very interesting and intriguing conversation; and very educational too, I might add. Thanks OP for such an interesting topic. Reminds me that I once quoted someone who asked me why I did not choose the C* brand, I say I want to have that 77mm lens. He thinks that I was weird as he thinks that there is no such lens existing.
