This material has a lower dispersion coefficient (light scattering) than the glass used for budget models. As a result, chromatic aberration (iris at sharp transitions from dark to light) is significantly reduced. In addition, a clearly defined refractive index of light avoids vignetting (the phenomenon of cutting off the light beam at the edges), which provides a uniformly bright image throughout the field of view.\u003c\/li\u003e\u003cli\u003e \u003cstrong\u003eAspherical lens elements\u003c\/strong\u003e Clarity across the entire field of view is a vital element for comfortable viewing. To achieve this, PENTAX uses aspherical lenses.
