Hey mu43ers, I was flipping through the exif data on some of my photos this morning and seeing once again that I'm hovering through f1.8-f5.6 most of the time on my lenses. Sometimes I will go higher (smaller apertures) like 6.1 or 7.1, but I find the sweet spot for sharpness between f4.0 and f5.6 on a lot of glass. This is a fairly narrow range. The Olympus Pro zooms start (with the exception of the 8mm and 300mm) at f2.8. At the standard ⅓ stop, that only gives you 7 stops to play with between 2.8 and 6.1. Since DOF is doubled on m43, maybe it would make sense to halve the distance between stops to give some greater control. Say, 1/6 of a stop between clicks, at least between the 1.8 and 6.1 range. That might come into play even more when we get 20MP sensors everywhere and diffraction starts becoming a problem around the f5.6 mark.
