Why you cannot accept that distortion is just distortion. But OK, distortion is one of the aberrations but usually dealt separately as barrel or pincushion distortion. There are many types aberrations, like the basic seven aberrations: spherical aberration, coma, astigmatism, field curvature, distortion (yes, here it is), chromatic aberration (longitudinal and lateral) - and then we have the higher order aberrations like the Seidel aberrations... and the fifth order aberrations (the nine Schwarzschild aberrations) and so on ad infinitum. You would impress more if you could spell "aberration". All the best! Raimo K Personal photography homepage at: http://www.uusikaupunki.fi/~raikorho
