There are also some other options.
Photoshop elements 7 for example support the newest version of adobe camera raw and comes at a better price (i believe), adobe lightroom 2 is also pleasant to use and you should be able to combine that with the photoshop you've now.
You can download the full version for a trial of 40days at Adobe so give it a go.

Most memebers here are in love with silkypix, you can't be as creative as in photoshop with layers and things like that but for normall photo editing it's more then enough.

Wow they are so sharp and with a good DOF as well, splendid!

Mike and Amin, what about using a monopod instead of a tripod?

We already had that discusion here on the forum 3 days ago.
The thing is that DNG that the camera make is hardly compressed, you can make twice as much photos with PEF and if you use the computer to convert them once again you end up with a small file.

These are some numbers with the K10D, all the same photo.
PEF = 8,15 MB
DNG = 16,1 MB

Converted with Adobe Lightroom 2.2
PEF > DNG = 6,94 MB
DNG > DNG = 7,14 MB

you see the benefits of shooting in PEF and you convert them in to DNG on the pc, that way you're quite sure you can open them over 10 years.

It's too outdated (March 2002) but here are all the downloads link
Adobe Camera Raw 3.7 and up have the support for the K10D so you need atleast Photoshop CS2

This a DNG converter, it will convert PEF to DNG. link
DNG is also a camera RAW but because the computer compress them it's smaller and more program support it.
Here is some more data what software support it link

More then this I can't help you, photoshop 7 is just too outdated

Sorry Vikram, photoshop 7 is something completely differend then photoshop elements 7, he can't use it.

Adobe Camera Raw 3.7 is the ealiest version that support the pentax K10D but that one can't be installed on photoshop 7, it doesn't even support DNG.

Here's a test on tom's hardware link

They also had a problem that the cardreader wasn't fast enough with most class 6 cards

There is a coating over the sensor so what you actually clean is that, it can take some punishment I guess.

Since I use an articbutterfly I must say that i clean less often, once in the 2 or 3 months now, used to did it monthly with a blower.
The problem was that you just move the dust with that thing but it keeps mostly in the camera so over some time you can clean it again. The butterfly collects (more or less) so you basicly remove it out of the camera.

there are also other tools that removes it I believe, swaps for example.

Do you've adjusted the diopter correctly?
point the camera at a blank wall and adjust the diopter till you can read the the information/camera settings clearly.
