Anyway, I am not really so disappointed in the K10D, but it was a lot of hype and added cost that could have gone to other R&D.

Seeing as I raised the question of Foveon sensors recently, I find this thread particularly interesting and wonder how well that type of sensor would handle this situation.
Perhaps the in-camera processing can be designed to recognise these symptoms and somehow compensate for them but if it really is a limitation of the Bayer-pattern system, then at least pro-spec. cameras should have something better.
the foveon system has certain advantages, but its low light performance is truely abysmal.

Is THIS what you mean George? I did what you said.
if you end up with a silly long url which is going to go off the end of the screen and cause scroll bar irritation you can also do this

just without the space at the begining, and this happens:

After all, we are about "all things Pentax" as someone mentioned earlier, and surely the photos we take with our Pentax gear are one of the most important "things Pentax"?
Photos for technical issues are a different matter altogether and should certainly be allowed wherever they are relavent, though personally I would like to see an 800x600 size limit, having to scroll to read the text puts me off reading a thread.

This effect is the reason why you should lock your focus when taking shots for a panorama, the difference in magnification can be a pain.

What I mean was that when you're focusing on something close you can see it getting larger & smaller in the viewfinder (for example if you changed from a focus point nearby to one far away) so it did appear as if the focal length changed as the various lens elements moved about. It wasn't a big problem in practice however.

If you really want to properly directly compare the output from these two cameras, here is what I would do
1. Buy yourself a Pentax Takumar 50mm prime in M42 mount, plus suitable adaptors to use it with both Pentax K and Canon EOS mounts. This way you can use the same lens on both bodies.
2. Set up a nice solid tripod in front of a sensible scene containing some fine detail, preferably under controled lighting conditions.
3. Set each camera in turn on the tripod and take the photo, checking histograms and focus etc to make sure you get the best possible picture out of each, and making sure you are focusing on the same spot with each.
You would then have two pictures which should in an ideal world be identical, and any differences will be a result of the camera body used since everything else was the same.

My K10D is set to shake itself on start-up. I've never had to do anything else with it.
I suspect that if you don't shake dust off immediately, it may form a stronger bond with the sensor surface, and then require more to dislodge it than a quick shake of the sensor.
So I shall stick with the shake on start-up.
