Hullo everyone !
Say I have a LF lens that - once mounted on a flat board - from nodal plane / point to film plane needs 7 cm and from last lens to film plane needs 2 cm. If I need / want to mount this lens on a focusing ring large - say 4 cm - the distances of nodal point and last lens to film plane will be moved 4 cm forward the front of the camera or not ? Will the build of focusing ring make the difference or not ? Schneider - say - focusing ring will keep the same distances from film plane and "commercial" focusing ring will not ?
Say that all distances when lens is mounted on focusing ring are moved forward - what will be the solution to regain the original focusing distances ? Maybe a recessed board ?
Thank you for any answer - clue - documantation link..
Bye
