Hello, usually I dont' post because of my pooor english.
I'm curious about the statement above, perhaps I dont' understand
correctly, but isn't entrance pupil of 200/2.8=about71mm?
And so for 300/2.8=107mm, 85/1.4=60.7mm.
I haven't seen exit pupil of these lenses, but I think that it's of
smaller diameter than entrance pupil.
Or have I made wrong assumptions on what are entrance and exit
pupils?
