I would have rather had a camera which produced sharp images and if you wanted softer ones you would then tweak the sharpness down. I think it is far easier to soften up a sharp image than sharpen up a soft image. All in all the image with the K20D is very satisfactory. I love supersharp pictures though.
But I am seriously considering changing to a Canon. Ohh but the costs of changing. Especially now that the value of DSLR's without video are dropping very fast.
With all respect, you need to learn a bit about how sensors and the eye work and realise that artificial sharpening added after the fact is just that... a trick to increase local contrast and fool the eye into seeing edge detail. I prefer a camera that does no such thing without me telling it to.I was a bit disappointed with the sharpness of the K20D.

True sharpness is down to:
a) holding the camera steady
b) holding the subject steady
c) having enough depth of field to cover the zone you want in focus
d) having a fast enough shutter speed
e) having a sharp enough lens
It has nothing to do with Canon versus Pentax. If you cannot get a sharp image with the K20D you cannot get a sharp image with any camera and it is not the tool you should be blaming.

"Many digital photographers do over-sharpen their images"
Agree 100%, in fact I think the majority of digital users over-sharpen. There seems to be a massive interest in sharpness and little in other image aspects; is colour fidelity not important? or contrast? or EV range? etc etc.
At the NEC show earlier this year on the RPS stand there was a display of shots from a member showing his ARPS (I believe) panel of the entry...the shots were all horribly over sharpened, they were terrible.

I had problems with some older Sigma lenses and the autofocus. Sharpness is very acceptable now after buying new pentax lenses. Havent yet tried to calibrate the autofocus, with the particular lense. I have got the focus card though. Probably sharpness is OK, or I would have taken the trouble to go further.

KR, Pentax 55-300 DAL, Pentax DA 17-55, Pentax 35-80, Generic grip, Generic remote, Nissin Flash. HISTORY - MZ 50, MZ 60, *istDS, KM, K20D, Nikon F60, Nikon F90. Large assortment of Point and shoot film and Digital, Sigma 70-300 APO DG, Samyang 500mm mirror lens, Sigma lenses of all assortments. K20D now sold. Sad to see it go, but makes room for an eventual upgrade to the K5 or the K4?

The enemies of sharpness are more likely to be down to lenses, camera shake or depth of field problems.
