The Luminous Landscapes review of the 645D vs the Phase 1 (and Canon 1Ds mkIII) was also pretty good - to quote the summary:

I don't think the difference is anything remotely significant. I remember the k-5 came out with a slightly higher overall score. But who would actually notice in real life images?

I thought this was an interesting blog post from Gordon Lewis - a K-7 user who has now bought a D7000. His reasons for keeping his current camera, a K-7 (and awaiting the chance to test a K-5) are as interesting as the reasons he went for a D7000 rather than a K-5 in the first instance.

Great position he's in, to be able to run two systems simultaneously!

That's very nice bokeh Don. I think it is beginning to make more sense to keep hold of the 16-45 and a couple of primes than upgrade the zoom to a constant f2.8 (even if I had the money, I would take the Tamron over the Pentax one I think!) The K-7 just cries out for a nice prime lens to make the most of it's compact size and excellent IQ.

He was probably on his way back from the clubs, Spider.

The first two shots are the most interesting to me. In fact the 2nd, in contrast to what Matt says, shows the real enjoyment a cigarette can bring - a brief time-measured moment of escape. Often there are very few other reasons just to stop and just observe, or let your mind wander, for the length of time it takes to have a quick fag. Is that worth risking cancer and heart disease? For me, no, but I can understand the pleasure. And, my mum smoked when I was growing up. In the car even! I'm not dead yet lol...

Lol we scrambled over each other to help - typical of this forum

My biggest quandary wouldn't be what to take so much as... what to bring back!

I'm looking around for the person you think you're arguing with, Don! I certainly agree with you. Although personally I'm happy with MF and definitely prefer mjpeg capture becaus eit doesn't make me need to buy a new PC, I can see that a lot of people would rather their camera behaved more like their Sony Handicam and probably have a bit more computing power than me to edit their videos (if indeed they ever edit them at all).
