Ive got a Nikon D5100 with the stock 18 to 55mm lens. Basically what I am wanting is the peephole effect, you know where its like a round image that looks like you are looking through a peephole, and it's kind of like a bubble effect. I want one of the lenses that just screws onto the current lens that I have, but all the fisheye lenses I find are for far away wide angle photos, I want the bubble effect, not a long wide angle. How do I achieve this and what lens do I need?
Added (1). Okay but how do I adjust the camera to where the shot is in a circle instead of a rectangle, do I need to zoom way out, or adjust the settings of the camera?
