No surprises here.
The tilt is not in the lens it is at ST8300 sensor.

Full frame lenses will perform better on smaller sensors. though - because of obvious reasons (smaller sensor, aberrations stay outside the corners). However, they will also be much more expensive. Which means, DSLRs with smaller sensor (not full frame !! ) will not capture those aberrations.
