Is lens flare and ghosting affected by lens type?
Most of us use compound lenses made up of several lens elements rather than a single element. Because there are more internal surfaces from which light can reflect, the potential for flare increases as the number of elements in a lens increases. Zoom lenses, for example, often contain more lens elements than fixed focal-length lenses. Therefore zoom lenses are generally more susceptible to lens flare than fixed lenses.
