The camera is mounted on the tripod. The telephoto lens is mounted on the camera, with no additional support. Is this safe or stupid?
It seems like this would put a lot of stress on the tripod mount and on the lens mount. Are these mounts designed to support such use? How heavy of a lens can be used this way?
These lenses come without a tripod mount. I know there are third-party support mechanisms. But are these lenses safe to use on a tripod without additional support?
