Hello everyone,

I have a simple design in my head but I feel it is a bit silly and way more complicated that it seemed.
So I have a Goerz Celor 1B, 180mm lens. It is the one with a focusing ability from less than 2 yards to infinity, so I thought that if I would build a box around it similar to a pinhole camera box and would place the film plane 180mm from the iris and focus the lens to infinity then it could result in a sharp image on the film plane. So if I focus with the lens to desired distances it will give sharp images. No ground glass, no bellows just the negative inside the box. The lens should cover 5x7. The core idea was to decrease the extra long exposure times of the pinhole and use a lens instead. Is this idea plain naive?
