RAW files have never been totally 100% RAW as a certain amount of processing is needed to make sense of the Bayer grid info and merge it into a full colour image at every pixel site.
point of pedantry, that is actually handled by the raw converter, some converters give you a choice of algorithms for de-mosaicing, with some being better than others for high ISO or fine detail rendering.

You are correct that some processing is necessary though, the signal from the sensor itself is analogue (a voltage) and must be converted by the A/D converter.

I reckon you would still shave the best part of £100 off the UK price.
But the UK price drops by at least £85 if you give up your old camera to SRS for example, and I for one have got several of them (if only they'd take more than one!)

So I'm another who wouldn't do the Australia import thing.
LOL, if he'd take more than one I could buy a K3 in film bodies without having to part with any of the ones I actually like!

caveat emptor

I was in Gran Canaria a few years ago and got pestered by every dodgy camera shop owner who spotted the Pentax strap around my neck. When I got home I discovered there had been a massive bust of fake kit.

My wife did manage to get a good deal on an Optio S4 many years ago, but it took her a whole day to beat the guy into submission to actually sell the camera. It seems the trick in use there was he had one Pentax, one Canon, one Nikon and a massive stock of cheapo knock off crappy things, and he was trying the old bait and switch.

It's not worth the hassle.

The big problem with the rear LCD and possibly an EVF is
that it uses a different aperture to what you are using
on the lens..... so DOF could be miles out. You could have
f/1.4 on the lens and LV is using f/11

This also makes focusing difficult.

not sure where you're going with this one Algi, since the exact same thing is true of an OVF unless you kick the DoF Preview in. Arguably an EVF is better for this, since it can use a longer exposure/higher ISO to capture the DoF Preview image and thus avoid the dark viewfinder associated with that function on an OVF.

Don't get me wrong, even having looked through the highly impressive EVFs on recent Olympus's I still wouldn't give up my Pentaprism willingly, I just don't think this is a useful line of argument.

That's a shame really, the new HD limited lenses are getting superb reviews and three of them are already tested on PU. See the pane on the right.
The only reservation about the new Ltd lenses is that the application of a new coating , however good it may be, is the occasion for a swingeing increase in the retail price - well over £100. I'm entirely happy to do without the claimed marginal increase in contrast when shooting against the light.
they do also have rounded aperture blades, although I admit on the face of it that still doesn't quite justify the price hike.

The tests on PU so far show lenses which break the Y-axis on their MTF graphs, but I haven't checked if that's new compared to the SMC versions.

I think it's unrealistic to expect the noise performance to be better than the K5. With 50% more pixels crammed in, no worse will be an impressive achievement in my book.

I hope that's representative, looks like my K10D at about 400!

you'd need a substantial bag to carry it around in though John
