In the medium focal lenght I also own the 14mm f2.5, the 14-42 x as well as the 14-42 v1 kit lens, but unless I'm shooting wildlife the 20mm stays on my camera 80% of the time. For a while the 14-42x was my go to lens, but since getting the 20mm a year ago the 14-42 doesn't get a look in. The 20mm's mix of sharpness, size and aperture makes it my favourite lens. But am I missing something? Has anyone given up the 20mm in favour of another general purpose lens?
