Hey guys. New Samsung NX1 owner / user here. Currently have NX mount Rokinon 35mm and kit lens. Looking for the best combo of lenses / adaptors of the camera. Seem to be quite a few fans of the Sigma 18-35mm with a Nikon/Canon adapter. Can any of you weigh in on which lenses you think result in the best image for this camera? Less than $1000...
