Deciding whether or not to keep this lens. I thought it might simplify my life, but once again, shallower depth of field rears its ugly head and thinking about shooting groups of people at different distances from the camera, I think I'm better off with my micro43 equipment, even though it isn't as good at controlling higher ISO visual noise. Just for the heck of it I tried to take a similar picture with my 20mm Panasonic lens on my GX7 (because it focuses faster on that body) and will post it after this one. Update: RMA received from B&H. It goes back tomorrow.
