    Re: June Portraits

    I forget if there is any movement with this lens but raising the front standard may put the sharp centre point higher in the image. Or is it lower; no I think it is higher.

    What Pere is saying is that the rear node is one focal length from the film plane when focused at infinity. I think. Which is OK if you know the focal length already.
