I recently returned to the medium format world by buying an RB67. I have had to ask several questions to refresh my memory as to its use. Without exception the replies have all been helpful and courteous. It reminds me of Nikonians where I am an active member. By contrast there are other websites such as photo.net where the responses can get downright nasty. There was one I saw recently where someone was asking about the image quality of two lenses that he owned. One of the first responses was, "Then why don't you try it out for yourself?"
Anyway, thanks to this group for your help.
