For "wide on a budget", I'm far more interested in the Pano 14mm + DMW-GWC1 ... which is effectively 11mm. The Pano 14mm is a useful and underrated gem. Adding a ~$100 wide convertor, that seems like a no-brainer to me. And, I assume, AF would still work? Would love to see a comparison between this and the Oly 12mm. I'm sure the Oly would smash it, bit maybe slightly less value and usefulness.
