I want to try out the new Pentax APS-C with Full Frame OVF,
But I'm curious about how the lenses work with OVF.
If I use an F1,4 prime, will the OVF literally be 4 times brighter than if I use an F2,8 zoom?
If yes.
Will there be a point where the aperture will make the OVF sight brighter than my regular eye sight?
At which aperture is that point?
