Hi,The number of megapixels alone, is no guarantee of heightened photographic performance.
- Optical aberrations occur
, when points in the image do not translate back onto single points:www.cambridgeincolour.com/tuto…- Have you ever noticed that lens descriptions sometimes refer to the ability to “render color”?improvephotography.com/48493/h…
.. yes, Lenses do not form perfect images, and a lens always introduces some degree of distortion or aberration that makes the image an imperfect replica of the object. Careful design of the lens system for a particular application minimizes the aberration. Several types of aberration affect image quality, including spherical aberration, coma, and chromatic aberration.
