Sidelighting effective aperture

Web4. Effective aperture is the size, in terms of diameter, of the diaphragm opening as viewed through the front element of the lens. It is the apparent diameter that is used to calculate the f-number for a given aperture setting. For instance, if you have a 200mm lens and want an aperture of f/4, the effective aperture needs to appear to be 50mm ...

WebFeb 16, 2024 · f-stop x (1 + Magnification) = Effective f-stop. So, using this equation, we can figure that if working at a 1:1 (1.0x) magnification at f/4, your effective aperture will then be about f/8 (or 2 stops slower). This equation is just an estimation, and if even more specificity is needed then the equation can be expanded further to:
