yes thank you Terry, that was the word I just couldn't see it.

Terry I'm not the only one any more

Many of my age have a simple point and shoot camera but I never found them interesting enough so saved all the money for the *ist D at that time but at the time I had enough money I could buy a K10D.
This is still my only camera and I'm glad I learned photography on it.

From what I've seen I don't think I could get all out of a Canon at the time but never found them interesting, Nikon is another story.
It really was between the Nikon D80 and the Pentax K10D at the time, I knew that the *ist D was an amazing camera and I knew Pentax had some very nice prime lenses which is of course why you want a interchangeable lens system for right so went for Pentax in the end.

The ones before that where classed 20mb/s
There never was a class 10 officially in SD land, class 6 was the highest. But it seems they added a class 10 now.
http://en.wikipedia.org/wiki/Sd_card#SD_Speed_Class_Ratings

Every card that at least have minimum transfer rate of 6 MByte/s has already the highest class, class 6.
If you want you could call the older extreme III class 20 cards and the newer Class 30.

I believe a correction filter change the temperature of the sodium light to daylight so it won't block that colour but I can be wrong with that.

Well it has no use on digital because it always capture red, green & blue and the white balance simply change the balance between the three colours.
A correction filter will also shift the balance but since you can already do that it does not add any real value.
You might shift the colours so that the scene is spread over all the three the colours so that your sharpness improve but that's the only thing I can think of.

The tutorial you've there is the digital equivalent what such filter would do

It's not my photo but I got it from the Zandvoort circuit site and that's where I'm going.
It's most likely Zandvoort therefore, I don't know which corner though.

I'm going to meet another Dutch Pentaxian there so will link you to our photos on the Dutch forum when they are up.

That just comes down to the card, it just can't keep up with the constant speed that is needed to write the video.
The Panasonic SD-card also have this problem with the K7.

I said it's speed but it can also be the K7 that use a way to write data to the card which the card don't like, we will probably never know the cause.

Sandisk are proven to work perfectly and I believe Toshiba also but I don't know about the other cards, you can look at the Pentaxforums.com to see if they have more information.

Here is a topic link
Another one, this one is better link

Indeed Barrie, hopefully I get some good shots tomorrow.

John, Mike keeps saying he should sell his A* 300mm f2.8, with that he could easily funds the K7 so good thinking

What light did you use to lighten the photo up?
If you've a flash use that since those are daylight temperature, a tungsten light source would only make it more orange.

Thank you all

Yes that's correct you can fill card not larger then 4GB fully but you can only fill a 8GB card for the half because the the largest a file can be is 4GB on the standard format.
The file size limit is because of FAT32 like Pete says, exFAT has a file limit of 64 ZB (Zettabyte = 1 billion terabytes)

No Pete I don't wish that, exFAT really is the standard use for SDXC cards that will come this spring. link
SDXC is the card that comes after the SDHC in terms of size.
So it's like this:
SD = up to 2GB
SDHC = 4GB up to 32GB
SDXC = 64GB up to 2TB

Here are the SDXC standards on the official SD site link

Since the SDXC use a different file system exFAT as standard instead of FAT32 that means that a major upgrade is needed for cameras to support it also the only OS that support the format currently is Windows (XP, Vista & 7).
A solution is to format the SDXC card from exFAT to FAT32 but since the standard is exFAT that would probably mean that device that can't use exFAT can not be called SDXC compatible since it can't use the standard format (exFAT). I don't know how good that is for sales...
