"Defishing"
As mentioned above it is possible to "reverse" the fisheye effect with the help of tools
such as PT lens. It is not a lossless procedure - you abandon some of the outer
image portions due to image cropping and the "pixel stretching" produces quite a bit of softness
in the image corners.
Here's a sample image kindly provided by Ruediger Neumann:

As a referece here're also two "defished" sample shots from the previous section.

Verdict
Fisheye lenses are never really perfect performers. However, these are special effect
lenses where sheer quality is more a secondary aspect anyway. The
Pentax SMC DA 10-17mm f/3.5-4.5 ED[IF] Fisheye is certainly sharp enough for its
purpose and the high degree of barrel distortion is naturally a feature to enjoy and not
a bug. However, the Pentax lens clearly has some downsides. The bokeh (out-of-focus blur) is very
harsh - see e.g. the "horse" sample image above. A real problem of the lens are lateral
chromatic aberrations (color shadows) and, more so, purple fringing (color blooming).
Lateral CAs can be reduced but this is barely possible with PF. Normally I'd say that
the degree of PF is a show-stopper but a fisheye isn't a normal lens anyway. Compared
to similar products such as the Nikkor AF 10.5mm f/2.8 DX or Olympus Digital Zuiko 8mm f/3.5
the price of the Pentax lens is very attractive at around 550€/US$. However, if you're
split between a fisheye and a corrected ultra-wide lens you should probably still prefer
the latter - fisheye lenses are really specialty items. That all said, it is lots of fun to
go out there and play with the Pentax SMC DA 10-17mm f/3.5-4.5 ED[IF] Fisheye ...
