50mm prime vs Zoom, +1ev to expose the same?

Just so I learn, how does the focus screen affect the exposure? I thought the focus screen was simply a preference of how you want your eye piece to appear?

I'd also be interested in what you guys think about the differences between those photos. They were taken back to back, only a lens change was made (and the +1ev). I would have expected a little more from the prime vs the kit zoom or maybe I am missing something? I am new to DSLR.

Thanks!

I have the standard kit zoom 18-55mm 3.5-5.6 AL II pentax lens and also the Pentax FA 50mm f/1.4 prime. It seems that to get the same exposure as the prime on the zoom, I have to over expose the zoom by +1.0ev. The exposure looks good. If I leave it at +/- 0.0ev, then the zoom always looks under exposed.

Is this normal for the K20D and the kit zoom?
