Zuiko versus M.Zuiko lenses

Hi Jim,

true, I was thinking more in optical terms. The only lens which could be classed as HG or above on build would be the 12-50mm and optically it doesn't cut it. I don't think the old grading system works for m4/3's but there are lenses that are HG and possible one or two that could be classed as SHG in optical terms. I forgot the 60mm which could probably be classed as SHG standard although the old 50mm F2 wasn't (though it's performance is right up there). I think the SHG lenses were partially hand made so maybe that's another distinction.
