I recently purchased a Graflex Crown Graphic with two lenses: a 90mm 6.8 Spiratone Weitweinkel Anastigmat and a 165mm 6.3 Ilex-Calumet Caltar and a couple of film holders. I'm having trouble focusing using the ground glass, all I see are the image in round circles but complete image on the ground glass. It gets better the longer the distance between myself and the camera but that defeats the purpose. It's worse with the 90mm lens. Am I using the incorrect lens board? It's a standard metal plate one with 'Special' written on the top. I'm new with large format but not a complete novice. I have a monorail and recently had a Graflex RB 4X5. Any help would be appreciated. Chris M.
