I skipped the K10D, when it came out. The K100D used pretty much same,
though improved, probably in manufacturing, guts as the *ist Ds series,
if you compare the specifications they were damned near identical.
The K10D had roughly 60% more MP than the*ist-Ds but linear resolution
was only a tad over 30% higher, so really not that much extra cropping
room to get a 250 dpi 8x10 which was my criteria for not jumping on the
K10D band wagon.
I remember downloading sample raw files and comparing quality to the
*ist D and Ds that I owned. Image quality was about the same but with
marginally higher resolution. Printed un-cropped 8x10s the quality was
indistinguishable. If you insisted on making the largest print you
could with either sensor, you could make a ~13 x 8 1/2 inch print with
the 10 vs ~10 x 6 2/3 inch print at 300 dpi, but an 8x10 print at ~250
dpi for the *ist-D or Ds was pretty much equal quality to 300dpi at
normal viewing distances and for the web they were all overkill.
Image quality between the K20D and the *Ist D/Ds, which is for all
intents and purposes the same as the K100D, this I can make some actual
personal, comparisons.
The resolution of the K20D allowed a 50% larger print at any given DPI,
and I needed higher resolution than the *ist cameras for a paid gig,
which I thought might lead to a lot more work in the future...
Well enough about that.
So to reiterate, the resolution is considerably higher, enough so that I
thought it was well worth getting a K20D. I would have bought one anyway.
Good, /well/ /exposed/ images from the K20D (Samsung sensor), are just
as nice as the lower resolution Sony 6mp sensor in the *ist-D/Ds. So
I'd say the K10D sensor is probably on a par with the K20D sensor for IQ
if you get everything right in the camera with the K20D, and with the
K20D you get to crop more, or make much bigger prints at equal dpi.
However, the smaller resolution Sony sensor produces files that can
stand a lot more manipulation before they begin to fall apart. For
example the 6mp files are much easier to recover from underexposure.
The K20D files are prone to some really ugly artifacts and banding,
(which you can sometimes see in shadows even in well exposed images).
I don't know if the K10D files are prone to the same problems,
personally, but from all accounts they are much more forgiving than the
K20D files, more like the 6mp files in that regard.
Finally you can compare the scores at DxO Mark for the K20D and K10D,
(the K100D apparently wasn't tested by them, none of the 6mp sensor
Pentax cameras were). There is a 1 point difference in overall sensor
score between the K10D and K20D with most of the raw data favoring the
K10D.
Then there are the non image quality related differences between the
K20D and K10D, (and K100D), the K10D is a huge step above the K100D in
buffer size. I believe it's rated as unlimited up to filling the card
with full resolution jpegs at high (3fps, seems slow now, but it's a bit
faster than the K20D and K100D at 2.8 fps) fps.
For some reason the RAW buffer is smaller than the K20D, 9 vs 14.
Personally I never remember the buffer on the K20D or even the, *ist-Ds
limited as it is, as being a huge handicap, but the K10D is a big
improvement over the K100D and a bit better than the K20D for Jpegs at
least.
The controls are pretty much exactly the same and same locations as the
K20D, which makes it a pain transitioning between the K20D and the K5II,
(and I expect the K3 or K1), or the *istDs, (which aside from the tiny
review screen is pretty close to the K100D and actually more like the
K5II than the K10/20D).
Now considering the image quality and other tangible qualities of the
K10D, would I want one, well it's ergonomically pretty much a K20D with
slightly better image quality with slightly lower resolution. I still
use my K20D even though the SD card door is broken and the OVF has a
cracked rear element, it's not worth enough to sell and not economically
repairable, (cursing it's differences from the K-5II every damn time I
press an incorrect button).
I expect that Ken takes a lot better care of his equipment than I do mine.

How does the image quality compare to the k100 and the k20?

Looking to sell a very slightly used K10D body. Has 2590 shutter

Complete with original box and all items originally contained in the
box,
including battery.
Absolutely no wear visible.
I bought this K10D late in its product cycle, a few months before the
K20D
was available. I immediately bought a K20D and treated the K10D
as my backup which I never used. Its been sitting covered on a shelf
all
these years.
If it were listed by KEH it would be a LN - 99% of new, including box
and
instructions.
