In addition, as I have already pointed out above, when a lens is stopped down, the lens diaphragm can cause internal reflections. Since 70-200mm zoom lenses have a complex design with a dozen or more elements, you can see that pretty much every lens suffers from veiling flare and ghosting, with Nikon 70-200mm lenses leading the game with a minimum amount of ghosting in images. Typically, the more elements, the more ghosts will appear in images. The total number of these ghosts varies by how many elements there are within each lens. Take a look at the below portrait that was captured using the Nikon 58mm f/1.4G lens:Īside from the visible veiling flare visible in the images, you can also see various circular artifacts/orbs in each image – those are referred to as “ghosts”. For example, Nikon’s proprietary Nano Crystal Coat technology used on professional-grade lenses helps a great deal in keeping veiling flare under control. High-quality lenses with multi-coated lens elements can help in reducing veiling flare. This results in very noticeable haze/lack of contrast, where dark areas of the frame become brighter with bleeding colors and appear washed out. absent from the image, but its light rays still reach the front element of the lens. Veiling flare usually occurs when the bright light source is outside the lens angle of view, i.e. While both typically go hand in hand, good lenses with multi-coated lens element surfaces can significantly reduce veiling flare in images. While traveling through the lens, light can also be reflected off the lens diaphragm if it is stopped down, resulting in even more noticeable flare.Īlthough the above illustration shows lens flare in general, manufacturers and photographers usually identify two types of lens flare: veiling flare and ghosting flare. As you can see, regular light rays (red) follow their normal path, directly reaching the image plane (green), whereas bright light rays (blue) can split and reflect off lens surfaces and end up in different parts of the frame (dotted blue).
