As I understand it, it is not the pixel shift technology that there is anything wrong with, but rather Pentax's implementation of everything else around it. Pentax could easily have implemented a proper EFCS in LV mode without slamming the mirror up and down. Also EFCS in mirror-up mode with a proper delay should have bern easy. Olympus has implemented a similar pixel shift technology without any of Pentax's limitations in the OM-D series. And no, it doesn't matter if mirrorless or DSLR regarding a properly implemented pixel shift technology, since the LV mode on the Pentax K-1 should have bern able to work exactly like a mirrorless OM-D.
