Considering that the lens is an inexpensive consumer zoom and that the
picture is heavily cropped, I'd say the sharpness is surprisingly good.

Hi...
Get a look at the sky tonight, the Moon and Mars are very close. A
good opportunity for me to see what can be achieved from a *ist DS and
a SMCP-FA 80-320 4.5-5.6.

Shot at 320mm, ISO 200, f/8, 1/200s, spot metered on the moon itself,
on a tripod with 2s mirror pre-lift (no remote).
The infinite focus point is not actually at the end of the focusing
ring course, but a few degrees from it. So I "focus bracketed" (MF)
and chose the sharpest shot.
The picture is heavily cropped. One pixel on the web is one pixel on
the sensor (be sure to choose the 618x1017 version).
Post processing:
- PEF->DNG conversion
- Open in PS (no sharpening, 16 bit)
- Curves, sharpen, crop
Sharpness is somewhat disappointing. Anyone done something similar
with a good 300mm prime yet?
