}Explanation
Formula: f_number = equivalent_f / 0.79. Why: this page keeps Medium format 44x33 fixed, so crop factor and sensor width stay explicit for every calculation.
Medium format 44x33: a sensor profile with crop factor 0.79 and sensor width (horizontal) 44 mm, used as the fixed framing basis for this page.
Equivalent aperture (f-number, DoF basis): a camera-equivalence quantity in this family that depends on the selected crop model.
Aperture (f-number): a camera-equivalence quantity in this family that depends on the selected crop model.
This route is useful when you know the full-frame depth-of-field equivalent and need the actual aperture on Medium format 44x33.
This page is sensor-profile dependent rather than universal because camera equivalence changes with sensor geometry (Medium format 44x33).

Questions & answers
Frequently Asked Questions
Which sensor assumptions are fixed for full-frame equivalent f-number to aperture f-number?
Full-frame equivalent f-number to aperture f-number is fixed to Medium format 44x33, crop factor 0.79, sensor width 44 mm.
How do I reverse eq f to f for Medium format 44x33?
Use the opposite-direction page for Medium format 44x33 to convert aperture (f-number) back to equivalent aperture (f-number, dof basis) with the same sensor assumptions.
Can full-frame equivalent f-number to aperture f-number replace full lens-design simulation?
No. Full-frame equivalent f-number to aperture f-number provides framing and geometry approximations, not full optical-model behavior.
Does equivalent f-number change exposure?
No. Equivalent f-number here is for depth-of-field comparison only. Exposure (light transmission) does not change.
