Small, yet high quality circular fisheye converter for Nikon high-end Coolpix cameras. Was giving a 0.21X factor and producing a very crisp and detailed image, covering 185° of fov. Was largely used to stitch VR bubbles in 2 shots with ipix software. It was then used with many other cameras and adapted in many different ways because of its quality. It has a 28mm standard filter diameter
