A: The Rokinon DS cine lenses are certainly an adequate route for cine style lenses for their cost. The zoom lenses you have listed are good lenses, especially if doing event or run and gun style work and looking for a single lens that encompasses a wide range for quick focal length change, but for a low cost cine designed lens that does a fine job, Rokinon is a good route.
