I am run and gun; sticking with the MFT Sigma 16mm F1.4 and 30mm F1.4. I don't need better focusing. Will probably just keep the Sigma 60mm f2.8 with me too for occasional use, or it's forthcoming successor. I think there is some in-camera correction though with these lenses, so maybe the 16mm will just have to be tested before settling on it for sure.
