Other Important Notes:
*I am assuming that buyers have flexible budget.
* Points for profesional level is relative to Profesional camera, so
we can't compare the total scores of professional camera to beginner/semi-pro.
* The review does not take account of personal condition and needs.
For example, if you value ultra small size more than any other feature,
then you should probably choose Olympus E-420 although it is listed no. 5-6.
If you have many Sony and Konica Minolta lenses and equipment, you
might be put higher consideration on Sony Alpha cameras.
* If I make mistakes on the number/facts please correct me.
