I'm 23 if you want to know and I'm not the youngest on the forum... I don't remember who was though

About the tricky question, I ain't doing that bad right with not even 2 years of photography experience? I bought the K10D which is my first camera a few weeks before I joined the forum.

Thank you Peter, wouldn't have been here if it wasn't for all the forum members.

Thank you Peter, George isn't around very often any more and I'm trying to fill in that blanks with quantity because I can't match the quality of George comments yet.

I'm currently unemployed though and I already finished school beside my internship which I'm trying to find one. I've send a real letter to the states but it was just one day before the ash-cloud so with some luck they finally got my letter now or very soon, so cross your fingers for me please. I really want to go to that place and that's why I hang a bit back contacting others.

The past few weeks I've been searching the web for internships, being to Antwerp taking photos, took photos on a my little brothers party (might upload some photos), fell in love with my first ex , playing with pre-release of a certain photography program , watch the BBC series the genius of photography, watched Edward Burtynsky's Manufactured Landscapes (very good you should see it, maybe I can broadcast it over the web?) and have copies of Annie Leibovitz Life Through A Lens, Edward Quin Riveriera Cocktail & Henri Cartier-Bresson The Impassioned Eye which i still need to see, bought a cuddle today and a monday or tuesday I've a shoot with my two smaller cousins (5 months and 2 years) as subjects and on the other day I will go to the photo-club and help some school kids in the darkroom for the first time which will be fun.

You see I've been busy
Oh and just in mysteries way my Spyder3pro transformed into an elite so I can now calibrate the projector at the photo-club

ATI has some very nice features now for multi display. The new cards mostly support 3 screens out of the box but there are special version that support 6 screens at once.

And the Pentax DA 18-250 was a rebadge Tamron one so they are hard to get new also.

With the K7 you can use optical preview, it close the aperture and you can actually show the effect it has, you can easily place your DOF that way then.

Of course the scale works, nothing about the lens change the only thing that effects the depth of field of the scale is the Circle Of Confusion but that doesn't have a large enough impact on the scale to make it useless, it's still a good indication although not perfect.

Just to make sure, the Crop factor can not and does not change anything to the lens physhically so 50mm stays 50mm regardless the sensor size.

Also modern lenses have a DOF scale it's just that zoom lenses don't have one, there are actually only a few zoom lenses that have so that's normal, nothing has changed
I've no idea where it came from that older lenses always have a DOF scale because it simply isn't true.
here take a look, only some zoom of the A series have a DOF scale http://www.pentaxforums.com/lensreviews/index.php

Edit: here is something to make your own chart if you want http://www.dofmaster.com/charts.html

Yeah you need some special software for that i believe... don't know if they provide that.
I know that with the Spyder3Pro you can do multiple screens don't know if there are any Huey products but i'm sure there are.

This site has some very good reviews btw. http://www.northlight-images.co.uk/

Tom, I recently bought the 3 version of that and I'm quite pleased so far. The screen looks a bit duller now and some colours looks different and I thought I had it quite well calibrated by eye but guess not.

For less then 100 pound you can get a calibration device so there is little reason not to buy one if you do photography.

Great photos Andrew, I'm glad your back and I hope you didn't mind the few extra days.

I really like the one in the middle with the waves and the two that follow, the colours are just so vibrant of those.
The only photo that I don't really like is the last one, it looks oversharped to my eyes.

Depends on what you want to do with the lens, for landscapes the sigma would be fine but with buildings and interior shots I would rather have the DA12-24 because it has less distortions.
Although CS5 has an auto correction for sigma lenses but it doesn't include Pentax yet...
