Am I the only one bored to death with pixel shift ? Who cares. If you want everything in focus use an iPhone or any other small sensor or a 14mm lens set at f5.6.
On the whole photography is about 'subjects' -- photographing subjects and isolating them from, while still being in their environment or background.
Pixel shift is a step forward for technology but 3 steps backwards for art.
It's the equivalent of a bad chef who has no vision and instead of adding a few spices, adds them all.
