And here's another question:
I liked the Pentax LX I used so far mainly because of that feature: to be able to see from above how the frame looks. It seems like anyone with a digital camera is always using the viewfinder. As this seems like a head ache to me, there must be a darn good reason for this. If you're using AF, focus is not the reason.
Do YOU use the view finder? And if so - why? And how important is the screen resolution then?
Thx (and thanks for the 129450 comments you already posted :) It helps!)

Alright let me answer a few of them:
What is an SLR?
A single lens reflex (SLR) camera distinguishes itself from other cameras by enabling the photographer to see the image exactly as it will be captured on the film or sensor beforehand through a viewfinder. This is done via a reflecting mirror that passes the image through a pentaprism and onto an eyepiece through which the photographer finds the view. When the camera trigger is pulled, the mirror lifts out of the way, and the shutter opens up to let the light pass through onto the film or sensor, capturing the image. Now that we have a basic understanding of the mechanics of an SLR camera we can now discuss the sensor.
* 1) Lens
* 2) Primary Mirror
* 3) Primary Mirror During Snapshot
* 4) Focusing Screen
* 5) Pentaprism
* 6) Viewfinder Lens
* 7) Digital Sensor
* 8) Sensor Filter
* 9) Shutter
* 10) Relay Mirror
* 11) Autofocus System

The focus at this point is simply faster and better at getting it right than live view AF,
To use your viewfinder gives your better control of your camera, you can get away with lower shutter speed, aim better, and if you need to MF you can see if you are getting the right thing in focus. And you can use the DOF(dept of Field) preview to see how much is in focus. I do use live view shooting only if I have to and sometimes on tripod studio shots
For most pictures the build in flash will do and you can buy or make a diffuser to reduce the glare that they can make, but a larger external flash opens up a new world of exposure, I will show you picture my 9 yr old son took of his toy motorcycle

This could not be done with your build in flash
Anyway I am in Camera Sales and the D5000 is by far the best seller that we have, but I would recommend the D90 if you plan to more involved with photography, it is slightly better made, I would feel that the larger body is easier to control, The 18-200 lens is OK if that is all you plan to get, It is one of them jack of all trades but not really that great at specific tasks
Anyway this is maybe enough for this time
