First time i hear about a White Balance Lens Hood you've a link?

This might also be a solution if you shoot RAW, a bit more expensive but it also correct/calibrate your colours.

I have often wondered, however, how you know what lenses it actually corrects, and if it is likely to ever get confused by a third-party lens and alter the image? Is there a list of supported lenses for this feature?
Third party aren't support because they reverse engineer the lens so it only work on Pentax.
I believe only the DA, DFA and the FA limited lenses so out of my head.

What about a Pentax 6x7D, they should throw some eyes open with that one.

The Chrome OS notebook seem to be very secure.
The pwo2own hackers haven't be able to crack it.

LV was spot on but when shooting through the view finder it was FF. So I make an AF adjustment on the lens of -8 and through the lens now is nearly spot on but then surely that would then kick the LV out? or doesn't the LV apply the AF adjustment? It doesn't appear so as now both are spot on....
LV use a very differnt system so the AF adjustment have no effect.

Liveview looks at the picture and try to create the sharpest contrast, if you've a sharp contrast it's sharp. As far as i know the af adjustment doesn't make it look for a weaker contrast.

The Phase AF system is very different and you also have the problem of small variation in the calibration and aligment of the AF sensor and the lens AF.

Here you can read more about it and below that is contrast AF.

It might sound strange but how does it preform with a slower lens?

With most laptops the ram is easy accessible by removing one screw, so most of the time it's not a big deal.

There is a way of getting Vista to use a USB stick as memory for small files, but it only shows an improvement in speed with 512K of memory.
I forgot the name of that but Win 7 has that as well but it's not really for files it's there to help start up programs faster.
Ready boost, that's the name.
You can also use fast SD card if you've a SD reader.
