Just take over the settings in red and your have it, the other option are not critical.

You can set optimized on just like I've, it makes a smaller file but a few programs don't like that but I never found it a problem.

Just forget about ppi as you can see you don't have that option here, it only makes things more complicated then it should.

Near the space where you can set the pixel you also see Bicubic Sharper They advice that for reduction, it makes your photo make crisps but it's not really needed but I also always have it on that.

Here you will find some answers.

It's an interesting camera that's for sure, I wonder how good the lenses are...

The EVF hasn't pulled me over, it's the lag that does it for me and they seems not so good at low light as well, haven't tried it there.

I'll probably try to buy pentaprism as long as I can.

Ah yes but I don't think the biggest market for the camera is going to bother with manual focus to be honest.

Netbook might do but I don't know if the screen on those are good enough to really judge a photo correctly on them.

The ASUS Eee PC 1101HA has a fairly large screen for a netbook with a high resolution for it.
11.6 inch across 1366 x 768 pixels, so that's quite good and the battery life is up to 11 hours so more then enough.

No scrw-drive in the body so SDM only then.

From the news that was on the net this is all samsung, they are trying to do it on there own without copying pentax, that's why we didn't see a samsung version of the K7 most likely.

Also now that the KX has a Sony sensor it seems Samsung and Pentax aren't so good friends any more.

This is me though but the camera wouldn't be a Pentax for me without a pentamirror or pentaprism

Also with the 645D coming next year were they need to build a new lens line up I don't think they have the time/resources to also build up a line for a micro format.

Some updates for the Metz flashes.

I've never been so fond on acer, one had the DVD writer connected a bit strange so it could only write at 1X speed and the other the screen died.
Asus seems to be a good, they used to build the apple macbooks and have worked on them, thosiba was very good but they are a bit less now from what I heard, but my grandpa has one which is still going strong after 3 years.
My step-mother has a HP and my mother as well and they work good as well.

Maybe this one:
Asus K50C-SX002A
Intel Celeron C220
Intel Mobile Chipset
2GB DDR2-800MHz
250 Gigabyte Harddisk 5400rpm SATA
DVD-Rewriter Dual Layer
Intel GMA4500m
15,6" TFT Display Wide LED Shine Display 1366x768

€ 399,- is the price so that would be around £350
RAM is very easily upgraded for £30 you can add 2gb more.

The battery will last for 1.5 to 2 hours with this one.

Wow Hefty nailed it perfectly, great comment

There is btw a special blending mode in Photoshop extended that does what you want.
