No the Samsung sensor native iso is 200, that's why extended dynamic range limits you to that.

High ISO is better on the K7 but ISO200 is the native ISO of that sensor meaning that ISO100 on the K10D is better but up to iso400 there is little difference between them.

White-balance is better on the K7 and so is focusing, it also has an AF assist light to help in low light.

There are no such things as silly questions.

Simple answer is no, there is no such way.
The pop-up flash needs to trigger the Metz, you can set the pop-up flash probably on controller in a menu and it should contribute little to the photo... depending on camera settings and range of course.

There are of course way to trigger the metz without the pop-up flash but you need some extras.
You need something like an infra-red or radio trigger on the hot-shoe of the camera and a receiver on the flash, that way you can work wireless.

Lovely photos Prieni, like the others said the colour is superb.

F.8... he could probably have use the lens wide open, 5.8 isn't it?

Yes they could but they don't offer cashback on an lens or camera but on the total amount of pentax equipment purchased, so they need a receipt and the barcodes of the products to match them and the IBAN is there to minimize cost, since the money probably comes from a French bank account.

It's everywhere the same, not just pentax.
Btw IBAN number is quite standard now a days, at least here is.

That didn't work so well
You need to use the IMG code, the last one in the menu of photobucket.

David I'm not making it easy for you
The Tamron is so good as the same though with the Bokeh.
