Also, I would like tp point out the AF Nikkor 105/2.8 was released roughly 2
years later than the FA100/2.8, which itself is a copy of F100/2.8

By comparing the diagrams of similar optics from different manufacturers, it
is not difficult to see that they are very different (even those popular
50mm). I would be very surprised when 2 designers came up with the the exact

You can't tell from the diagrams. They are very simplified, do not

They might fine tune them differently, but when the diagrams look identical,
I'd say they are copying each other. Besides, the CAPA 2003 len

It's not automatic; you have to play with settings, but I've seen
