I am having a problem today.I use an Ebony SV45 and just bought a Schneider Supe r-Angulon f8 65mm lens.Going out into the street with views for several hundred feet I could not find the focus for this lens.I had the camera draw at maximum w ith the front and rear standard blocks touching....the maximum draw,with wide an gle bellows.Am I doing something wrong,or is maybe the rear element the wrong on e?I am baffled and could do with advice.Thanks in advance for your wealth of kno wledge.A.
