I'm not sure the guys fixed it all properly... It's showing significant noise from ISO 400 and up.
More than I'm used too at 200 as well.
Did any of the firmware updates alter the amount of noise at relative ISO's??

Andrew,
No, the firmware upgrades do not influence image noise as far as I know.
There are 2 types of noise in these cameras: 1) sensor noise and 2) cross talk.
The first is mostly temperature and silicon/chip design related, the first has to do with how the high frequency electronics in the camera is shielded.
Cross talk noise typically shows up in vertical bands in the K10D and there have people with K10D samples that had a particulary problem with cross talk. Since this is a hardware related issue, the only solution is getting the camera changed.
The sensor noise can be more or less depending upon the specific K10D item, but is unlikely to differ a lot between cameras. Sensor noise does not show any particular pattern.
If you are shooting jpeg, maybe someone turned off the noise reduction in the customs settings.
However, personally, I would always shoot RAW for a wedding session.
There is some good noise reduction software available, search this forum for references.
The best thing to do in a wedding shoot, is to overexpose a little (1/3, 1/2 up to 1 stop) in darker situations and correct that in post processing.
You will avoid noise that way, since noise in more visible in darker areas (less signal to noise ratio there).
Has this been to technical? I hope not.
