Today I tried to use 210mm lens on Wisner 11X14, then I realized that I only can made bellow to about 360mm (14 inches). there are two screws on each side of bed that block the movement to make bellow shorter. I checked manual of Wisner 11X14, it said minimum focus for normal bellow is 6 inch. Can someone tell be how to use 210 lens on it?Click image for larger version.
