Until I got the GX-7, I never had a camera with native focus-peaking (although I've used the Art Filter setting on the E-M5 as a good alternative). I really like the way Panasonic executed this feature; it's such a breeze to use my old Pen-F lenses on the GX-7, and they are sized perfectly for the body. A few shots with both the Zuiko 38mm F1.8 and the 25mm F4.0. I've been giving my OM lenses a test drive as well, and they are great also on the GX-7. That said, the OM lenses feel more balanced on the E-M5 + grip. The Oly lenses I tested today, with GX-7 and Pen-F; can't wait to test out the 70mm F2.0 once I get it back from repairs.
