I want to do shots of buildings from high up. There are two ways of doing it, I can think of that will look good, camera movement wise. I can get the constant aperture lens and zoom into a building while trucking and rotating the camera, from another building. Or I can get a long lens that is not constant aperture, to save money, and get the remote control helicopter instead. I just wonder what's worth it more to get professional looking shots, on a very low budget. Thanks.
