There are three Hexanon lenses with multilayer lens coating, and these late additions to the product list were the fish eye, the 21 mm f 2.8, and then there was a tele also carrying the UC tag (ultra coating or something similar). Was it a 400 mm f 6.3 or what was it? Is it superior to older Hexanons of similar focal length?

Thanks,

Re: UC

This much I know: UC is "ultracompact," and the lenses were designed to be smaller. I'm sorry, I don't know about optical superiority.
