While comparing the 85mm f/1.4G to the 85mm f/1.4D I noticed the lens hood size is noticeably larger on the new lens. You can see the difference down the page here
While I could understand a little difference, I would expect for them to be most effective, the same focal length would have roughly the same lens hood from lens to lens. Why the difference? Or are my eyes just fooling me because they're constructed a bit differently ?
