By adding bellows or extension tubes you are making the camera/lens combination myopic (short sighted). As soon as you add any gap between the focal point of the lens and the film plane you won't be able to focus to infinity.

No - all the same (Firefox ). At home the image showed "Forbidden", but at work that link seems ok (although it didn't work the first time I accessed from work). As I mentioned above, the PBase direct linking specifies a different form to the URL than the one included by Liam.
I wonder if the actual image is served from a cluster of some kind that should be linked based on the image address, so for the above example the address should be:
http://www.pbase.com/mr__ist/image/71292888/large.jpg
But, as Liam demonstrated you can obtain the image's location by right clicking in the browser - and I suspect that address is temporary at best. (ie http://ct.pbase.com/g6/93/732293/2/71292888.Z2llf5cy.jpg )
Hope that makes sense!

It's only paying PBase customers, and the link isn't quite as you posted Liam, although that seems to work intermittently. I've added a space or two to demonstrate how you include the link, but so that it doesn't actually link to PBase directly and show the image as I'm not sure 100% about their policy.

Weird! It didn't include the image from home, but here at work, I see the inline image. Bizarre.
At least, that's what I thought PBase did... might check their T&Cs later.

You have to be a PBase support (ie pay money) to be able to link images inline, otherwise you just get a "Forbidden" message

You could do with an ND Graduated filter too - that would balance the sky exposure with the foreground. More playing....

Are you sure the gallery is publicly viewable?

* If you have a 12-24mm lens, then the Cokin P is too small You'll need a Lee system (I use a Lee Foundation kit plus Cokin Z-Pro ND grads)
* The Cokin filters suffer from a red or magenta cast, especially when you stack two or more together. The Z-Pros are much better than the A or P series, but Lee don't have any cast (but are lots of money )
* For polariser, you need circular if you want autofocus to work. I've used a Kood polariser in the P mount system and it's just fine.
As always, you get what you pay for, and I should've gone straight to the Lee/ZPro set and saved myself a hefty amount of money.
Also, get a decent case for the filters! They scratch too easily. Unfortunately for me, I have my Zpros in a Lee soft case, and one evening I put two filters in the one space and scratched them both
Hope that helps!

Probably the most wear for mine is on the K-mount - changing lenses in a hurry
In fact, AFAIK, all Pentax cameras have the ability to reset the image count back to zero after a card change In other words, you can't get a genuine, reliable, indicator of age and amount of use - perhaps only by examining the wear and tear.

And yes, I'd considered moving to the 5D as well... but I like the diminutive size and lens quality from the Pentax gear I have already, and the cost, weight and size of L series glass I can't justify (yet).
This topic has been discussed more times than I remember... and I think it's very unlikely to see a full frame 35mm DSLR from Pentax, at least in the near future (and perhaps never). Now half my current lenses are DA series that won't work on full frame anyway, and they give me more than enough wide angle to work with (with the DA12-24), plus resolution a plenty - I'm just waiting to see how these lenses perform on the K10D, and I don't think I'll be disappointed
If you really want full frame then there's only the 1Ds and 5D to choose from. But it's not such a simple question - if you check out the DPReview of the 5D you'll notice some downsides as well.
There are, as Gwyn mentions, advantages too - for wildlife and telephoto APS-C is just perfect.
As Will rightly says, the 645D should plug a hole in the resolution/sensor size gap.
And from what I've seen the K10D is lower noise than the *ist-D series. Can't wait to put it through its paces!
