First review of the GH3's kit lens? Panasonic 12-35mm GX Vario F2.8 In: Cameras Posted May 22, 2012 Andrew, when you wrote that the panasonic lenses have "a continuously variable iris (again for video)" do you mean that the iris compensates as you zoom in (jumping in ca. 1/3 stop increments) or that it seamlessly compensates like on a video camera? My 14-140 has some annoying density shifts as I zoom. Is there a way to get rid of that (besides buying this 12-35 f2.8 lens)? Thanks.
