[LargeFormat] Macro photography and movements

[philip lambert]

Is there any difference in these difficult working situations between
movements pivoting on the lens axis and one with movements pivoted from the
base/rail?  Quite apart from this, macro work is made more tricky when
focussing at the front standard, as  this changes simultaneously the film to
lens distance and the lens to subject distance. Focussing movements at the
rear standard (like a Sinar) leave lens to subject distance unaltered. This
feels easier. Any experts out there like to advise please?
