I tested the K-r for ePHOTOzine and I was very pleased with it. I wouldn't hesitate to upgrade to it from the K100D.

The only reason I went for the K-5 was weather resistance. Otherwise, I actually prefer the ergonomics of the K-r.

It's been suggested elsewhere that these were not finished products, but only parts of planned images, in which case a small figure in the frame could be pre-planned to fit in with something else. If this is the case, someone may be furious that the images have been leaked....

If you can still find a K-r then it's a great camera. Your 50mm lens will work on it just fine.

The K-5 adds some features such as weather resistance, but you could also wait for the new K-30.

If your budget is tight consider buying second hand. With new cameras about to arrive there may be those who wish to buy new and move along their used but still spotless K-x and K-r cameras.

The basic point is right, providing of course we do actually change our viewing distance. The resolution of 35mm film is about right for a 16"x12" print, so whatever that equates to is the right number of MP.

There is indeed a huge difference between a monitor image and an A3 print. Few of us will ever print to A2.

The print medium is far more demanding and reveals all sorts of defects. If though we never print and only view on the monitor and on the web, then that's a whole new ball game. We may not need more than a 6MP camera for that, and possibly less if there's not much cropping to be done.

Compacts and even mobile phones can produce very acceptable web images, given the right conditions and the right photographer.

It is much easier to use a DSLR though, I find it so anyway.

Back on topic please...

I think the Pentax converter needs f2.8 or faster lenses to work properly.

JAK alludes to the fortnightly competition being replaced by the new monthly competition that is already running in the Gallery area.

If you use the video output from the camera you will be able to display menus and playback images. Not sure about LiveView, although that should work too.

It's still under warranty, so the dealer is responsible for warranty repair.

Just check first that the batteries are still in good order. Rechargeables do have a lifespan, maybe 1000 recharges, and will eventually fail to deliver enough power. This could cause mirror lockup.
