I have a Graflex Super Graphic with a optar 135mm f 4.7 Wollensak lens with a Graphex shutter. I have read the threads and examine the manuals and and set the Infiniti stops. The camera now focuses like a dream through the ground glass it takes almost nothing to focus it. However the rangefinder is another matter when I look through it I can see the image move but the image quality is poor and is just barely there. Any help you can provide me with would be appreciated.
