The lower tier Nikons use a pentamirror and the upper tier 7 series use a pentaprism.. The P-mirror in the 3/5 series are smaller and they don't let a lot light thru the eyepiece, on the other hand the Penta passes more light through and they are larger to boot.It's all about the money.....
A distinction without a difference when compared with the Fuji EVF's. The EVF lets you see your finished image before you take it because you are "looking through the sensor" and not at a mirror image.
