that have been claimed to be the
"sharpest" in the Pentax stable, and others beyond Pentax (Zeiss
probably most often mentioned).
So I thought I would ask PDML members for their opinions on which lens
(or lenses) they would rank as the sharpest in their stable:
Overall
and
Wide Open
I do not have a GREAT collection of lenses from which to choose, but I
would have to say that mine right now, at least the sharpest wide open
is the Tele-Takumar 200mm f5.6. In addition to sharpness it has great
color and contrast. I love that lens. I have two lenses on the way
that might rival it (we'll have to see)... a Vivitar Series 1 28-90mm
f2.8-3.5 and a screwmount S-M-C Takumar 135mm f2.5 (version 2). The
latter is definitely not the sharpest wide open (but acceptably so)
but is often mentioned as one of the finest 135mm lenses in the known
universe.
What say you?
