for a lightweight system. I have an OMD M-5 and E-PM2. 2 kit zooms and a moderate tele zoom. All Oly lenses. Issues? getting heavy to carry. I have a grip on my M-5. I started with a Sony Nex5. two lenses. they were good, but large. menus were awful i traded that for the M5 i had a Nikon 1V1. 3 lenses. would the Pany long range zoom be sharper, have good contrast and colour?
