I don't think you're confused. In fact, your logic seems pretty sound. Since f/stop is not an absolute measurement but a proportion, yes, long lens collects more light from the same subject angle...

When digitizing B&W negatives I consider getting the linear source image of utmost importance...

Well, despite the fact it wasn't designed for fresnel screen, there are two separate steps in the back wall, a pair of vertical and a pair of horizontal. The horizontal ones are deeper than vertical....

I'm using a Chamonix 45N-1 4x5 camera which comes with a fresnel focusing screen. The screen is set up on the lens side from the ground glass and the grooves are also facing the lens. It is a plastic...
