Given the state of Dutch photography magazines (rubbish! Sorry Golf) I have to say anything British or even American. I buy them when I get the chance, which isn't often as our local shops don't stock them so I get them mostly when I go to Schiphol or stock up on then when in the UK.
I am a subscriber to the Pentax User club magazine, which I enjoy also.

English is my mother tongue but Dutch is fast becoming my first language! I even dream in Dutch

As to spelling mistakes mine are due to my brain working faster than my fingers, and neither work very fast nowadays!

But that said some people do have a real problem with spelling - my son is dyslexic for instance, but I would hate to think he would be discouraged from contributing to a forum because of his spelling. He is understandable and that is what matters. Yes simple things like lense instead of lens are annoying to see but I really don't think it's worth getting your knickers in a twist over it.

I have a Pentax *ist Ds and on the course I'm following I have also used a couple of Canons, 350 and (I think) 300. Now my Pentax is so easy to use in comparison - so much more intuitive, you don't need a third hand to set things. Even the Canon users commented on that! I don't know what the K10D is like, sadly I can't afford one (yet), but if it is anything like my Ds it will be easy and intuitive to use.

I would suggest you go and get your hands on all the options in a shop where they will let you really try them out, read the handbooks and have a play with them.

Another advantage or two of the K10D are the weatherproffing, and the sensor cleaning as well as the anti-shake. The sensor cleaning I believe occurs at shut down unlike other cameras with it which do it on start up, which slows things down a bit.

If there is such a demand for FF cameras why do you see so few of them? Cost, size, plus the fact the people like the crop factor. Frankly I am bored to tears with this constant obsession for a Pentax FF.

I love my Ds, as you may have gathered. I like the size of it. The size (and weight!) of the K10D put me off it, as it does the K20D. I shall end up buying one though whether I want the bigger body or not. The Ds will not last forever, and i would like a couple of the goodies on offer on the newer models. And no the K200D is not really an option because of the viewfinder - though I may change my mind if I actually hold one - it actually gets better user reviews than the K20D. I would never buy a FF camera if it meant it was even bigger/heavier.
Now a Ds sized camera with the goodies in the K10/20D and I'd be at the front of the queue. It's never going to happen though, and I accept that.

Or Nottingham? Expand! Explain!

But thatserial number is the total number of photos taken. The file number of the photo for instance IMGP2156.JPG shows 2156 is the total number of photos taken. That is the only way to see how many have been taken with it - you will have to test a potential camera and when you review the photo in the lcd screen in the top right hand corner it will give the image number - that is the total number taken with it, unless the seller pressed reset. Or download the file and see the number on your computer. If the seller has pressed reset ask yourself why?

If you have it set correctly in the menu then it will give you the total number of photos made as your file name - it is set as standard to do that so it doesn't reset when you change cards. This assumes you had the camera new of course. Mine is at 3253 after about 18 months, but I haven't used it that much until recently.

If Scott Kelby's book for CS2 is as good as his one for PSE4 (and I can't believe it wouldn't be) then it is a must have book.

You are probably pretty close to the maximim weight your tripod and head can hold with that monster on your camera!
Look forward to seeing some photos with it.

Having used Canons on a course recently believe me I am so glad I have a Pentax (Ds). It is so much more intuitive to use, doesn't need a third hand to operate it which is somethiong I found I could have done with, I kept having to take my eye from the viewfinder to find the right button to press. And I wasn't the only one - even those who owned a Canon had trouble with it constantly for the same reason.

If you are considering the Canon 400, presumably for the megapixels, why not consider the Pentax K10D?

Nikon also has the Vibration Reduction on the lens, and has huge problems with producing enough of them. A friend of mine has been waiting a year for a lens!
