And Zeiss managed to produce one of the worlds lowest linear distortion ultra-
wide angle lenses, the Hologon, using a virtually symmetrical design. Coma 
is near non-existent in this design as well. No retrofocus ultra-wide that I 
have used or owned comes close to its performance, discounting speed and 
natural vignetting (which is readily corrected) of course.
