The 18-105 has up to 6.7% pincushion distortion - a reverse fisheye if you will. I wonder how good the 18-135 is? Maybe Klaus is going to test it some day but there's almost certainly some auto-correction trickery going on, the Sony E system is relying upon this even at the very top of the food chain.
