I have recently bought myself a Nikon D5100, which came with an 18-55mm lens. I have also bought myself an Opteka baby death fisheye lens, the lens is a 37mm so I also bought a step down ring (55-37). Once i'd set up the fisheye onto the standard lens, I have tried and failed to get the camera to focus. Someone please help? best answer will be awarded!:) Thanks!
