Several sharp lenses - Samyang 14mm XP, Samyang 50mm XP, Sigma 28mm Art and Sigma 40mm Art – have noticeable spherical aberration. I have the Samyang 14mm XP and Samyang 50mm XP, and I want the Samyang 35mm XP, but I hesitate because I suspect it will have this characteristic also.
These are all fairly high quality lenses and I understand that compromises must be made when designing lenses, so I am curious what compromise results in spherical aberration.
