experience with the K-x, its younger brother. The guy who sold me
my K-x had bought the K-7, which is certainly more rugged. Its only
disadvantage was that the K-7 does not have quite such good low-
noise performance. The K-x is excellent in this respect.
On thing you will like is the logical and easily understood set of
menus and controls. I had to spend a couple of days studying the
manual of my D300 before I could get the hang of it, and set up
the defaults I was happy with. The K-x (and I assume the K-7) has
never needed me to RTFM.
If you use a simple M42 to K adaptor, you can use a Peleng 8mm fisheye,
which will give you an almost full-frame image (slight cut-off in the
corners) and allow you to take 360 x 180 panoramers with four shots
at 90 degrees (easy to do by eye on a monopod). If you use a ring
mount and tilt the camera until the diagonal of the sensor is vertical,
I believe you can get away with three shots, although if people or
things are moving around you won't have enough overlap to deal with
seam problems. Or, since Pelengs are getting arther expensive these
days, you might prefer to get a Samyang 8mm, although it will not be
possible to make three-shot panoramas because of the lower
effective FOV. Mind you, the Peleng has its own problems, so I'm
not giving it an unqualified recommendation, just saying I am happy
with it myself.
But one of the nicest things about the K-7/K-x is that you can get
the Pentax version of the Tokina 10-17mm zoom fisheye. This is one
of the best zoom lenses available for VR/panos. You will need to
shoot six around, plus zenith and/or nadir shots.
You will need to run your four/six/eight shots through a program
that can remove chromatic aberrations. But that's not a problem of
Pentax camera/lens combinations alone.
The K-r has just come out in Japan. Maybe you should consider that,
