I've currently been using a Sigma 12-24 zoom (first version) for extreme wide angle shots (mostly landscape applications). Sigma has replaced this lens with a new version that I hear is both sharper in the corners but has worse image distortion. In addition, I've heard people using the VC 12mm lens on the A7 cameras. My question is can anyone provide a comparison of either of the Sigma lenses to the VC 12mm? I guess I'm interested in its use as a landscape lens on an A7S (but any comparisons are meaningful). Just looking for opinions, so even if you haven't performed in-depth testing I'd be interested.

John
