CA is visible to me and the the zoom appears pretty poor compared to the A20, it certainly wouldn't replace my A20 and I'm not that fussed with the performance of the A20 relative to the A15 or A16F. Josteins results (great page J, thanks) confirm my tests over the years particularly the 645 lens results.
