Sensor sites do not mean pixels on almost all the cameras being talked about. The DSP in the camera uses the information from the sensor sites to create pixels used for recording. In the case of Panasonic the sensors are pixel shifted and the data used by the DSP to create the selected recording output. In the case of Sony Z5 and NX5 the array is a set of diagonal sensors roughly twice the area of what would be a 1920x1080 pixel on the same die size. If one looks at the array one can visualize pixels created using data from 4 surrounding sensors for a pixel at sensors intersections and a pixel at the center of each sensor but half the size. Outcome is 1920x1080 pixels for each colour.
Corey, from all your questions I still have no idea of your camera or editing experience and exactly what output you are looking for in your project. Spending money is not a good way to start as others have suggested.

i found this camera locally used for 3k....is this a better buy than a ex1r?

Used Sony | DSR-390L Professional 1/2" DVCAM | DSR390L

The DSR-390 is not an HD camera, so if you're looking for HD, it is not a better choice than the EX1r.

oh ok, thanks
