No the only solution is to install older firmware which doesn't support SDM. I'm not sat with my camera at the mo, but isn't there a 'enable SDM' setting on the K10 at least that could be switched off, thus allowing the screw drive to run? :
Also Pentax will drop the KAF2 mount for future lenses to save cost and weight.

The only good way to check exposure is to use the histogram.
Here is explanation about it: link link
Here is also a link about metering if you want to know more about it: link
What I now do is using manual mode with spot metering, when you press the green button it meters and set the correct value.
Depending on the program mode it will act differently, i've set it like AV mode so one press on the button and it set the right shutterspeed for the exposure.
It take some practice to know what you need to take a metering from but it works very well, certainly when you don't have changing light condition.

That’s a pity – I was hoping to get one for my DA* 300mm. I have just looked at the March 2009 roadmap and they have both gone.They have been postponed, perhaps indefinitely, I believe. The planned T/C has been taken off the road-map.

The K7 is out now but no news, maybe after the 645D?

It's correct what you said, you will see the point on the EV meter move if you do that.
In the custom menu you can also remap your E-dials for those modes.
I don't know the combinations out of my head but you can map "Exposure compensation" directly under a E-dial of your choice.

To late John did it last night.
Will test it later tonight I'm not even home right now

My concern is noise with those long exposures, CCD don't like to be turn on for long CMOS are better for that.
A dark frame extraction would remove most if not all of the noise though but that would take another 300 seconds or so

What gear did you use for that shot Martin, a remote with a Bulb lock?
You also have digital remotes which you can program.
I was thinking of getting one of those and set it to make 10 shots of 30 seconds with an interval of 1 second with the hope that's enough to cool the sensor down.

If you use the IR remote it will also switch off the SR, don't know if it does it with the cable release, does anybody knows that?

Good one Martin, if you use it on a tripod and with the same exposure constantly you only need to make one dark frame extraction.
So if you make 10 shots of 30 seconds you only need one dark frame extraction of 30 seconds for al those shots.
Simply put the lenscap on the lens and make a photo with the same settings.

But usually it's worth asking just why you need faster shutter speeds with flash (After all, several generations managed with even slower sync speeds ) Of course, there are perfectly valid reasons why you want fast sync speeds... but often it can be down to misunderstanding of what's needed for a particular setup.
