A lot of lens already have groups of elements while moving the focusing helical gears, will move on a non-linear scale independently with other groups of lens. I'm not convinced that with an internal shutter this design is impossible. Also, with this float integrated with the helical gears, you get variable float, which in principal would be even better. If the internal shutter impose such difficulty, than I would say all Hasselblad lens with shutters are a compromise due to this limitation. - --- Jim Brick <jim@brick.org> wrote: > At 06:48 PM 2/10/2002 -0800, Henry Ting wrote: > > >I cannot > >figure why Hasselblad cannot design an internal > >mechanism to change the floating elements based on > the > >focusing distance instead of forcing the > photographer > >to do it.
