“ Da come ne parlano sembrerebbe adottare uno schema simmetrico, o forse un semi-simmetrico, la qual cosa mi fa sperare in prestazioni molto elevate senza ricorrere alla scappatoia della correzione on camera delle varie aberrazioni. „
Ci sono sicuramente delle correzioni in camera
“ The RF10-20mm f/4L IS STM additionally supports the new Peripheral Coordinated Control2, which effectively compensates the peripheral blurring that tends to occur with ultra-wide-angle lenses. This works with the optimised lens configuration and in-camera correction to control distortion and chromatic aberration throughout the entire zoom range. This results in outstanding image quality that is on par, if not better than that of the EF11-24mm f/4L USM's stellar reputation. „
