A optycznie Ai-S 20/2.8, AF 20/2.8 i AF-D 20/2.8 to te same szkla, moze w tych nowszych sa gorsze powloki dlatego slabsze.
Cytat ze strony ponizej
"The current version of the Nikkor 20mm is an autofocus AF-D 20mm f/2.8 lens that has an exacting optical design with the last version of the MF Nikkor wideangle lens introduced back in 1984. "
