Just to ask the expert and pro in CS. Is "Focus Breathing" a technical or layman term. For years my friends and i have been using Breathing to describe the problem for most macro lens.
But over in CS, Breathing seem like a rare and unknown term for most of us. I started to wonder whether it is a layman or technical term which I used for year. I have not tried asking in photo.net as I know there are lots of expertise here in CS.
Oh and let us compile a list of "breathing" lens. I am interested to know whether a N200M does "breathe" actually. =)
For those who do not understand the meaning please do some research first or restrain from posting. It is not changing length of the lens and it got nothing to do with science that a lens need oxygen.
