The question, obviously, is: Which one gives better "perspective?"
Irrelevant when you are familiar with equivalent focal lengths of lenses, as I am. The camera body then makes little difference.
But the great thing for you is that with this camera you can switch between FX and DX; think of the myriad number of possible perspective tests that you can do!!!
The optical path to the PDAF meter is not changed by removing the OLPF filter, but the optical path to the sensor is, so AF calibrated on the basis that on OLPF is present will be slightly inaccurate if that OLPF is not present.
