Lens board mounting is a routine service that needs to be done right. It is often expected that lenses, as supplied by the manufacturer and fitted to stock shutters, will be mounted to the view camera lens board by the photographer. Accordingly, a lens board with the right sized hole is needed to fit the lens to the camera. S. K. Grimes can bore out the lens board and makes sure the lens is installed correctly and quickly so that you can start photographing as soon a possible.
