I have been shooting with the Nikon 200-400mm f/4 VR lens for the last 4-5 years and I can assure you that the Nikon 300mm f/2.8G VR II is overall a better lens to buy (unless you shoot large animals from a close distance, like bears in Alaska).
Simple eye in invertebrates. A simple eye (sometimes called a pigment pit) refers to a type of eye form or optical arrangement that contains a single lens. A simple eye is so called in distinction from a multi-lensed compound eye, and is not necessarily at all simple in the usual sense of the word. The eyes of humans and large animals, and camera lenses are classed as simple because in both cases a single lens collects and focuses light onto the retina or film.
