Back when I started to shoot 8x10, my first lens was a 12" f/4.5 Wollensack Velostigmat Series II? in a Betax shutter. Front of lens could be rotated (extended out if I recall) to give you different (numbered) levels of "soft focus". Does anyone know if this was extending out only the front element or was it extending out the whole front group of elements?
thanks
