Are you good building things? Many have started with pin hole cameras, either wood kits or cardboard. You don't pay for a lens or a camera. The field of view or angle of the view depends on the size of the hole and how far back the film or printing paper is.
When I took a Photo 1 course in college I made a pin hole camera of a 12 quart oil carton. We laughed because it had a zoom feature. The lens or pin hole was fixed, but the printing paper was held in place by a sliding mechanism. The further I slid it back from the pin hole, the wider the angle. You can also make one using an 8x10 film holder and a fixed pinhole.
