I just relized that I mixed up the terms Parfocal and Varifocal in that posting!


The correct version:

In case is true that Varifocal lenses have less abberations, the ability with Parfocal lenses to focus with a long FL and to zoom then back to a short FL, and by this gaining higher focussing acuracy, might compensate in some cases for any better lab-performance of Varifocal lenses.
